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 it does play at the Grandmaster level, but 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.
