The reverse also has a reverse – Japanese proverb
In his parable The garden of forking paths the writer Jorge Luis Borges examines the relationship between past, present and future. What has gone before is stored up as facts, the future is a developing and dynamic process in which – in whatever manner – one of the logically possible continuations is selected.
This is a metaphor which quite fits the development of a game of chess over time. In chess it is the players who at each fork in the path take decisions as to what course their journey will take. They make these decisions by following with their imagination some of the possible ramifications to as great a depth as they can, by constructing according to their experience an evaluation of the position which will have been reached, and thus coming to a decision about their next move based on calculation and intuition.
The choice of just about each move is the result of evaluations which take some steps in time into the future of the actual position. Thus it is understandable that a manœuvre can sometimes be refuted by another one which arose on the basis of a more far-reaching vision of the future, and that the latter in its turn can be refuted by even deeper analysis, etc.
Position 202 with all its apparent latent energy is an illustration of this process of successive refutations by ever deeper mining operations. On seeing this landscape on the board, one irresistibly thinks that the end is nigh – but whose end?
N. N.–N. N., 1944
Black to move
Black acutely had to worry at once about the threatened mate on h7 and came up with the multi-purpose move 1...Rc7!!. White spontaneously resigned, since he had hallucinations about losing a rook. He spotted the sad fact that taking the agent provocateur leads to mate: 2.Qxc7 Qf3+ 3.Kg1 Qg2# or, even worse, 2.Rxc7 Qd1#.
The subtle counter to the rook move by 2.b5!! with the threat of 3.Bf8+ and mate did not occur to him. In analysis it was thought that Black would then have nothing better than seeking salvation in a draw with 2...Qd1+! 3.Rxd1 Rxb7. But there are also holes in this drawing idea, because the riposte 2.b5 was in its turn parried with a deeper insight into the microstructure of the position: instead of 2...Qd1+ Black can play for a win with the counter-parry 2...Qe2!!, because after 3.Bf8+ Kh5 4.Rxh7+ Kg4 White is mated in four moves at most. An operation which appears to win the day for Black.
But once again there is a reversal of fate: White does not make use of 3.Bf8+, but refutes Black’s winning attempt with the counter-offensive 3.Rxh7+!! Kung Fu fighting!! If Black now continues with his intended 3...Rxh7, then after 4.Bf8+ Kh5 5.Qxh7+ Kg4 6.Qxg6+ Kf3 7.Qh5+ Ng4 8.Qd5+ Kxf4 9.Bd6+ he has had it this time, because White wins the endgame. One flash of wit meets another!
But even then the last word has not yet been said: you see, Black’s best reply to the rook check 3.Rxh7+!! is 3...Kxh7! 4.Qxc7+ and he finally takes flight with 4...Kg8 into a position where he can expect a perpetual series of checks, because 4...Kh6 5.Bf8+ Kh5 6.Qh7+ Kg4 7.Qxg6+ Kf3 8.Qh5+ Ng4 9.Qd5+ Kxf4 10.Bd6+ would once more be favourable for White. So, all in all, a draw!
Is that the heart of the matter? Or can further deep-mining operations come up with something significantly different? The question remains open. But even as such, the above position is a metaphor for genuine fighting chess, a wild, good-going brawl with an open exchange of blows, in which every tempo demands the greatest of precision in positions loaded with dangers for both sides and where the analysis is marked by a series of delightful about-turns in the evaluation.
