Same Color
Train your eye to instantly judge whether two squares share the same color. The two-square companion to the square color drill: it builds the parity sense that powers bishop play and spotting which squares sit on the same diagonal, all without looking at the board.
Pro tip: Two squares share a color when their files and ranks have the same parity. a1 and c3 are both dark; a1 and b2 differ.
