SIRMO

While preparing "Jerome Gambit for Dummies (5)" I realized that I had published only two games of the Jerome Gambit thematic tournament winner, SIRMO: plummy - SIRMO, chessworld.net, 2007 (0-1, 49) and Bullit52 - SIRMO, chessworld.net, 2007 (0-1, 12).
I think I may have unfairly shied away from his games because SIRMO prefers the "modern" Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) variations – not playing 5.Nxe5+ after 4...Kxf7 – and because a number of his wins feature a certain amount of wizardry...
Here are SIRMO's Jerome Gambit wins with white.

SIRMO - AAlekhine
thematic www.chessworld.net, 12.2007
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kf8 [Hardly the way to refute the Jerome Gambit! - Rick] 5.Bxg8 Rxg8 6.c3 Qf6 7.d3 d6 8.a4 Ke8 9.Bg5 Qg6 10.h4 h6 11.h5 Qe6 12.Bd2 Bd7 13.b4 Bxf2+ 14.Kxf2 Rf8 15.Rh3 Ke7 16.Be3 Rae8 17.b5 Na5 18.Nbd2 Kd8 19.Ke2 Kc8 20.c4 g5 21.Nh2 Qf6 22.Rf3 Qe6 23.Qf1 g4 24.Rxf8 g3 25.Rxe8+ Bxe8 26.Nhf3 Bxh5 27.Qh1 Qf7 28.Qh3+ Kb8 29.Qxg3 b6 30.Bxh6 Nb7 31.Qg7 Qxg7 32.Bxg7 Nc5 33.a5 Ne6 34.Bf6 Nf4+ 35.Kf1 Nxd3 36.axb6 cxb6 37.Be7 Kc8 38.Bxd6 Kd7 39.Nxe5+ Nxe5 40.Bxe5 Ke6 41.Bc7 Kd7 42.Rxa7 Kc8 43.Bxb6 Kb8 44.c5 Bd1 45.Nc4 Bb3 46.Nd6 Bc2 47.Rd7 1-0

Fool me once...

Here I am again, playing a 3 0 blitz quickie with Black. No way my opponent – rated higher than me – is going to play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), right? Right?? Sigh. Having forgotten the lesson of "I don't have time for this stuff..." I get to learn it all over again. Serves me right.

madmadmal - perrypawnpusher blitz 3 0, FICS, 2009 

1.e4 e5 2.Bc4 Bc5 3.Nf3 Nc6 4.d3 Nf6 5.Bxf7+ Kxf7 Transposing to a modern variation of the Jerome Gambit. I have 77 examples of this position in my database, including bushytail - perrypawnpusher, blitz FICS 2008 (1/2-1/2, 50); drewbear - perrypawnpusher, chessworld 2008 (0-1, 22); and Mika76 - perrypawnpusher, GameKnot.com 2008 (1-0, 32). 

 6.Ng5+ Ke8 7.Nc3 d6 8.Nd5 A bit unusual, but it's shown up four times before, including NMTIGER - blackburne, Chessworld 2007: 8...Nxd5 9.exd5 Ne7 10.c4 Ng6 11.Qf3 Qf6 12.Ne6 Bxe6 13.dxe6 Rf8 14.0-0 Qxf3 15.gxf3 Rxf3 16.Be3 Bxe3 17.fxe3 Rf6 18.Rxf6 gxf6 19.Rf1 Ke7 20.d4 Kxe6 21.d5+ Ke7 22.e4 Rg8 23.b4 Nf4+ 24.Kh1 Rg2 25.Rxf4 Rxa2 26.Rh4 Re2 27.Rxh7+ Kd8 28.Rf7 b6 29.Rxf6 Kc8 30.Rf8+ Kb7 31.b5 Rxe4 32.Kg2 Rxc4 33.Kg3 Rc1 34.h4 Rh1 35.Rh8 e4 36.Kg2 Rd1 37.Re8 Rxd5 38.Rxe4 Rxb5 39.Rg4 Rh5 40.Kg3 b5 41.Rg5 Rh8 42.Rxb5+ Kc6 43.Rb1 a5 44.Rc1+ Kb6 45.Rb1+ Ka6 46.Kg4 a4 47.h5 Ka5 48.Kg5 a3 49.h6 Ka4 50.Kg6 a2 51.Ra1 Ka3 52.Kg7 Rxh6 53.Kxh6 Kb2 54.Rh1 a1Q 55.Rxa1 Kxa1 56.Kg5 c5 57.Kf4 c4 58.Ke3 c3 59.Kd3 Kb2 60.Kd4 c2 61.Kd5 c1R 62.Kxd6 Rc4 63.Kd5 Kc3 64.Ke5 Rd4 65.Kf5 Kc4 66.Ke5 Kc5 67.Kf5 Kd6 White resigned 

  8...h6 9.Nf3 Kf7 10.0-0 Rf8 Black is up a piece for a pawn, and is soon to castle-by-hand. What's the problem?

Tick, tick, tick... 

11.Nh4 Kg8 12.Ng6 Rf7 13.a3

My opponent begins to feel the clock, too. 

13...Be6 14.c4 Bxd5 

Chopping wood, a good idea when a piece up but this game is going to end with either a flag or a mate, so perhaps not the best. 

15.cxd5 Ne7 16.Nh4 Qd7 17.b4 Bd4 18.Rb1 Qg4 See the above note. 

19.Qxg4 Nxg4 20.Kh1 Simply returning the Knight to f3 was best. Now Black can win the exchange with 20...Nxf2+ 21.Rxf2 ( if 21.Kg1 Nh3+ 22.Kh1 Rxf1#) 21...Rxf2 and then go for more, as in 22.g4 Rf1+ 23.Kg2 Rg1+ 24.Kh3 Be3 winning a piece. 

20...Rxf2 21.Rxf2 Nxf2+ 22.Kg1 Nxd3+ 23.Kf1 Nxc1 24.Rxc1 Rf8+ It's all clickin', but the clock's still tickin'. 

25.Ke2 g5 26.Nf3 Bb6 27.a4 a6 28.a5 Ba7 29.h4 We're pretty much just throwing moves at each other now. 

29...Bb8 30.hxg5 hxg5 31.g4 Kg7 32.Nxg5 Kg6 33.Ne6 Rh8 34.Kd3 Rh3+ 35.Kc2 Rg3 36.Kb2 Rxg4 37.Nxc7 Rxe4 38.Ne6 Rxb4+ 39.Ka3 Rb5 40.Nf8+ Kf7 41.Nh7 Rxa5+ 42.Kb3 Rxd5 43.Ng5+ Kf6 44.Ne4+ Ke6 45.Ng5+ Kf5 46.Nf3 Kf4 47.Rf1 Ke3 48.Ng5 Rb5+ 49.Kc2 d5 50.Rf3+ Kd4 51.Ne6+ Kc4 52.Rc3+ Kb4 53.Rb3+ Black forfeits on time

Oh, well.

Three cheers for madmadmal and the Jerome Gambit!!!

Trading up!

Chessfriend Martin Moller (who plays at the Internet Chess Club as "Moller" and who posts at ChessGames) is the first reader to send in a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game since requested (see "Looking for a few good Jerome Gambit games..." and "Still Looking for a few good Jerome Gambit games...").

As a result, he will receive a PGN file of the first 210 games referred to on this blog, and a PGN file of the next 250 (actually 272) as well.
Let's take a look at his contribution -- a 5 minute blitz game, against a player rated 200 points above him.

White's pawns begin to roll, and Black's pieces scramble to get out of the way. The second player has a material and development advantage -- but the clock is ticking!

12.f5 Bd7 13.Qb3+ d5 14.Nc3 c6 15.Bg5 h6


Double-edged play: it will weaken Black's Kingside, but he plans on using the "holes" as open lines for counter-attack.

Bluff? Black doesn't want to find out. You have to make split-second decisions in 5-minute games.

21...Qc7 22.e5 Rag8





23.e6+ Bxe6 24.fxe6+ Kxe6 25.Rae1+




25...Kd6
The King was "safer" at f7, but things are very difficult even then.

26.Rxf6+

Good enough, although 26.Qc5+ 13.Kd7 27.Rxe7+ was even stronger.

26...Kd7 27.g3 Black disconnected.
I don't know about at ICC, but at FICS if someone disconnected here, the game would be awarded to White.
Exciting chess!

Pitfall Numero Uno in the Jerome Gambit

It's not often you find that you have a won game – with the black pieces, at move 4.
Defending against the Jerome Gambit has its benefits, that's for sure.
The one thing you shouldn't do – besides panic, that is (see "The Horror! The Horror!!") – is dwadle ((v) : to spend time idly and unfruitfully; to spend time without haste or purpose – ninjawords).
The following game, from the recently completed ChessWorld tournament reviewed in Unorthodox Opening Newsletter #21, which I mentioned in "But is this stuff playable? (Part II)," gives an example of how Black may fall if he lets his game drift.
Nestor250168 - NMTIGER
thematic www.chessworld.net, 12.2007
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5

Up to this point we have also been following the game "Anonymous vs Anonymous" presented in L. Elliot Fletcher's delightful Gambits Accepted, A Survey of Opening Sacrifices, (1954).

Fletcher's comment about the games he collected are worth recalling

Every inventor must have considered his gambit as a winning one, so in this Part all gambits are won by White and all counter gambits by Black. One game for each of the eighty-four openings is included, being numbered according to the classification tabulated in Part I, and, as far as possible, short games have been selected from master play. This was not as easy as might be imagined, for so often an otherwise suitable tournament or match game was not won by the proper colour required for our purpose. In several cases, therefore, it has been necessary to search for games outside first-class circles, and, in the thirteen selections when this has been done, the names of the players have been suppressed and the contest given as a Club Game. It must be confessed that the collection thereby becomes rather a mixed bag, but at least it can be said that there is an example, and a winning one, for each opening...
7...d6 8.Qc3 Nf6 9.d3 Re8 10.0–0

Here it can be noted that Nestor 250168 had the Black pieces in another game in this tournament, vs AAlekhine, and was successful there as well: 10.Bg5 Re6 11.Nd2 h6 12.Bxf6 Rxf6 13.0–0 Be6 14.Nf3 Kg8 15.h4 c5 16.h5 Nf4 17.Qd2 Nxh5 18.e5 Rf5 19.exd6 Qxd6 20.Rae1 c4 21.d4 Raf8 22.Nh4 R5f6 23.Re2 Ng3 24.Rfe1 Nxe2+ 25.Qxe2 Qxd4 26.c3 Qxf2+ 27.Qxf2 Rxf2 28.Rxe6 Rxb2 29.Ng6 Rf6 30.Ne7+ Kf7 31.Re4 Re6 32.Nf5 Rxe4 33.Nd6+ Kg6 34.Nxe4 Rxa2 35.Nd6 Rc2 36.Nxc4 Rxc3 37.Nd6 a5 38.Nxb7 a4 39.Nd6 a3 40.Nb5 Rc1+ 41.Kf2 a2 42.Nd4 a1Q 43.Nb3 Qb2+ 0–1
10...b6 11.Bg5 Ne5

Too much horsing around will be his downfall.

12.f4 Neg4 13.h3 Ne3 14.Rf3 Nd1

Black must try 14...d5 and be prepared to fight furiously, when the first player can keep an even game with 15.Qb3 Nc4 16.e5 Na5 17.Qa3 Bb7 18.Nd2, or enter the Twilight Zone with 15.Rxe3!? d4 16.Qc6 dxe3 17.Qxa8 Qd4 18.Nc3 e2+ 19.Kh2 Qf2 20.Qxa7 e1Q 21.Rxe1 Qxe1 22.Qxc7+ Kg8 23.Bxf6 gxf6 24.Nd5 Qh4 25.f5 Kh8 26.Qxb6




White has six pawns for a Rook and is a) winning, b) losing, or c) keeping the game in balance.
I chose d) one of the above. (I'm not sure which.)
15.Qb3+ Be6 16.c4 Nxb2 17.Qxb2 h6 18.Bxf6
There is something to be said for 18.Bh4 instead in that it keeps the pressure on his opponent's position. As it is, things soon fall apart for the second player anyhow.
