Nudge 2.0

The other day Bill Wall told me that there were 5 Jerome Gambit games (out of over 4.8 million) in the new Big Database 2011 from ChessBase. It turns out that 2 of them were unknown to me. Here's one.

Kitzler,G - Schloeffel,C
Karl Mala Memorial FICS, 2009

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

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

7.Qxc5

Instead of this direct capture, I prefer the "nudge" 7.Qd5+ which usually pushes Black's King to the back rank, where it can interfere with the development of his King Rook. It costs me an extra tempo, but Black returns it with a later ...Kf7 or ...Ke7.

7...d6 8.Qd5+

I suppose that this move could be a "nudge 2.0" as it either moves Black's King, or the Queen's check is blocked by Black's light-squared Bishop, which in turn makes the b7 pawn available for capture.

How good is the move? Well, there are 127 games with it in The Database, and White scores only 37%. On the other hand, the move has been played by Jerome Gambit stalwarts blackburne, AAlekhine and Bill Wall, and was chosen by computers Crafty 19.19 and Yace Paderborn in their games against RevvedUp.

8...Be6 9.Qxb7

Black willingly gives up the pawn and White happily takes it. At least one of them apparently remembers what happens to one who takes the Queen's Knight pawn...

As in many Jerome Gambit positions, Black is "objectively" better, but if White can consolidate his position (he is behind in development and his King is not safe) then in casual or club games White's extra 3 pawns may be able to balance out Black's extra piece.

9...Nf4

Two other possibilities:

9...Nf6 10.d4 Re8 11.Nc3 Qc8 12.Qb5 Bd7 13.Qd3 Nxe4 14.0-0 Kg8 15.Bg5 Nxg5 16.Rae1 c6 17.Qc4+ d5 18.Qd3 Rxe1 19.Rxe1 Bf5 20.Qd2 Ne4 21.Nxe4 Bxe4 22.f3 Bf5 23.g4 Bxg4 24.fxg4 Qxg4+ 25.Kh1 Nh4 26.Qe2 Qxe2 27.Rxe2 Rf8 28.h3 Kf7 29.Re3 Re8 30.Rxe8 Kxe8 31.c3 Ke7 32.Kg1 Ke6 33.Kf2 Kf5 34.Kg3 g5 35.a4 h5 36.b3 Ke4 37.Kf2 Kd3 White resigned, blackburne - meliam, ChessWorld, 2004; and


9...Nh4 10.0-0 Qg5 11.Qxc7+ Ne7 12.g3 Nf3+ 13.Kh1 Qh6 14.h4 Bh3 15.Rd1 Qe6 16.Qa5 Bf1 17.Qh5+ Ng6 18.Qxf3+ Kg8 19.Rxf1 Qh3+ 20.Kg1 Ne5 21.Qb3+ d5 22.Qxd5+ Nf7 23.Qxa8+ Black resigned, Wall - CheckMe, Chess.com, 2010.


Players who return to this line also need be aware of the unplayed 9...Qg5!? Trust me, the Black Rook on a8 is poisoned. White has to try 10.g3. 

10.0-0

This move seems prudent, but it actually opens up Pandora's box. White had to find 10.Rg1 and hold on, as Black has both quiet and wacky responses (try 10...Bd5!?) to try to increase his advantage.

10...Bh3

Okay, take a deep breath.

Black, as is the case in many Jerome Gambit games, has missed the killing stroke 10...Qg5, as 11.g3 causes horrible weaknesses on the white squares around White's King, i.e. 11...Ne2+ and 12...Qh5.

Instead, Black has gone in for flash (taking the Bishop now leads to a quick mate), and that means White has an extra chance. He should try 11.Qb3+, hoping for something like 11...d5 12.d4 Qg5 13.Qg3 Ne2+ 14.Kh1 Nxg3+ 15.fxg3+ Qf6 16.Rxf6+ Nxf6 17.gxh3 Nxe4 when White has two pawns for the exchange and Black will have to work for a win.

After 11.Qb3+ Ke8 12.Qb5+ White should probably exchange Queens if he has the opportunity and otherwise work on his development, again hoping that his 3 extra pawns will come to his rescue.

11.e5

Opening the route to g2 for his Queen, but now his game completely collapses. It is probably time to draw the curtain on this tragedy.

11...Bxg2 12.Qb3+ Bd5 13.e6+ Kf8 14.Re1 Bxb3 15.e7+ Nxe7 16.axb3 Nf5 17.Kh1 Nh3 18.d3 Qh4 19.Rf1 Nxf2+ 20.Kg2 Re8 21.Rxf2 Qg4+ 22.Kf1 Qh3+ 23.Rg2 Qf3+ White resigned

White's undeveloped Queenside tells the tale.
