A Whole Lot of Chess in Three Minutes


The following game is a roller coaster ride of chess. Hang on, there's whole lot of chess in this 3-minute game!

Philidor 1792 - Bojokrupanj1
blitz 3 0, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7 Qf5+ Kd6 8.f4 Ng6



This line must be considered inexact, as it transposes with an extra move (f2-f4)  to the 6...Ng6 defense, as in Philidor1792 - jenskun, Russia Central Federal District vs Phil, Chess.com, 2015 (1-0, 27).

9.Qd5+ Ke7 10.Qxc5+ d6 11.Qg5+ 

Stockfish 6 likes this move better than 11.Qe3, which appeared in a lot of my games; although it prefers 11.Qa3 the most.

11...Kd7 12.Qg4+ Ke8 13.Qg3 



There is only one other game in The Database with this position, Leonas - amec_pt2005, ChessHere.com, 2009 (0-1, 30) which now continued 13...Qh4 14.Qxh4 Nxh4.

13...Nf6 14.Nc3

14.d3 was correct; now things become more difficult for White.

14...Nh5 15.Qf3 Nhxf4 16.0-0 Rf8 17.d4 Nh3+ 18.gxh3 Rxf3 19.Rxf3 Qh4



White may have lost his Queen for a Rook, but he has not lost his fighting spirit.

20.Be3 Be6 21.Raf1 c6 22.Bf2 Qh5 23.Bg3 Kd7 24.d5 cxd5 25.exd5 Bxd5 26.Rd3 Bc6 27.Rxd6+ Ke8 28.Re6+ Kd7 29.Rd6+ Kc8

Black declines allowing a draw by repetition. This gives his opponent more chances to concoct devious notions.

30.Rf7 Qxh3 

Time is growing shorter. Black grabs a pawn and eyes the White King.

31.Kf2

Both players overlooked 31.Nd5!? Bd7 32.Rxg6 hxg6 33.Rf8+ Be8 34.Rxe8+ Kd7 35.Rxa8 and White would have ample material for his Queen. 

31...Qg2+ 32.Ke3 Qg1+ 33.Ke2 Qg2+ 34.Rf2 Qh3 35.Rf7 Qg4+ 36.Ke1 Be8 

White's King has proven elusive, much to Black's dismay. Time is almost up, and White continues combining.

37.Rc7+ Kxc7 38.Rxg6+ 



Here Black's flag must have fallen, as after 38...Qxg3+ 39.Rxg3  Bg6 the position would have been about even.

Theory on Non-Theory



Even in the non-main-line lines of the non-main-line Jerome Gambit, there is theory, and practice, as Philidor1792 demonstrates in the game below.

Philidor1792 - jenskun
Russia Central Federal District vs Phil, 
Chess.com, 2015

1.e4 e5 2. Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 



5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke7 



Infrequently played, but not bad.

8. Qxc5+

The experimental 8.Qg5+ was tried in Wall,B - CKFM, FICS, 2012 (1-0, 44). 

8... d6 9. Qe3 

The Database has three games with 9.Qg5+: fehim - Schiele, FICS, 2006, (0-1, 59); stampyshortlegs - calchess10, JGTourney4, ChessWorld 2009 (1-0, 31); and Wall,B - Vassilev,R, Chess.com, 2010 (1-0, 32).

9... Be6

Instead, 9... Nf6 was seen in three MrJoker games:  MrJoker - Yuvi, ICC, 2011 (1-0, 16); MrJoker - Cleanbishop, ICC, 2012 (1-0, 46); and MrJoker - taz, ICC, 2013 (1-0, 43).

The Bishop move seems to invite f2-f4 by White, gaining a tempo.

10.O-O Nf6 11.f4 Bf7 12.f5 Ne5 13.d4 Nc6 14.e5 dxe5 15.dxe5 Nd5 16.Qg3 Kf8 

The extra tempo for White, the "Jerome pawns" and Black's uneasy King have lead to an equal game. As we have frequently seen in Jerome Gambit lore, when White has equalized, he has the advantage.

17.Bg5 Qc8 18.e6 Bh5 19.Nc3 Nxc3 20.Qxc3 Rg8 21.f6 gxf6 22.Qxf6+ Ke8 23.Rad1 Qd8 24.Rxd8+ Rxd8 25.b4 b5 26.a4 a6 27.axb5 Black resigned
