Further Exploration of An Odd Line

The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) has any number of unusual positions arising from White's attack and Black's defense/counterattack. The following game continues exploration of an odd one in particular, along with some very instructive tactical play. 

Wall, Bill - Guest3742987 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+ 7.c3 

This is an interesting position. Check out "LPDO Revisited", "Gloom and Doom", "Here... No, there... No, Here... No, There..." and "Never Send A Pawn To Do A Job..." for some of the earlier looks at it.

Black's response with his Queen in this game is relatively rare. (Wildest is 7...Qh4!?)

7...Qe7 8.dxe5

Some other ideas:

8.Qh5+ g6 9.Qxe5 Qxe5 10.dxe5 Bc5 11.O-O d6 12.exd6 Bxd6 13.Be3 Nf6 14.f3 Re8 15.Nd2 Be6 16.a3 Nh5 17.Rad1 Nf4 18.g3 Nd3 19.Rb1 Bc5 20.Bxc5 Nxc5 21.Rfd1 Rad8 22.Kf2 Rd7 23.Ke2 Red8 24.f4 Bg4+ 25.Ke1 Bxd1 26.Rxd1 Nb3 27.Nxb3 Rxd1+ 28.Ke2 Rh1 29.Kf3 Rxh2 30.Nd4 c5 31.Nb5 a6 32.Nc7

8.O-O Bxc3 9.bxc3 Nc6 10.Qb3+ Ke8 11.Bd2 d6 12.Na3 a6 13.e5 Qf7 14.c4 Nxd4 15.Qd3 Nc6 16.exd6 Bf5 17.Rfe1+ Kd7 18.dxc7+ Kxc7 19.Bf4+ Kc8 20.Qb3 Na5 21.Qb6 Nf6 22.Qxa5 Nh5 23.Bd6Black forfeited on time, stretto - Conga, FICS, 2007.

8... Bc5 

8...Qxe5 9.Qf3+ Nf6 10.Nd2 d5 11.cxb4 dxe4 12.Nxe4
Qxe4+ 13.Qxe4 Nxe4 14.O-O Re8 15.Be3 Kg8 16.Rac1 c6 17.Rc4 b5 Black resigned, EvanJunior - seanwickham, FICS, 2008.

9. Qd5+ 

Alternately 9.Qf3+ Ke8 10.O-O Qxe5 11.Bf4 Qf6 12.e5 Qf5 13.Nd2 d6 14.exd6 Bxd6 15.Rfe1+ Kd7 16.Nc4 Qxf4 17.Qh3+ Kd8 18.g3 Qxc4 19.Qh5 Nf6 20.Qg5 Qf7 21.Rad1 h6 22.Qe3 Re8 23.Qd2 Rxe1+ 24.Rxe1 Bf5 25.b4 Kd7 26.c4 Qxc4 27.a3 Re8 28.Rc1 Qd5 29.Qc3 Bh3 30.f3 Re2 31.a4 Rg2+ 32.Kh1 Rf2 33.Qe3 Qxf3+ 34.Qxf3 Rxf3 White resigned, jfhumphrey - kenzie, FICS 2010. 

9...Ke8 10.O-O c6 11.Qd1 d6 

There was nothing wrong with 11...Qxe5

12.b4 Bb6 13.exd6 Qe5 14.Bb2 Nf6 15.Nd2 Be6 
16.Nf3 Qf4 

If 16...Qxe4 then 17.Re1, as Bill points out; yet the central "Jerome pawns" are beginning to look like trouble. The game is about equal. 

17.Bc1 Qg4 18.Re1 Nxe4 19.Be3 Rf8 

Black probably should have gone in for the complications after 19...Nxc3 20.Qc2 Nd5 21.h3 Qf5 22.Qxf5 Bxf5 23.Bxb6+

20.Bxb6 axb6 

Now the tactics build around the Knight at e4.

21.Qd4 Rf4 22.h3 Qg6 23.Ne5 Qf5 24.Nd3 Rh4 25.Qxg7 

White grabs a pawn before returing to the pressure on e4.

25...Qf7 26. Qd4 Rd8 27. Rxe4 Rxe4 28.Qxe4 Rxd6

White is up a couple of pawns, but the tactical thrust-and-parry continues.

29.Re1 Kf8 30.Ne5 Qf5 31.Qe3 Bxa2 32.Qxb6 Rd2 33.Qe3 Rd6 34.Qc5 Qe6 35.Re3 Qh6 

36.Nd7+ Kg8 37.Qe5 Rd1+ 38.Kh2 Rxd7 39.Qe8+ Qf8 40.Qxd7 

The advantage has grown to the exchange and some pawns, and Bill is willing to simplify into a stone cold won pawn ending.

40...Bf7 41.Qxb7 Qd6+ 42.g3 Kf8 43.Rf3 Qe6 44.Qxf7+ Qxf7 45.Rxf7+ Kxf7 46.c4 Ke6 47.b5 Kd7 48.f4 Kd6 49.b6 c5 50.f5
Black resigned
