Tournament Update: Ahead of the Scrum

Image result for free clip art top of the pile

As J.M. Barrie wrote in Peter Pan
All of this has happened before, and it will all happen again.
And, so it is that, once again, somehow - thank you, Jerome Gambit - I find myself at the top of the heap in my section in the second round of the "Italian Battleground" tournament at Chess.com.

With one game not yet completed, it looks like I will be followed in the standings by four players who will each have the same score. It will be up to the tie breaks to decide which two, among warwar, docfb, manospawn, and vasbur, will join me in advancing to the third round. (I won a Jerome Gambit against warwar, the only player in this group to allow the opening. If he is interested in a return match, I supect he is happy to have the edge in the tie breaks at this point.)

In the other section, two games remain to finish, but XristosGikas and 275Jukka have secured their advance, while Abhishek29 and Alfonso10 are likely to be the ones relying on tie breaks to secure an advance for one of them.

If my predictions hold, I am likely to be the 4th highest rated amongst the final 6 - but, then again, I will have my secret weapon.

No Way A GM Plays the Jerome Gambit (Part 3)

[continued from previous post]

Here is another recent game between two 2700+ rated Grandmasters, contesting an opening that had its heyday more than 150 years ago - an opening which may have inspired Alonzo Wheeler Jerome to create the Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.

Yes, even lacking the element of surprise, Grischuk played the Sarratt Attack, again. Even in blitz, that's saying something.

Grischuk, A. - Dominguez Perez, L.
St. Louis Blitz, St. Louis, 2018

1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 

Scotch Gambit.

4...Bc5 5.Ng5 

The Sarratt Attack. As long ago as 1860, in Morphy's Games of Chess, Johann Lowenthal noted
This mode of proceeding with the attack is comparatively obsolete, as, with correct play, the defence to it is perfectly satisfactory.
All is new that has been forgotten.

Perhaps both players recall Lajos Portisch's wisdom, that the goal of the opening is to reach a playable middlegame.

5...Nh6 6.Nxf7 Nxf7 7.Bxf7+ Kxf7 8.Qh5+ g6 9.Qxc5 d5



10.O-O dxe4 11.c3 Qd6 

Varying from 11...Be6, played by Karjakin.

12.cxd4 Nxd4 13.Qxd6 cxd6 



Grischuk is comfortable with exchanging Queens, as he no doubt is sure to recover a pawn, leaving his opponent with an isolated pawn - and an unsafe King. In fact, he now offers the exchange, expecting proper compensation.

14.Nc3 Bg4 15.Nxe4 Nc2 16.f3 Nxa1 17.fxg4+ Ke6 18.Ng5+ Kd7



19.Rf7+

The computer has a minor grumble with this move, preferring 19.Ne4 Nc2 20.Rd1 Kc7 21.Nxd6. This would remove the central passer, while Grischuk would prefer to improve his Kingside pawn majority.

19... Kc6 20.Nxh7 Rae8 21.Bd2 



Again, Stockfish 9 grumbles, preferring 21.Bg5, but I am not comfortable criticizing super-Grandmasters playing blitz. It comes down to what is adequate compensation for the exchange. White's Knight does seem to wander around a bit.

21...Re2 22.Bc3 Rhe8 23.Nf8 g5 24.Nh7 Nc2 25.Rf2 d5 26.Nxg5 



Mission accomplished: White has a 3 vs 0 pawn advantage on the Kingside. On the other hand, Black's overlooked passer quickly becomes a menace.

26...d4 27.Bd2 d3 28.Nf3 Rxf2 29.Kxf2 Re2+ 30.Kg3 Kd5 



White has 2 pawns for the exchange, but Black's isolani has become a troublesome passer, and his "unprotected" King is rushing into the action. Black certainly looks better - but things continue to be complicated, as the clock ticks. (For example, 30...Ne3!?, forcing 31.Bxe3 Rxe3 32.Kf4 Re2 33.h4 Ke6!? led to crazy play, with Black for choice.)

31.g5 Ke6 32.h4 Kf5 33.h5 Re4 



Black drafts the Rook to help defend against the advancing pawns, but it proves overmatched. Possibly better was returning the exchange with 33...Rxd2 34.Nxd2 Kxg5.

In the meantime, White has some interesting ideas.

34.g6 Nd4 35.Nxd4+ Rxd4 36.Kf3 Rg4 37.g3 b5 38.Bf4 



The Rook is locked up by the Bishop and pawns. White's King is free to munch on Black's pawns. Amazing.

38...a5 39.Ke3 b4 40.Kxd3 a4 41.Kc4 a3 42.bxa3 bxa3 43.Kb3 Black resigns

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??
