The joy of hacking

by Jonathan Speelman
11/1/2020 – Former world number 4 and long-standing columnist Jon Speelman shares one of the most complicated games he has ever played — a win he got over Britain’s first grandmaster Tony Miles when he was 19 years old. How did he do it? Speelman concludes his analysis: “There’s no point in looking for consolidation when the board is awash with lava.” | Pictured: Tony Miles (sitting) and Michael Stean at the Zonal Tournament 1978 in Amsterdam | Photo: Dutch National Archive

Winning starts with what you know
The new version 18 offers completely new possibilities for chess training and analysis: playing style analysis, search for strategic themes, access to 6 billion Lichess games, player preparation by matching Lichess games, download Chess.com games with built-in API, built-in cloud engine and much more.

Above all, fight!

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

Magnus CarlsenIt’s generally agreed that with “perfect play” a game of chess “ought” to end in a draw. A White win seems very unlikely, and a Black one — the initial position being decisive zugzwang — almost inconceivable if not proven mathematically.

The margin of error actually seems to be fairly large, and so for a strong player to lose he or she has to be put under considerable pressure. This can be done quietly through long positional manoeuvring and determined endgame play — Magnus Carlsen's schtick most of the time — or by more violent means: hacking.  

Scratch almost any strong player and beneath a possibly placid exterior you will find a sleeping hacker: a player revelling in violent tactical battles (especially if they are on the right side of them). And today we celebrate the joy of hackery with one of the most complicated games I’ve ever played.

This was in the 1975 British Championship in Morecambe. When I was still 19 and not yet even an IM. It was, apparently (I consulted John Saunders’ Britbase), in the ninth of the eleven rounds that I played White against Tony Miles, who the next year would become Britain’s first grandmaster. Tony wound me up in the opening and becoming nervous about what was in reality a perfectly playable position by normal means, I began to hack and continued in a game which became ever more complex and hysterical.

I first annotated it around 1975 for The Chess Player, a now defunct periodical and had another look for my Best Games book about 1997, when available chess engines were beginning to make a difference. I’ve had another look with today's crop and made some more alterations.

The most important point about the game is not the exact variations which you might or, more likely, might not find during a game, but the mindset you require once things really kick off. There’s a point of no return beyond which the initiative is king and formal material balance of only limited importance. You must calculate as much as you can, try to stay reasonably calm, and above all fight!

We’ll continue in a fortnight with some recent examples of extreme violence at the board.

1.c4 This is in The Chess Player Vol 10 No 52 game 320. I started with the version in my Best Games book (BG form now on) and then edited it using Houdini. It's an early example of the English Defence - a family of lines in which Black plays a very early b6, such as 1.d4 e6 2.c4 b6: and an opening which I've used myself as Black on and off for much of my career. b6 2.Nc3 Here are a couple of games with a quick ... Qh4. Mine followed Polugaevsky v Korchnoi for a long time though I didn't realise that it was exactly the same until we chose opposite wings to castle on. 2.d4 Bb7 3.Qc2 e6 4.e4 Qh4 5.Nd2 Bb4 6.Bd3 Qg4 7.Kf1 f5 8.Ngf3 Bxd2 9.Ne5 Qh4 10.Nf3 Qh5 11.Bxd2 Nf6 12.exf5 Bxf3 13.gxf3 Nc6 14.Bc3

6...Qh4 7.Bd3 f5 8.g3 Qh5 9.f3 7.h4!? I gave a long explanation of why I played this in BG. Essentially I started off very optimistic then got worried about Black's counterplay after ...f5 and, now underestimating my position, chose h4 to discourage f5 since the bishop will be supported on g5 in the event of the knight recapturing. 7.Bd3 f5 8.Nf3 fxe4?! 9.Bxe4 Bxe4 10.Qxe4 Nbc6 11.d5! is too quick for Black. 7.Nf3 7...0-0 7...d5 8.cxd5 exd5 9.e5 c5 10.Nf3 7...f5 8.exf5 Nxf5?! 8...exf5 9.f3 intending Bd3,Ne2 =/ += 9.Bg5 Qc8 10.Rh3! intending g4 h6 Sugestion 5/10/1994 11.g4!? 8.Rh3!? d6 8...f5 9.Bd3 9.h5 Perhaps JS 2020 e5 10.g4 Nd7 11.Be2 Qe8 9...e5 10.f4!?

Unclear is optimistic. If Black ignores the "threat" then he should be better. 18...Kh8!? 18...h6 18...h5 18...Nxd5! is indeed given as better for Black by the engine and that was my feeling in BG 19.Bxh7+ Kh8 20.Ne5 20.Bg6 Ne3+! 20...Nc3+ 21.Qxc3 Qxg6 21...Bxf3+ 22.Qxf3 Qxg6 23.h5 22.Ne5 21.Bxe3 Qxe3 20...Nxf4!

It was far too difficult to play really accurately at the board, and even when I analysed it later in detail with some help from early engines, I left gaps which I've now attempted to plug. The most important lesson is one which is simple to state though hard to implememt well at the time. Once you start hacking and reach the point of no return, then you have to keep going. There's no point in looking for consolidation when the board is awash with lava.

To compliment my madness, a nicely hackety game I saw last night as I write.

Since I spend some time streaming, I sometimes watch how other people do it and I happened to drop into part of a simul that Dutch GM Benjamin Bok was giving on another server. Most of the games were pretty straightforward but in one of them his opponent really went for him — as you should in a simul. Bok knew that the sacrifice wasn't supposed to work — since he’d had a previous game in the line. But of course he couldn’t remember the exact details in these circumstances and at one moment his opponent missed a very pretty mate.

1.d4 I've annotated this mainly from a practical point of view while trying to tell the true story as well. From a human perspective, chess is not an exact science but a battle in which you should try to optimise your chances. So a move may not be best "in theory" but very effective in the given circumstances. d5 2.Nf3 Nf6 3.c4 c6 4.Nc3 e6 5.e3 Nbd7 6.Qc2 D45 Semi-Slav Defense: Stoltz Variation Bd6 7.b3 0-0 8.Be2 b6 9.0-0 Bb7 10.Bb2 Qe7 11.Rad1 Rad8 12.Rfe1 Rfe8 13.Bf1 e5 14.dxe5 Nxe5 15.Nxe5 Bxe5 16.cxd5
16...Bxh2+?! This shouldn't quite work against "perfect" defence, but was a very good choice in a simultaneous exhibition since the last thing the simul giver wants is to have to calculate accurately. 16...cxd5 17.Nb5 17.Bb5 Rf8 18.Bd3 Rc8 19.f4 Bd6 20.Bf5 Rc6 21.Qd2 Bc5 22.Nb5 Bb4 23.Bc3 17...Rc8 18.Qb1 d4 was Bok's previous game: 18...Bxb2 19.Qxb2 Ba6 20.a4 Bxb5 21.axb5 Rc7 22.Rc1 Rec8 23.Rxc7 Qxc7 24.Ra1 Qe7 25.Rc1 Rc5 26.Qa3 g6 27.Rxc5 bxc5 28.Qa5 Qb7 29.Qd8+ Kg7 30.Qd6 Qb6 31.Qe5 h5 32.h3 Kg8 33.Be2 d4 34.Bc4 Qd8 35.Qxc5 d3 36.Qxa7 d2 37.Qxf7+ Kh8 38.Be2 d1Q+ 39.Bxd1 Qxd1+ 40.Kh2 Qd6+ 41.f4 Nd5 42.Qe8+ Kg7 43.Qc6 Qd8 44.e4 Nxf4 45.b6 Qd2 46.e5 Nd5 47.b7 Qf4+ 48.Kg1 Qe3+ 49.Kf1 Qd3+ 50.Ke1 Qe3+ 51.Kd1 Qxb3+ 52.Kc1 Qa3+ 53.Kb1 Qb3+ 54.Kc1 Qa3+ 55.Kb1 1/2-1/2 (55) Ding Liren (2811) -Shankland,S (2705) chess. com INT 2019 19.h3 Ne4 20.Nxd4 Qh4 21.Re2 Nxf2!? A very good try even if engines can refute it. It is certianly my hand's choice. 22.Nf5 22.Rxf2 Bh2+ 22...Qg3 23.Nf3 Bxf3 24.Bxe5+- 23.Kxh2 Qxf2 24.Bc1± 22...Nxh3+ 23.gxh3 Qg5+ 24.Bg2 Bf3 25.Bxe5 Rxe5 26.Rc1 Rce8 27.Rf2 Bxg2 28.Rxg2 Qxf5
Bok's previous game in the line as a result of which he knew that Bxh2+ "shouldn't work". 29.Qxf5 Rxf5 30.Rc7 h5 31.Rxa7 Rxe3 32.Kh2 Rff3 33.Rd2 Rxh3+ 34.Kg2 Reg3+ 35.Kf2 Rh2+ 36.Kxg3 Rxd2 37.b4 g5 38.a4 Rd3+ 39.Kg2 Rb3 40.b5 Ra3 41.Ra6 h4 42.Rxb6 Rxa4 43.Rc6 Rb4 44.b6 Kg7 45.Kh3 f5 46.Rd6 Rb3+ 47.Kg2 g4 48.Rd5 h3+ 49.Kh2 Kf6 50.Rd6+ Kg5 51.Rc6 Rb2+ 52.Kg1 g3 53.Rc8 Rb1+ 0-1 (53) Bok,B (2624) -Smirnov,P (2544) chess.com INT 2020
17.Kxh2 Ng4+ 18.Kg3 18.Kg1 Qh4 19.Bd3 Rd6! apparently good for Black - Houdini 19...Qh2+ 20.Kf1 Qh1+ 21.Ke2 Rxe3+ 22.Kd2 22.fxe3?? Qxg2# 18...Qg5?! (1.12 ? 1.85) Inaccuracy. Bc8 was best. 18...Bc8 19.f4 Qh5 20.dxc6 Bxc6
21.Rxd8? Missing a deadly trick in the obvious main line. 21.e4! seems to defend, though it would still be very hard in a simul. g5 22.fxg5 Qxg5 23.Qc1 Ne3+ 24.Kf3 Qg4+ 25.Kf2 25.Kxe3? Qg3+ 26.Ke2 Bb5+ 25...Nxd1+ 25...Rxd1 26.Rxd1 Nxd1+ 27.Nxd1! Qxe4 28.Kg1 and White has a winning attack. 26.Nxd1 Rxe4 27.Ne3 Rf4+ 21...Qh2+ 22.Kxg4 h5+ 23.Kf5
23...g6+? Missing a very pretty win. 23...Bd7+! 24.Rxd7 Qg3 I saw 24...Qh4 myself. 25.Re7 Rxe7 and mate next move. 24.Kg5 The king now reaches h6 and White is dead. Qg3+?! (15.96 ? Mate in 9) Checkmate is now unavoidable. Rxd8 was best. 24...Rxd8 25.Rd1 25.Kh6 Rxd8 26.Ne4 Qxe1 27.Qxc6 Qb4 28.Nf6+ Kh8 29.Nd5+ Kg8 30.Nxb4 Kf8 31.Nd5 Normal. Black resigns. g5
