Here is the moment where Black must try to justify his sacrifices.
22...gxf5?!
On the immediate 22...ƒc8 follows 23 fxg6 fxg6 24 †f3 and eventually Èd3-f4-d5 and White holds the extra material. On 22...ƒxc4 there comes 23 bxc4 …d2 24 fxg6! fxg6 (if 24... …xd1 White wins by 25 gxf7+ ‡g7 26 fxe8È+! †xe8 27 …bxd1 with two …s and a „ for the †) 25 †f3 …xd3 26 †f7+ ‡h8 27 …xb7ˆ.
In view of this, Black played to regain a pawn on the 25th move.
He also obtains the open e-file and threatens to double …s on the 7th rank.
“It was hardly possible to calculate that the disadvantage of the weakened ‡ position weighs heavier in certain variations,” commented Heemsoth.
After the game, Dr Hunter stated that 22...gxf5 was the decisive error, “Seeing no risk of losing — and here lay my mistake — I avoided the
complications of 22...f6 23 fxe6 …d2 (or 22...…d2 23 fxe6 f6)”.
Heemsoth claimed to have refuted this idea with the † sacrifice 24 Èf4!! …xd1 25 …fxd1 †b6+ 26 ‡h1 ƒe5! 27 …d7 ƒxf4 28 gxf4 …xe6 29 e5 with good chances of victory. An ingenious plan, indeed, but Black’s defence could be improved. One possibility is 25...†a5!?; others are to play ...†a6 at either move 26 or 27.
Black has to approach the defence schematically: his aim should not be to exchange ƒ for È but rather to use his … to eliminate the È and passed e-pawn. The black † can achieve considerable nuisance value operating on the a-file, and while the ƒ will be a defensive bastion on e5 it does not have to go there as immediately as Heemsoth supposed.
It is hard to give exhaustive variations, but here is a sample line showing how Black’s resistance will be very hard to overcome: 24 Èf4 …xd1 25 …fxd1 †b6+ 26 ‡h1 †a6!? when:
a) 27 e7 ƒe5! (not 27...…xe7?? 28 Èd5) 28 …d8 (28 Èd5 see line b) 28...†a2 29 …f1 ‡f7 30 Èd5 †xb3 31 c5 …xe7 32 Èxe7 ‡xe7 33 …fd1 †a4 (stopping the mating net).
b) 27 Èd5 ƒe5 28 e7 †a2 or 27 …d7 †a2 28 …bd1 †xb3.
23 exf5!?
Heemsoth rejected 23 Èf4 because of 23...…d2, but this does not work because 24 †h5 fxe4 25 Èxe6 †b6+ 26 Èc5 saves the piece, e.g. after 26...ƒd4+ 27 ‡h1 Black cannot take the È because of the threat to f7.
Game 30: Heemsoth-Hunter 153 However, White has no certainty of
winning the endgame after 23...fxe4 24 ƒxe4 †d4+ 25 †xd4 ƒxd4+ 26 ‡h1 ƒxc4 27 ƒxh7+ ‡xh7 28 bxc4 b6 29 …fe1Ÿ.
23...ƒc8
Others are weaker as White can hold his material advantage. Two examples:
a) 23...ƒd7 24 †g4+! ‡h8 25 …f2! †b6 26 c5 (26 ‡f1? †e3! 27 …d1 …xf2+!) 26...†a6 27 ƒf1 ƒb5 28 Èb4 ƒxb4 29 ƒxb5 †xb5 30 …xa2 ƒxc5+ 31 ‡g2‹. b) 23...†d4+ 24 ‡h1 ƒxf5 (24... ƒd7 25 Èf4!ˆ) 25 …xf5 …d2 26 †h5! and, in view of the mate threat, Black has no time to take the È.
24 Èf4?!
Heemsoth rejected 24 †g4+ because of 24...‡h8 25 Èf4 †d4+ 26 ‡h1 …ee2!, but White continues 27 †xe2! (27 †h5!? is also interesting.) 27...…xe2 28 Èxe2 †e3 29 Èxc3 †xc3 30 f6!, obtaining …s and two pawns for a †, with Black’s ‡ in dire straits. This must be winning for White, sooner or later. Now Black missed a defensive possibility.
24...ƒd4+?!
Played to avoid the † exchange, but Black should have welcomed it. Of the various other lines examined by Heemsoth and Hunter, there is only one we need to examine.
The right line for Black was 24... ƒxf5! 25 †xd8 …xd8 26 …bd1 ƒd4+ 27 ‡h1 (threatening both Èd5 and ƒxb7) when instead of 27...ƒc8? 28 ƒd5 (which should lead to a winning endgame for White), 27...ƒc2! gives good drawing chances. Neither 28
…d2 ƒxb3 nor 28 ƒxb7 ƒxb3! set White on the royal road to victory, and 28 …de1 ƒxb3 29 ƒd5 is countered by 29...b5! White is left with only the ghost of his advantage.
White can play more subtly but I don’t see an obvious way to get real winning chances. For example, if 26 …bc1 ƒb2 27 …ce1 Black forces exchanges by 27...…d2, e.g. 28 …e2 ƒd4+ 29 ‡h1 …xe2 30 Èxe2 …xe2 31 …xf5 …e1+! when after 32 …f1 …xf1+ 33 ƒxf1 b6 he finds salvation in an opposite-coloured ƒ ending a pawn down, while if 32 ƒf1 …b1 33 …f3 …b2 and it’s not clear how White can improve his position.
Black must have his plan led to a draw by perpetual check, so he saw no need to examine unclear lines leading to endgames a pawn down. White, having won the game, probably never found reason to re-examine notes of variations that never occurred.

White’s play is very fine from this point to the end. Now that it is still a middlegame after all, he is back in the

driving seat — but with Black’s …s and ƒs active, it is no easy matter to find the right line. Logic tells us that the È must be activated to the maximum, but this move offers the exchange and surrenders e2 to the black …s.
26...ƒxb1
Not 26...…ee2 27 †xd4 …xg2 28 …xf5 when Black can resign, but 26...…xg2!? is interesting:
a) Heemsoth planned another † sacrifice: 27 …xf5!? …g1+ 28 †xg1 ƒxg1 29 ‡xg1, which both he and Dr Hunter assessed as strategically won for White because of his central È, but instead of Heemsoth’s line 29...…f8 30 …bf1 †a8 31 Èf6+ ‡g7 32 …g5+ ‡h8 (32...‡h6? 33 h4ˆ) 33 …h5! ‡g7 34 …xh7+ ‡g6 35 h4! …h8 36 h5+ ‡g5 37 Èe4+ ‡g4 38 …f4+ ‡h3 39 …h4#, Black has the better defence 29...‡g7 30 …bf1 †d7 because the white queenside pawns become vulnerable if he goes in for a liquidation on f7.
b) If 27 ‡xg2 ƒe4+! 28 ‡h3 †g5! £...†h6+ (Heemsoth gave 28...…e6, but then 29 †xd4 …h6+ 30 ‡g4 …g6+ 31 ‡f4ˆ) 29 …f4 …e6 30 …xe4 …xe4 and Black’s activity is worth the pawn. Maybe White should try 28 …f3 here.
27 †xd4 ƒg6
27...…xg2 does not work: 28 Èf6+ ‡h8 29 Èd7+ ‡g8 30 ‡xg2 …e2+ (30...ƒg6 31 Èf6+ ‡h8 32 †b2!, or 31...‡f8 32 Èxh7+! ƒxh7 33 †h8+ ƒg8 34 †h6+ ‡e7 35 …e1+, or 33...‡e7 34 …e1+ wins) 31 ‡g1 ƒe4 32 Èf6+ ‡g7 (32...†xf6 33 …xf6!) 33 Èh5+ ‡h6 34 †g7+ and mates.
28 Èf6+ ‡f8
After 28...‡h8 29 ƒd5! Black can have an early bath, e.g. 29...…ee2 30 Èg4+! f6 (30...‡g8 31 ƒxf7+) 31 …xf6 …e1+ (31...ƒe4+ 32 …f3+) 32 …f1+.
29 Èd7+!?
Heemsoth thought White has no win after 29 Èxh7+ ƒxh7 30 †h8+ ƒg8 31 †h6+ ‡e7 32 …e1+ ‡d7 33 …d1+ ‡c8 34 …xd8+ …xd8. He gave the continuation 35 h4 …d1+ 36 ‡h2 …dd2, but after 37 †f8+ and an exchange of ƒs, the † and passed h- pawn are probably winning in fact.

This is the position on which Dr Hunter had pinned his hopes, but he totally misjudged it! Consider the statement in ‘British Chess’ (based on Heemsoth’s notes) that: “After 30 ƒxb7 …ae2!, threatening ...…e1, the tables are quickly turned and White must seek the draw”.
On the contrary, after the awful 30...…ae2?! White’s winning chances markedly revive by 31 Èf6+ ‡f8 32 †h4 and Black does not have time to play ...…e1. Instead, given a glass of his favourite whisky, Dr Hunter would
Game 30: Heemsoth-Hunter 155 Èf6+ ‡g7 is also fatal on account of the discovered check after 36 †e5!, e.g. 36...†b8 37 Èe8+ ‡h6 38 †g7+ ‡h5 39 Èf6# (Heemsoth).
c) 33...…h8 fails to 34 Èxh5+ ‡h7 35 …xf7+! followed by mate.
d) 33...†e7 34 Èxh5+ ‡h7 35 Èf6+ ‡g7 and now in the original notes, 36 Èxe8+ †xe8 37 ƒd5! ‡h7 38 h5?? is given, overlooking 38... ƒe4+! and White gets mated. Instead, 36 h5ˆ as 36...…h8 does not work because of 37 h6+ …xh6 38 †xh6+! and a È fork on g8 picks up the black †.
e) 33...…a6! was not considered in the players’ notes but may be the lesser evil: 34 Èxh5+ ‡g8 35 Èf6+ …xf6 36 †xf6 †xf6 37 …xf6 …e3. However, the … ending must be winning for White, given the extra pawn on each wing.
34 Èxh5+ ‡g8
After 34...‡h7 Heemsoth found an elegant refutation in 35 …xf7+! …xf7 36 †xd8 ƒxh5 37 †d5 ƒg6 38 h5.
35 ƒd5! ‡h7
This is the only defence against White’s double threat of 36 †xg6+ and 36 ƒxf7+, because 35...†d6 fails to 36 Èf6+ ‡g7 37 Èe8+! …xe8 38 …xf7+ ‡g8 39 …d7+.
36 Èf6+ ‡g7 37 Èg4!
The last and most decisive move of the È, threatening 38 †h6+ ‡g8 39 Èf6#.
37...†d6
The mate in two is thus prevented but the h-pawn will strike the decisive blow, as the culmination of the combination begun at move 30.
38 h5 1–0
surely have found 30...ƒf5! 31 Èf6+ ‡h8!! (not 31...‡f8? 32 Èxh7+ ƒxh7 33 †h8+ ‡e7 34 …e1+ ‡d7 35 …xe8 †xe8 36 ƒc6+!) 32 Èd5+ f6!! (not 32...‡g8, hoping for that perpetual, because of 33 ‡g1! and Black’s counterplay vanishes) and Black is saved, maybe even with some advantage. For now if 33 †xf6+ †xf6 34 Èxf6 …ee2 with the notorious “blind swine”, while if 33 ‡g1 Black sinks his anchor with 33...…e5.
Also, where is the perpetual check that Dr Hunter expected White to take? True, a draw by repetition could come about via 30 Èf6+ ‡f8 (30... ‡h8? 31 ƒd5!) 31 Èd7+ ‡g8 32 Èf6+ etc. but after the first check White could transpose to the note to White’s 29th
move by 31 Èxh7+! ƒxh7 32 †h8+ ƒg8 33 †h6+ ‡e7 34 …e1+ ‡d7 35 …d1+ ‡c8 36 …xd8+ …xd8 37 h4.
30 h4!!
The threat is 31 h5 ƒxh5 32 Èf6+ etc., so Black’s reply is forced.
30...h5 31 Èf6+ ‡f8 32 †f4!
Threatening 33 †h6+ ‡e7 34 Èd5+ ‡d7 (34...‡d6 35 …xf7) 35 ƒh3+ winning. Black now tries to conciliate White by returning the exchange, but White builds up his position move by move, renouncing distractions.
32...‡g7 33 †g5!
After 33 Èxe8+ †xe8 the strong black … hinders winning attempts, e.g. 34 †f6+ (34 ƒxb7? †e2) 34...‡h7 35 †f3? (35 †f4 †e2) 35...…xg2!.
33...…e7
a) Not 33...…ee2? 34 Èxh5+ and 35 †xd8.
