Another Krejcik

Recently Geoff Chandler ("greenpawn" at redhotpawn) posted an interesting Krejcik Gambit (1.e4 Nf6 2.Bc4) game at the RedHotPawn website. As that opening's just been touched upon here (see "I want my Jerome Gambit!") I thought I'd share it with readers. It features another relentless King hunt.

Thalassa - MHT
redhotpawn.com, 2004


1.e4 Nf6 2.Bc4 2...Nxe4 3.Bxf7+ Kxf7 4.Qh5+ 4...Kf6

This does not look any wiser than the 4...Ke6 of perrypawnpusher - computer, internet 2009. Better was either 4...Kg8 5.Qd5+ e6 6.Qxe4 d5 or 4...g6 5.Qd5+ e6 6.Qxe4 Bg7.

5.Qf3+ Ke5


Hanging onto the Knight! This is not as dangerous as 5...Kg5 6.Qf7 Nf6 7.d4+ Kf5 8.f3 h5 9.Ne2 h4 10.g4+ hxg3 11.Nxg3 checkmate, but; 5...Kg6 was to be preferred (although White still is better).

6.d4+ Kxd4
7.Ne2+

Interestingly, a bit better was 7.Nc3 Nxc3 8.bxc3+ Ke5 9.Nh3 with a serious attack. It's a position worth looking at.

7...Ke5

A better defence was 7...Kc5, but it's really coming down to which way Black wants to lose.


8.Bf4+ Ke6 9.Nd4+ Kd5
10.Nc3+ Kxd4 11.0-0-0+



White has his choice of checkmates.

11...Kc5 12.Nxe4+

12...Kb6 13.Qb3+ Kc6 14.Qc4+ Kb6 15.Qb4+ Black resigned

"I want my Jerome Gambit!"

The other night I was spending time on my computer, when I decided to go to a website that I'd not visited before, and try out their chess wares. I was having no luck finding an opponent, so I quickly latched onto the resident computer program. I noticed that it was at its default setting, and decided to throw a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) at it.

Bad idea. The silicon warrior did not want to enter a Giuoco Piano, no matter how many times I took the White pieces. Furthermore, it kept insisting that I alternate playing Black. I had to make at least a few moves on defense: once I resigned as my first "move", only to find the computer the next game responding to my 1.e4 with "resigns." Silly computer...

I'd just about given up, and thought about going to bed, when the computer offered to play an Alekhine's Defense. Aha! At least I could go out with Jerome-ish play: I would try the Krejcik Variation!

perrypawnpusher - computer

internet, 2009

1.e4 Nf6 2.Bc4

Sources refer to this as the Krejcik Variation, although the only game I've been able to find by Josef Emil Krejcik, against the player Gottlieb in 1922, went 1.e4 Nf6 2.Bc4 d6 3.Nc3 Nxe4 4.Bxf7+ Kxf7 5.Nxe4 e5 6.Qf3+ Kg8 7.Ng5 Black resigned

2...Nxe4 3.Bxf7+ Kxf7 4.Qh5+



4...Ke6


The best defence for Black is supposed to be 4...Kg8 5.Qd5+ e6 6.Qxe4 d5, which seems quite playable for White to any Jerome Gambit player.







analysis diagram





5.Qg4+ Kd5

The program foolishly holds onto its material. Certainly 5...Kf7 was an option.

6.Qf5+

Going for the quick knockout.

Later, Rybka 3 recommended: 6.Nf3 d6 7.c4+ Kc6 8.Qxe4+ Kd7 9.0-0 Qe8 10.d4 Kd8 11.Qe3 g6 12.Nc3 Bg7 13.Bd2 Rf8 with a White advantage.

There was also the dangerous (for Black) line 6.d3 Kc6 7.Qxe4+ d5 (7...Kc5 8.Be3+ Kd6 (8...Kb5 9.Nc3+ Ka6 10.Qa4#) 9.Bf4+ e5 (9...Kc5 10.Qc4+ Kb6 11.Nc3 a5 12.Be3+ c5 13.Qxc5+ Ka6 14.Qb5#) 10.Bxe5+ Ke7 11.Bxc7+ Kf7 12.Bxd8 +- ) 8.Qa4+ b5 9.Qa5 e6 10.a4 b4 11.Qb5+ Kd6 12.Nf3 Qf6 13.Qxb4+.

6...Kd4


Stubborn to the very end. Less painful was either 6...e5 7.Nf3 d6 8.c4+ Kc6 9.Qxe4+ Kd7 or 6...Kc6 7.Qxe4+ but both involved surrendering the Knight.

7.Nf3+ Kc4 8.Na3+ Kb4 9.Qb5 checkmate

Again and again...


While it is true that the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can have quite an impact when it comes as a surprise, there are some players who are willing to play it again and again against the same opponent, as long as it leads to good results. Mrjoker, for example, has played the Jerome Gambit 16 times against his worthy opponent PhlebasP. Scoring over 80% so far, he is unlikely to give up the opening in their next clash.

Out of a clear sky...

In posts like "I apologize, Jerome Gambit" and "Diagnosis: Misplaced Knight" I have fussed and fumed about the kind of bother that Black's Knights can cause, even in main-line Jerome Gambits (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), so when I saw the following game, I thought I'd share it: for those who defend the Jerome, another annoying idea; and for those who play the Jerome, something to prepare for...

mrjoker - weiran
blitz 2 12, Internet Chess Club, 2008

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6

I have 29 games in my database with this position – almost 2/3 by Louis Morin ("mrjoker") – so, you see, lightning can flash out of a clear sky and strike even the best of the Jerome Gambit Gemeinde.

10.0-0 Ng4 A new move. Where should the Queen go?

Rybka 3.0 suggests the line: 11.Qg3 Rf8 12.Nc3 Nf6 13.d4 Nh5 14.Qe3 Nhf4 15.g3 Nh3+ 16.Kg2 Kf7 17.f4 with a small, but bearable, advantage to Black.

The move White chooses seems thematic (i.e. centralized and on the file opposite the un-castle-able King) in a harmless position.

11.Qe2 Qh4

Suddenly, things are very bad.

12.h3 Nf4 13.Qf3 Ne5

Annoying, yes?

White's response now loses his Queen, but Rybka 3.0 suggests that the "best" move was to give it up anyway with 14.Qxf4.

14.Qc3 Ne2+ White resigned

A lesson worth remembering.

Pandora's Box


I've been digging through my database since I wrote "What Have YOU created lately?" trying to find any kind of creativity in my own play in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). My games are more likely to follow "book" lines (such as there are), waiting for my opponents to get creative.

In the process, I turned up another of my games that I don't think has appeared on this blog. Here we go...

perrypawnpusher - whitepandora
blitz 3 10, FICS, 2008

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6

A defense as old as A.W. Jerome - O.A. Brownson, Iowa, USA, 1875 (1-0, 25)

7.Qd5+

The infamous "nudge".


7...Kf6
This is new.

8.d4

Attacking the enemy Bishop with the pawn and threatening an attack on the d8-h4 diagonal, winning the Queen. Annoyingly, my computers tell me that a) Black is still better and b) the thematic 8.f4 is probably better than the text move.

8...Bb4+ 9.c3 c6

Wow!


Essential was 9...Ke7 10.cxb4 Nf6, keeping the advantage.

Whitepandora was lucky to be playing against me, and not any other member of the Jerome Gambit Gemeinde.

10.Qg5+

Or 10.Bg5 checkmate, take your pick.

Ow!!!


White is still winning with the text move, but a 10-move Jerome Gambit checkmate would have been something to smile about.

10...Ke6 11.Qxd8

With a Queen and two pawns for two pieces, there is no way that this game should last – how many? – 41 moves. I suppose that it is a tribute to my creativity that I find a way.

11...Nf6 12.Qc7 Bd6 13.Qa5

Her Majesty escapes unharmed.

13...Kf7

Instead, 13...Nxe4 grabbed a pawn. Might not help. Couldn't hurt.


14.e5 Re8 15.0-0 Nxe5 16.dxe5 Rxe5

Black has some dangerous-looking development... and it keeps growing.

17.Qa4 b5 18.Qd4

More to the point was 18.Qb3+ Re6 19.Re1, when White will be able to trade off one of the attackers.

18...Rd5 19.Qe3 Bb7

This is getting creepy. One indication of how quickly Black's development has grown was in the line 19...Bxh2+ 20.Kh1 (if 20.Kxh2, 20...Ng4+ winning the Queen) Rh5 21.g3 Bf5 22.Re1 Bxg3+ 23.Kg2 Rh2+ 24.Kxg3 (24.Kg1 Bxf2+) Rh3+ 25.Kf4 Rxe3 26.Rxe3 when the second player has cut the deficit to a Rook for two pawns.


20.Nd2

Planning to get the Knight to its defensive post at f3, but, oddly enough, the best move was to put the Queen there.Now Black has some more hair-raising tactics, such as: 20...Bxh2+ 21.Kh1 Rh5 22. g3 c5+ 23.f3 Bxg3+ 24.Kg2 Nd5 25.Qxc5 (what else?) Nf4+ 26.Kxg3 Ne2+ 27. Kf2 Rxc5 28.Kxe2 Re8+. White has a piece for a (passed) pawn – and is still way behind in development.

20...c5 21.Nf3


Whew!

21...Ng4

Black should have taken his opportunity to develop his last piece with 21...Re8.

22.Qe1 Re8 23.Be3 Rh5

24.h3 Ne5 25.Nxe5+ Rexe5 26.Rd1 Bc7

In the hands of a "spoiler"

With only four games left to complete in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Thematic Tournament at Chessworld, Piratepaul holds a slim .5 point lead (21.0 out of 26 games) over stampyshortlegs (20.5 out of 27 games). All three of their games are against Crusader Rabbit (5.0 out of 25 games), who has secured 14th place, but who clearly can play the role of spoiler. If Crusader Rabbit wins all his games, or loses all his games, Piratepaul will hang onto first place; but the proper distribution of wins, losses and draws could put stampyshortlegs on top. This exciting tournament of 210 games could come down to the final move!

The Bishop's Evans Jerome Gambit


In 1877 in Australia, H. Charlick played a correspondence game combining the Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4) with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+): see "The Evans Jerome Gambit". A similar idea has appeared in the Bishop's Opening, 1.e4 e5 2.Bc4 Bc5.

Delanoy - KameneckiCannes, France (2), 2000
1.e4 e5 2.Bc4 Bc5 3.b4

According to Bishop's Opening expert Michael Goeller,


This move is a good method of transposing to the Evans Gambit since it allows for some independent possibilities, some of which are quite favorable for White. If you like to play the Evans Gambit, this seems the most flexible way to do so..
3...Bxb4
Accepting the gambit by 3....Bxb4 challenges White to prove compensation. The resulting positions are very similar to the Evans Gambit and White probably does best to transpose to the Evans in most lines. There is one significant advantage for White, however, in offering the gambit pawn before developing the Knight to f3. In the line 4.c3 Ba5, which has proven one of the more thorny in Evans Gambit theory, White can play 5.f4!? instead of 4.Nf3 Nc6. - Goeller
4.c3

Instead, 4.f4 exf4 is the McDonnell Double Gambit, about which there is an interesting article by IM Nikolai Minev. 5.Nf3 Ne7 6.Ng5 Ng6 7.Qh5 Qf6 8.c3 h6 9.Bxf7+ Ke7 10.Bxg6 Qxg5 11.Qxg5+ hxg5 12.cxb4 d6 13.Nc3 c6 14.d4 Kf6 15.Bf5 Bxf5 16.exf5 Kxf5 17.0-0 Kg6 18.g3 fxg3 19.hxg3 d5 20.Bd2 Nd7 21.Rae1 Rh3 22.Kg2 g4 23.Ne2 Rhh8 24.Nf4+ Kh7 25.Re7 Nf6 26.Ne6 Nh5 27.Rff7 Rhe8 28.Nf4 Nxf4+ 29.gxf4 Rxe7 30.Rxe7 a5 31.a3 axb4 32.Bxb4 b5 33.Kg3 Kg6 34.Kxg4 Black resigned, was Brownson - Jerome, Iowa 1875.

Goeller gives 8...Nf6 as equal.

From here on, White consistently outplays Black in an interesting Queenless middlegame, and an instructive endgame.

14.Be3 a6 15.0-0 Kg7 16.Rac1 h6 17.Rfd1 Ne7 18.h3 c6

White has more space and better development, while Black plans his defensive formation.

19.Ne5 g5 20.f3 Ng6 21.Na4 Nxe5 22.dxe5 Rxd1+ 23.Rxd1 Nd7 24.Nb6 Nxb6 25.Bxb6

By allowing Black to double his pawns on the e-file, White has found time to put a serious cramp into his opponent's game.

25...a5 26.Rd8 a4 27.Kf2 Ra6 28.Bc5 Ra8 29.Kg3 b5

A bid for breathing space, as Black is being strangled on the Queenside.

30.Kg4 Kg6 31.Rg8+ Kf7 32.Rf8+ Kg7 33.Kh5 Bb7

Finally!

Of course, White has no interest in exchanging Rooks.

Black's next move quickens the end, but 34...Re8 would only postpone the loss, not evade it.
