Lost in the Maze; Then Just Lost


If, occasionally, both my opponent and I get lost in the maze of the Jerome Gambit, I feel reassured that it is my maze, and that I will still be able to find my way out, safely.

perrypawnpusher - tjaksi
blitz, FICS, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




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


7.Qd5+ Kf6 

Alert! Possible trouble on the d8-h4 diagonal!

8.d4 

Interestingly enough, Houdini shows about a half-pawn preference for 8.Qxc5 over the text. That is not immediately obvious, although both  MrJoker and I have generally had success with that move - perrypawnpusher - zsilber, blitz, FICS, 2010 (1-0, 9); perrypawnpusher - useche, blitz, FICS, 2010 (1-0, 22); perrypawnpusher - wbrandl, blitz, FICS, 2011 (0-1, 28); MrJoker - ipon, Internet Chess Club, 2011 (1-0, 33); and MrJoker -vicwill, Internet Chess Club, 2011 (1-0, 12).

8...h6

My opponent responds to the perceived threat. The computer prefers 8...Bb4+ 9.c3  and then 9...Ke7, allowing for the Black Knight to intervene at f6, e.g. 10.Bg5+ Nf6 when White will recover one of his two sacrificed pieces, but Black will still have the advantage.

Instead, 8...Bb4+ 9.c3 c6 was seen in perrypawnpusher - whitepandora, blitz, FICS, 2008 (1-0, 41); while 8...d6 9.Bg5 checkmate, from mrjoker - Taj, Internet Chess Club, 2009 also has to be mentioned.

9.Qxc5 N8e7 10.e5+ Kf7 11.Qc4+ Kf8 12.0-0 b6 


Black is preparing to take advantage of White's pieces on the a6-f1 diagonal. It was probably better to play the straight-forward 12...d5. 

13.f4 a5 14.f5 Ba6 

Much to my opponent's delight, I have fallen into his trap: the Black Bishop skewers my Queen. However, I've suggested in "BSJG: Don't Try To Out-Think Me", and here is another case of that. Instead, after the game Houdini recommended the related 14...Nxe5 15.dxe5 Ba6 when 16.Qe4 Bxf1 17.Kxf1 d5 18.exd6 cxd6 19.Nc3 d5 would be about equal, White having a pawn for the exchange.

While Black was planning his maneuver, I used my moves to allow a discovered check.

15.fxg6+ Ke8 16.Qf7 checkmate
