Chess Players
Pattern, geometry, and the move you found because you saw it once before.
Chess strength is mostly pattern recognition stored in long-term memory. The games below all train the bits that complement openings and endgames · pure tactics, pure rotation, pure rule-induction.

Why these games
Chess Mate is forced-mate-in-one drilled explicitly. Spatial Rotation is the board-geometry primer behind every visualisation. Matrix Reasoning is the rule-induction skill applied to positional structures.
