Jerome Gambit: Theory and Practice (Part 2)

Another game from Vlastimil Fejfar. His opponent fearlessly offers a piece (matching the one Vlasta offered in the opening) for active counter-play, but the followup is marred by some inaccuracies, and once again the Jerome Gambit - and the gambiteer! - triumphs.  

Vlastous 2344 - Iva 1816, 2016

1 e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+
Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.Nc3 

Varying from the previous game of Vlasta's that we took a look at, which saw 10.0-0 instead.

11.d4 Ng4 12.Qg3 Qf6 

Black builds his pressure on f2. Perhaps he avoided the reasonable 12...Nxf2 because of 13.O-O!? 

13.f3 h5 

Bold! Daring White to open up his King by taking the piece. (The "objective" Stockfish 7 prefers the Knight retreat 13...Nh6.)

After White chases the enemy Queen away from her attack on the pawn at d4, he accepts the piece. 

14.Nd5 Qf7 15.fxg4 Bxg4 16.Be3 Rc8 

Both Kings will remain in the center, but White's will be safer, and the first player has an extra pawn.

17.Kd2 Qd7 

This is a tactical oversight, as it un-protects his Knight, making his Bishop loathe to move.

Vlasta is quick to respond.  

18.h3 h4 19.Qxg4 Qxg4 20.hxg4 c6 21.Nc3 b6

White is clearly better.

22.Raf1 Rc7 23.Rf5 Rh8 24.Rg5 Nf8 25.d5 c5 26.Nb5 Rd7 27.Bf4 Rh6 28.Rf5 Rf6 29.g5 Rxf5 30.exf5 


Allowing checkmate, but Black's position was untenable. White's material advantage is too great; Black's King is too vulnerable.

31.Nxd6+ Kd8 32.Rxh4 gxf5 33.Rh8 Ke7 34.Be5 Ng6 35.Re8 checkmate

Jerome Gambit: Theory and Practice (Part 1)

I recently received a couple more games from Vlastimil Fejfar (see "Correspondence Play" Parts 1, 2, 3 for an introduction) - both quite complicated.

The following game makes its way through early Jerome Gambit theory and practice, as indicated by the links to games in the notes. There is a lot to understand from the first 12 moves - and that isn't even half of the game!

The game gets more and more complicated, but Vlasta crashes through for the win. 

Vlastous 2131 - AmetovB 2074, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.O-O Rf8 

10...Kf7 was seen in perrypawnpusher - whitepandora, blitz, FICS, 2011 (1-0, 64). 

Also: 10...Ng4 11.Qc3 N6e5 12.d4 Nxh2 13.Kxh2 Qh4+ 14.Kg1 Ng4 15.Bf4 Rf8 16.Bg3 Qh5 17.f3 Nf6 18.Qxc7 Bd7 19.Bxd6 Rc8 20.Qxb7 Rf7 21.Nc3 Qg5 22.Rae1 Ng4 23.Qd5 Qxd5 24.Nxd5 Nf6 25.Ne3 Rc6 26.e5 Nh5 27.d5 Ra6 28.e6 Bxe6 29.Nc4 Rxd6 30.Nxd6+ Kd7 31.dxe6+ Kxd6 32.exf7 Black resigned, Wall,B - Guest1660564,, 2013. 


A couple of other pawn ideas:

11.f3 as in mrjoker - PhlebasP, Internet Chess Club, 2009 (1-0, 35); and 11.d4 as in De Bouver,G - Verstappen, Mechelen, 2015 (1/2-1/2, 19) 


Or 11...Qe7 as in perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 20), perrypawnpusher - obturator, blitz, FICS, 2012 (1-0, 31), and perrypawnpusher - fogab, blitz, FICS, 2014(1-0, 27); or 

11...Ng4 as in perrypawnpusher - jgknight, blitz, FICS, 2010 (1/2-1/2, 58),  perrypawnpusher - lorecai, blitz, FICS, 2010 (1-0, 47) and perrypawnpusher - dkahnd, blitz, FICS, 2011 (1-0, 24); or

11...Rf7 as in mrjoker - Mandragora, Internet Chess Club, 2008 (1-0, 49) and perrypawnpusher - dkahnd, blitz, FICS, 2010 (1-0, 30). 

12.f5 Ne7 

More frequently see is 12...Ne5 as in 13.d4 Neg4 14.Qd3 (or 14.Qf4 in perrypawnpusher - Jore, blitz, FICS, 2010 [1-0, 32] ; or 14.Qb3+ in perrypawnpusher - avgur, blitz, FICS, 2013 [0-1, 27]) 14...Kg8 15.h3 Bxf5 (or 15...Nh6 in perrypawnpusher - kenkenaditya, blitz, FICS, 2014 [1-0, 33]) 16.Rxf5 d5 17.hxg4 dxe4 18.Qxe4 Nxe4 White resigned,  perrypawnpusher - scarsetto, blitz, FICS, 2014.

Vlasta is on his own now. The first thing he does is provoke Black, allowing his own "Jerome pawns" to advance. An interesting skirmish against the Black Knights follows.

13.Qb3+ d5 14.e5 Ng4 15.Qg3 Nh6 16.f6 Ng6 17.d4 Nf5 18.Qd3

18...gxf6 19.g4 Rg8 20.Kh1 Nfh4 

The position grows more complex. Black should have kept a balanced position with 20...Nfe7 21.Rxf6+ Ke8.

21.Bg5 Bf5 

This can't be right; but look at the position.

22.gxf5 Nxe5 23.dxe5 Rxg5 24.e6+ Ke7 

Black has returned the gambit piece, and employs his King to blockade the enemy passed pawn.

Look closely, however, as his game quickly falls apart.  

25.Nc3 d4 26.Qe4 Qd6 27.Nd5+ Ke8 28.Nxf6+ Ke7 29.Qxh4 Qc6+ 30.Ne4 h6 31.Rae1 Rh8 32.Rf3 Black resigned

Complicated to the end. Look at the pins!
