i strongly agree with the usefulness of that analysis, however if the computer makes weaker moves then you don't get the same depth and reason as to why that move you or your opponent made was wrong. Imagine as to the reason why people wish to get coaching from GM's as opposed to someone rated 300-500 points higher. after all the difficulty with GM moves is finding them. with the computer it shows extremely deep analysis often more than 10 moves deep which more often than not clearly reveals the intention of that move as opposed to the on you made. If you do wish for a weaker analysis for some reason, (matter of opinion i suppose) then i suggest getting a chess program which allows you to select the strength of the analysis although i cannot imagine where you will find such a program. This is clearly because we wish to make GM moves as opposed to FM or IM moves. I hope you do not take any offence to my opinion. Maybe i helped you think about the reason that they give GM moves though. hopefully i did otherwise this was quite meaningless.
Wish you the best.
Computer Analysis is a great feature. I analyze nearly every game, and it is my primary method of improving my chess skill. Behind supporting the site, it is the reason I pay for chess.com; play then analyze. I think I might benefit more from a “weaker” analysis from the computer.
I do not doubt that the 2500 strength “best move” is indeed the best move for a Master. However, I, and the majority of my opponents, are rated 700-1000 points lower than the 2500 analysis strength. The suggested corrections to my (and opponent’s) play are based on making Master moves, which is unrealistic.
I believe lower rated players would benefit from a weaker computer analysis; perhaps selectable increments so the student can choose. In this way, the best move will be closer to the player’s ability to perceive, and enable a real improvement in skill.
