GM#1 vs you: Wing gambit bombs, BC & history: 1

 GM#1 vs you: Wing gambit bombs, BC & history1  

   

(by Yury V. Bukayev) 

 

 

In this analytical  investigation we’ll consider the practical problem: how to play against WCC, World Standard and Rapid Chess #1 GM Magnus Carlsen or against World Blitz Chess #1 GM Hikaru Nakamura if he has White pieces and chooses 1.e4 e5 2.h3?. And we’ll consider the history of this problem, we’ll make our new view on the wide circle of problems of chess opening theory and history. This future great maestro Paul Morphy’s weak 2nd move (Morphy – NN, New Orleans, 1848) is normal for them in some casesthe chess world knows about the scandalous grandmaster draw in the game Carlsen – Nakamura, Magnus Carlsen Invitational’ tournament, 2021, March 15 (1.e4 e5 2.Ke2?? Ke7?? 3.Ke1 Ke8 4.Ke2?? Ke7?? etc., 1/2-1/2), and about Mr. Nakamura’s practice of 2.Ke2??.  

While modern commentators argue about joke names of the joke opening 1.e4 e5 2.Ke2?? - “Bongcloud attack in C20, or “Boungcloud attackor “Bongcloud opening”, or “BC (opening), etc. - we suggest to call it also e4e5 King’s joke opening” or “the Vidmar joke opening” according to outstanding maestro GM Prof. Milan Vidmar’s published memoirs (“Goldene Schachzeiten: Erinnerungen”, Berlin, Walter De Gruyter & Co., 1961, p.227-228, and we can’t exclude that this story was published originally earlier than 60 years ago) about his funny win as White after 1.e4 e5 2.Ke2??. It is known that this descripted event isn’t a fake in contrast with several other “events” which can be found in other sources including Andrew Fabbro’s fake-based section “History” of his parody work “Winning With the Bongcloud: A Complete Repertoire for White (2010) on the BC family, or the KJO family, as we suggest to call it (in fact, this family consists of all possible opening sequences where White makes a joke King’s move on the 2nd move and of the certain kind of ones where White makes it on the 3rd move). The latest of printed sources (which retells this Prof. Vidmar’s story) we could find is Peter Koehler’s book Das grosse Schach-Allerlei: VerwegenesVerrücktes und Verkorkstes auf 64 Feldern” (GöttingenVerlag Die Werkstatt GmbH2016). Thus, its part “Düpiert” (“The Duped”) tells (p.11-12):  

 Eine Pleite besonderer Art erlebte der slowenische Großmeister Milan Vidmarals er sich – es war in den 1920er Jahren – in einem Kaffeehaus in seiner Heimatstadt Ljubljana zum Zeitunglesen niedergesetzt hatte. Am Nebentisch war eine Schachpartie im Gang, doch ein Blick genügte ihm, um festzustellendass es sich um zwei Patzer* [*German slang: amateur chess players who played the game without a skill – Note by Yu.B.] handelteEnttäuscht wandte er sich wieder seiner Lektüre zuals plötzlich einer der beiden aufstand und sich verabschiedete. Der andere blickte sich um, und weil er Vidmars Interesse bemerkt hattefragte er ihnob er Schach spieleVidmar gab zumit dem Brettspiel einigermaßen vertraut zu sein<…> Vidmar beschlosssich Ã¼ber den Schwachmaten lustig zu machen: <…> 1. e4 e5 2. Ke2 Sf6 3. Kd3 Sc6, und nach dem vollends tollkühnen 4. Kc4 provozierte Vidmar seinen Gegner zusätzlichindem er auf den ungedeckten e-Bauern hinwies und verlautbartejetzt Gambit spielen zu wollen. „Die Antwort war verblüffend“, schreibt Vidmar in seinem Erinnerungsbuch Goldene Schachzeiten: „Mit einer energischen mähenden Bewegung seiner Rechten rasierte mein Gegner das Schachbrett, so dass die Figuren fast wegflogen, und erklärte mit schlecht zurückgehaltener Wut: ‚Mit einem solchen Stümper spiele ich nicht!‘  .  

Thus, we can see that this unique won (abandoned) “super handicap” game which has 4 moves only is approximately 100 years old. We don’t know what real goal has Prof. Vidmar had here, and we can’t exclude that he has tried to cause opponent’s abandonment in fact. But ware thankful to Rick Kennedy who helped us kindly to find the pages of Prof. Vidmar’s book, to Mr. Koehler, to everyone who also told this story, and we hope that future chess literature will not forget this story if it writes about Bongcloud attack in C20, about above “immortal game Carlsen - Nakamura with Double Bongcloud. But Prof. Vidmar’s game is important for history, not for future practice of handicap games. Below we’ll consider also our new serious analysis and the psychology of a solid chess player” for Black for the possible treaty initial position (A02) 1.f4 Na6? 2.Kf2? (f4Na6 King’s joke opening”) in your possible game with BC against WCC Magnus Carlsenwe’ll see that White (who stands worse after the 2nd move) can stand slightly better after the 4th move here in result of one Black’s chess mistake based on this “psychology”. 

Now we should return to 1.e4 e5 2.h3?In this situation after the symmetrical response 2…h6?! AN (We don’t write the sign “?” here, because after the exact Black’s play Black can keep an equal position everywhere. For example, if White plays 3.Nf3 Nc6 4.Bc4, then you should go this way: 4…Nf6! 5.Nc3 Bc5! = , not the fork trick way of the Italian variation of Four Knights Game 5…Ne4 6.Ne4 d5 7.Bd3 de 8.Be4 Bd6! 9.Bc6! bc 10.d4 ed 11.Nd4 (or 11.Qd4!? 0-0 12.Be3) 11…0-0 12.Be3 or 12.Ne2: White stands slightly better everywhere, most probably.) you have a large temptation for an analogous “grandmaster draw without your efforts and for a world scandalous fame: 3.Rh2?? (for example, he’ll choose this scandalous way) 3…Rh7?? 4.Rh1? Rh8?! 5.Rh2?? Rh7?? etc., 1/2-1/2. If tournament rules permit to write some words to your opponent, then you have also the alternative possibility – a memorable renunciation of this White’s present by 2…h6?! with your following words, for example: “Thank you, but I would like to not receive such presents by design from you in future, so 2…h6 is my polite diplomatic renunciation only. In any case, White can start to play strongly after 2…h6?!. After 3.Nf3 Nc6 4.Bc4 be attentive, because after possible 4…Bc5 (C50) our new strong Wing gambit 5.b4! is what he wants: 5…Bb4 6.c3 Ba5 7.d4! d6 (7…ed 8.0-0 d6 9.cd Bb6 10.d5!) 8.de de? 9.Bf7!! Kf7 10.Ne5! with a win..  

Instead of these memorable possibilities, you can play strongly everywhere, for example: 2…Nf6! 3.Nc3 Bc5! (C26). If he plays here 4.Bc4, then the strong Wing gambit 4…b5! is what you want. And it will be also memorable. It’s easily to see that the 1st of these two gambits is a new part of the known opening family of strong Wing gambits. This family contains C50 Evans-Bukayev gambits and C26 gambits where Black uses the same idea (the most important of such other gambits in Vienna Game C26 is our invention in the Mengarini variation: 1.e4 e5 2.a3? Nf6! 3.Nc3 Bc5 4.Bc4 d6 5.h3 b5! AN (the Evans-Bukayev gambit reversed), it’s much more important than the same with 4…0-0 5.h3? b5 AN because Black has other simple ways to a win too). After 1.e4 e5 2.h3? Nf6! 3.Nc3 Bc5! your opponent should play 4.Nf3! Nc6 5.Bc4! d6 6.a3! AN, and White keeps an equal position6…Be6 7.Be2!, or 7.Ba2!?, or 7.Qe2!?.  

We’ll prove why this Black’s gambit (4…b5!) is really strong. There is a known game (Mead – Morphy, 1857) where this gambit appeared: 1.h3 e5 2.e4 Nf6 3.Nc3 Bc5 4.Bc4 b5 5.Bb5 c6 6.Ba4 0-0 7.Nge2 d5 8.ed cd 9.d4 ed 10.Nd4 Qb6 etc. (0:1). We can see the good way after 7.d3! (in fact, Mr. Mead’s move 7.Nge2! is good too, because 7…d5! 8.d3! AN is a good way too) 7…d5!: 

8.Nge2! AN de (8…d4?! 9.Nb1) 9.de Qd1 (9…Qa5 10.0-0 Ba6 11.Bb3. White stands better) 10.Nd1 Ne4 11.f3! (11.Be3 Bb6! with the idea 12…Nc5!) 11…Nf6 12.Be3. White stands better. 

That is why the great maestro Paul Morphy was lucky in this game. We can see that our move 6…d5! AN is much better than Mr. Morphy’s move 6…0-0. Thus, after 6…d5! AN 7.d3 (7.ed is also possible) 7…de 8.de? Bf2!! 9.Kf2 Ne4! Black wins (analogously to White’s winning way after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.d3 h6 5.b4! (the Evans-Bukayev gambit) 5…Bb4 6.c3 Ba5 7.d4! d6 (7…ed 8.0-0 d6 9.cd Bb6 10.d5!) 8.de de? 9.Bf7!! Kf7 10.Ne5!). [Addition: It maybe everyone will call this not named gambit 4…b5! as the Morphy-Bukayev gambit” and call its above variation 6…d5! as “the Bukayev first attack”. We agree to these names.]  

Analogously, in the Italian Game (C50) after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.d3 h6 5.b4! Bb4 6.c3 Ba5 7.0-0 Black should play 7…d6 (or 7…Nge7 AN 8.d4 d6!) 8.d4 Nge7! AN 9.de de etc. with Black’s advantage 

The above position 1.e4 e5 2.h3? (or 1.h3? (it was named later as ‘the Clemenz opening’) 1…e5 2.e4) was played by Mr. Morphy also as White, but only once. It was his early game against the unknown opponent. Our analysis of first moves of this game (Morphy – NN, New Orleans, 1848) shows that the future great maestro was lucky here too: 1.e4 e5 2.h3? d5 3.ed Bc5 [The way with 2…d5, 3…Bc5 isn’very bad, although modern theory knows a lot of more strong ways, of course.] 4.Bc4? [4.Nf3!] 4…c6? [4…Bf2! 5.Kf2 Qh4 6.g3 Qc4 7.Nc3 (7.Nf3 Ne7! AN 8.Nc3 e4! with the advantage) 7…Qc5! AN 8.Kg2 Ne7!? with the advantage. {That is why White should play in the Baron von der Lasa gambit by the following way: 1.e4 e5 2.d4 ed 3.Bc4 Bc5? 4.Bf7! Kf7 5.Qh5 g6 6.Qc5 Nf6 7.Ne2! AN with the advantage; 6…Nc6 7.Qc4! AN Kg7 8.Ne2!? with the advantage.}] etc. (1:0). When Valery Golshev (the author of the classificator of chess opening sequences ‘ECO-gamma’) informed us about this game in the database, it was difficult for us to answer him surely why Mr. Morphy played here 2.h3, in my opinion. Thus, our early main version was the following: probably 11-year P.Morphy solved to give a handicap (by wasting a move) after the formation of his favourite position (1.e4 e5) only. But now our main version is the following: probably 11-year P.Morphy made his weak experiment, so it wasn’t a handicap. That is why we shouldn’t suggest to call it as “the Morphy’s Handicap opening”, we suggest to call it as “the Morphy’s Luck opening”: this name reflects our above analyses of both Paul Morphy’s games. 

Now we can return to your possible game against WCC GM M.Carlsen with the above treaty initial position of the Bongcloud opening in A02 (1.f4 Na6? 2.Kf2?) where this treaty will be Mr. Carlsen’s handicap. If you have a “psychology of a solid chess player” then you’ll try to choose only “solid” moves. Thus, you’ll choose 2…Nc5!? AN because such “psychology” creates these thoughts: “If I keep my Knight on a6, then it can seem to be “not solid” to some commentators (such as the outstanding maestro of the past Dr. Siegbert Tarrasch). Further, 2…Nb8 (it isn’t also beautiful) and 2…Nb4? are not solid because I’m standing better now, only 2…Nc5 is solid here for each commentator”. Mr. Carlsen’s response will be probably the aggressive move 3.Nc3!? instead of the most careful 3.d3. Here your “psychology of a solid chess player” can create your new thoughts: “My position will not be “solid” probably for some commentators if my 3rd move isn’t an aggressive, natural and standard move 3…d5. Thus, you’ll choose it, but it will be your large chess mistake, although it keeps a material equality in the main variation3…d5? 4.d4! (White stands slightly better.) 4…Ne4! [4…Ne6?? 5.f5 +-; 4…Nd7?? 5.Nd5 (White stands better.); 4…Na6 5.e4! de (5…e6 6.Ba6, and White stands better.) 6.Ba6 ba 7.Ne4 (White stands better.); 4…e5 5.fe (5.dc Bc5 with a sharp position where White wins after a complicated fight) 5…Ne4 6.Ne4 de (White stands better.)5.Ne4! de! 6.e3!, and White stands slightly better (although the advantage is very small). That is why you should be attentive always, even in the BC (KJO) opening family. 

In result, we should say that if GM#1 plays 2.h3? against you (after 1.e4 e5), then your choice of one of the above ways can make your game memorable

Jerome Gambit: Hard Working Queen


Along with the Bishop sacrifice at f7, the active play of White's Queen typifies the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). In the following game it looks at one point that the Queen is trying to win the game all by herself. She finally relents and allows some assistance - but that only means that White wins even faster.


Wall, Bill - Terenure

PlayChess.com, 2021 


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5. Nxe5+ Nxe5 6. d4 Bd6 


At first glance this looks like a reasonable response, planning to return a Knight for a pawn. Yet, there has to be some mistake in that thinking, if only because of the 160 games in The Database with this position, White has scored 72%.

Furthermore, before this game Bill was 25 - 0 with White.

As we shall see, the simpler 6...Bxd4 was also safer. 

7.dxe5 Bxe5 

For an even game, the Bishop needed to go to e7, either directly or after 7...Bb4+. "An even game" does not sound all that bad, until you consider that only a couple of moves ago, Black was two pieces up.

8.Qd5+ Kf6 

Not wanting to give up any more material, but this only makes matters worse.

9.f4 Ne7 10.Qxe5+ Kf7 11.O-O


Thoughtful. White's Queen has done well to recover the sacrificed material, but she will need help as the game goes on. White safeguards his King and puts his Rook on the same file as Black's King.

11...Ng6 12.Qd5+ Ke8 13.f5 Ne7 14.Qd4 d6 15.Qxg7 


Okay, I admit, the Queen continues the attack on her own.

15...Rg8 16.Qxh7 Bd7 17.Nc3 

Aha!

17...Rf8 18.Bg5 


Aha!

18...Rf7 19.Qh8+ Rf8 20.Qh5+ Rf7 21.Nd5 c6 22.Nf6+ Kf8 23.Qh8+ Black resigned

Jerome Gambit: Well-Traveled King



The following lengthy Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game is a bit much to wrap your head around. It was played at bullet speed - 1 minute, plus 1 second increment - and features a well-traveled enemy King who makes over 1/3 of the moves played in the game.

(For the record, the longest Jerome Gambit game that I have in The Database is 158 moves. Of course it was played by 2 computer programs. But there is also a 157-move game played by 2 humans.)


boltonbailey - Jonathan_Nobleman

1 1 bullet, Chess.com, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 


7.Qf5+ Kd6 8.Nc3 Qf6 9.Qxf6+ Nxf6 


Okay, so far it looks like Black is winning (he is), but at this time control anything can happen. Soon, it does.

10.d3 Bd4 

Looking to break up White's Queenside, but this is too much of a static approach.

11.Nb5+ Kc5 12.a4 a6 13.b4+ Kxb4 

It is possible to get careless, even (especially) when up a couple of pieces. White is probably a little bit better now.

14.Nxd4 

Very reasonable, and the idea behind White's pawn sacrifice. (If he had more time to reflect, he might have found 14.Rb1+ Kc5 15.Ba3+ Kb6 16.a5+ Kxa5 17.Nxd4 d6 18.Bb4+ Kb6 19.Bxd6+ Ka7 20.Bxe5 which would have left him a Rook ahead.)  

14...Kc3 15.Ne2+ Kb4 

Like it or not, Black had to move further into danger and play 15...Kxc2, because White's Rook can now come to b1 with check, to be followed in due course by mate

16.Bd2+ Kc5 17.Bc3 Kc6 18.Bxe5 d6 19.Nd4+ Kd7 20.Bxf6 gxf6


The Black King has returned home, with his position somewhat worse for wear.

21.O-O c5 22.Nf5 Ke6 23.d4 cxd4 24.Nxd4+ Kf7 25.Nf5 Bxf5 26.exf5

With the clock ticking rapidly and always possible to take a friendly turn, neither player is looking at a draw. Even when the balance of the game shifts, there is no practical reason to resign before being checkmated.

26...h5 27.h3 h4 28.Rfe1 Rad8 29.Re4 Rh5 30.Rf4 d5 31.Rd1 d4 32.Rdxd4 Rxd4 33.Rxd4 Rxf5 34.Rxh4 Ke6 35.Rd4 b5 36.axb5 axb5 

White's Kingside pawn majority gives him a clear advantage.

37.f3 Rc5 38.Rd2 Kf5 39.Kf2 b4 40.g3 Kg6 41.Ke3 Re5+ 42.Kf4 Rf5+ 43.Kg4 Rg5+ 44.Kf4 Rf5+ 45.Ke3 Re5+ 46.Kf2 


No wish to allow the draw by repetition. (Translation: not feeling the time pressure.)

46...Kf5 47.Rd4 Rb5 48.g4+ Kg6 49.Ke3 f5 50.Kd3 fxg4 51.hxg4 Kg5 


52.Kc4 Rb8 53.Kb3 Rc8 54.Rd2 Rb8 55.Rd4 Rc8 56.Rxb4 Re8 57.Rc4 Re3+ 58.Rc3 Re5 59.Rd3 Re8 60.Kc3 Rc8+ 61.Kd2 Re8


The winning plan is clear.

62.c3 Kf4 63.c4 Rc8 64.Rc3 Rd8+ 65.Kc2 Kg3 66.c5 Kf2 67.c6 Ke2 68.c7 Rd2+ 69.Kb3 Rd1 70.Rc2+ Kxf3 71.c8=Q 


See the note to White's 25th move.

71...Rb1+ 72.Kc3 Rb6 73.Qf5+ Kg3 74.Qe5+ Kh4 75.Qe1+ Kg5 76.Rg2 Rc6+ 77.Kd3 Rd6+ 78.Kc4 Rc6+ 79.Kd5 Rc8 80.Qe7+ Kg6 81.Qe6+ Kg7 82.Qxc8 Kg6 83.Qf5+ Kg7 84.Rh2 Kg8 85.Rh5 Kg7 86.Rg5+ Kh6 87.Qg6 checkmate

Amazing.

Another Paulsen



The following game - in Hans Renette's Louis Paulson A Chess Biography with 719 Games (2019) - features a variation of the Scotch Gambit which should look familiar to Jerome Gambit players.

Fischer played blindfold. Black was played by Louis Paulsen's brother Wilfried.


Fischer, E. - Paulsen, W.

blindfold exhibition, Detmold, 1855


1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bc5 5.Ng5 Nh6 6.Nxf7 Nxf7 7.Bxf7+ Kxf7

The Sarratt or Vitzthum Attack, a possible fore-runner to the Jerome Gambit. See "A Bridge To... Somewhere?", "Another Distant Relative?", "The Sarratt Attack", "Another look at the Sarratt Attack" and "Sarrat Attack: No Way A World Champion...".

8.Qh5+ g6 9.Qxc5 

The "nudge" 9.Qd5+ followed by the capture of the Bishop (e.g. Steinkhuler - Blackburne, Manchester, 1861) is probably not as good here.

9...d6 10.Qb5 Re8 11.Qd3 d5 

12.f3

White needed to castle here, even though that would allow 12...dxe5, with advantage to Black.

12...dxe4 13.fxe4 Qh4+ 

14.g3 Rxe4+ 15.Kf2 Qe7 

He could have played 15...Qf6+ 16.Bf4 Re3 with clear advantage.

Possibly both players overlooked the fact that the text could be met by 16.Bg5, winning the exchange, although Black would still be better. 

16.Nd2 Re3 17.Qf1 


17...Bh3 18.Qc4+ 

Capturing the Bishop would lead to checkmate - but so does the text.

18...Kg7 19.Nf3 Rxf3+ 20.Kxf3 Rf8+ 21.Bf4 Qe3 checkmate

An Early Lewis Gambit



I have been making my way through Louis Paulson A Chess Biography with 719 Games (2019) by  Hans Renette and discovered an early example of the Lewis Gambit - one of the openings that may have been an inspiration to Alonzo Wheeler Jerome to develop his gambit.


Paulsen, Louis - King, J. S.

offhand game, Pittsburgh, 1858

 1.e4 e5 2.Bc4 Bc5 3.d4 exd4 

The Lewis Gambit. The position can also arise from the Van der Lasa Gambit 1.e4 e5 2.d4 exd4 3.Bc4 Bc5

The earliest example I have found of the Lewis Gambit was played by Cochrane against Staunton in two of their match games in 1841. Both times Staunton responded with the stronger 3...Bxd4.

4.Bxf7+ Kxf7 5.Qh5+ g6 6.Qxc5 

Instead, 6.Qd5+ was seen in Blackburne - Evelyn, blindfold exhibition, London, 1862 (1-0, 32). I always find this move humourous, as Jerome later incorporated his own "nudge" into the Jerome Gambit.

6...Nf6 7.Nf3 Re8 8.O-O Nxe4 


9.Ne5+ Kg7 10.Qxd4 Qf6 

11.Bh6+ Kg8 

If 11...Kxh6, 12.Ng4+ will win the Queen.

12. f3 Qxe5 13. Qxe5 Rxe5 14. fxe4 Re8 

Material equality has been reached, but White's superior development gives him a significant advantage.

15.Nc3 c6 16.Rf6 d5 17.Raf1 Nd7 18.Rf7 d4 

19.Rg7+

There was time to rescue the Knight with 19.Ne2, which was even stronger than the text, but White has things figured out.

19...Kh8 20.Rff7

Again, the Knight feels neglected, but White has the game firmly in hand.

20...Nf8 

21.Bg5 Re6 22.Ne2 c5 23.e5 b6 24.Nf4 Rc6 25.Nd5 Bf5 26.Nf6


The Knight is the final piece in the attack.

26...Rxf6 27.Bxf6 Ne6 

and White checkmated in 3 moves, 28.Rxg6+ Ng7 29.Rgxg7 any 30.Rxh7#

Jerome Gambit: Simplicity Can Be Enough



One defensive idea for facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is exchanging Queens - sometimes even at the cost of returning the sacrificed material.

In the following game, Bill's opponent simplifies things - he thinks. The resulting Queenless middlegame / endgame still has many dangers, including, in the end, checkmate.

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+  7.c3 Nc6 


This move has been faced by Jerome Gambit regulars such as chessmanjeff, frizerkaHR, HauntedKnight, jfhumphrey, PasChat, snthor and teterow but it appears that it is the first time Bill has seen it.

Black's method of returning some of the sacrificed material leads to a game where he has a slight edge.

8.cxb4 Nxb4

Quickly returning more.

9. Qb3+ Ke8 10.Qxb4 Qe7 


Holding things together, but Bill is willing to enter a Queenless middlegame a pawn up.

11.Qxe7+ Nxe7 12.Nc3 c6 13.O-O h6 


Black has arranged to avoid the cut-and-slash lines of the Jerome Gambit. He has given White an easy game to play, however - and, again, there is that extra pawn.

14.f4 Rf8 15.Bd2 d6 16.f5 b5 


To fianchetto the Bishop at b7, and possibly undermine the protection of White's center with b5-b4, but there will not be time for that.

17.g4 Bb7 18.e5 dxe5 19.dxe5 Rd8 20.Ne4 Nc8 


An awkward necessity to keep White's Knight out of d6. Possibly Black had anticipated the Knight fork of King and Bishop, and had planned to capture White's Bishop at d2 in return - but, say 20...c5 (an otherwise useful move) 21.Nd6+ and Black's King would be forced to d7, blocking the action of his Rook.

21.f6 g5 

If 21...gxf6 then 22.Bxh6.

22.Bc3 Rf7 23.Rad1 Rd5 24.e6 


Those pesky "Jerome pawns"!

24...Rxd1 25.exf7+ Kxf7 26.Rxd1 Black resigned


White is Rook up, and Komodo 10 says that he has a checkmate in 10 as well.
