Jerome Gambit: Past is Prologue

Here is a game from the first round of the Jerome Gambit tournament at RedHotPawn.com. Both White and Black clearly have a grasp of the opening, and the battle is an entertaining one. The outcome is an indication of how the second round - and the tournament - will turn out.

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



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 



7.O-O Ng4 8.h3 Bd6 9.e5 Be7 



Recommended,but there are no other examples in The Database.

Alternatively:

9...Nxe5 Giving the piece back is "scientific" but leads to an equal game according to Stockfish 7. 10.dxe5 Bxe5 11.Qd5+ (11.f4 Bd6 12.Qd5+ Kf8 13.Nd2 Nf6 14.Qd3 b6 15.Ne4 Bb7 16.Nxd6 cxd6 17.Qxd6+ Kf7 18.Qd3 Rhe8 19.Bd2 Kg8 20.f5 Nh5 21.Bc3 Nf4 22.Qc4+ Kh8 23.Rxf4 Qh6 24.Rg4 Rg8 25.f6 g6 26.f7+ Rg7 27.Qb4 d5 28.f8=Q+ Rxf8 29.Qxf8 checkmate, Darthnik - aufdermaur, FICS, 2011) 11...Kf6 (11...Kf8 12.Qxe5 d6 13.Bg5 Qxf2+ 14.Rxf2+ Black resigned, ndrwgn - balahap, FICS, 2013) 12.Re1 d6 13.Rxe5 dxe5 14.Qd8+ Ne7 15.Qxh8 Qe4 16.Qf8+ Ke6 17.Bg5 Qb4 18.Qxg7 Bd7 19.Qf6+ Kd5 20.Nc3+ Kc4 21.b3+ Kxc3 22.Qxe5+ Qd4 23.Bd2+ Kxd2 24.Qxd4+ Kxc2 25.Rd1 Black resigned, Wall,B - Anonymous, lichess.org, 2016; or

10.hxg4 Nh6

Reasonable and straight-forward, especially since White's response "forces" Black to make a move he wants to make, anyhow; but 10...d6 was deeper and better. 

11.g5 Ng4  

Of course. Still, taking the g-pawn was better, as now the game has equalized - although that may not be apparent at first glance. 

12.Qf3+ Ke8 13.Qh3 Bxg5 14.Bxg5 Qxg5 15.Nc3 d5



15...h5!? was a thematic alternative. 

16.f4 Qg6

Thinking "attack" when "defense" was better attended to by 16...Qd8. 

17.Nxd5 Kd7 18.f5 Qg5 19.e6+ Kc6 



The alternative 19...Ke8 20.Rae1 is pretty bad for Black, but everything else leads to mate. 

20.Qc3+ Kxd5 21.Qc5+ Ke4 22.Rae1+ Ne3 23.Qe5 checkmate

"Reality" vs "the Book"


Working on the previous blog post, I noticed that the defender (counter-attacker) had played that variation a few years earlier. The game was interesting enough to share, especially since the defender seemed conversant in Jerome Gambit strategies.. Again, however, "reality" outplayed "the book".

iconsisonline - atizzle
blitz, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 



7.O-O

This is stronger than 7.dxc5 of Sutarsa - atizzle, blitz, FICS, 2014 (1-0, 19).

7...Ng4 8.h3 Bd6 9.e5 Bxe5


Following Sorensen - NN, Denmark, 1888, pragmatically returning the extra piece for a pawn (or two). Alternatives:

9...Nxf2 10.Rxf2+ Nf6 11.Rf4 Qg3 12.Rf3 Qg6 13.exd6 cxd6 14.c3 b6 15.Qb3+ Ke7 16.Re3+ Kd8 17.Na3 Bb7 18.Re2 Nh5 19.Nb5 Ng3 20.Rf2 Ne4 21.Re2 Rf8 22.Be3 Ng3 23.Rd2 Qe4 24.Re1 Rf3 25.Bg5+ Black resigned, Darthballz - Leftang, blitz, FICS, 2011; and

9...Nxe5 10.dxe5 Bxe5 11.f4 (11.Qd5+ Kf8 12.Qxe5 d6 13.Bg5 Qxf2+ 14.Rxf2+ Black resigned, ndrwgn - balahap, standard, FICS, 2013) Bd6 12.Qd5+ Kf8 13.Nd2 Nf6 14.Qd3 b6 15.Ne4 Bb7 16.Nxd6 cxd6 17.Qxd6+ Kf7 18.Qd3 Rhe8 19.Bd2 Kg8 20.f5 Nh5 21.Bc3 Nf4 22.Qc4+ Kh8 23.Rxf4 Qh6 24.Rg4 Rg8 25.f6 g6 26.f7+ Rg7 27.Qb4 d5 28.f8Q+ Rxf8 29.Qxf8 checkmate, Darthnik - aufdermaur, blitz, FICS, 2011

Black's best defense seems to be 9... Be7 10.hxg4 d6

10.dxe5 N4h6

Sorensen's opponent tried 10...Nxe5, which is playable, if risky, after 11.Qd5+ Kf6. 

11.Nc3 Ne7 12.Re1 Rf8 



Again, Black shows his understanding of the "big issues" in the defense, as he prepares to castle-by-hand.

Unfortunately, the move allows his Queen to be trapped.

White follows up quickly.

13.Re4 Qxe4 14.Nxe4 Kg8 15.Bxh6 gxh6 16.Nf6+ Kh8 17.Qd3 Ng6 18.Qc3 c6 19.Nh5 Rf5 20.e6+ Ne5 21.e7 Black resigned

Pie-in-the-Face Examples



Sometimes the best way to get the sense of an opening variation is to choose a player, and play through a series of games that he has played with it. Below, we look at several games played by ndrwgn in 2013 against a selection of opponents.

ndrwgn -  balahap
standard, FICS, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 



This is Black's strongest response to 6.d4, yet it is not well known. Of 1,0331 relevant games in The Database, only 214 (16%) show 6...Qh4

As a personal example, Bill Wall has played 6.d4 16 times, and faced 6...Qh4 on only 4 occasions. To be fair he was "only" 3-1 against the "best" move, while he was 12 - 0 against alternatives.

See the early "A Pie-in-the-Face Variation" and the recent "Going All Henry Joseph Blackburne" for additional information.

7.O-O 

The best move in a tricky position. ndrwgn had trouble with 7.dxc5 on several occasions: 7...Qxe4+ 8.Be3 Qxg2 (8... Nf6 9.O-O Rf8 10.Nc3 Qg4 11.Nd5 Qxd1 12.Raxd1 Nxd5 13.Rxd5 Nc4 14.Bd4 c6 15.Rg5 g6 16.f4 d5 17.cxd6 Nxd6 18.Bc5 Nf5 19.Bxf8 Kxf8 20.g4 Ne3 21.Re1 Nxg4 22.Rd1 Bf5 23.c3 Re8 24. h3 Ne3 25.Re1 Bxh3 26.Re5 Rxe5 27.fxe5 Nf5 28.Kh2 Bg4 29.Rf1 Ke7 30.Rf4 h5 31.Kg1 Ke6 32.Re4 Bf3 33.Re3 Nxe3 White resigned, ndrwgn - chesslayman, FICS, 2013) 9.Qh5+ Ng6 10.Rf1 Nf6 11.Qf5 d5 (11...d6 12.Qd3 dxc5 13.Nc3 Qf3 14.Bxc5 Re8+ 15.Kd2 Bg4 16.Rae1 Red8 17.Bd4 Qf4+ 18.Re3 Rxd4 White resigned, ndrwgn - balahap, FICS, 2013) 12. Nc3 Bxf5 White resigned, ndrwgn - balahap, FICS, 2013.

ndrwgn was able to outplay his opponent in a 7.Be3  game: 7...Bb4+ 8.c3 Qxe4 9.Qb3+ Kg6 10.Nd2 Qxg2? (10...Nd3+!) 11.O-O-O Nd3+ 12.Kb1 Bxc3 13.bxc3 d5 14.Rhg1 Qg4 15.Rxg4+ Bxg4 16.Rg1 h5 17.Qxd5 Re8 18.h3 Nf6 19.Qg5+ Kf7 20.hxg4 Re6 21.Nc4 hxg4 22.Ne5+ Nxe5 23.dxe5 Rh5 24.Qf4 Rhxe5 25.Rxg4 a5 26.Bd4 Re1+ 27.Kc2 R6e2+ 28.Kd3 Re4 29.Qxe4 Nxe4 30.Rxe4 Rd1+ 31.Ke2 Ra1 32.Rf4+ Ke6 33.Re4+ Kf7 34.Rf4+ Ke6 35.Bxg7 Rxa2+ 36.Kd3 a4 37.Rf6+ Ke7 38.Rf4 a3 39.Ra4 b5 40.Ra7 Rxf2 41.Rxc7+ Kd6 42.Ra7 a2 43.Bd4 Rh2 44.c4 Rh3+ 45.Kc2 Rh2+ 46.Kb3 Rh3+ 47.Kb4 bxc4 48.Rxa2 Kd5 49.Bc3 Rd3 50.Ra5+ Ke4 51.Kxc4 Black resigned,  ndrwgn - lattakiaaa, FICS, 2013

7... Ng4 

Again, this move is best - keep the attack going. Black had less success after 7...Bd6 8.dxe5 Bxe5 9.f4 (9.Qd5+!) 9...Bd4+ 10.Qxd4 Nf6 11.e5 Ng4 12.h3 Re8 13.hxg4 Qxg4 14.Qd5+ Qe6 15.Qe4 d5 16.Qxh7 Qb6+ 17.Rf2 Be6 18.Nc3 Rh8 19.Qd3 c6 20.f5 Rh5 21.fxe6+ Kxe6 22.Qg6+ Kxe5 23.Qxh5+ Kd4 24.Qg4+ Ke5 25.Bf4+ Kf6 26.Be3+ Black resigned, ndrwgn - vepara, FICS, 2013. 

8. h3 Bd6

Not quite as good as 8...Bb6, although then Black still has to be careful: 9.hxg4 Nh6  10.Qf3+ Kg8 11.Bxh6 Qxh6 12.Qb3+ Kf8 13.c3 d6 14.Nd2 Bxg4 15.Rae1 Be6 16.d5 Bg4 17.Nc4 Qg6 18.Ne3 h5 19.f3 Bh3 20.Qc2 Qg5 21.Kh2 Bxe3 22.gxh3 Bf4+ 23.Kh1 Qg3 24.Qg2 Qxg2+ 25.Kxg2 h4 26.Rg1 g5 27.c4 Ke7 28.b4 a5 29.b5 Kf6 30.a4 Ke5 31.Re2 Kd4 32.Rd1+ Kxc4 33.Rc2+ Kb3 34.Rxc7 Rhc8 35.Rxb7 Rc2+ 36.Kf1 Rh2 37.Rb1+ Kxa4 38.Kg1 Rc2 39.b6 Rac8 40.Kf1 Rc1+ 41.Rxc1 Rxc1+ 42.Ke2 Rb1 43.Kd3 Rb3+ 44.Kc2 Rxf3 45.Rc7 Rxh3 46.b7 Rb3 47.Rc4+ Ka3 48.Rc3 Rxc3+ 49.Kxc3 h3 50.b8=Q h2 51.Qb3 checkmate, ndrwgn - balahap, FICS, 2013

9.e5 

Probably best is 9.Qxg4, which still leaves Black better. Instead,  9.Qf3+ N4f6 10.e5 Be7 11.exf6 Nxf6 12.Nc3 Rf8 13.Nd5 Bd6 14.Re1 Kg8 15.Nxf6+ Qxf6 16.Qd5+ Kh8 17.Bg5 Qxf2+ 18.Kh1 Qg3 did not work, in ndrwgn - MRKumar, standard, FICS, 2013

Nonetheless, Black's plan in the current game - return a piece for two pawns - accidentally becomes over-generous, and the game shifts in White's favor.

9...Nxe5 10.dxe5 Bxe5 11.Qd5+ Kf8 12.Qxe5 d6


13.Bg5 

A trap that Black falls into by grabbing the wrong pawn.

White should have simply retreated his Queen with 13.Qc3 and a small edge.

Black should now grab the h-pawn for a slight edge.

13...Qxf2+ 14.Rxf2+ Black resigned


The check gives White time to save his Queen.
