These are the chess games that I am personally studying in an effort to become a chess master. I am selecting a limited number of games from various instructional sources.
In some sources I see advice that I agree with, which is simply to commit these games to memory. As daunting of a task that this sounds, it is possible to do, especially if we absorb a little bit at a time. It also takes much repetition, but that is the nature of memory.
Over time I will add analysis to some of these games, but it is not necessary to have analysis to start learning from these games. Human beings learn by example, and even if we don't fully understand the games, we can slowly pick up ideas.
