No Way A GM Plays the Jerome Gambit! (Part 2)

[continued from previous post]

It's true: Sad to say, you are not going to see a Grandmaster play the Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, in a serious, competitive game, any time soon.

However - what about a couple of 2700 players contesting a line of play that might have inspired Alonzo Wheeler Jerome to create his fantastical gambit?

It is quite reasonable to suspect that American chess players back in the mid- to late-1800s were familiar with the Sarratt Attack, if only because of the games Meek - Morphy, Alabama, 1855 (0-1, 21) and Kennicott - Morphy, New York, 1857 (0-1, 24). They also had access to Staunton's The Chess-Player's Handbook (1847) and Chess Praxis (1860), along with various chess magazines and newspaper chess columns.

But - modern Grandmasters?

Grischuk, A. - Karjakin, Sergey
St. Louis Blitz, St. Louis, 2018

1.e4 e5 2.Nf3 Nc6 3.d4 

The Scotch Opening.

3...exd4 4.Bc4 

The Scotch Gambit.

4...Bc5 5.Ng5 

The Sarratt Attack. It has received a number of posts on this blog. For coverage, check out "Capt. Evans Faces the Sarratt Attack".

Grischuk plays it against the previous challenger in the world chess championship!

5...Nh6 6.Nxf7 

Of course, 6.Bxf7+ was also possible.

6...Nxf7 7.Bxf7+ Kxf7 8.Qh5+ 



Look familiar?

8...g6 9.Qxc5 d5 

The proper, "scientific" response, going back to at least Mongredien, Augustus - Williams, Elijah, London Chess Club, 1853 (0-1, 23). The game is about even, but, surely, White has the element of surprise on his side.

10.O-O dxe4 11.c3 Be6 12.Bf4 Qd5 13.cxd4 Qxd4 14.Qc1


Grischuk does not want to exchange Queens. The difference in King safety is probably compensation enough for Karjakin's extra pawn.

14...Bc4 15.Re1 Bd3 16.Nc3 Rhe8 17.Bxc7 Rac8 18.Bg3 Kg8 



19.Qg5 Rf8 20.Rad1 Rf5 21.Qg4 Re8 22.Kh1 Re6 23.f3 Ne5


Quite a complicated position - and at blitz speed, too.

Instead of the text, the computer suggests exchanging pieces with 23...exf3 24.Qxd4 Nxd4 25.Rxd3 Rxe1+ 26.Bxe1 f2 27.Bxf2 Rxf2 28.Kg1 Rf4 and an even game.

Now, White gains a pawn - temporarily.

24.Bxe5 Rfxe5 25.Nxe4 Kg7 26.b3 Qb4 27.h3 Bxe4 28.Rxe4 Rxe4 29.fxe4 Rxe4 

The game is less than 1/2 over, move-wise, but it is effectively "over" - barring a blunder, which 2700s don't do very often, even at blitz.

30.Qg3 Qe7 31.Kh2 Kh6 32.Rd5 a6 33.Qd3 Qc7+ 34.Qg3 Qxg3+ 35.Kxg3 

35...Re2 36.Rd7 b5 37.a4 Re3+ 38.Kf4 Rxb3 39.axb5 Rb4+ 40.Kf3 axb5 41.Rb7 Rb1 42.Kf4 g5+ 43.Kg4 b4 44.Rb6+ Kg7 45.Kxg5 Rc1 46.Rb7+ Kg8 47.Rxb4 



The Rook + 2 pawns vs Rook + 1 pawn, pawns on the same side of the board, is a known draw. Twenty or so more moves, perhaps with a nod to the clock, do not change things.

47...Rc5+ 48.Kf6 Rc6+ 49.Ke5 Rc5+ 50.Kd6 Rc2 51.Rg4+ Kf7 52.Ke5 Rc5+ 53.Kd4 Ra5 54.Ke3 Ra3+ 55.Kf4 Ra5 56.Rg5 Ra3 57.Rg3 Ra5 58.Rf3 Kg6 59.Rb3 Ra4+ 60.Kf3 Rc4 61.g4 Ra4 62.Kg3 h6 63.Kh4 Ra5 64.Rb6+ Kg7 65.Rc6 Rb5 66.Rc3 Ra5 67.Kg3 h5 68.Rc7+ Kg6 69.Rc6+ Kg7 drawn



Wow. That was fun. White uncorked an ancient opening and managed to "lose" only half a point.

Now that the element of surprise has evaporated, Grischuk wouldn't play the Sarratt Attack again, would he??

Sunday Book Review: S.O.S. # 13

In my writing at Chessville (alas, the site is still without new content) I have reviewed a number of books in the Secrets of Opening Surprises series (#4, #6, #7, #8, #9, #10, #11, #12), edited by Jeroen Bosch. They are surprisingly addictive, sometimes startling, and always creative. As the series describes itself,

No time to study main lines? Shock your opponent with an SOS!... Secrets of Opening Surprises brings you a wide variety of unusual opening ideas. They may seem outrageous at first sight, but have proven to be perfectly playable.

After the introductory "S.O.S. Files", chronicling how earlier suggestions have worked out in over-the-board combat, Volume #13 contains:

- Sicilian Najdorf: the Czebe Attack (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Qe2!?) GM Arthur Kogan

- French Defence: Obtaining Two Bishops (1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.Nge2 dxe4 5.a3 Bxc3+ 6.Nxc3) GM Alexander Finkel

- Grabbing a Pawn in the Réti/Catalan (1.Nf3 d5 2.g3 c5 3.Bg2 Nc6 4.d4 e6 5.0-0 Bd7 6.c4) GM Glenn Flear

- Sicilian: Karma Chameleon (1.e4 c5 2.Ne2 d6 3.c3) GM Dimitri Reinderman

- The Centre Game in Viking Spirit (1.e4 e5 2.d4 exd4 3.Qxd4 Nc6 4.Qa4) IM Jeroen Bosch

- Slav: The Easy Way (1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nbd2) GM Efstratios Grivas

- Spanish: Kortchnoi's Idea in the Central Attack (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.d4 Nxd4) GM Adrian Mikhalchishin

- Panic in the London (1.d4 Nf6 2.Nf3 d6 3.Bf4 Nh5) GM Dimitri Reinderman

- Surprising Sacrifice in the Giuoco Piano (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+ 7.Bd2 Bxd2+ 8.Qxd2!) GM Ian Rogers

Another fine collection of off-the-beaten path openings!

Suddenly...Poof!


Let's go over that mental checklist (see yesterday's "I think I have a win, but it will take time...") for playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) again: surprse, inattention, over-confidence, shallow analysis and a well-timed unfortunate blunder...

I was doing fine until that last one.

perrypawnpusher - tschup
blitz FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 a6


Wow. Didn't Karpov play something like this in his match against Korchnoi in 1981? (Actually, he played it on move 5 in one game and move 6 in another. Oh, well.)

4.0-0 h6

Okay.

5.Nc3

From a practical point of view, White might do best to head toward a Scotch Game or Gambit with 5.d4, counting on the tempos gained by Black's Rook pawn moves.

5...Nf6

A few years ago, my patience was rewarded – with a delayed Jerome Gambit – after 5...Bc5 6.Bxf7+ Kxf7 7.Nxe5+ Nxe5 8.Qh5+ Ke6 9.Qf5+ Kd6 10.d4 Bxd4 11.Rd1 c5 12.Ne2 Kc7 13.Nxd4 d6 14.Ne6+ Bxe6 15.Qxe6 Nf6 16.Bf4 Re8 17.Qb3 Nxe4 18.Bxe5 Rxe5 19.Qf7+ Qd7 20.Qf3 Qf5 21.Qxf5 Rxf5 22.f3 Ng5 23.Re1 Kd7 24.Rad1 Re8 25.Rxe8 Kxe8 26.Rxd6 Re5 27.Kf2 Ke7 28.Rb6 Rf5 29.Rxb7+ Kf6 30.Rb6+ Kf7 31.Rxa6 Ne4+ 32.Ke3 Nd6 33.Rxd6 Ke7 34.Rd3 Rh5 35.h3 Re5+ 36.Kf2 g5 37.Re3 Rxe3 38.Kxe3 Kd6 39.Ke4 c4 40.Kd4 Black resigned, perrypawnpusher - angelosgoulianos, blitz FICS, 2007.

6.d3 Bc5

Finally! He plays it after I've already played d2-d3...

Wait a minute. If he's "wasted" two moves, can't I afford to "waste" one move myself?

Sure, why not??

7.Bxf7+


Ahhh, that feels better...

I suppose that this is a Delayed Semi-Italian Four Knights Jerome Gambit.

7...Kxf7 8.Nxe5+ Nxe5 9.d4


9...d6

Reminiscent of my game against FrankMCMLVII.

10.dxc5 Bg4

Okay, this guy is definitely playing with my head. The text move is good for Black, but the simple 10...dxc5 was even better.

11.f3 Bh5 12.g4 Nexg4


Not unexpected, but after the game Rybka preferred 12...Bg6, suggesting further 13.f4 Nexg4 14.cxd6 Qxd6 15.Qxd6 cxd6 16.h3 Nxe4 17.Nxe4 Bxe4 18.hxg4 h5 19.g5 Bxc2 with Black better by a pawn.

13.fxg4 Bg6


14.g5 hxg5 15.Bxg5


I did not see it at the time, but White is better here, especially if he can get in Qd1-d5+, something that Black prevents with his next move.

15...dxc5 16.Qf3


After the game Rybka recommended 16.e5 Qd4+ 17.Qxd4 cxd4 18.Nd5 which wins a piece for White.

16...Qd4+ 17.Kh1 Qe5


Black's centralized Queen now gives him counter-chances and equality.

18.Bxf6

Wow! Speaking of "a well-timed unfortunate blunder..."

The position would wind down after 18.Bf4 Qxe4 19.Nxe4 Bxe4 20.Qxe4 Nxe4 21.Bxc7+ Nf6
