New, Old, New, Old...



The following game has a funny mix of things that were "new" to me and things that were "old" friends. After yesterday's challenging loss, it was nice to return to winning ways.

perrypawnpusher - gmann
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.Nc3

I've always played 4.0-0 here, as in an earlier game against my opponent, perrypawnpusher - gmann, blitz, FICS, 2010 (1-0, 39), but recent posts on this blog got me thinking about trying something new. Nothing came of it this time, however.

4...Nf6 5.0-0 Bc5

The game has transposed to the not-so-new Semi-Italian Four Knights Game, something that I have played over 45 times.

6.Bxf7+


6...Kxf7 7.Nxe5+ Nxe5 8.d4 Bxd4

An interesting idea was 8...Ng6, which I saw in perrypawnpusher - richardachatz, blitz, FICS, 2010 (1-0, 20) and later in perrypawnpusher - gmann, blitz, FICS, 2010 (1-0, 21).

9.Qxd4

9...Nc6 10.Qd3

An  old decision. The computers prefer 10.Qc4+, but I have had mixed results with the move: perrypawnpusher - mjmonday, blitz, FICS, 2010 (0-1,26),  perrypawnpusher - DeDaapse, blitz, FICS, 2010 (0-1, 19), and perrypawnpusher - transilvania, blitz, FICS, 2011 (1-0, 12).

10...d6 11.f4 g6

This was new to me. It was hard to look at the pawn pair at g6 and h6 and think that at least one of them should have stayed on its original square. This is not a major error, nothing to upset the fact the Black is better; but one way that Black loses in the Jerome Gambit is by the accumulation of small disadvantages.

12.Bd2 Nb4

Ah, yes, an old friend again... I am almost over feeling guilty when my opponents play this kind of move (When in doubt, harass the Queen!).

13.Qc4+ Be6

After the game Houdini showed a preference for 13...d5 14.Qxb4 dxe4 followed by 15.Nb5 a6 16.Qc4+ Be6 17.Qxc7+ Qxc7 18.Nxc7 Rac8 19.Nxe6 Kxe6 when White was a bit better.

14.Qxb4 Rb8 15.e5 Nd5 16.Nxd5 Bxd5 17.Qd4



This centralizing move is okay, but after the game Houdini recommended the more aggressive 17.f5. Now Black should retreat his Bishop.

17...c6 18.c4 Bxc4 19.Qxc4+ d5 20.Qd3 Kg7



Reaching the sanctuary he prepared on move 11, but it is too late.

21.Bc3 Kh7 22.f5 Qg5 23.fxg6+ Qxg6 24.Qxg6+

An old habit: simplify to an ending (missing 24.Rf7+ Kg8 25.Qxg6 checkmate).

24...Kxg6 25.Rf6+ Kg7 26.Raf1


26...Rhf8 27.Rxf8 Rxf8 28.e6+ Kg8 29.e7 Re8 30.Re1 Kf7 31.Bb4 b6 32.Bd6 b5

33.Rf1+ Ke6 34.Rf8 Rxe7 35.Bxe7 Kxe7 36.Ra8 Black resigned

Struggling

I have seen games where a player gives odds of pawn, Knight, Rook or Queen and then wins brilliantly. I do not know how many games where the odds-acceptor's wins have been published. Here is one I gave "Jerome Gambit odds" and lost.


 perrypawnpusher  - pblond
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Bc5 5.Bxf7+


The Semi-Italian Jerome Gambit.

Of course, White does not have to sacrifice. He can keep a small edge with 5.c3 d6 6.d4 exd4 7.cxd4 Bb6 8.Nc3 Nf6 9.h3 0-0.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ke6


I have played this position a number of times. The deeper I get into the game, the more it feels like I am walking through a junkyard, and I keep expecting to see myself amongst the wrecks.

8.Qf5+ Kd6 9.d4 Bxd4

The capture seems best, but has not always been played:

9...Qf6 10.dxe5+ Qxe5 11.Rd1+ (11.Bf4 Black resigned, perrypawnpusher - joejox, FICS 2009) 11...Bd4 12.Qf8+ Ke6 13.Qe8+ Kf6 14.Qf8+ Ke6 15.Qe8+ Kf6 draw, perrypawnpusher - Joyus, blitz, FICS, 2007 ;

9...Ne7 10.Qxe5+ Kc6 11.Qxc5 checkmate, perrypawnpusher - GabrielH, blitz, FICS, 2010 & perrypawnpusher - StockholmMoskva, blitz, FICS, 2010.

10.Rd1 c5


A reasonable move, but not actually necessary, as my opponent showed in perrypawnpusher - richardachatz, blitz, FICS, 2010 (1/2-1/2, 71) by playing 10...Ke7. Remember, Black is two pieces up. In that game I was lucky to swindle my way to a draw.

Also good for Black is 10...Qf6 11.Rxd4+ Ke7.

11.c3 Ne7

12.Qh3

I have played this move successfully before, but I think that 12.Qh5 as in perrypawnpusher - Lakritzl, blitz, FICS, 2009 (1-0, 20) and perrypawnpusher - tuffmom, blitz, FICS, 2010 (1-0, 26) or 12.Qf4 as in perrypawnpusher - Xasquete, blitz, FICS, 2010 (1-0, 46) might be better.

In truth, all still leave White struggling for even equality.

12...Kc7

Stepping out of the pin, although also good for Black was 12...N7g6 as in perrypawnpusher - Repunante, blitz, FICS, 2010 (1-0, 17). [Hmmm... doesn't look like I've posted this game here yet - RK]

13.cxd4 cxd4

Or 13...d6 14.Qc3 Nd7 15.dxc5 Nxc5 16.Bf4 b6 17.b4 Kc6 Black resigned, perrypawnpusher - tuffmom, blitz, FICS, 2010.

14.Rxd4 d6

perrypawnpusher - Jantra, blitz, FICS, 2010 continued with 14...N7c6 (1-0, 26) Black probably should have played 14...Kb8 first.

15.Qc3+ N7c6 16.Bf4


After the game Rybka recommended 16.f4, giving Black an edge after 16...Nf7 17.Be3 g5

16...Qf6

Black's defense is now solidly in place. He is even threatening to win the exchange after 17.Bg3 Nf3+ 18.gxf3 Qxd4.

17.Bxe5 Qxe5 18.Rc4 Be6


Black is ready to finish up.

19.Qxe5 dxe5 20.Rc1 Rac8 21.b4


Hope springs eternal, but Black is even able to castle-by-hand on the Queenside. White has nothing for his sacrificed piece (the extra pawn is meaningless).

21...Kb8 22.Nd2 Nd4 23.a4 Ne2+ White resigned


Whew! This was a very good game by pblond, and it certainly shows what a struggle the Jerome Gambit can sometimes deliver – for White.

Feeling Lucky

A couple of months ago I faced a defense similar to the one played in today's game. When I annotated that older effort for this blog, I suggested an improvement for White, should anyone ever pass that way again.

The suggestion quickly proved its worth.

perrypawnpusher - gmann
blitz, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Nf6 5.Nc3 Bc5


The Semi-Italian Four Knights Game.

6.Bxf7+

The Semi-Italian Four Knights Jerome Gambit.

6...Kxf7 7.Nxe5+ Nxe5 8.d4 Ng6


This move is a bit unusual, but still keeps Black's advantage. How nice to be two pieces up!

9.dxc5 Re8 10.f4

This is a move that I suggested in my notes to perrypawnpusher - richardachatz, blitz, FICS, 2010, as an alternative to 10.Re1, to be tried if one were "feeling lucky".

10...Nxe4

All right! 

Anyone who plays the Jerome Gambit regularly is familiar with the negative "halo effect" that affects some skeptical opponents. They think: If White blunders so badly in the opening, he is going to blunder throughout the game. So any move that appears bad, must be bad.  

11.Nxe4 Rxe4 12.Qd5+ Re6 13.f5


This should leave White ahead the exchange. Black's next move, hoping to dislodge the pinning Queen, only makes matters worse.

13...c6 14.fxe6+ Kg8 15.e7+


15...cxd5 16.exd8Q+ Kh7 17.b4


Preparing to put the Bishop on b2, when the attack on g7 will become overwhelming.

17...b6 18.cxb6 Bb7 19.Qxd7 Ba6 20.Bb2 Rg8 21.Rf7 Black resigned

I don't know that I will have any future success with 10.f4, but I will play it again – when I am feeling lucky.

Walking Through A Junkyard

Giving "Jerome Gambit odds" can feel like a walk through a junkyard. You pass wreck after wreck and your only hope is that you will find something to get you out of there.

perrypawnpusher - Jantra
blitz, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6

The Semi-Italian Opening.


4.0-0 Bc5 5.Bxf7+


The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ke6


8.Qf5+

The computer-recommended follow-up is 8.Qh3+ Ke7 9.Qc3 d6 10.d4 Bxd4 11.Qxd4 Nf6 12.Nc3 although this leads to a position that is almost identical to a position from the Semi-Italian Four Knights Jerome Gambit: Black's King is on e7 instead of f7, and it is his move instead of White's.

Amusingly, at this point, until about a depth of 12 moves, Fritz8 recommends the next two moves for Black to be ...Re8 and ...Kf7, which would be identical to the Semi-Italian Four Knight's Jerome Gambit, except that the recommended move for White in the interim is Bf4, not f2-f4.

8...Kd6 9.d4

Moving the pawn directly seems better than preparing for it, as in prettyhip1 - cubs0_0, GameKnot.com, 2007: 9.Rd1 Ne7 10.Qh5 g6 11.Qh3 Bd4 12.Qa3+ Bc5 13.b4 Bd4 14.c3 Bxf2+ 15.Kxf2 Rf8+ 16.Ke3 White resigned.

9...Bxd4


The right idea. Problems came with

9...Qf6 10.dxe5+ Qxe5 11.Rd1+ (11.Bf4 Black resigned, perrypawnpusher - joejox, blitz, FICS, 2009) 11...Bd4 12.Qf8+ Ke6 13.Qe8+ Kf6 14.Qf8+ Ke6 15.Qe8+ Kf6 Game drawn by mutual agreement, perrypawnpusher - Joyus, blitz, FICS, 2007; and

9...Ne7 10.Qxe5+ Kc6 11.Qxc5 checkmate, perrypawnpusher - GabrielH, blitz, FICS, 2010 & perrypawnpusher - StockholmMoskva, blitz, FICS, 2010.

10.Rd1 c5


Black did better with 10...Ke7 11.Rxd4 d6 after which only an endgame swindle saved me in perrypawnpusher - richardachatz, blitz, FICS, 2010 (½-½, 71). Although the text is still good for the second player, richardachatz' King move "abandoning" the Bishop on d4 is also to be considered.

11.c3 Ne7

This is okay, but again 11...Ke7 could be considered.

12.Qh3


I was surprised, but also amused, to be a dozen moves into this offbeat line (rightly or wrongly) and still be in "book". It is sometimes very helpful to review and analyze games for this blog! 

This Queen retreat is comparable with the others that I had played previously:

12.Qh5 Qe8 (12...Kc7 13.cxd4 cxd4 14.Qxe5+ d6 15.Qxd4 Nc6 16.Qxg7+ Bd7 17.Bf4 Rg8 18.Qxh6 Qe7 19.Bxd6+ Qxd6 20.Qxd6+ Black resigned, perrypawnpusher - Lakritzl, blitz, FICS, 2009) 13.cxd4 cxd4 14.Rxd4+ Kc7 15.Qxe5+ Kd8 16.Nc3 Nc6 17.Qxe8+ Rxe8 18.Rd6 b6 19.Bf4 Bb7 20.Rad1 Re7 21.e5 Nxe5 22.Bxe5 Rxe5 23.Rxd7+ Ke8 24.Rxb7 Rd8 25.Rxd8+ Kxd8 26.Kf1 Black resigned, perrypawnpusher - tuffmom, FICS, 2010;

12.Qf4 Qf8 13.cxd4 Qxf4 14.Bxf4 cxd4 15.Rxd4+ Kc5 16.Bxe5 Nc6 17.Rd5+ Kb6 18.Na3 Nxe5 19.Rxe5 d6 20.Re7 Bg4 21.f3 Bh5 22.Rc1 Rhe8 23.Rcc7 Rxe7 24.Rxe7 Rc8 25.Rxg7 Rc1+ 26.Kf2 Ra1 27.Rh7 Rxa2 28.Kg3 a5 29.Rxh6 Bf7 30.Rxd6+ Kc5 31.Rd2 b5 32.Kf2 b4 33.Nb1 Ra1 34.Rc2+ Kd4 35.Rd2+ Kc5 36.Rc2+ Kd4 37.Nd2 Kd3 38.Rc7 Kxd2 39.Rxf7 Kc2 40.e5 b3 41.e6 Kxb2 42.e7 Kc1 43.e8Q Ra2+ 44.Kg3 b2 45.Rc7+ Kb1 46.Qe1 checkmate, perrypawnpusher - Xasquete, blitz, FICS, 2010.

12...Kc7


The text is an improvement on 12...Qb6 13.cxd4 cxd4 14.Qa3+ Ke6 15.f4 N5c6 16.f5+ Kf7 17.Nd2 Re8 18.Nc4 Qc7 19.Nd6+ Kf8 20.Nxe8 Kxe8 21.Qf3 Ne5 22.Qg3 Kf8 23.Bf4 d6 24.Rac1 Qa5 25.f6 N7g6 26.Bxe5 Qxe5 27.Qxg6 Be6 28.Qxg7+ Ke8 29.Qe7 checkmate, joev6225 - liverpool, GameKnot.com, 2006.

13.cxd4 cxd4



Black is still better, despite his shaky King, because of his extra piece.

Leading only to equality was 13...d6, although things quickly deteriorated: 14.Qc3 Nd7 15.dxc5 Nxc5 16.Bf4 b6 17.b4 Kc6 Black resigned, perrypawnpusher - tuffmom, blitz, FICS, 2010

14.Rxd4 N7c6
15.Qc3 Qf6


16.f4

Thematic, but wrong, as it should lose the exchange. I should have retreated the Rook first.

16...Nf7

My opponent missed 16...Nf3+ 17.Qxf3 Qxd4+ trading his Knight for my Rook. I think he was getting tired of all the attention that I was paying to his King.

17.e5 Qe7 18.b4 d6


Deciding to return the gambitted piece at precisely the point where his King might have begun to feel relief with 18...Kb8.

19.b5 dxe5 20.fxe5



20...Nfxe5

An unfortunate slip. After the game Rybka gave 20...Rd8 21.bxc6 Rxd4 22.Qxd4 Qd8 23.Qc3 bxc6 24.Nd2 Be6 25.Bb2 Qd5 26.Nb3 Rb8 27.Rc1 Rb6 and White is only a bit better (King safety)





analysis diagram





21.bxc6 Nxc6 22.Bf4+ Kb6 23.Qb3+ Ka6 24.Ra4+ Na5 25.Qc4+ b5 26.Qc6 checkmate

How odd that three Rooks, a Bishop and a Knight look on, uninvolved...

Overlooking

Chess can be so unfair. Overlook something when you attack, and you lose your advantage. Overlook something when you are defending, however, and you lose your game.

perrypawnpusher  - richardachatz
blitz, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Nf6

An earlier game between us had continued 4...Bc5 5.Bxf7+ and I had been fortunate to pull off an endgame swindle for a draw in 71 moves.

5.Nc3 Bc5


The Semi-Italian Four Knights Game.

6.Bxf7+

The Semi-Italian Four Knights Jerome Gambit.

6...Kxf7 7.Nxe5+ Nxe5 8.d4


8...Ng6

One of those reasonable moves that White can expect his opponent to play, even if there are no examples (until now) in the updated New Year's Database.

9.dxc5 Re8 10.Re1


If White is feeling "lucky" he could play 10.f4 directly, as 10...Nxe4 11.Nxe4 Rxe4 falls to 12.Qd5+ Re6 13.f5.

10...Kg8 11.f4 Qe7 12.e5

After the game Rybka pointed out that the e-pawn was still indirectly protected after 12.Be3, the move it preferred. After 12...d6 (if 12...Nxe4 comes 13.Nxe4 Qxe4 14.Bf2 winning Black's Queen for a Rook) 13.cxd6 Qxd6 14.e5 Qxd1 15.Raxd1 White would have only a small disadvantage.

12...Qxc5+


Planning to complicate things, but this backfires as he has overlooked White's responses. Pressure with 12...d6 against White's pinned e-pawn  was indicated.

13.Be3 Qb4 14.exf6 Qxb2 15.Nd5 Re4


Things have quickly gone from better to worse for Black, something that White could have demonstrated now with 16.Qd3, creating an X-ray attack through the Rook to the Knight on g6 and threatening checkmate in a way that only 16...Qf6 (losing the Queen) would prevent. Ouch!

16.fxg7

What's that old adage about, when you see a good move, sit on your hands and try to find a better one? 

16...Rc4


Black is still "complicating" things with his double attack on the pawn at c2, but he is still vulnerable to the move 17.Qd3, forking Rook and Knight.

Instead, I played what I hought was a great, killer move, but which was actually an error in "chess vision".

17.Ne7+

Planning, after 17...Nxe7, to fork King and Rook with 18.Qd5+, "overlooking" (in my mind's eye) that the d5 square would be protected by the Black Knight!

17...Kxg7

Lucky for me, my opponent also thought that I had played a good move. Rybka is reassuring that after 17...Nxe7 18.c3 the game is even, but I am very skeptical about that. 

18.Nxg6 Kxg6 19.Qd3+


Finally!

19...Kh5 20.Qf5+ Black resigned


Mate comes quickly.
