An ABC of chess

Exeter Chess Club: An ABC of Chess

Here's a mental toolkit for the improving chess player.

  I think that for each of these elements there are different levels of understanding e.g. bad Bishop

1) I've heard of it!

2) I know what it is and could explain it to a junior.

3) I understand enough to make use of the idea in a game.

4) I never fail to notice the feature in a game, and rarely (if ever) make a bad choice of plan based on it.

  I suspect we're all OK at (1) but aren't all at (4) yet. (3) is a fair goal.

-------------------

(Rubinstein-Schlechter, San Sebastian 1912): White's active pieces give him the advantage.

B - better pieces - bad bishop bishop vs knight, offside piece, coordination

"Quality, not quantity"

(Georgadze-Kupreichik, 1979)An extraordinary piece of centralisation: despite the exchange less, and the King's-side attack, White soon won.

-------------------

(Deep Blue-Kasparov, m1 1996): just hideous: every Black Pawn is isolated and most doubled! Black tried a King's-side hack but it was desparation and he knew it.

H - holes and weak complexes

"Perils of both wind and limb" - Butler

This is a list long enough to get you started comfortably. There are a few other ideas, like "coordination", which you may come to later, and through Nimzovitch we learn about themes like "overprotection" and "prophylaxis".
