Where Do Ideas Come From (Part 4)?

With thanks to our Russian correspondent Филидор1792 (Philidor 1792), another of the tales of the "large centre" marches on!



1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Nc3 Nf6 5.Bxf7+

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bd6 8.f4

The "large centre" reappears.

8...Nc6 9.e5 Re8 10.0-0 Bb4 11.d5 Bxc3 12.bxc3 Nxe5 13.fxe5 Rxe5

Black has exchanged some pieces and remains a piece ahead.

White decides to toss a pawn to delay his opponent's Queenside development, while he sets his sights on the enemy King.

14.d6 cxd6 15.Bf4 Re6 16.Bg5 Qb6+ 17.Kh1 Kg8 18.Bxf6 Rxf6 19.Rxf6 gxf6 20.Qg4+ Kf8 21.Rf1 d5

22.Qf5 Kg7 23.Qg4+ Kf7 24.Qh5+ Kg7 25.Qg4+ Kf7 26.Qh5+ Ke7 27.Qxh7+ Kd8

28.Qg8+ Kc7 29.Qxd5 Qc6 30.Qd4 b6 31.Rxf6 Qb5 32.Qd6+ Kb7 33.h4

Black has given back three pawns, and here, facing an advancing passer, he lost on time.

Where Do Ideas Come From (Part 3)?

In another Jerome Gambit game from Филидор1792 (Philidor 1792; see "Attitude" and "Where Do Ideas Come From?" Part 1 and Part 2)) we see the further exploration of the "big centre" in a rough-and-tumble game where Black defends routinely and White misses a chance to take advantage. The second player then finishes decisively. 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Nc3 Nf6 5.Bxf7+

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bd6 8.f4

The "big centre" position.

8...Nc6 9.e5 Re8

As in yesterday's game.

10.0-0 Bb4 11.d5 Bxc3 12.dxc6 Bb4 13.exf6 Qxf6

14.cxb7

Possibly underestimating the fork that he would have after the other capture, 14.cxd7, which would win a piece and give White a small edge.

The text leaves White with two pawns for his sacrificed piece, and allows him to fork Black's two Bishops; but there is a way for the defender to slip out and then counterattack.

14...Bxb7 15.Qxd7+ Re7 16.Qb5 Qb6+ 17.Qxb6 axb6 18.c3 Bc5+ 19.Kh1 Re2 White resigned

Where Do Ideas Come From (Part 2)?

Филидор1792 (see "Attitude" and "Where Do Ideas Come From?") has sent me further Jerome Gambit games and ideas.

In "Attitude" I pointed out that "Feeling confident, even when playing a bluff, is essential." 

Филидор1792 added "Of course it is important to feel confidence when bluffing, but more important is (I think you know this very well) to make others think you are bluffing, when in fact you are not."

How many times have our opponents looked at our Jerome Gambits and thought "There is nothing to this!" only to resign a dozen or two dozen moves later?

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Nc3 Nf6 5.Bxf7+

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bd6 8.f4

8...Nc6 9.e5 Re8

Differing from the previous game's 9...Bb4.

10.0-0 Bb4 11.d5 Nxe5 12.fxe5 Rxe5

Black has deftly returned a piece for two pawns, but he still has an extra one. White must continue to play with force.

13.Bf4 Re8 14.d6 cxd6 15.Nd5 Bc5+ 16.Kh1 Re6 17.Bg5 b6 18.Nxf6 gxf6 19.Rxf6+ Rxf6 20.Bxf6 Qxf6 21.Qd5+ Ke7 22.Qxa8

22...Ba6

Black is eager to show that his two Bishops and open lines are stronger than White's Rook. Unfortunately for him, the move he chooses shows just the opposite.

23.Re1+ Kf7 24.Qe8+ Kg7 25.Re7+ Kh6 26.Rf7 Qd4 27.Qf8+ Kg6 28.Qg8+ Kh6 29.Rxh7 checkmate

Sunday Tournament Update

A baker's dozen games (about 6% of the total) remain to be completed in the ChessWorld Jerome Gambit Thematic Tournament.

While AsceticKingK9 has taken first place, and a number of other finishing positions have been determined, martind1991 still can place anywhere from 8th to 15th place, depending how his games finish up.

For the time being, at least, Haroldlee123 has pulled off the two top upsets, beating players rated 411 and 329 points above him.

Where Do Ideas Come From (Part 1) ?

My Russian correspondent ("Филидор1792"  or "Philidor 1792" at http://www.bereg.ru/) who sent yesterday's Jerome Gambit game (see "Attitude") has shared some more interesting information with me, starting with the game that inspired his "big centre idea."

I think that readers will enjoy his ideas.

Attitude

When playing a gambit, especially an unsound one like the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), attitude can be very important. Feeling confident, even when playing a bluff, is essential.

In the game below, for example, sent to me from a Jerome Gambit player in Russia, White seems to have ice water in his veins...

Then You Win

Here is the latest Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) from Bill Wall, who comments modestly

I played a tough one here.  It was a 10-minute game for each side and he messed up in the end in time pressure.  He let me in the game after 38...c6 and I think he panicked on the 40th move with Nxf6 instead of Ndb6.   Up until then, I think he was winning

With all do respect to Mohandas Gandhi, who, as far as I know, never played the Jerome Gambit, the following game reminds me of something he spoke about: First they ignore... Then they laugh... Then they fight... Then you win ...

Easy As Pi

An understanding of how to play Bishops-of-opposite-colors endgames can help a player win or save many half-points. Although the basics can be simple to understand (i.e. establishing a blockade with the King and Bishop on squares of the same color as the Bishop; then safely using tempos to "pass"), carrying out the proper maneuvers can be tricky (see "A Not-so-Simple 'Simple Endgame'" and "A Not-so-Simple 'Simple Endgame' Addendum" for a recent example on this blog) especially at blitz speed, with players short of time.

This position is from IWantYourQueen  - Steftcho, blitz, FICS, 2011. Although White is a pawn ahead, Black has firmly blockaded the passer, and a draw should be routine.

White decides to give it one more try.  

65.Kf4 Kh5 66.Ke3 Kg6 67.Kd4 Kh5 68.Kc5 Kg6 69.Kd6 Kh5 70.Ke7 Kg6 71.Kf8

White's King has scrambled around to a position in front of his pawns, while Black's King patiently shuffled back and forth.

Now it is Black's Bishop to join the dance, with 71...Bg4 (or 71...Bh3) 72...Bf5, 73...Bg4, etc. and White can make no progress.

71...Kh7

Inexplicably allowing the blockade to be lifted.

72.Kf7

Of course.

72...Bg6+

Black gives up his pawn, as allowing White's g-pawn to advance (i.e. 72...Bg4 73.g6+) was suicidal.

73.Kxe6 Bf5+

Black could have tried the swindling 73...Bf7+, but if his opponent played 74.Kd6 (taking the Bishop would lead to stalemate) there would be a position with similar chances as in the game.

The text is a serious miscalculation, however, as White can take the Bishop on f5.

74.Kf7

Instead, the game would be over after 74.Kxf5 Kg8 75.g6 Kf8 76.g7+ Kf7 77.e6+ Kg8 78.e7 Kf7 79.g8Q+ Kxg8 80.e8Q+ Kh7 81.Qg6 checkmate 

Although things look dire for Black, I think that the unfortunate placement of White's Bishop, and the proper placement of Black's King, still allow a draw.

74...Bg6+ 75.Ke7 Be4 76.e6 Kg6

If Black's King had gone to g8, instead, could White have won? I do not think so. By committing to blockade the g-pawn, Black lets the e-pawn advance.

77.Kf8 Bd5 78.e7 Bc6 79.e8Q+ Bxe8 80.Kxe8

White's King now just needs to shoulder Black's King out from in front of his pawn and then it, too, can advance.

80...Kf5 81.Ke7 Kg6 82.Ke6 Kh7 83.Kf7

Too funny.

White has bypassed all of the Bishops-of-opposite-colors drawing snares, only to fall into stalemate.

Hats off to Black, for holding on to the last hope.

Just Plain Annoying

The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can be just plain annoying. Black has his mind on playing an interesting line that he has prepared, and then, suddenly, What is this?? Who wants to bother with this?

Yet, the nagging question also arises in the second player's mind: Who wants to lose to this junk? (Okay, so what do I do now?)

I think that helps explain the sudden end of the following game. It is as if Black, rated about 250 points above his opponent, realizes that he missed a move to finish off White, and decided: Phooey! I didn't really want to play this game, anyhow...

MyGameUMove - cqs

4...Kxf7 5.0-0 Nf6 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 Nc6

Black has a comfortable, better, winning position. Of course.

9.Qc4+ d5 10.exd5 Qxd5 11.Qe2 Re8 12.Be3 Kg8

More material, better development, safe King... yadda, yadda, yadda...

13.Nc3 Qe5 14.Rae1 Qd6 15.Nb5 Qd8 16.Rd1 Qe7 17.Rde1 a6 18.Qc4+ Qf7

Oh, rats! If I had played 18...Be6, it would be "Game over!"

Of course, it should have been "Game over!" after move 4, anyhow.

Why am I wasting my time on this game??

19.Qxf7+ Black forfeited by disconnection

(This might have puzzled White, who could see that after 19...Kxf7 20.Nxc7 Be6 21.Nxa8 Rxa8 he would have a Rook and two pawns against Black's two Knights, at best only a theoretical edge, if any.)

Silicon Jurassic Park

Reader quickturtle must have been browsing back posts on this blog recently (something that I highly recommend, by the way: there are almost 1,300 of them; you can use the "search this blog" Google gadget if you are looking for something special) as he posted a comment to "A Jerome Gambit 'Challenger' ", my tale of a Jerome Gambit-tinged battle against the venerable Chess Challenger 7 chess computer.

Because his comment hints at future adventures, I reprint it here:

Rick, this was a wonderful game and analysis. I still have to give the CC7 a lot of credit considering it's age and the limited amount of info those old machines had. I still have a Fidelity Designer 2100 and a Novag Super Expert and now I'm going to pull them out of the closet and give the Jerome a shot with them :)



Good luck against those silicon dinosaurs, quickturtle.

Be careful, too: remember those "Jurassic Park" movies!

How Long?

I think I have shared before that one chessfriend of mine said he enjoys playing chess at a local bar and he has found that the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is a perfect opening to play there, as, win or lose, the game is usually over quickly...

The other day I was wondering about the other end of the time spectrum: how long can a Jerome Gambit game last, especially a blitz game? I consulted The Database, and found some interesting answers.

MAILMANUK - Buckeyeski, blitz, FICS, 2002

After149 moves, this game was drawn by the "50 move rule" (although it could have been drawn, for the same reason, over 35 moves earlier)



HIARCS 11.1 UCI - Rybka 2.3.1 32-bit, 2008

Here, the two silicon monsters battled for 147 moves. 





DOCTOERDETROIT - jpiza, blitz, FICS, 2009

Here, consistent with our topic, on move 145, Black lost on time.
