It's not necessary to memorize the positions. Instead it's important to make decisions, and determine whether your decisions were better or worse than the "correct" decision (move played by GM in master games or computer in yours), not to mention WHY.
Memorizing the position will help you in that exact position- figuring out the defects in your thinking will help you in many.
Hey guys.
I would be interested in your feedback. Whether it be master games or your own games, is it more efficient to memorize the full game itself, or specific positions (the critical moments)?
My idea is that while you are more immersed in the struggle trying to recite each and every move, you might go over more games by simply running through positions and remembering them.
Anyway, I don't think there is a right or wrong answer... feel free to share your thoughts.
