Pawn Endings in Practice (2)

It’s been far too long since the first article in this series, but here’s a very instructive ending between two of Richmond Junior Club’s stronger members (both about 1500-1600 strength) on 22 March.

We start here, with White considering his 41st move. Should he trade rooks or not? First lesson: you have to calculate the pawn ending before trading the last pieces. So before you can play any ending well you have to understand pawn endings. In this case the pawn ending is won for Black, so White should avoid the trade. Although Black has a slight advantage I guess the rook ending should be drawn. We teach our pupils to move their king up into the centre of the board in the ending but here the correct plan for Black is to move his king to b4 to attack the c-pawn. This is an important position type, with the two immovable pawns on the c-file. Black can attack c4 from either b4 or b3, but Black can only defend from d3, so when he runs out of pawn moves on the other side he’ll have to capitulate.

Let’s see whether our gladiators were up to the challenge.

41. Rxb7+? (Now Black’s winning.) Kxb7
42. Kf1 Kb6
43. Ke2 Kc6? (Now it’s probably a draw. Ka5 followed by Kb4 is winning for Black.)
44. f4? (The computer gives 44. Ke4 as leading to a queen ending where White has a slight advantage.) f5? (Kb6, followed by Ka5 and Kb4 is winning again for Black.)
45. Kf3? (White can draw by moving onto the d-file. Now Black is winning again.) Kb6? (Good plan but poor timing. Black should have played h5, and then Kb6 etc.)
46. Ke3? (White can draw here by playing g4, when both players will promote.) Ka5 (Finally Black is on the winning track.)
47. Kd2 Kb4
48. Kd3 Kb3
49. g4 (Desperation) fxg4
50. g3 h5 (The last few moves have been fine for Black.)
51. f5 h4?? (All he had to do to win was play Kb4 when White is zugged. Interestingly, when I demonstrated this ending at the club the following week quite a few of the class made the same mistake. I guess they were already familiar with the idea of sacrificing to obtain a passed pawn but failed to calculate the resulting position. Now White is winning.)
52. f6? (Now it’s a draw. Instead, White can win by just capturing the pawn. His king can stop the g-pawn by entering the queening square, and then he can play f6, sacrificing to create an unstoppable passed pawn.) gxf6? (Black errs in turn. He could have draw by playing hxg3, when both players queen. Black will have an extra pawn but White has a perpetual check on the other side.)
53. gxh4 g3
54. Ke3 Kxc4
55. h5 (White has one pawn against three, but he’s going to promote first.) g2
56. Kf2 Kd3
57. h6 c4
58. h7 c3
59. h8Q c2

The last few moves have all been self-explanatory. When the pawn ending was reached, Black was winning. After a series of mistakes on both sides he found the winning plan, but then miscalculated badly. Now we reach an ending with queen against three pawns, two of which are on the seventh rank. White should win from here, but did he actually manage to do so? Don’t miss next week’s exciting episode.

Meanwhile, what lessons can be learnt from this ending so far?

1. You have to calculate the pawn ending before trading or proposing a trade of your last piece.
2. Being able to activate your king first is often decisive in pawn endings, but the centre is not always the best place. In this game Black’s winning plan (at least it should have been winning) involved marching the king down the a-file.
3. Learn the position type with two fixed pawns on the same file. If you can activate your king first you can attack the pawn from two squares, but it can only be defended from one square. Then all you have to do is run your opponent out of pawn moves and he’ll be zugged.
4. Sometimes you can win by sacrificing to obtain a passed pawn.
5. Positions with passed pawns on both sides need to be calculated accurately. You can’t just guess but really have to work it out. There may not be much point in sacrificing to get a passed pawn if your opponent’s king can move into the queening square.
6. Sometimes pawn endings can become queen endings. You have to be really good at queen endings as well as pawn endings.
