Bishop Development Tutorial



1.
[{F:W}{B:rnbqkbnr/pppppppp/32/PPPPPPPP/RNBQKBNR}{W:003_295}{W:sil}{W:003_296}This chapter will focus on using pawn skeletons to determine the way to develop the Bishop. The most important principle about Bishops is that they are long range pieces. They hate to be locked into closed positions. Like Rooks, Bishops operate best in open positions.]

2.
[{B:8/pp3ppp/3p4/2pPp3/2P1P3/8/PP3PPP/8}{D:8700}{N:c4c5d5d6e4e5}{W:003_297}{W:sil}{W:003_298}Here we see a position from a Bishop's worst nightmare. The pawn skeleton shows a position which is totally blockaded. The center pawns are locked in place. For a Bishop to become effective in such positions, the players will have to create a few pawn exchanges.]

3.
[{C}{B:8/pp3ppp/3p4/2pPp3/2P1P3/8/PP3PPP/8}{W:003_299}Let me show you why closed positions are Bishops worst nightmares. Let's add a Bishop to each player's positions.{B:8/pp2bppp/3p4/2pPp3/2P1P3/3B4/PP3PPP/8}{D:2000}{N:d3e7}{W:sil}{W:003_300} This is a classic example of two bad Bishops. We say a Bishop is bad when its pawns are on the squares of the same color.]

[{C}{B:8/pp2bppp/3p4/2pPp3/2P1P3/3B4/PP3PPP/8}{D:1393}{H1:c4}{D:905}{H1:d5}{D:1172}{H1:e4}{D:2809}{A:Wd3c4}{A:Wd3e4}{W:003_301}In this case, White's c4, d5 and e4-pawns completely lock-in White's Bishop. It is reduced to a role of passive defender.]

5.
[{B:8/pp2bppp/3p4/2pPp3/2P1P3/3B4/PP3PPP/8}{C}{R}{D:3610}{H1:d6}{D:1033}{H1:c5}{D:1079}{H1:e5}{D:2461}{A:Be7d6}{W:003_302}Likewise for Black. His central structure of d6, c5 and e5-pawns neutralize his Bishop.{W:sil}{C}{R}{W:003_303} More than anything, the players of these armies would love to activate their Bishops to open diagonals.]

6.
[{B:8/pp2bppp/3p4/2pPp3/2P1P3/3B4/PP3PPP/8}{D:3250}{A:Wd3e2}{N1:e2}{D:2113}{A:We2g4}{N1:g4}{D:2368}{A:Wg4c8}{N1:c8}{W:003_304}In White's case, he would try to play 1.Be2, 2.Bg4 and 3.Bc8, turning his passive white-squared Bishop into a more active role.]

7.
[{B:8/pp2bppp/3p4/2pPp3/2P1P3/3B4/PP3PPP/8}{R}{C}{D:9218}{A:Be7g5}{N1:g5}{D:2252}{A:Bg5c1}{N1:c1}{W:003_305}{W:sil}{C}{R}{W:003_306}Black shouldn't hesitate either. He should also move his Bishop 'around' the blocked center onto an open diagonal by 1...Bg5 and 2...Bc1, activating his Bishop. As this example shows, for a Bishop to be effective it must have an open diagonal!]

8.
[{B:8/pp2bppp/3p4/2pPp3/2P1P3/3B4/PP3PPP/8}{W:003_307}{W:sil}{W:003_308}If you have a Bishop that is blocked in by its own pawns, what to do? The easiest solution is to exchange it for the opposing Bishop, or perhaps a Knight. Sometimes this isn't possible. The next try would be to move the pawns out of the Bishop's way.]

9.
[{B:2n5/pp3ppp/2p5/4p3/2P1P3/1P6/P3BPPP/8}{D:2300}{N:e2c8}{D:2000}{C}{D:4200}{N:a2b3c4e4e2}{W:003_309}{W:sil}{W:003_310}This diagram features a position of Bishop versus Knight. On the surface, it looks like a pretty bleak future for White's Bishop. His center and Queenside pawns are all on white squares, the same color as the Bishop.]

10.
[{B:2n5/pp3ppp/2p5/4p3/2P1P3/1P6/P3BPPP/8}{C}{D:7400}{S:c4c5}{W:003_311}However, the pawns are not locked. White can still mobilize his pawns. He begins by 1.c5!]

11.
[{B:2n5/pp3ppp/2p5/2P1p3/4P3/1P6/P3BPPP/8}{D:4922}{A:Bc8d6}{D:3529}{A:Bd6e4}{N1:e4}{W:003_313}A very good move. Black's Knight is prevented from playing ...Nc8-d6 with an attack against the e4-pawn.]

12.
[{B:2n5/pp3ppp/2p5/2P1p3/4P3/1P6/P3BPPP/8}{R}{C}{D:4700}{S:c8e7}{D:2300}{S:e2c4}{D:2000}{A:Wc4f7}{W:003_314}{W:sil}{W:003_315}{W:sil}{W:003_316}More importantly, the Bishop is given new life: 1...Ne7 2.Bc4. White's Bishop is now bearing down on the f7-pawn.]

13.
[{B:8/pp2nppp/2p5/2P1p3/2B1P3/1P6/P4PPP/8}{R}{D:737}{S:f7f6}{D:2664}{S:c4e6}{W:003_317}2...f6 3.Be6]

14.
[{B:8/pp2n1pp/2p1Bp2/2P1p3/4P3/1P6/P4PPP/8}{D:6600}{A:Be7g6}{D:2300}{A:We6c8}{D:2600}{N:b7}{W:003_318}{W:sil}{W:003_319}In the space of just a few moves, the Bishop has become a powerful piece. Should Black's Knight move, then the idea of Be6-c8 attacking the b7-pawn will be possible. We began with a position that looked terrible for White's Bishop. But, as it was his move, we allowed him to improve his Bishop at once with the move 1.c5!]

15.
[{B:2n5/pp3ppp/2p5/4p3/2P1P3/1P6/P3BPPP/8}{D:12900}{S:c8d6}{D:1600}{A:Bd6e4}{W:003_320}What if we go back to the example and give Black the first move? If it were Black's move, he would try to ensure that the pawn structure was locked up and that White's Bishop was encased. He'd play 1...Nd6, attacking the e4-pawn.]

16.
[{B:8/pp3ppp/2pn4/4p3/2P1P3/1P6/P3BPPP/8}{R}{D:1700}{S:f2f3}{D:792}{W:sil}{S:c6c5}{W:003_323}And after 2.f3 c5! White would have a truly miserable position.]

17.
[{B:8/pp3ppp/3n4/2p1p3/2P1P3/1P3P2/P3B1PP/8}{W:003_326}{W:sil}{W:003_327}{W:sil}{W:003_328}{W:sil}{W:003_329}Because Bishops are long range pieces that can attack from afar, they are beloved by aggressive players. They do, however, have some pretty serious drawbacks. The most obvious one is the fact that they can only move around to half the squares on the chessboard. While this drawback may not trouble the Bishop, it can cause you and me a lot of agony. Imagine yourself as the player in the next diagram.]

18.
[{F:W}{B:7k/32/3B4/7P/6K1}{W:003_330}You have to be pretty pleased with yourself that you've reached such a position. You are a Bishop and pawn to the good and you have been expecting your opponent to stretch his hand in congratulations.{W:sil}{W:003_331} Surprisingly, this hasn't happened yet. Slightly annoyed, you now decide that it is time to force your extra pawn up the board to promotion and checkmate the Black King. {W:sil}{W:003_332} Much to your befuddlement, this position is a dead draw!]

19.
[{B:7k/32/3B4/7P/6K1}{D:7250}{S:h8g8}{D:800}{S:g8h8}{D:2800}{S:h8g7}{D:900}{S:g7h8}{W:003_333}Black's defense is to keep his King in the corner, moving it back and forth either by ...Kh8-g8-h8 or ...Kh8-g7-h8.]

20.
[{B:7k/32/3B4/7P/6K1}{D:3000}{A:Wh2h8}{A:Wd3h7}{W:003_334}White can't force Black out of the corner, because the light-squared Bishop doesn't control the queening square.]

21.
[{B:7k/32/3B4/7P/6K1}{R}{W:003_335}This rotten piece of luck happens to everyone. With any other pawn the King can be forced out the other side and the White King can escort the pawn home. But with the a- or h-pawn, the stalemate theme shows up and, in order to win, the Bishop must control the promotion square.{W:sil}{W:003_336}{W:sil}{W:003_337} The Bishop can only control half the squares on the chessboard. This fact should not be forgotten!]

22.
[{B:2q3k1/p6p/2p2bp1/2P5/1P2B3/6P1/4QP1P/6K1}{W:003_338}{W:sil}{D:8700}{N:a7}{D:1000}{H:c6}{D:3000}{C}{D:5800}{N:b4c5f2g3h2}{D:2000}{N:a7c6g6h7}{W:003_339}{W:sil}{W:003_340}Like Rooks, it is possible to create a battery with a Bishop. This example features an open position with a split pawn structure. Black has split Queenside pawns. His a7 and c6-pawns are disconnected by a file. This means that they cannot protect each other, making them vulnerable. White has two pawn islands, while Black has three.]

23.
[{B:2q3k1/p6p/2p2bp1/2P5/1P2B3/6P1/4QP1P/6K1}{D:3000}{A:We4c6}{W:003_341}Black's split pawns are vulnerable. In fact, White's Bishop is greedily eyeing the little c6-morsel. All White has to do to win the c6-pawn is to reinforce the pressure against it. White plays Qf3, creating a battery along the h1-a8 diagonal. Coincidentally, White's Queen also attacks Black's Bishop.{R}{W:sil}{D:750}{S:e2f3}{D:2000}{A:Wf3c6}{D:5000}{A:Wf3f6}{W:003_342}]

24.
[{B:2q3k1/p6p/2p2bp1/2P5/1P2B3/5QP1/5P1P/6K1}{R}{N:e4f6}{D:3000}{C}{D:15000}{A:Bf6c6}{W:003_343}W:sil}{W:003_344}{W:sil}{W:003_345}The diagram also features a common occurrence known as Bishops of opposite colors. Positions with Bishops of opposite colors favor the attacker. The reason is the defender won't be able to use his Bishop to block the attack, as is the case here. Black cannot defend his c6-pawn with his Bishop.]

25.
[{B:2q3k1/p6p/2p2bp1/2P5/1P2B3/5QP1/5P1P/6K1}{R}{C}{W:003_346}While Bishops of opposite colors favor the player with the attack, such positions can also make a defender rather happy.]

26.
[{B:16/3kB3/3Pb3/4P3/3K4/16}{D:16000}{N:a1b2c3d4e5f6g7h8}{W:003_347}Here White has a sizable material advantage. He is two connected passed pawns up. But the presence of the Bishops of opposite colors makes the situation a dead draw. Black will happily move his Bishop on the long diagonal a1-h8. White cannot make further progess.]

27.
[{C}{W:003_349}Essentially, Bishops of opposite colors allow the players to be the masters of the squares on which their Bishops operate.]

28.
[{W:003_350}{W:sil}{W:003_351}The outcome of this game would change if the Bishops were of the same colors. Take out a chess board and play it out with the Bishop on e6 changed to a Bishop on e3. In no time, you should be able to force White's connected passed pawns up the board.]

29.
[{W:003_352}Earlier, we looked at a battery of Queen and Bishop. Such batteries come in many varieties. The most often seen are the following two examples.]

30.
[{B:3q2k1/p4ppp/1pn5/3p4/8/P2BP3/1P3PPP/3Q2K1}{D:4632}{S:d1c2}{W:003_353}Here, White takes advantage of a tactical double threat to play 1.Qc2.]

31.
[{B:3q2k1/p4ppp/1pn5/3p4/8/P2BP3/1PQ2PPP/6K1}{A:Wc2c6}{D:4600}{R}{N:b1c2d3e4f5g6h7}{W:003_354}Attacking the exposed c6-Knight and by making a battery on the b1-h7 diagonal, Black has to choose whether to lose his Knight or the h7-pawn.]

32.
[{B:3q2k1/p4ppp/1pn5/3p4/8/P2BP3/1P3PPP/3Q2K1}{D:6896}{S:d3h7}{D:2507}{S:g8h7}{D:2600}{S:d1c2}{W:003_355}Before leaving the diagram, two points should be noted. White could also have started with 1.Bxh7+ Kxh7 2.Qc2+, which recovers the piece and wins a pawn.]

33.
[{B:3q4/p4ppk/1pn5/3p4/8/P3P3/1PQ2PPP/6K1}{D:4500}{N:d5}{D:4000}{C}{W:003_356}The other point is, did you notice Black's pawn structure? Black's d5-pawn is called an ISOLATED PAWN. This refers to the fact that the pawn cannot be protected by another pawn.]

34.
[{B:6k1/pp1q1ppp/8/3p4/8/P3P3/1PB2PPP/3Q2K1}{W:003_358}In this example, White creates a battery by putting his Queen in front of his Bishop, {D:700}{S:d1d3}{W:sil}{W:003_359}1.Qd3!]

35.
[{B:6k1/pp1q1ppp/8/3p4/8/P2QP3/1PB2PPP/6K1}{D:1100}{A:Wd3h7}{D:6000}{R}{A:Bg7g6}{D:2400}{R}{A:Bf7f5}{W:003_360}White threatens Qd3xh7+ and Black is forced to play either 1...g6 or 1...f5. This battery that White has created doesn't win material, but does force Black to move a pawn, which creates some weak squares.]

36.
[{B:6k1/pp1q1ppp/8/3p4/8/P2QP3/1PB2PPP/6K1}{W:003_361}For example, suppose after 1.Qd3, Black chooses{D:700}{S:f7f5}{W:sil}{W:003_362} 1...f5]

37.
[{B:6k1/pp1q2pp/8/3p1p2/8/P2QP3/1PB2PPP/6K1}{D:2200}{N:e5}{W:003_363}The result is that Black has weakened the e5-square. White could play{W:sil}{C}{D:700}{S:d3c3}{W:003_364}2.Qc3 {W:sil}{W:003_365}and try to occupy the e5-square, because no Black pawn can protect that square.]

38.
[{B:6k1/pp1q1ppp/8/3p4/8/P1Q1P3/1PB2PPP/6K1}{S:c3d3}{D:1000}{S:g7g6}{W:003_366}What about 1...g6? In that case, the pawn's move has weakened the f6-square. {W:sil}{D:1500}{S:d3c3}{W:003_367} White could use the same move 2.Qc3 and try to occupy the f6-square.]

39.
[{W:003_368}This combination of understanding the pawn structure with piece play, such as creating a battery, is what planning is all about.]

40.
[{W:003_369}Because a Bishop is a long range piece, it stands to reason that, as the game opens up, its value as a member in our army increases. Perhaps in the opening and early middlegame, our Bishops didn't always find the right diagonals. {W:sil}{W:003_370}Not so in the ending. As pawns are exchanged, the Bishops have an easier time taking part in our plans. This principle of the Bishops reaching their potential is best seen in the ending where the position is so open.]

41.
[{B:3n4/16/3B4/32}{W:003_371}One thing a Bishop can do very well is to dominate a Knight.{W:sil}{W:003_372} This is a classic example.]

42.
[{B:3n4/16/3B4/32}{A:Bd8b7}{H1:b7}{A:Bd8c6}{H1:c6}{A:Bd8e6}{H1:e6}{A:Bd8f7}{H1:f7}{D:3000}{R}{A:Wd5b7}{A:Wd5f7}{W:003_373}Note how the Black Knight is solidly rooted to its square. Without protection it cannot move.]

43.
[{B:64}{W:003_374}Let's test the knowledge we have learned by following a game from the big leagues.]

44.
[{B:8/2k1n3/1p4p1/pKp2p1p/P4P1P/2P2BP1/1P6/8}{W:003_375}In this game we will see how Bobby Fischer, playing White, methodically uses his Bishop to make inroads on Mark Taimanov's position.]

45.
[{B:8/2k1n3/1p4p1/pKp2p1p/P4P1P/2P2BP1/1P6/8}{D:700}{S:b5a6}{W:003_376}1.Ka6! {W:sil}{W:003_377} This move forces Black to move his Knight, because any King or pawn move would cost material.]

46.
[{B:8/2k1n3/Kp4p1/p1p2p1p/P4P1P/2P2BP1/1P6/8}{D:487}{S:e7g8}{D:2240}{S:f3d5}{D:1381}{S:g8e7}{D:2391}{S:d5c4}{W:003_378}1...Ng8 2.Bd5 Ne7 3.Bc4!]

47.
[{B:8/2k1n3/Kp4p1/p1p2p1p/P1B2P1P/2P3P1/1P6/8}{W:003_379}A subtle move that will soon become clear. White wants to achieve a position where it will be Black to move. So, he deliberately makes a waiting move, in order to force his opponent to move. This loss of a move is called losing a tempo.]

48.
[{B:8/2k1n3/Kp4p1/p1p2p1p/P1B2P1P/2P3P1/1P6/8}{D:534}{S:c7c6}{D:2194}{S:c4f7}{D:1497}{S:c6c7}{D:2078}{S:f7e8}{W:003_380}3...Kc6 4.Bf7 Kc7 5.Be8 {W:sil}{W:003_381}White has created the maximum position possible.]

His Knight is chained to the defense of the g6-pawn base. If this pawn goes, the whole Kingside structure collapses. The King is also tied to the defense of the b6-base pawn.]

[{B:1k6/8/1PK5/P4p1p/4nP1P/6P1/16}{W:003_391}If a lone Bishop in the ending can be so powerful, it stands to reason that two Bishops working side by side can do major damage.]
