1. See a check give a check.
2. Resolve pawn tension (or any tension) immediately.
3. If a piece is forced to move and can capture a piece of equal value, it cannot retreat and must make that capture.
4. Moves that make immediate threats are always strong. Play them as if you get to move twice in a row i.e. without regard to opponent's response.
5. Captures must be answered by recaptures.
This seems to work:
1. Develop using sane, classical opening principles.
2. Castle early, and connect the rooks on the back rank.
3. In the middlegame, be mindful of sound tactical moves, whether coming from pattern recognition, study, or something you see as you study the board.
4. If no immediate tactics, continue to develop your pieces as efficiently as possible according to classical positional principles (maximizing space, rooks on open files, knights on outposts, bishops outside the pawn chain, etc)
5. Once you are a piece or a few pawns up, then trade down into a winning endgame.
Any thoughts?
