Last night I had a lesson from my IM chess coach. He described what he called 'power moves,' which as the name suggests are powerful moves that should be considered in order of most powerful to least powerful when calculating, and in this way you will organize your thoughts efficiently. The power moves are:
1. The Double Check. This is the most powerful power move because it forces the enemy king to move. Both attacking pieces can be hanging, yet the king must move because both threats cannot be countered through any other means (interposition, capture, etc.)
2. Check. Checks cannot be ignored, they must be honored which makes a powerful forcing move. The capacity to check can grind to a halt your opponents combination and flow if they allow it.
3. Taking a Piece. Taking material from your opponent puts pressure on them. At some point they must try to equalize by taking material back, though not necessarily right away.
4. Threatening Mate. Mate threats must, of course, be countered. The best way to counter a mate threat is to dissolve the threat while simultaneously creating your own threats, perhaps by attacking another piece.
5. Threatening a Piece. The threat to capture a piece weighs heavy in your opponents consideration. Threatening pieces will make your opponent defend them or reposition, and this may potentially create weaknesses in the enemy camp, particularly in pawn structure.
Last but not least the concept of LPDO. Loose Pieces Drop Off!
What do you guys think, would you re-order anything, add anything, ammend?
