2.1 Good and Bad Bishops
A bishop is bad when many of its own pawns stand on squares of its colour, especially central pawns that are fixed. It bites on its own pawns and cannot reach the enemy position. A bishop is good when its pawns stand on the other colour and its diagonals are open.
Example 2.1 · The French bishop
The French Advance. Black's pawns on d5 and e6 stand on light squares, the same colour as the bishop on d7.
The bishop on d7 is Black's problem piece: the pawns on d5 and e6 block it. Black's plans in the French — the ...c5 and ...f6 breaks, ...♕b6 against d4, ...♘f5 — all aim to make up for this. A bad bishop is not a lost game, but it is a long-term weakness that shapes your plans.
2.2 The Knight on an Outpost
A knight is strongest on a central square deep in the enemy half where no enemy pawn can attack it. Such a square is called an outpost. A knight on an outpost often beats a bishop, especially a bad one.
Example 2.2 · The knight on d5
The Sveshnikov Sicilian. White has exchanged on f6 and put a knight on d5. No black pawn can attack it.
The knight on d5 is a monster: it controls c7, e7, f6 and b6, and Black cannot drive it away with a pawn. Black has the bishop pair as compensation and must play actively with ...f5. This is the typical trade-off: one side gets a great knight, the other gets the bishops and dynamic play.
Remember
- A bishop is bad when its own central pawns stand on its colour.
- An outpost is a square that no enemy pawn can attack.
- A knight on a central outpost is often stronger than a bishop.
- With a bad bishop, play pawn breaks or exchange the bishop.
