'This romantic opening is a real rarity at top-level chess. Probably the greatest expert on this line right now is England's Grandmaster Joe Gallagher.' - Nigel Short in The Daily Telegraph The King's Gambit has always been a great favourite of tactical players. However, since its heyday in the nineteenth century, it appeared only sporadically in Grandmaster chess. Recently, this has begun to change, and the King's Gambit has once again become a force to be reckoned with. A whole host of new ideas have appeared, many of them introduced into international competition by the author himself and explained in this book.

The King’s Gambit is, of course, an opening with a great history, but for the larger part of this century it has been lying dormant, a rare visitor to tournament practice. However, I am inclined to take the optimistic view and regard its demise as purely a matter of fashion.
The Spanish Game (or Ruy Lopez, who incidentally was the first person to publish King’s Gambit analysis) has now ruled the open game for countless years, but there is evidence that its reign could be drawing to a close. The last few years have witnessed an upsurge in the popularity of Scotch’s, Vienna’s and Four Knights’, including at the highest level - Kasparov used the Scotch with success in his latest match with Karpov, and Short employed various antiquated systems in his most recent Candidates’ tussle with Speelman, even a couple of King’s Gambit Declineds by transposition. I believe it can only be a matter of time before the King’s Gambit (proper) joins in this revolution. I know that many players have been toying with the idea of introducing the King’s Gambit into their repertoire, but have not yet found the courage to push that f-pawn two squares on their second move. My hope is that this book will help to allay many of their fears.
Winning With the King’s Gambit, as the title should inform you, is a look at this opening from the White point of view. Whilst I have endeavoured to remain as objective as possible in my assessments of positions, much more time has been devoted to finding new ideas for White, rather than attempting to refute existing theory where White already stands well. I see this as a task for our future opponents.
The theoretical revival of the King’s Gambit is really not that surprising, as it has always been based on sound positional principles. If Black accepts the gambit, then White is normally able to build a strong centre and if Black gives (or loses) the pawn back, White will also achieve a space advantage on the kingside. When Black plays to keep the material with... g5, then White usually does best to undermine the pawn chain as quickly as possible by playing h4 (see the chapters on Fischer or Kieseritzky, for example), forcing Black to advance... g4, which can often lead to a wrecked kingside.
The format of this book is one which is becoming increasingly popular and involves studying the opening through a series of annotated games. This is extremely important, as it enables the reader to familiarise himself (or herself) with the middlegame positions (and occasionally endgames) which arise from the King’s Gambit.
This is a book for the practical player (but also one who will appreciate the special buzz around this opening), and for that reason not all variations of the King’s Gambit are included, but only those which offer White good chances of obtaining the advantage. However, the chosen variations have been analysed in depth, as often it can be just as important to know which variations are bad (and why) as to which are good. The repertoire is based on the King’s Knight Gambit, so my apologies to those fans of the Bishop’s, and various other third move gambits, but my advice to you is to start playing 3 ♘f3.

Over the last few years this variation has developed into the most popular way of accepting the gambit. Personally, I feel quite happy about this as Black seems to be struggling in most of the lines. I only hope that this chapter won’t frighten off any potential opponents!
After his famous defeat against Spassky at Mar del Plata 1960, the great Bobby decided to refute the King’s Gambit. In the summer of 1961, the American Chess Quarterly published his analysis. “A high-class waiting move”, was how he described 3... d6.
The main point of the variation is demonstrated after the moves 4 d4 g5 5 h4 g4. White does not have the possibility of 6 ♘e5, as in the Kieseritzky Gambit. Therefore he has to go ‘all in’ with 6 ♘g5 (not to be recommended, I’m afraid) or return to base with the rather sad-looking 6 ♘g1 (3), when quite a comical position has arisen on the board - after six moves neither side has managed to get a piece off the back rank!
At the moment, Black is a pawn up but f4 is seriously weak and, if White manages to restore material equality without any sideeffects, Black’s punctured kingside will not allow him an easy game. Let’s have a look at some games to see how Black attempts to solve his problems.

White does have other possibilities, but 4 d4 is clearly the most critical. However, the plan of ♗c4 followed by d3 is also interesting and can be seen later in games 9 and 10.

g5
Other moves have been tried from time to time without much success, for example: 4... ♘f6 5 ♘c3 ♘h5 6 ♗e2 (maybe 6 ♕d3, ♗d2 and 0-0-0) 6... ♗g4 7 0-0 c6 (7... g6 8 ♘d5) 8 ♘e1! ♗xe2 9 ♕xe2 g6 10 ♘d3 leaves White with a clear advantage.
5
h4
5 ♗c4 is illogical: if White wants to play this he should play it on the fourth move, as then Black is forced play... h6. The Dutch player Bosboom has experimented with 5 ♘c3, his idea being 5... g4 6 ♗xf4 and on with the game. His game with Ermenkov, Amsterdam 1985, continued instead: 5... ♗g7 6 h4 g4 (6 ... h6 should be considered) 7 ♘g1 ♘c6 8 ♗b5 ♗d7 9 ♗xc6 bc 10 ♗xf4 ♘e7 11 h5 with advantage to White. Further tests awaited!

♘g1
As already mentioned, 6 ♘g5 runs into trouble. Not because of 6... h6 though, as after 7 ♘xf7 White has a decent version of the Allgaier Gambit (if there is such a thing), but 6... f6! and after 7 ♘h3 gh 8 ♕h5+ ♔d7 9 ♗xf4 ♕e8! 10 ♕f3 ♔d8 White doesn’t have enough for the piece (Fischer).

Black decides to give back his pawn in order to disrupt the white kingside. The other possibilities: 6... ♘f6, 6... ♗h6 and 6... ♕f6, will be considered in games 4 to 8.

7 ♗g5 can be seen in games 2 and 3, whilst 7 ♗e3 occurred in the game Popovic - Spassky, New York 1986. However, after 7... ♗e7 8 ♗f2 ♘f6 9 gf ♖g8 10 ♗g2 ♘c6 11 ♘c3 gf 12 ♗xf3 ♘g4, Black had the initiative

♗e3
This sensible developing move minimises the disruptive value of the check on h4. During the game I was sorely tempted to play 8 h5 but couldn’t quite summon up the courage to do so. Only Mark Hebden has, in his game with R. Alvares, Costa del Sol 1987, which continued: 8... ♗h4+ 9 ♔e2 (Not such a pretty place for the king, but we still have our h-pawn) 9... gf+ 10 ♘xf3 ♗g4 11 ♔d3 ♘c6 12 c3 ♘e5+?! (I have a vague memory of looking at 12... f5 with Mark and after 13 ♗h3 fe+ 14 ♔xe4 ♘f6+ 15 ♔d3 coming to the conclusion that Black’s king was in more trouble than White’s. Maybe we were drunk!) 13 de de+ 14 ♔e3! ♕xd1 15 ♗b5+ c6 16 ♖xd1 cb 17 ♖d5 and White had the better endgame.

This new idea of Conquest’s certainly seems to be Black’s best try. After 9 ... ♘c6 10 ♘c3 ♗f6 (or 10... ♗g5 11 f4 ♗f6 and White’s centre is stronger than Black’s passed pawns) 11 ♗b5 ♗d7 12 ♗xc6 bc 13 fg White held the advantage in Gallagher - Konrad, Lloyds Bank 1985.

10 c3 also deserves consideration, but at the time I was afraid that I wouldn’t be able to support my centre, as it would come under heavy pressure from moves such as ... ♘c6, ... ♗f6, ... ♕b6 etc.

(This vacates the f1-square for the king) 10... g3+ 11 ♔xg3 ♖g8 12 ♔f2 ♘g4+ 13 ♔f1 and White stands clearly better, for example: 13... ♗xg5 14 hg ♕xg5 15 ♕xg5 ♖xg5 16 ♖xh7 ♘e3+ 17 ♔f2 ♖xg2+ 18 ♔xe3 ♖xg1 19 ♖h8+ ♔d7. A very curious position has arisen with both sides having terrible problems completing their development. However, the weakness of the black f-pawn enables White to gain a decisive advantage with 20 ♖f8!
(c) 8... h6 is examined in game 3.

Black had banked on something like 9 ♗e3 f5 with a good game. Now 9 ♗h6 f5 10♗g7! ♗xh4+ 11 ♔d1 and any compensation Black appears to have is just illusory. For example: 11... fe 12 ♗xh8 ♗g5 13 ♕e1! By skilfully manoeuvring his king and queen, White has achieved a won position. If now 13... d5, then 14 gf gf 15♘xf3♗g4 16♗e2!; or 11... ♗f6 12 ♗xh8 ♗xh8 13 ♖xh7 (or 13 gf) wins for White.

(b) 20 ♖xd7!? ♗xd7 21 ♘e4 ♕e7 22 ♘f6+ with a very dangerous attack, but then I thought “why sacrifice at all?”. After 20 ♖d5, White has an attack of similar strength, but is only a pawn down.

Therefore it’s better not to ‘sac’ the exchange and play instead 22 ♘d6+ ♔f8 23 ♕a3! Black is forced to play 23... c5, as 23... ♔g8 loses to 24 ♘xc8 cd 25 ♘e7+ ♔h7 26 ♕d3+.

White develops, keeping his options open. Maybe he will play ♘ge2 or perhaps a plan with ♕d3, ♗d2 and 0-0-0. 7 ♘e2 is also quite playable and, after 7... ♕f6 8 ♘bc3 ♘e7, we transpose to game 8.
7
...
c6
Black secures his d5-square in order to be able to defend the f-pawn with his queen. 7... ♗e6 will be seen in game 6; 7... ♘c6 and 7... ♘f6 in game 7.
8
♘ge2
There are a couple of interesting alternatives:
(a) 8 ♗c4. White understandably prefers to develop his bishop before playing ♘e2, but he does leave himself exposed to counterplay on the queenside: 8... ♘f6 9 g3!? ♕e7?! (I wonder what White intended after 9... b5!, as 10 ♗d3 ♘h5 11 ♘ge2 doesn’t work in this position: 11... ♘xg3! 12 ♘xg3 fg 13 ♗xh6 g2 14 ♖g1 ♕xh4+) 10 ♘ge2 b5 11 e5! de 12 de ♕xe5 13 ♗xf 4 ♗xf 4 14 gf ♕e7 15 ♗d3 ♘bd7 16 ♕d2 with a good game for White, Sanchez Almeyra - Anic, Lyon 1990.
(b) 8 ♕d3 b6!?. White often has to worry about this move after an early ♕d3. The f- and the g-pawns take away a lot of squares on the third rank (8... ♕f6 is less good, as Black is just asking for e5). 9 ♘d1!? (Recommended by Bangiev) 9... ♗a6 10 c4 d5 11 ed cd 12 ♕e2+ ♕e7 13 ♘f2!? ♘f6 14 ♕xe7+ ♔xe7 15 ♘e2 ♗xc4 16 ♘xf4 and White has just enough compensation for the pawn
8

♕f6 (16)
8... f3 9 ♘g3 (9 ♘f4 is also possible) 9... ♕f6 10 ♗xh6 f2+ (10... ♘xh6 11 ♕d2 is also pleasant for White) 11 ♔e2 ♘xh6 12 ♕d2 and White wins back the pawn with advantage.
9
g3!
In this way, White takes control of all the dark squares. True, he allows Black a protected passed pawn on f3, but his central control is so great that this is hardly relevant.
9
...
f3
9 ... fg 10 ♘xg3 ♗xc1 11 ♖xc1 doesn’t help Black. After 11... ♕f4 (otherwise White can develop harmoniously) 12 ♘ce2 ♕e3 13 ♕d2, White achieved a better ending in Christiansen - Lobo, San Jose 1980, but 13 c4 followed by ♖c3 to expel the lone intruder looks even stronger to me.
10
♘f4
♕e7
Black has to play with extreme care. The slightest slip and it will all be over. For example: 10... ♘e7? 11 e5! de 12 ♘e4 ♕g7 13 ♘h5 ♕g6 14 ♘hf6+ ♔f8 15 h5 ♕g7 16 de ♘d7 17 ♕d6 1-0 Craig - Dempster, Corr. 1985; or 10... ♗xf4?! 11 ♗xf4 b5? (What is Black doing?) 12 ♕d2 ♕e7 13 0-0-0 ♘d7 14 ♗xb5! ♗b7 15 ♗c4 a5 16 ♖he1 ♘b6 17 ♗d3 ♘d7? 18 ♘d5 1-0 Hebden - Cantero, Spain 1986. That was certainly a bad day at the office for Senor Cantero. Basically, whatever Black does, White is going to complete his development and then try to smash open the centre.

(Now Black has to take the rook otherwise White will simply munch his way through the seventh rank) 22... ♘xe7 23 fe+ ♔e8 24 ♗f6! ♖g8 25 ef=♕+ ♖xf8 (The point of 24 ♗f6 is revealed in the variation 25... ♔xf8 26 ♕b4+) 26 ♕b4 and wins
(b) 16... 0-0-0 17 ♘cd5! (White will pursue the black king wherever it runs) 17... cd 18 ♘xd5 ♕e8 (18... ♕e6 then 19 ♕a5 b6 20 ♕xa7) 19 ♕a5 ♔b8 20 ♕c7+ ♔a8 21 ♗e4! ♗c8 (21... ♗c6 22 ♘b6+ ab 23 ♖d3 or 21... ♖b8 22 ♖d3 with the wonderful threat of 23 ♕xd7!!) 22 ♖d3 with a crushing attack.

♗e6 (20)
Black finds a novel way of protecting his d5-square (in order to play... ♕f6 if necessary). The text has one important advantage over 7... c6: the d6-square is not weakened, which means that the dangerous attacking plan of e5 and ♘e4 will lose a lot of its potency.
White can, of course, gain time by attacking the bishop with d5 but this is extremely anti-positional and should only be played if there is a very strong follow up.
8
♕d3
I decided to play a plan with ♕d3, ♗d2 and 0-0-0 as Black can no longer harass the queen with... b6 and... ♗a6. However, if I get this position again I think I would prefer 8 ♘ge2, immediately fighting for some space on the kingside. Play could continue: 8... ♕f6 9 g3 (9 ♕d2!? f3 10 ♘f4 ♗xf4 {or 10... fg 11 ♗xg2 ♗xf4 12 ♕xf4 ♕xd4 13 e5! with good play for White} 11 ♕xf4 ♕xd4 12 gf with play for the pawn) 9... fg (9... f3 10 ♘f4 is pleasant for White) 10 ♘xg3 ♗xc1 11 ♖xcl and, in spite of his material deficit, White has the better chances (The position is very similar to the note to Black’s ninth move in Gallagher - Jackson).
8
...
a6!
This looks like a loss of time, but it turns out that without a possible ♕b5 White’s options are severely limited. If instead 8... ♘c6 then 9 ♘ge2 ♕f6 10 ♕b5! is difficult to meet.
9
♗d2
♘c6
9... ♕f6 is also possible. If then 10 0-0-0 ♘c6 play transposes to a position I didn’t feel like playing during the game. It is probably best for White to play 10 ♘d5 ♗xd5 11 ed, whilst 10 d5 ♗c8 11 ♘b5 also deserves attention.
10
♘d5
As already mentioned 10 0-0-0 ♕f6 didn’t appeal to me as 11 e5 de 12 d5 ♗f5 13 ♘e4 ♗xe4 14 ♕xe4 ♘d4 is good for Black (15 c3 ♕f5). 11 ♘d5 might be playable but if I’m going to do this I prefer the black queen on d8 whilst 11 ♘ce2 leaves White extremely cramped.

At this stage, I was not altogether delighted with my position, but by now it was too late to change track.
15
...
♕b8?
Black assumed that the ensuing endgame was very favourable for him and didn’t seriously examine 15 ... ♖b8!. This seems to give him a winning attack after ♕xa6 ♖xb2 and now:
(a) 17 ♗c3 ♖b6 18 ♕a4+ ♔f8 19 d5 ♘f5! and White’s days are numbered.
(b) 17 ♗xf4 ♖xe2+ 18 ♗xe2 ♗xf4 19 ♖f1 ♗g3+ 20 ♔d1 ♘e4 21 ♕b5+ c6 22 ♕h5 ♘f2+ 23 ♔c2 ♘g6 24 ♗xg4 0-0 when Black has a dangerous attack in addition to his material advantage.
(c) 17 0-0-0 ♖xd2 18 ♖xd2 f3 with a very strong attack.
(d) 17 ♗cl. This is the critical line, as if the rook retreats White will have no problems, e.g. 17... ♖b6 18 ♕a4+ ♔f8 19 ♘xf4 with the idea of ♘e6+. However, Black has a very strong reply, 17... ♕b8!!, after which White seems defenceless:
(d1) 18 ♗xb2 ♕xb2 19 ♕b5+ ♕xb5 20 cb ♘ed5. Despite being the exchange ahead White is completely lost. It is impossible for him to untangle his pieces and he is also in grave danger of getting mated. His only trump is the passed a-pawn, but this is not far enough advanced to cause any problems, e.g. 21 a4 ♘e4 22 a5 f3!, with the threat of 23... ♗d2+ 24 ♔d1 ♘e3 mate.
(d2) 18 ♕a4+ ♔f8 19 ♘xf4 ♖b1 20 ♖xb1 ♕xb1 winning, as 21 ♕d1 loses to... ♗xf4 and... ♕e4+.
(d3) 18 ♕a3 ♖b1 19 ♖xb1 ♕xb1 20 ♕a8+ ♔d7 21 ♕xh8 (22).
White has won a rook, but his forces are totally disjointed and Black’s next move is the nail in the coffin: 21... ♘eg8! (21... ♘e4 22 ♕xh7 and it is unclear if Black has anything better than perpetual check with 22... ♕b4+ and 23... ♕a4+; 22... f3 is dangerous, but White should escape with 23 ♕xh6 f2+ 24 ♔d1 ♕d3+ 25 ♗d2 ♘f5 26 ♕f4 ♘xd4 27 ♕xe4! ♕xe4 28 ♘xd4 ♕xd4 29 h5). After 21 ... ♘eg8 White’s queen will take no further part in the game, e.g.
(d31) 22 ♔f2 g3+ 23 ♔g1 ♕g6 24 ♘xf4 (24 h5 ♕g4 is no better) 24... ♕c2! 25 ♘e2 ♕xc1!! 26 ♘xg3 ♕e3+ 27 ♔h2 ♗f4 28 ♕g7 ♘h5 29 ♕xf7+ ♘e7 and mate follows.
(d32) 22 h5 with the idea of preventing... ♕g6 meets with a brilliant refutation: 22... ♔e7!! and White is powerless to prevent... ♔f8 and... ♗g7.

Black should instead play 18... ♘g6 immediately and then if 19 ♘xg6 hg 20 0-0-0 Black has a slightly better ending. Better is 19 ♘d3! with a roughly level game, e.g. 19... h5 20 0-0-0 0-0 21 ♘f2! ♖fe8 22 g3!? ♖e3 23 ♖d3 ♖be8 24 ♘d1.

(This seems more logical to me than Makarichev’s suggestion in New in Chess of ♕d2 followed by 0-0-0. Black is weak on the f-file so the good old-fashioned recipe is called for: bishop on c4, rook on f1. An eventual ♘d5 may also cause problems). Black can try:
(a) 11... ♘c6 12 0-0 ♕xd4+ 13 ♕xd4 ♘xd4 14 ♘fd5 ♘xd5 15 ♘xd5 ♘e6 16 ♘f6+ ♔e7 17 ♖ael and White has more than enough compensation.

(b) 13 ♗c3 ♕xe4 14 ♕xe4 ♘xe4 15 ♗xh8 ♘g3 16 ♖h2, (For the exchange Black has two pawns and everything will now hinge on whether the f- and g-pawns are strong or weak). 16... ♗e6 looks like Black’s best (If 16... ♘f5 17 0-0-0 ♗xh4? 18 ♖xh4 ♘xh4 19 ♗f6; Black could also try to lock the bishop out of the game with 16... f6, but he would then run into trouble along the a2-g8 diagonal and on the e-file. However, 16... ♗d6 17 0-0-0 ♗c7 is unclear) 17 ♗e5 (After other moves Black has good compensation, e.g. 17 ♘e2 ♘xf1 18 ♔xf1 ♗d6; or 17 0-0-0 ♘d7) 17... ♘xf1! 18 ♔xf1 ♗c4+ 19 ♔el ♗c5! (Black is hanging onto his pawn by tactical resouces) 20 ♘e2 (20 0-0-0 ♗e3+ 21 ♔b1 ♘d7 or 20 ♖h1 ♗e3 are good for Black) 20 ... g3! (20... f3 is not so good after 21 gf gf 22 ♘d4 ♘d7 23 ♘xf3! ♘xe5 24 ♘xe5 ♗d6 25 ♖g2!) 21 ♖h3 (21 ♖h1 f3! 22 gf g2 with advantage to Black) 21... ♗f2+ 22 ♔f1 (22 ♔d1 f3 is strong) 22... ♗e3 23 ♔e1 and Black has the pleasant choice between 23... ♗xe2 or 23... ♗e6.
So, instead of 8 e5?!, 8 ♘ge2. Now Black can play 8 ♗h6, transposing to Gallagher - Jackson (and we don’t mind that!), or push with 8... f3 9 ♘g3 f2+ 10 ♔e2 (OK, we’ve had to move our king, but take a look at Black’s position. What a mess!) 10... b6 doesn’t help: 11 ♗g5 ♗a6+ 12 ♔e3 ♗h6 13♕xg4.
8
♘ge2
♗h6
8... f3, as usual, doesn’t solve Black’s problems: 9 ♘f4 (9 ♘g3 also looks good) 9... fg (Black should have tried 9... f2+ 10 ♔xf2 g3+, regardless of whether it’s good or not) 10 ♗xg2 c6 11 e5! with a crushing attack in Bangiev - Mayr, Corr. 1986.
9
♕d2
This strange move is seen from time to time in the King’s Gambit, normally when White is in a hurry to retrieve the gambit pawn. However, in this position it doesn’t seem to work too well. Bangiev also considers 9 g3!? fg! 10 ♗xh6 ♕xh6 (10... ♕f2+ 11 ♔d2 g2 12 ♗xg2 ♕xg2 13 ♗g5 with active play for the pawn) 11 ♕d2 ♕xd2+ 12 ♔xd2 ♘bc6 13 ♗g2♗d7 14 ♖af1 with a distinct initiative compensating for the lost material.
I think White would do best here to play 9 ♕d3 with the usual idea of ♗d2 and 0-0-0.
9
...
♘bc6!
Black puts d4 under immediate pressure. 9... ♗d7 is rather passive; Planinc - Portisch, Ljubljana 1973 continued: 10 g3 ♘bc6 (10... fg? 11 ♕xh6 is good for White) 11 gf 0-0-0 12 ♗g2 ♕g7 13 d5 ♘e5 14 ♕e3 ♔b8 15 ♕f2 with the better game for White.
10
g3?! (28)
This recommendation of ECO is not good. Instead, White should take advantage of the one drawback created by Black’s ninth move (i.e. the inability to defend c7 sensibly) and play 10 ♘b5. After 10... ♔d8 11 d5 (Bangiev considers the complications after 11 e5 ♕f5 12 ed ♘d5 13 dc+ ♔d7 to be in White’s favour, but he didn’t suggest a way to beat off the black attack. I certainly can’t see anything resembling a White advantage) 11... ♘e5 12 ♘xf4 a6! 13 ♘d4 g3 with an unclear position. The game Gallagher - G. Flear, Lenk 1992 continued 14 ♘de2 ♖g8 15 ♕d4 ♗g4 16 ♗e3 ♗xe2 17 ♘xe2 ♘f 3+! ? 18 gf ♕xf3 19 ♗xh6 ♕xh1 20 ♗g5! g2 21 ♔f2! ♖xg5! 22 hg gf=♕+ 23 ♖xf1 ♕h4+ 25 ♘g3 ♔d7 26 ♕f6 ♖g8 27 ♖h1 ♕xg5 28 ♕xg5 ♖xg5 29 ♖xh7 ♔e8 ½-½.

♗g7
The bishop switches diagonals in order to assist the attack on d4, whilst at the same time unpinning itself. To avoid losing a pawn, White is forced into the extremely ugly...

Well, it turns out he loses one anyway as 12 dc ♕f2+ followed by... g2 is disastrous.

The full effects of 11 d5 are shown as Black completely dominates the centre.

16 ♕d3 is probably a slight improvement although after 16... f5! 17 ♖f1 fe 18 ♖xf3 (or 18 ♘xe4 ♕xd3) 18... ed 19 ♖xd3 ♘f5, Black stands clearly better.
