I have never tried the zip through 100 games in 30minutes approach except to study opening plans. However, I think the solitaire method can be effective at any strength, the key is which master games you are looking at IMO.
1000-1600 - Heavily annotated games of old masters. Capablanca, Alekhine, Morphy etc. Ignore openings, focus on opening development, tactics etc.
1600-1800 - Graduate to the 1940's-50's - Botvinnik, Bronstein's Zurich 1953 etc. Start to see the evolution to modern chess. Focus on pawn structure, strategy etc.
1800-2000 Fischer, Spassky, Tal etc.
2000+ Karpov, Kaspy, Kramnik etc.
3rd Topic of discussion on Chess.com/TV's "Pardon Our Blunders" with IMs Rensch and Pruess!
At what point in someone's "chess level/career" does it become useful to study the games of Grandmasters? And how should this study be conducted?
We both agreed that this type of work can almost NEVER be harmful or a waste of time, but at different levels -- it is probably more beneficial to study the games in different ways. Example:
At Expert to Master levels, it starts to make sense to apply the "Solitaire Chess" method, in which you would try to guess the moves of a Grandmaster BEFORE you see the whole game. Making an effort to REALLY apply yourself and insert your own thought process into the given position -- only to find out you were totally wrong about the plan chosen
.
However, at the beginning to intermediate levels, it makes a lot more sense to simply search and create a large list of games (perhaps on a specific topic -- ie an Opening, Pawn Structure, Type of Player, etc) and simply go over as many as you can -- NOT spending more than 45 secs- 1 and 1/2 minutes on ANY game. In this way, a player can, over time, begin to improve their intuition and "sub-conscious" approach to the game...
Watcha think?
