How Human-like is Komodo 14 Human?

    In a recent post on my chess Blog I mentioned that Komodo 14 has a personality called Human which is “designed to play more like a human Grandmaster on a high level or like an amateur taught by a Grandmaster on lower levels.” The Komodo site explains that as a result “it may well perform better against most humans than the default engine on the same level.” 

    At the time of THIS game, Boris Baczynskyj was rated 2264 (Master) and I would expect that the Weighted Error Value scores would be lower when annotating with Komodo 14 Human, meaning that the closer to zero the score, the closer the player’s moves match the engine’s. 

    Analysis with Komodo Human showed Baczynskyj’s Weighted Error Value was 0.73 while Reshevsky’s was a precise 0.26, meaning that Reshevsky’s moves very nearly match those of the engine. Baczynskyj’s Weighted Error Value was 0.76 which is actually quite good. 

    One would expect the Weighted Error Value to increase when analyzing with Stockfish 16.1 simply because it is a stronger engine and humans would be less likely to select the same moves as the engine. 

    Using Stockfish 16.1 saw Reshevsky’s WEV to go up just a bit to 0.36, but Baczynskyj’s improved a bit to 0.69. I can’t explain it. 

    In a short match pitting Stockfish 16.1 against Komodo Human with a time limit of 5 minutes per game, Stockfish won 3-0. 

    In annotating one of the games (below) using Stockfish, it’s WEV of its own play was nearly perfect which is no surprise. What is interesting is that Komodo Human’s WEV was 0.72 which is pretty close to Reshevsky’s in his game against Baczynskyj.

    I am not sure what to make of all this except to sat that Komodo Human is clearly not close to Stockfish 16.1 in strength, but it appears that id does play at the Grand master level, are the moves human-like? I can’t say. 

    To me this brings up the question, why pay for an engine when a stronger free program is available. Additionally, I do not see any benefit to the different Komodo personalities; they are, I think, sales hype.

Tartakower's Best Games

    Despite the glut of chess material that's available today and the use of computer chess programs, for me it’s still a delight to set up the pieces and pull out a book of somebody’s best games or a tournament book and play over the games.

    One collection, actually a two volume set, is the best games of Tartakower. You can’t buy them any more, but you can purchase My Best Games of Chess 1905-1954, the 21st century edition, in paperback on Amazon for $31.80 or the Kindle edition for $11.49. One caveat – the Kindle edition gobbles up a lot of space...45 mb. 

    Savielly Tartakower was a unique player and writer and you will love playing over all 2167games. But, if you don’t want to spend any money you can player over all the games or download them and make your own notes using a chess program at chessgames.com HERE.

What's the Best Chess Software?

`I received an e-mail the other day from a reader asking what chess program I recommended. The answer, I suppose, depends on what you want to use it for and how much you want to spend. I have several programs on my laptop: Chess Aquarium 2014, Ches Aquarium 2020, Chess Assistant 18, Fritz 12 and Fritz 17 and SCID vs. PC. 

    For my chess Blog I originally did all of my analysis using Fritz 12 and posted the games using various online sites, most of which are now defunct and so the games on the Blog posts are no longer visible..

    The next way to post games was to analyze with Fritz 12 and post them with Aquarium 2014. When I got Aquarium 2020 there were problems posting the games, so it was back to the 2014 version. 

    Then Fitz 17 came along and all the problems associated with analysis and publishing game on the Blog disappeared. Today Fritz 17 is all I ever use. Personally I think Fritz is more user friendly than Aquarium. Both have pleasing and customizable layouts. The latest version of Aquarium is 2024 and it can be download for around $50.00. 

    While the functions overlap, Fritz is basically a program you can play against and use for analysis. ChessBase is a database management program. 

    Both programs let you access a database in either ChessBase or PGN, format. The ChessBase format is designed to save a huge amount of game related data.

    When playing against Fritz you can adjust the level, it will give you hints and talk to you. You can also do a full analysis (including adding alternate opening lines with the game’s final results) plus you can add your own notes. 

    The current Fritz 19 comes in three versions. The Basic version has some specialized opponents: Attacker, coward, swindler and an endgame wizard. Cost: about $98. 

    Fritz with Fritz Powerboo which contains 25 millions opening positions. Cost: about $150 

    Fritz with Opening Encyclopedia which is more sophisticated and offers a number of other features. Cost: about $217. 

    ChessBase performs searches of games based on players, exact positions, tournaments or material. It also will create Opening trees of variations, tell you how successful particular lines have been and it will enable you to do training exercises. Unless you are a professional or just wants a top of the line program this one may be overkill. Cost: about $272 

    Chess Assistant 24 is a program for managing games and databases, playing on the Internet, analyzing games, or playing against the computer. To be honest, it’s my least favorite program and I have never used it. Also, I am not crazy about the appearance of the interface. 

    Chess Assistant includes several databases: the HugeBase with over 5 million games. a Guru database which includes games of top players and a Correspondence database of games between notable correspondence players. There is also am Openings database in particular is the Openings database. Chess Assistant 24 (download version) costs about $95, but at the time of writing it’ on sale for about $75. 

    For this looking for something free then Shane's Chess Information Database is unquestionably the best free program available. It can can create databases, run just about all engines and you can play against it or online.

 

Points in Pachman-Van Seters , Hulversum, 1947

https://www.chessgames.com/perl/chessgame?gid=1485712

10. Bxc4 Be7 

In this position it is worth noting the importance of white’s P on a3. It’s important because it prevents the maneuver ...Nb4-d5, blockading the d-Pawn. It also prepares the development of white’s Q to d3 which in conjunction with the moves Bg5, Rad1 and B-a2-b1 make the launching of a K-side attack possible. Nimzovich recommended the plan with the moves Qe2, Be3, Rfd1 and Rac1, but experience has shown it is of little promise. 

11. Re1 b6 

11... a6 is generally played but Pachman felt that the text move is more solid because after 12. Bg5 b5 13. Ba2 Bb7 the weakness of the square c5 would make itself felt after 14. Qd3 Nd5 15. Ne4 and now black’s best continuation is Nf6 (15... Bxg5 is less good because after} 16. Nexg5 g6 17. Rac1 Rc8 18. Rc5 {white is slightly better. 

13. Bg5 Rc8 

Pachman went so far as to give this move a ? stating that black has underestimated the danger that the aggressive posting of white’s pieces presents and black does not have time to develop his own pieces undisturbed. If that sounds harsh, even though Stockfish and Komodo evaluate the position as about equal, statistically after Szabo’s next move white scores a 49 percent winning advantage while losing on 16 percent! 

14. Rad1 Qc7 

Pachman also gave this move a ? stating that the continuation of the faulty plan started with his previous move could have been mitigated by seeking simplification with 14...Nd4 though even then white woud have the upper hand. 

16. h3 

Forestalling any complications that may arise from black playing ...Ng4. 16... Rd7 Black’s play is much too slow. His plan is to double Rs on the d-file pressuring white’s d-Pawn, but it’s much too slow and enables white to make a decisive breakthrough. 17. Bh4 Nh5 and even now the advance of the d-Pawn leaves white with a superior position. 

17. d5 

This is it...the classic lunge!

Fritz 17 Review For Posting Games On Blogger

     I have not done a review on this blog in a long time and last October I did a brief review of Fritz 17 on the chess blog. For years I was using Fritz 12 to do all my analysis and over the life of the blog several different programs were used to publish games. Thus when I got Fritz 17 with its ability to analyze and publish games it was pretty exciting. 

     I have read of several people complaining that the program has various glitches, but I have not found that to be the case. I use it on an old laptop with Windows 8.1 and on a newer laptop using Windows 10 and have never had a problem on either one of them. 

     The program comes with a ton of engines which I don't need because none of them are stronger than the free Stockfish 15. The only caveat with Stockfish is that its evaluations are about twice as high as those of other programs and the lower evaluations of programs like Komodo seem more appropriate. 

     I'm not interested in Fritz 17's 3D boards with ray tracing, playing online or its training features, just doing a full analysis and publishing. It turns out that Fritz 17's analysis returns a tremendous amount of information, some of which I could do without. 

     It inserts diagrams at what it considers to be appropriate places in the game. They are easily deleted by simply clicking on Text After Move and deleting the text that generates the diagram. 

     There are some other symbols and colored flags that appear at various points in the game. I have not bothered to find out their meaning, but there seems to be no way to delete them except by searching through the HTML code and deleting the code appearing in brackets that begins with a percent sign. But leaving them in the published games doesn't hurt anything, so the simplest thing to do is ignore them. 

    My initial problem with using Fritz 17 to publish games was the appearance...all the bells and whistles plus engine output appeared on the blog post, but it was much wider than my column so it bled into the column on the right hand side of my blog page. This was an easy fix...just change the column width when pasting the game into the blog. 

     There is another way to paste the game into the blog that automatically adjusts to the blog's column with, but all the bells and whistles are missing. Nevertheless, I like this layout the best. The only problem was finding documentation on how to do it. 

     It was not until I found this documentation that Fritz 17 became my program of choice for posting game in the blog. Here's how to do it:

 

* Click on Direct Share 

* Select Create a HTML File 

* Assign the game a name 

* In my case my default browser is Internet Explorer and it automatically opens and a pgn of the game appears. 

* At this point right click anywhere on the page and select View Source. A new window opens with the HTML. 

*Just copy and paste this into Blogger's HTML page. 

 

In Blogger the game will appear like this: 

 

   Once I discovered how to paste the games into my blog using this method I changed my opinion of Fritz 17 and I now use it for all analysis and publishing.

     Fritz 18 is out now and is available for download for about $90. I am not sure what's new, but I doubt that it's anything really worth while. If you can find Fritz 17 it should be cheaper. 

     The main point of this review is that I have found Fritz 17 to work well with my laptops and it is a excellent program for posting games in Blogger. It is also an excellent tool for analysis and I honestly do not know why some people have found it to have so many glitches.

Answer to temperature question asked HERE... 

If it is 0 degrees F. and it's twice as cold tomorrow the temperature will be -32 degrees F. 

Zero degrees Fahrenheit converts to -17.78 degrees Celsius. Doubling 17.78 gives -35.56 Celcius which converts to -32 degrees F.

White can only mate on two squares e7 and h8, but if 1.Qa3 black has 1...c5 or 2...O-O-O. If 1.Qa1 then 1...O-O-O. At least that's what I thought, but after 1.Qa1 black can't castle because he made the last move and it must have been with either the King or Rook, so castling is not legal.

Counter Gambits by T.D. Harding

   

  How to win with Black! This is a great book! It's packed with 22 pages, including an updated chapter written in 2001. And, the format is perfect: long-algebraic, bold type for game moves; short-algebraic, light type for analysis. Great diagrams. There are 75 complete games and many more complete games in analysis. It's by Dover so you know it's a good book and the price is only $8.95. 
     OK, so it's old and the analysis on the Benko Gambit, especially, is outdated, but even so reading over the material will at least give you the groundwork to build upon. The Henning-Schara, Budapest, Blumenfield, Albin-Counter Gambit, Falkbeer Counter Gambit and Latvian are covered as well as a few others. 
     If you want some ideas about what to play as Black and like gambits, this book is a good starting place. There are three types of gambits by Black: 1) theoretically sound, 2) risky but worth trying and 3) garbage. And, another great selling point about this book is that Harding doesn’t make the mistake of trying to prove that all gambits are good. He gives his honest opinions and gives many games where Black loses. Not all of his analysis is correct, but that’s not important because you must always do your own analysis!

While the latest version of Fritz is 15, it costs about $80.  And, you are paying for features that aren't really needed...the e-book version of Capa's Chess Fundamentals. This book can be downloaded from various sources in pdf format for free. 
     The Fritz engine still is not as good as the free Stockfish. The "Friend" mode has been reworked, supposedly to make playing against an engine more realistic. The "on-demand video” gives unlimited access to a database of training videos, etc. That's fine, but there are plenty of places online where you can watch some excellent training videos for free. 
     You get access the ChessBase online database with 8 million games. Again, game databases abound. True, not 8 million, but I am willing to bet that most of those games are played by lower rated players. In any case, my 2 million game database (occasionally update) has served quite well. 
     The “My Games Cloud” allows you to access your server games...if you play any on Playchess which requires a subscription after your free trial membership is up. There are more than 34,000 training tasks with the program. Tactical training is free on several sites.
     The highly touted “Let’s Check” gives you access an analysis database with over 200 million deeply analyzed positions. Just a guess, but I'm betting the odds of the database having exactly the position you are looking for are still pretty slim.  Anyway, why not let your own engine run overnight if you're that interested in a position?
     All these bells and whistles are nice, but for most players they are not worth the money. You can go online and purchase Fritz 12, if you can find it, for about half of what version 15 costs. But version 12 is getting scarce. 
     The next best alternative is probably Fritz 14 which is available by download from Amazon Digital Services for $40. You get 6 months Premium membership and a 1.5 million game database which, if you want to take the time, you can add games to it. Then you download Stockfish and maybe the latest free version of Komodo, which is version 8. And, for half the price, you'll have just about everything you'll need. 
     Of course, if you're looking for totally free, then Arena Chess or SCID are both excellent alternatives. And, if you want something functional, yet somewhat simpler to use then the Tarrasch GUI is an excellent choice.

Chess Duels: My Games with the World Champions by Yasser Seirawan

     This is a great book!!   Four-time US Champion Yasser Seirawan provides a fascinating and highly entertaining account of his games and encounters with the world champions of chess including Garry Kasparov, Anatoly Karpov, Bobby Fischer, Boris Spassky, Tigran Petrosian, Mikhail Tal, Vassily Smyslov, Mikhail Botvinnik and Max Euwe. 
     Seriwan presents an in depth look at not only his wins, but his defeats and that's a rare thing among GMs writing books about their "best" games. His annotations are in plain language and they are first class. You can't help but improve by carefully playing through the games and reading his insights and seeing what he was thinking. 
     Besides the games, there are stories and anecdotes galore. There is an extensive introduction and discussion of each opponent, chess politics and other events of the time are also given. Although he never played Bobby Fischer (that was a surprise to me!), Seirawan includes a 13 pages of his views on Fischer that are simply fascinating. But wait! There's more! There are stories about Korchnoi, Reshevsky, Euwe, Larsen and others. 
     Opinion: I don't like spending money for chess books because most of them never get really read, but this one did and it was worth the $30.

The Sicilian Dragon

     The Sicilian Dragon is still a good defense for black! The main lines lead to tremendously complex positions in which both sides attack freely. One slip could be fatal, and a deep knowledge and understanding of the opening is often a decisive advantage. 
     In this book IM David Vigorito focuses on all the critical Yugoslav Attack lines, examining the most important and instructive games in recent years (up to 2012) and highlighting the main developments and novelties for both sides.
     Like all opening books, the material is dated as soon as the book is published, but the author provides a good survey of BASIC theory in this defense which is still a viable option as black. The book is not a comprehensive Dragon repertoire book. It covers 9. Bc4 and 9. 0-0-0 and g4 very thoroughly, so you will need additional resources if white plays anything other than the Yugoslav Attack. 
     The good point is that it is organized with the major variations in bold type and the author provides ample descriptions of why certain moves work out well or poorly, which makes it easy to study.

The Power of Pawns: Chess Structure Fundamentals for Post-beginners by Jorg Hickl

     If you want to improve at chess, you must know the characteristics of typical P-formations and understanding them is the focus of GM Jorg Hickl's latest (published this year) book. 
     Better than Hans Kmoch's masterpiece, Pawn Power in Chess, Hickl's book is targets the average player and gives examples of hanging pawns, isolated pawns, backward pawns, passed pawns, doubled pawns, weak squares and pawn chains. Like Pachman's classic, Modern Chess Strategy, Hickl also includes three chapters showing the strengths and weakness of Rooks, Knights and Bishops. Unlike Pachman though, he does not include the Queen and King. 
     This book is good for players in the 1500 to 1800 range. Or, it could also be used by those under 1500 if they are willing to put in some effort and those over 1800 if they want to review what they should already know.

Chess Developments: The Sicilian Dragon by IM David Vigorito

     Vigorito gives good, but limited coverage of Dragon theory and as with all books that present the 'latest' theory they are soon outdated and this book was published back in 2011. In order to stay current you will need additional resources...at least if you are rated 2000 or better. For players below that a good over view of the most popular lines should suffice, so it has value for players below 2000 in that it will give them a place to start whether they might face the Dragon or play it as black. At least the 'theory' is not twenty or thirty years old.
     Because there's so much theory on the Dragon, this book only covers 9. Bc4 and 9. 0-0-0 with g4, but it does so very thoroughly. No Levenfish (6.f4), Classical (6.Be2) or Fianchetto variations (6.g3) and no ...Qa5 lines by black against the Yugoslav Attack, for example.
     Instead he has concentrated on the Soltis Variation, the Modern Variation, the Topalov Variation, the Chinese Variation and the Accelerated Variation when white plays 9.Bc4. If white plays 9.0-0-0 he covers black replies 9...d5 and 9...Nxd4.
     The book is nicely laid out...major variations are in bold-face and evaluations and plans explain why certain moves are good or bad, sort of in the style of the Dummy books.

Alekhine: Move by Move

     

Another book on Alekhine's games? What's the need for one?  This one is different. FM Steve Giddins looks at his favorite Alekhine games and challenges the reader to answer questions designed to keep you involved and allow you to monitor your progress. Giddins points out that while studying the classics may not be fashionable with modern day GMs, doing so is both enjoyable and instructional for us ordinary players. 
     Giddens analyzed 35 of Alekhine’s games and twenty positions. He uses mostly words and not a lot of concrete analysis in explaining Alekhine’s moves which makes it great for the lower-rated player. He relied on an old engine (Fritz 12) to check his lines, but because he is explaining plans and ideas in words for average players, a correction here or there that a stronger engine may have found is not a big issue as far as I am concerned. If I want a lot of analytical lines I will do the same as always...play over the games with my own engine. 
     One reviewer didn't like the book because he thought that because Giddins is only an FM he is not capable of explaining Alekhine's games.  That's just plain asinine. As an FM Giddins is 1) strong enough to understand what went on in the games, even if it's only AFTER the fact because he has seen the outcome and knows what Alekhine had in mind, 2) he has access to engines which point out tactical flaws, 3) he has access to tablebases for aid in researching endings and 4) he has access to the notes of many other, stronger players. If you went by this fellow's criteria a lot of great chess books would have to get thrown out and we'd be left with only a handful of books written by world class GMs. 
     Giddins has used a minimum number of Alekhine's best known games, but of course there are some that just had to be included in this collection. And, of those that are included, thanks to the use of a chess engine, he has been able to shed new light on them. He also did not include any games against Capablanca because Kasparov included some of them in My Great Predecessors. Also, there's no autobiographical material, but like his games, a lot has been written about Alekhine and apparently Giddens saw no reason to repeat it and drive up the price of the book.

A Must Have Database

     One of the most important databases you can have is MegaBase. It has over 6.46 million games. The database is searchable by player, tournament, and annotator and you can access various keys for openings, endgames, strategic and tactical themes. Also included are annotated games and a year’s worth of weekly updates and PlayerBase (this requires ChessBase 12 or 13), which collects rating data and pictures for thousands of players if you are interested in using that feature. The 2016 version includes over 68,000 annotated games. Many of them are Super-GM games annotated by other GMs, but there are also a lot of games annotated by IMs John Donaldson and Elliot Winslow which come from come from tournaments played at the Mechanics Institute in San Francisco. 
     One important feature is the update service that allows you access to weekly downloads of 5,000 games; this service is available for one year. Everybody knows of the enormous opening preparation that GMs and top-level correspondence players have to do. Back before computers the pros lugged around books and their own personal notebooks and index cards while correspondence players, in addition to opening books, subscribed to all the foreign magazines they could find. These days a monster database is essential. 
     Of course, readers of this Blog aren't likely to be playing in any international tournaments and won't likely be playing any GMs soon, so why should you buy this product and what can you do with it? How do you get the most out of your database? 
     With a databases you can review statistics on specific opening line, the percentage of the time a move has been played, how ell did it fare, when was it last played and what was its performance rating. You can locate games based on any criteria you want. All that's interesting and can be important if you are a serious correspondence player, but most of us aren't and my experience has been that class players usually leave the book within a handful of moves anyway, so memorizing lines 20 moves deep (assuming you have the ability to do even that) is a waste of time. A good opening book that explains the reasons behind the moves is a better investment. 
     Even if you can't remember line upon line of analysis it is very useful to be able to play over a lot of games using your opening lines so that PATTERNS become familiar and databases are great for that. 
     One thing you do have to remember is that a database only tells you which moves been played in the past by humans and those moves may be flawed and the refutation may or may not have been found.  
     Also, rememebr the sample size may be far too small too draw any conclusions. Another issue is when was the move last played? The older the game, the less likely the opening is to be considered good by modern standards. Case in point, in my early years Reshevsky was my favorite payers and I admired the ease in which he won games using the Exchange Variation against the Queen;s Gambit Declines and then proceeded to carry out the Minority Attack and racked up easy wins. Throw in Pachman's treatment in Modern Chess Strategy and Botvinnk writings on it, and it seemed like a great way to score points. Didn't work. Modern players were just too well versed in how to handle it, so I got a lot of draws. 
     Also, remember that a line might score heavily, but a recent development refutes it. I once made an opening book consisting of recent games played by correspondence players rated over 2500. They players were not only highly rated, but it was almost certain that their moves were checked by engines, so what could go wrong? In one game the opening line was from a game that was 3 or 4 years old and somewhere around move 20 I noticed my engine was suggesting a major improvement that left me at a serious disadvantage. Of course my opponent played it. 
     It is also important to consider the strength of the players in your assessment. Lines popular on lower levels may not work when played against higher rated opponents. You also need to consider whose games are in the database because games by near beginners are sometimes included. The best advice when using any database is...CHECK EVERYTHING.

Fritz 14 with Deep Fritz 64-bit [Download]

After reading customer reviews of this program I am convinced that most are NOT fair! I have used Fritz for years and have had absolutely NO PROBLEMS with it. In fact, it is still my go-to program because of its versatility and ease of use. This is a great chess program. Many users complained that it is complicated, but it appears most of them are former Chessmaster users who are not serious players or else their computer literacy is very, very poor. Download it and install Stockfish 7 or purchase and install Komodo 10 (or both) and you will have a top notch analysis program and database, plus many other valuable features...and maybe a few that are less so. And...the price is reasonable.

Must Have Books for Novices

Logical Chess Move by Move by Chernev. This classic explains 33 complete games in detail and explains the reason for every single move.

 

Silman's Complete Endgame Course. Good! Silman separates endgame knowledge into rating level... Unrated-999, 1000-1199 and 1200-1399. Even if you are rated higher than 1400 it's still good to review this material.

Simple Chess by Michael Stean. Introduction to strategy aimed at novice players, but also excellent for intermediates! 

 

Chess Structures: A Grandmaster Guide by Mauricio Flores Rios

    

    I have not had the opportunity to review any chess books in a while simply because I haven't bought any, but recently was intrigued with this book after browsing through it.

     There have been several books that cover P-structures, Pawn Structure Chess by Andy Soltis for example and the monster work on the isolated QP by Alex Baburin, Winning Pawn Structures. That last one turned out to be more work than I cared to put in! 
     What I liked about Rios’ massive 464-page book is that it's a collection of 140 games (and positions) divided by P-structure. Flores Rios, like authors before him, takes a pretty classical approach by breaking down P-structures into families. He covers: 
A) 1.d4 d5
B) Open Sicilian 
C) Benoni 
D) King's Indian 
F) French 

     Each structure is further sub-divided by theme. Example: the d-Pawn opening chapter covers isolated pawn, hanging pawns, the Carlsbad formation, the Caro-Kann formation, the Slav formation, Stonewall formation, and Gruenfeld. 
     Best...he includes annotated games as examples that illustrate the objectives and then he gives final remarks. As one commentator opined, this book is not a primer of positional play, but rather the author describes the interrelation between P-structure and how you should go about planning. 
    Well written and I am happy to see somebody writing about something other than tactics! Recommended.
