Pre Move Checklist:
1. Make sure all your pieces are safe.
2. Look for forcing move: Checks, captures, threats. You want to look at ALL forcing moves (even the bad ones) this will force you look at, and see the entire board.
3. If there are no forcing moves, you then want to remove any of your opponent’s pieces from your side of the board.
4. If your opponent doesn’t have any of his pieces on your side of the board, then you want to improve the position of your least active piece.
5. After each move by your opponent, ask yourself: "What is my opponent trying to do?"
Middlegame Planning:
1. Expand your position:
a. Gain more space.
b. Improve the position of your pieces.
2. Decide on what side of the board to play.
a. Queenside: a-c files.
b. Center: d-e files.
c. Kingside: f-h files.
Compare, space, material, and weakness(es)
Play where you have the advantage.
3. DO NOT HURRY. Regroup your pieces, and be patient.
