The Baker Defense is a chess opening .

After the moves 1. e2 – e4 a7 – a6 ?! (in English called St. George Defense or Baker Defense ) the result is a very seldom played defense, the aim of which is to build up with 2.… b7 – b5 and then fianchette the queen bishop . The move Randbauer a7 – a6 follows similar ideas as the Sokolski opening (1. b2 – b4). However, since the black player loses a pace after this move compared to the white player, who also has the draw advantage , and takes the chance to achieve immediate counterplay in the center, this defense is therefore very rarely played and has hardly been researched.

This black opening election of the English grandmaster Tony Miles in his game against the then world champion Anatoly Karpov caused a stir in 1980 . Miles won after an inaccuracy by the Russian in the middlegame .

history

The first known game was a simultaneous game between the English amateur J. Baker and the first world chess champion Wilhelm Steinitz on December 11, 1868. The game was won by Baker. Probably the best-known use of defense was in Skara in 1980, when Miles defeated then world champion Anatoly Karpov . Since then, the defense has also been known as the " Birmingham Defense " - the name of Miles' hometown.

Even Boris Spassky played this defense, in the 22nd game of the World Chess Championship 1966 against the world champion Tigran Petrosian . The game began with 1. d4 b5 ( Polish Defense ), but became a Baker Defense by moving 2. e4 Bb7 3. f3 a6. It was a very poor use of this defense: Petrosian won the game, which gave him the 12 points needed to keep the title.

theory

The St. George defense is generally seen as a weak answer to 1. e4 - compared to 1.… e5, 1.… e6, 1.… c5 or 1.… c6. But it is also seen as weaker compared to the Owen defense (1. e4 b6 2. d4 Bb7) because Black only uses three moves for the development of his queen bishop; the Owen defense only needs two for this, while White is given the opportunity to occupy the center and would also be ready for castling .

The main line in this opening begins with 1. e4 a6 !? 2. d4 b5 and then branches out. The main line continues with 3. Nf3 Bb7 4. Bd3 e6 5. 0–0 Nf6. Another important variant is the “three pawn attack”, sometimes also referred to as the “Saint George's Gambit”, this continues with 3. c4 e6 !? 4. cxb5 axb5 5. Bxb5 Bb7.

Saint George is sometimes used to prevent the white bishop from occupying b5 in order to continue as in the French defense .

Michael Basman contributed largely to the theoretical processing of this variant .

variants

By move 2. Bf1 – c4 ?! White can set a trap , since Black cannot now with 2.… b7 – b5 ?? can continue without being disadvantaged. The runner sacrifice follows :

3. Bc4xf7 + Ke8xf7 4. Qd1 – h5 + g7 – g6 (after 4.… Kf7 – f6 follows 5. Qh5 – f5 mate ) 5. Qh5 – d5 + with winning the rook on a8. 4.… Kf7 – e6 is also not possible, since 5. Qh5 – d5 + Ke6 – f6 6. Qd5 – f5 mates.

On 2. Bf1 – c4 Black can, however, e7 – e6! reply that the bishop must move again after the following pawn advance b7 – b5 or d7 – d5.

In variants without an early Bc4, a move to Modern Defense with 2.… g7 – g6 and 3.… Bf8 – g7 is quite possible.
