1. Centralize the Queen
2. Don't put the King in front of the Pawn
3. Put the King in the neighborhood vertical/horizontal to the opponent King
4. To defend effectively, put the King to the opposite corner of the board where the opponent's pawn promotes (if the pawn is a knight or rook pawn; with the bishop and central pawns you can save your position only if your king is in front of the pawn, stopping it).
5. King goes toward King to meet checks with counter-checks
