Themes

Each number is a game; it opens the move where he explains the idea. Open a theme to read what it is about.

General

1. Make one move do two jobs

   When a task can be done in a way that also does something else, do it that way. Do not tie a piece to one job if another can do it and keep working.

Opening

1. Meet a flank move in the centre

   A pawn move on the wing does not develop anything. The usual answer is a strike in the centre.

Pawn structure

1. A pawn move leaves a hole you cannot fill

   A pawn cannot move backwards. Before advancing it, ask which square it stops guarding for good.

2. Attack a chain where it hurts - usually the base

   Attack a pawn chain at its base, unless the aim is to get rid of a particular pawn.

Strategy

1. Compensation is a list, not a feeling

   When you are a pawn down for compensation, list what you have in return and give each item a plan.

Tactics

1. A piece on the king's line is a tactic waiting

   A piece on the same line as its king can be pinned or hit by a discovered attack. Check those lines every move.
