This was the main continuation from this opening, although it is now considered pretty played out. Black has a bad bishop on c8, so...

White has the better bishop, currently pointed at Black''s King's side, but this is only a temporary advantage. Left alone, Black can play ...Be6 or move the b-pawn and play ...Bb7. White's only hope of a win is to keep Black on the hop.

16. f5

Bad bishops

Bs move on squares of only one colour. A bishop hemmed in by its own pawns on the same colour squares is called a bad bishop. It is sometimes tempting to put pawns on the same colour squares as the bishop, particularly in the ending, with the hope that the bishop will defend them. Well, unfortunately, the bishop will probably be so blocked by the pawns that it can hardly defend itself. Depending on what other pieces there are on the board, the opponent's king will probably be able to slip in between the pawns, and the bishop won't be able to stop it. You want your pawns on one colour square, and the bishop on the other, in the middle game and in the ending. (And if you've got two bishops in the middle game, you generally want your pawns right out of the way.) So be careful where you put your pawns, and don't get your bishops stuck one side or the other of a chain of pawns.

The two bishops

"Deux fous gagnent toujours, mais trois fous, non!"
-- Alexander Alekhin, on the advantage of the Two Bishops at amateur level

  The bishop is a longer-range piece than the knight. This advantage is sometimes called the minor exchange, for, all else being equal, the bishop will be a better piece than the knight. Two bishops, provided they can make use of their better range and aren't blocked by pawns, are rather better than two knights or a knight and a bishop, particularly in fully open positions. (Think how easy it is to mate with the two bishops. Have you ever tried to mate with two knights?)


[EXERCISE:]

Capablanca advised rehearsing the mate with the two Bishops, not because it was particularly likely to occur in practice, but to experience directly the power of two Bishops cooperating in an open position.

  So in OPEN positions, the two bishops are boss.

  In CLOSED positions, the knights may be better.

  In SEMI-OPEN positions. well...

  The side with the two bishops must not let the knight(s) settle on any outposts, and can create trouble on both sides of the board at once when the poor knights will be hard-put to keep up. It's generally though that the two bishops are good enought to win. Paulsen made use of this in the middle 1800s, but the technique was perfected and publicised by Steinitz.

  Let's have a look at these in turn.


bishops: two bishops in ending

This was my introduction to the power of the two bishops.

Ditmas,H - Regis,D (March, 1979)

1. e4 e6 2. d4 d5 3. Nd2 c5 4. exd5 Qxd5 5. Ngf3 cxd4 6. Bc4 Qd6 7. O-O Nc6 8. Nb3 Nf6 9. Nbxd4 Nxd4 10. Nxd4 a6 11. b3 Qc7 12. Bb2 Bd6 13. h3 O-O 14. Bd3 e5 15. Nf5 e4 16. Nxd6

  White sensibly takes the two bishops.

Black must make a concession - in the event, I buried the bishop on g6. White's two bishops and queen's side majority win the game.

  It's worth dwelling on this for a moment. Material is equal, and Black can think about getting his own majority moving, but its all too late. The two bishops cover all the key squares, and Black can hardly stop the advance of the a-pawn.

 


bishops: two bishops in open middlegame

This is the other easy case: the bishops usually chop up the opposition.

Nunn - Tal (Wijk Ann Zee, 1982)

Here is an instructive moment from the Nunn/Griffiths book. White has many advantages, including an extra pawn.

25. Nf5!

"White is still in no hurry to exchange queens: he permits his opponent the option of 25...Bxf5 26 Qxf5 instead of the game continuation. EITHER WAY HIS BISHOP-PAIR WILL DOMINATE THE BOARD. But he is also returning the extra pawn: possibly as instructive a piece of Grandmaster thinking as anything that has gone previously. The point is not that the variations are difficult to calculate, but that Nunn is thinking boldly; dynamically. Time and again we see how his thinking is the reverse of a weaker player. It is not, 'If I play Nf5 I shall lose a pawn; I will only do that as a last resort'; but rather, 'I can simplify the position by Nf5 and continue to generate powerful threats; it would be a miracle if Black could get away with ...Rxc2"

25...Qxd5 26. Nxe7+ Rxe7 27. Bxd5 Rxe1 28. Rxe1 Rxc2 29. Re7

  It's all starting to clear up nicely.

29...Bc6 30. Bxf7+ Kf8 31. Rc7 hxg5 32. Bc5+ 1-0

 


bishops: two bishops in a semi-open or closed middlegame

This is not so easy. The side with the two bishops must open lines, but if it were easily possible, the Nimzo-Indian would not be a viable defence..

  Here are two fine examples where the Bishops win, one more open, one more closed.

Bronstein D - Golombek H (Moscow) [E43] 1956

Black is doing his best to get White to play d4-d5, when as well gaining the square c5, Black would expect the blocked pawn formation to favour the Knights. White finds an interesting way of resisting the encouragement.

  Normally in the Nimzo-Indian Defence, Black hopes to double the c-pawns to give a target for attack in the event that White disappears off to the King's side. Not here, so Black can only hope to gum up the game for his knights.

the two bishops in a semi-open endgame

And this is the hardest case, which Paulsen and Steinitz perfected. The side with the two bishops must deny the knights any stable outposts while advancing on both sides of the board.
