Russia ?, 1910

1.e4 e5 2.f4
The veritable Kings Gambit. Still in the early 1900s, as in the previous century, almost a must for White to play it and Black to accept it.

2...exf4 3.Nf3 Be7
The Cunningham Defence, one of Black's relatively unexplored replies to the Kings Gambit, and one often favoured when playing the Black pieces by top GMs such as Hebden who often played the KG as White.

By far White's most common move here. However, GM Shaw suggests it may not neccessarily be White's best and also examines the complexities resulting from White developing the other knight first [4.Nc3 Bh4+ (or 4...Nf6 5.d4 d5 6.exd5 Nxd5 ) 5.Ke2 ; On the other-hand KG expert Thomas Johansson also examines the idea introduced in the 1950s by Santasiere of 4.Be2 This is a move relatively rarely played but one which has several advantages over Bc4, for instance, nullifying the pin should Black play Bg4.; The slightly eccentric 4.h4 is another White option that has been played on occasion and has the advantage of preventing one of Black's key ideas in the Cunningham which is the possibly irksome bishop check on h4.]

[4...Nf6 is the main alternative played about as often as the bishop check. An example,by Correspondence Chess against an IM, is given as the third game of this Brevities 15 article.]

The more "gung-ho" method (aptly termed the Wild Cunningham by Du Mont and Tartakower) where White sacrifices more material for time and development compared to White side-stepping the check with Kf1. Surprsingly, both moves were played often in the mid-1800s but more recent games tend to favour the king move more so. One example is [5.Kf1 Short-Kasparov, London Rapid Match 1993 and another, slightly lower level game, is annotated as the second game of this Brevities article.]

5...fxg3 6.0-0 gxh2+ 7.Kh1 d5
Quite the correct idea in these sort of Open Games. Black returns material to aid development and/or blunt the action of the Bc4. [7...Nh6 is another frequent Black choice which has the laudable aim of defending f7. However, the move leaves the knight prone to Bxh6 as the following examples indicate 8.d4 0-0 (instead 8...Qe7 led to a crushing win for the 8 year old Reshevsky in a simultaneous display he gave in Berlin 1920: 9.Bxh6 gxh6 10.Ne5 Bf6 11.Qh5 Rf8 12.Nxf7 Qxe4+ 13.Kxh2 Qxc2+ 14.Kg3 Bh4+ 15.Qxh4 Qxc4 16.Qd8# ) 9.Bxh6 gxh6 10.Ne5 has occurred a few times, for instance in Gauche-Medeiros, 1st Ponta Grossa open Brazil 2017, when White soon won following 10...d5 11.Nxf7 Rxf7 12.Bxd5 Kh8 13.Rxf7 Nc6 14.Qf3 Bd7 15.Bxc6 bxc6 16.d5 Kg8 17.Nc3 Be8 18.Rf8+ Kg7 19.Rf1 Rb8 20.Rg8+ ; 7...Bg3 is an odd move pointed out by GM Shaw when White has good compensation for the increasing material sacrificed after 8.Bxf7+ Kxf7 9.Ng5+ (but not 9.Ne5+ when Back ended up with a winning position via 9...Ke8 10.Qh5+ g6 11.Nxg6 Nf6 12.Rxf6 Qxf6 13.Nxh8+ Kf8 14.Qe2 Nc6 Feng-Paluch, LSS BI e-mail 2010.) 9...Ke8 10.d4 etc.]

[Instead 8.Bxd5 allows Black to instigate exchanges and achieve a good position with 8...Nf6 9.Nxh4 (9.Bxf7+ looks interesting but is better for Black after 9...Kxf7 10.Nxh4 Rf8 Wall-Magee, corr 1980.) 9...Nxd5 10.exd5 Qxh4 11.Re1+ (11.Qe1+ and; 11.Qe2+ are slightly more promising options for White to stay in the game.) 11...Kd8 12.Re3 Re8-+ De Bortoli-Popa, Verona 1997.]

Black has a number of other playable options but sometimes falls off the cliff in practical play: [8...Nh6 9.d4 Nf5 10.Qe2+ Kf8 11.Bf4 Bg3 12.Qd2-/+ Berger-Ruetsch, Darmstadt Heinerfestpokal opn 1994.; 8...Bg4 9.d6 Qxd6 10.Qe2+ Kd8 11.Bxf7-/+ Neulinger Jagode-Lichtmannecker, Nord Bayern op Pocking 2001 but again rapidly continued to a White win after 11...Nf6 12.Nc3 c6 13.Ne4 Nxe4 14.Qxe4 Bxf3+ 15.Rxf3 Bf6 16.Rd3 ; 8...Bh3 9.Qe2+ Be7 10.Re1 Bg4 11.Nc3 Nf6 12.d4 a6 13.Bf4-/+ Molnar-Cabrijan, Rijeka Liburnija open 2014.]

9.d4 Ne7
Oddly Black has played up to here as recommended by GM Shaw over a centuary later but soon goes astray. Another game went instead [9...Nd7 10.Bb3 Nb6 11.c4 Bh3 12.Re1+ Ne7 13.Ne5 when White has some play for the 2 pawns deficiency: Sternik-Hervas, IECC M e-mail 2002.]

Setting a trap into which Black falls. Alternatively [10.Nc3 simply developing rapidly gives an unclear game.]

Possibly not so much underestimating the sacrifice on f7 but more the possibility to follow up with sacrifices on f6.

Not only exposing the Black king but allowing the Bc4 to spring to life, which in conjunction with the weak g6 square, is fatal for Black.

[Of course if 11...Qd7 simply 12.Nxh8+- when Black is unable to win the Nh8 as some compensation for the lost rook.]

12.d6+ Kf8
[Alternatives are not any better for Black: 12...Be6 13.Qh5+ g6 (13...Ng6 14.Bxe6+ Kxe6 15.Qxg6 when the Black will be exposed to a devastating attack stuck in the middle of the board.) 14.Rxf6+ Kxf6 15.Qe5+ Kf7 16.Bxe6+ Kf8 17.Qxh8+ Ng8 18.Qxg8# ; 12...Kg6 is also hardly appealing for Black as White may play 13.dxe7 Qxe7 14.Qd3+ Kh5 15.Nc3 with Ne2 and Nf4 or g3 to follow when the marooned king will expire.; and if 12...Ke8 13.dxe7 Qd6 14.Qh5+ Kxe7 15.Bf4 when again the king will survive just a few moves in its vulnerable central status.]

13.Qh5 Qe8
There is nothing better but this allows a very attractive White finish.

14.Rxf6+ gxf6 15.Qxh6+ Rxh6 16.Bxh6#
An unusual queen sac and 2 bishop mate. 1-0
