This game between Howard Staunton and Elijah Williams is very illustrative of the importance of the different kind of oppositions in chess. If you haven’t read the lesson about the opposition it is probably better to read this first.
As you will see Staunton has lost the game, but you have to know that the virtual opposition was something nobody was aware of in 1851. Without these kind of guidelines it is very difficult to play this kind of endgame the right way.
But with all the lessons you have learned in this series the endgame is rather easy to play.
13… Nc5 14.Nd4 Bxg3 15.fxg3 Nxd3 16.Qxd3 Rfe8 17.Rae1 Bh5 18.Qb5 a6 19.Qa4 b5 20.Rxe8+ Nxe8 21.Nxb5 Qc6 22.Qh4 axb5 23.Qxh5 Nf6 24.Qe5 Qb6+ 25.Kh1 Rxa2 26.Qf5 Qe6 27.Qb1 Ra8 28.Qd3 Qc6 29.Qf5 Qe6 30.Qd3 Qc6 31.Nf3 Qc4 32.Qd1 Re8 33.Nd4 b4 34.Nf5 Re6 35.Qf3 bxc3 36.bxc3 Qe4 37.h3 Qxf3 38.gxf3 Re2 39.Nd4 Rd2 40.g4 g6 41.Ra1 Nd7 42.Ra8+ Kg7 43.Rd8 Ne5 44.Rxd5?
And now the most interesting part of the game starts.
52.hxg5 this is a draw, but White has to play the right moves 52…Kf7 53.Ke3 Ke6 54.Ke4! White has the opposition. 54…Kd6 55.Kd4! White has the opposition, but that is not the only thing he has to assure. White has to stay in the neighbourhood of the pawn on h5, according to the pawn square rule. 55…Kc6 56.Ke5??
( 57… h4 will meet 58.Ke4 h3 59.Kf3 h2 60.Kg2 h1=Q+ 61.Kxh1 Kc5 and White’s King will move between g2 and h3 enabling him to occupy g3 as soon as Black captures the pawn 62.Kg2 Kd5 63.Kh3 Ke5 64.Kg2 Kf5 65.Kh3 Kxg5 66.Kg3 and White has the opposition. )
58.Ke4 Virtual opposition 58…Kb5 59.Kd5 Horizontal opposition 59…Ka4 60.Ke4 Distant opposition 60…Kb4 61.Kd4 Kb3 62.Kd3 Kb2 63.Kd2 Kb1 64.Kd1 and the game will result in a draw. 64…Kb2 65.Kd2 Kb3 66.Kd3 Ka4 67.Ke4 Kb5 68.Kd5 Kb6 69.Kd4 Kc6 70.Ke4 Kd6 71.Kd4 and we have seen a lot of oppositions preventing black to capture the pawn.
The next lesson is about the Trébuchet.
