Pawn Majority on Queenside.

Pin It Botvinnik - Konstantinopolsky

Sverdlovsk 1943

Caro-Kann Defence

1 e4 c6 2 d4 d5 3 e x d5 c x d5 4 c4 Nf6 5 Nc3 Nc6
6 Bg5 e6 7 Nf3 Be7 * Rc2 0-0 9 c5 Ne4 10 Bxe7 Qxe7 11 Be2 Bd7 12 a3




The position reveals that white has the queenside majority against which Black’s knight at e4 is not sufficient compensation. Again White’s plan is to secure his pawn formation on the queenside, obtaining command of the square c6 and if possible c7 as well, then advance with b5 and c6 During these operations the e5- square acquires a special significance, for the knight posted there adds to White’scommand of c6.

After these remarks, the further course of the game is easy to understand

12 .... f5

The move has been criticesed because weakening e5 and thus playing into his opponent's hands. Correct was 12 .... f6 13 b4 Nxc3 14 Rxc3 a6 15 0-0 Rad8 to obtain counter play and a possible passed d-pawn as compensation for White's queenside majority.

13 Bb5

It is often essential to act quickly. The text move threatens 14 Bxc6 followed by 15 Ne5 and a gradual exploitation of his majority, as Black is practically powerless because of the solid position of White's Knight at e5

13 .... Ng5

This cuts across White's intention to occupy e5 with a knight, but at the cost of submitting to another drawback.

14 Bxc6 Nxf3 + 15 Qxf3 bxc6 16 Qf4 Rae8 17 0-0 e5 18 Qxe5 Qxe5 19 dxe5 Rxe5

The fight has assumed an entirely differently character. Certainly, White's pawn majority is still in being, but Black's protected passed d-pawn is no less valuable an asset. However, white has secured a fresh advantage ---- he has a good knight against Black's bad bishop. The bishop is bad because the black pawns stand on the same colour squares, and its mobility is thereby strictly limited. The knight is strong because sooner or later it will be able to reach d4, where it will be secure from both the enemy pawns and the bishop.
