all you say is fine. in addition, I like to stop at key positions and ask myself if I not only understand the GM's strategy, but also if I would feel confident playing his/her moves........as I would like to say, if presented with certain positions, I would play like the GM. I have never done this with Tal-type sacrifices, but have been successful with other famous players, ie; Botvinnik, Alekhine, Fischer........
many great biographies out there. they are some of the best books to learn from, ie; famous players sharing their thoughts on their games......
Please share the method that works best for you.
I would like feedback on ways to improve the way I study GM games. The method I use is this:
1. Find collection of well annotated GM games of early masters (Morphy, Steinitz, etc...) such as "Masters of the Chessboard" by Reti.
2. Play over the games with a real board.
3. Try to guess the move that the Master played and analyze why my move is or isn't the right one.
4. Go through all variations given and any moves that I would play or I'm curious about until I understand them to the best of my ability.
5. Note the moves that I got wrong with a hypothetical reason why and any new ideas I got from the game.
I would say on average that this takes me 2 hours/game. I haven't noticed an ability for me to retain anything noticeable about pawn structures (despite making a few deliberate efforts in this regard) by doing this and I kind of think that my best bet would be to study them separately to get a "foothold" per se on the ideas and by doing so I would be able to notice when those ideas are applied and make for a more productive experience in that regard. All in all, it seems that the main thing that I get from my study method is an increased imagination and a few ideas on how to adapt my thinking in a way to allow more logical chess. I think that I could get more out of these games if I tweaked my study patterns a bit but I'm not sure what parts it is missing and I would appreciate any insight on this matter. Thank you for your time.
