Concentric Squares (forks and skewers):
- Place black king on d5 and black rook on d4, then sequentially place white queen on every square where it forks or skewers the rook and king
- Move rook in square around king (e4, e5, e6, d6, c6, c5, c4,) and repeat exercise with queen for each position.
- Move rook one square further away from the king and repeat exercise.
- Keep moving rook in larger squares until it reaches the edge of the board.
- Repeat exercise with black knight, bishop and queen.
- Repeat exercise with white knight, bishop and rook.
- Repeat exercise with king starting on a different square (e.g. g8 or c8)
Knight Vision I
- Place knight on a1 and touch all squares it can move to.
- Move to a2 and repeat.
- Continue moving knight up a-file, down b-file, etc. repeating the exercise for every square on the board.
Knight Vision II
- Place knight on d5 and calculate shortest path for it to reach d4.
- From d5 calculate shortest path for every square around d4.
- Calculate shortest path squares one square further away.
- Repeat exercise as in concentric squares until reaching the edge of the board.
- Repeat exercise with knight starting on a different square (e.g. c3, f3, c6, f6).
Michael de la Maza emphasizes physically moving the pieces on the board for the concentric squares drill and physically touching the squares on the board for the knight vision drills. That sounds good to me, but I'd think it'd be good to do all three: physically interacting with a board and pieces, moving pieces and highlighting squares on a computer, and doing the exercises blindfolded.400 Points in 400 days
