There's quite a few thing psychology discovered about chess player worth knowing:

1. Chess players have a highly efficient mode of (high-level) perception. They can access the key elements of a position rapidly.

2. Chess players show a remarkable memory for chess positions and games. This ability typically does not extend beyond chess.

3. Chess knowledge is encoded at several levels, in particular at a low, perceptual level, where patterns of pieces are stored, and at a high, conceptual level, where information about plans, evaluation, etc., is stored. These various types of encoding, with rich indexing and a high level of cross-referencing, account for chess players’ excellent professional memory.

4. Chess players search highly selectively. It is rare that they analyze more than one hundred positions in the search tree before choosing a move.

5. There is no difference between the search algorithm of class A players (Elo 1800-2000) and that of Grandmasters.

6. Masters lose relatively little of their skill when they play simultaneous games or speed chess.
