The stillness of the hunter

by Jonathan Speelman
12/7/2020 – After indulging in extreme violence with some of his favourite “hacks”, star columnist Jon Speelman changes gears and looks into a set of very interesting endgames. He focuses on zugzwangs, noting that “were it not for the obligation to move then almost all endgames with rook and pawn v rook would be drawn”.

Zugzwang

[Note that Jon Speelman also looks at the content of the article in video format, here embedded at the end of the article.]

In the last two columns we’ve indulged in extreme violence with some of my favourite “hacks”. We'll certainly return to this theme at some stage, perhaps with some games by the wonderful Rashid Nezhmetdinov: a player so violent that he was able more than once to out-hack Misha Tal himself.

But man and chess player cannot live by violence alone, and even Tal played some positional games including an archetypical pawn endgame that I remember from Peter Clarke’s book on him. This game (below v Bozidar Djurasevic) featured a race between competing pawn majorities, but perhaps the greatest contrast with violent tactics (though tactics may sometimes precede it) is seen in the preternatural stillness of zugzwang.

Zugzwang is the main feature of some games like Othello and also extremely prominent in draughts  which (I presume the 10x10 version) Nezhmetdinov played to a very high standard as well. In chess, it is very unusual until the endgame but underpins much of endgame theory. For example, were it not for the obligation to move then almost all endgames with rook and pawn v rook would be drawn since the defender could give up the rook for the pawn and then with K v K+R sit shtum at the critical moment — and the opposition would cease to have any meaning.

As it is, zugzwang is the path to victory in many endgames and I’ve got a few examples, of it and “pseudo-zugzwang” — manoeuvring to give the opponent the move in a position where he or she may have a decent choice but will have to work very hard to find it. Sometimes you don’t know yourself whether it’s pseudo or real but putting pressure on the opponent is sufficient reason to try.

We start with the Tal pawn endgame — which turns out actually to be drawn if Black defends correctly and then move on to a couple of pawn endings in which the critical point is that one or other king is denied a crucial square which means that his opposite number can outmanoeuvre him. Then there are a couple of studies — the first of them a theoretical rook ending, followed by three examples of zugzwang, pseudo or otherwise, from my own games.

I'd always believed that this is winning, but engines, which of course can play these sort of endings much better than people given just a little time to compute, tell me that it's still a draw. 31.Kd2 Kd7 32.Kd3 Kd6 33.c4 bxc4+ 34.Kxc4
34...e5? 34...g5! was correct though it's extremely complicated. At the board, so without an engine, giving you the assessments you'd be very unsure as Black whether you were drawing or losing. 35.fxg5 35.g3 gxf4 36.gxf4 e5 37.fxe5+ Kxe5 38.Kd3 Kd5 39.b4 h5 40.h4 f5 41.a4 f4 42.b5 axb5 43.axb5 Kc5 44.Ke4 Kxb5 45.Kxf4 Kc6 46.Kg5 Kd7 47.Kxh5 Ke8 48.Kg6 Kf8= 35...hxg5 36.b4 36.h3 f5 37.b4 37.g3 e5 38.b4 38.h4?? f4 and Black wins 38...Kc6 38...f4 39.g4?? is loisng 39.gxf4 exf4 40.a4 Kc6 41.Kd4 Kd6 42.Ke4 Kc6 43.h4 gxh4 44.Kxf4 Kd5 45.Kg4 Kc4 46.b5 axb5 47.axb5 Kxb5 48.Kxh4 39...e4 40.Kd4 e3 41.Kd3 Kc6 42.a4 Kd5-+ 39.a4 Kb7 40.Kd5 f4 37...e5 38.a4 f4 39.b5 axb5+ 39...a5 looks insane but apparently also draws, since White can't get in f3 without allowing the black e-pawn to run. 40.Kd3 Kd5 41.Ke2 e4 42.Kf2 Ke5 43.g3 e3+ 44.Kf3 Kd4 45.b6 Kd3 46.b7 e2 47.b8Q e1Q and Houdini gives this as equal though of course you'd rather be White. 40.Kxb5
Analysis of 34...g5! rather than e5 - White leaves the pawn on g2 40...Kd5‼ 40...e4? 41.Kc4 Kc6 42.Kd4 e3 43.Kd3 Kb6 44.g3 fxg3 45.Kxe3 Ka5 46.Kf3 Kxa4 47.Kxg3 Kb5 48.Kg4 Kc6 49.Kxg5 Kd7 50.Kf6 Ke8 51.Kg7 41.a5 Kd6 42.Kb6 42.Kc4 Kc6 43.Kd3 Kd5! 42...e4 43.a6 f3 44.gxf3 exf3 45.a7 f2 46.a8Q f1Q
