Vicary - Kelleher Marshall Thursday Rd 1

Elizabeth Vicary (2100) - Kelleher,Jeff (1999) [B31]
Marshall Thursday over 1600 tournament rd 1 17.05.2009
1.e4 c5
2.Nf3 Nc6
3.Bb5 g6
4.Bxc6 bxc6


4... bxc6 is pretty rare. I'm supposed to castle, then play Re1: 5.0–0 Bg7 6.Re1. Playing 6.c3? doesn't make so much sense, because it reduces white's options after 6... Nf6: 7.e5 Nd5 8.c4 is stupid if you've already played c3.

After 6. Re1. black has three main choices: 6... e5, 6... Nh6 (with the idea of ...f6 and ...Nf7), or 6... Nf6 (daring white to play e5 and c4) . 6... d6 isn't good because of 7. e5.

Against 6...e5, there is a fun-looking pawn sac, and I love fun-looking pawn sacs, especially, for some reason, when they start with b4: 7.b4 cxb4 8.a3 bxa3 9.Bxa3 Ne7 (9...d6 10.d4 exd4 11.e5) 10.Bd6 f6 11.c3 0–0 12.Qb3+ Rf7 13.Na3 compensation for the pawn (Timman)

6...Nh6 is ok but passive and white can just develop and attack the weakness on c5: 7.c3 0–0 8.h3 d5?! 9.d3 f6 10.Be3 c4 11.exd5 cxd5 (11...cxd3 12.Qxd3 cxd5 13.Bc5 +/= S.Rublevsky-Z.Hracek, Polanica Zdroj 1996.) 12.dxc4 dxc4 13.Na3 +/=

6...Nf6 is much more confrontational: 7.e5 Nd5 8.c4 Nc7 9.d4 cxd4 10.Qxd4 Ne6 11.Qh4 and now two lines:

b1) 11...d6 12.Bh6 Bxe5 13.Nxe5 dxe5 14.Nc3 f6 15.Rad1 Qc7 16.f4 exf4

Palliser calls this quite reasonable for black, although I like playing pawn-down-with-initiative positions, so I'm into it. He now gives the weird-looking 17.Re4? from the game E.Miroshnichenko-Bu Xiangzhi, Bled 2000 without comment, but doesn't this lose to 17...Qb6+ 18.Kh1 Qxb2? (white can't block/defend with 18. Qf2 because black trades queens and plays ... g5 to trap the Bh6) In the game, Bu Xiangzhi played 17... Rb8 and then white secured the pawn with 18. b3. Rybka (and I) prefer 17.Ne2 Qb6+ 18.Kh1 Qxb2 19.Nxf4 Nxf4? (19...Kf7! 20.Re2) 20.Qxf4 big threat: Qc7 +-

b2) Black can also prevent Bh6 with 11... h6, but doesn't this look like white is having all the fun: 12.Nc3 d6 13.Rd1 Bb7 14.Be3 c5 15.exd6 exd6 16.Qg3 Bxf3 17.Rxd6 Qb8 18.Rxe6+?

back to reality....
6.0–0 I was wondering if I should play 6. c4 to stop a later ...Ba6 and ...c4. It seemed too far away to deal with now.
7.h3 Rb8
8.Nc3 Qa5
I couldn't think of a good way to deal with black's threat to take a pawn: 9.Qe1 felt lame, and 9.Qe2? just sucks: 9...Bxc3 10.bxc3 Qxc3 11.Bd2 (11.Bg5 Rb2) 11...Qxc2. So I decided to solve my problem with some "positional imagination," which turned out surprisingly well:

9.e5! dxe5
10.Qe2 f6

Here, I played 11. Nd2 because I'm greedy, and was still thinking that maybe I wanted to play f4. (Later, it occurs to me that I'm playing against 2 bishops, and consequently shouldn't be trying to open the position, but common sense hasn't kicked in yet.) Rybka has a couple suggestions: 11. a3 (can someone tell me why?) and the excellent 11. Re1. I hadn't realized that this prevents black from developing the knight, but it does: 11.Re1! Nh6? (11...e6 12.Ne4 Ne7 13.Nd6+ Kf8 14.Be3 Nd5 15.Nc4 Qa4 16.Bxc5+) 12.Bxh6! Bxh6 13.Nxe5! fxe5 14.Qxe5 winning stuff.
11.Nd2 Nh6
12.Nb3 Qc7
13.Nxc5 Nf5
14.N3e4?! Nd4
15.Qd1 Ne6 [15...f5! 16.Ng5 h6 (16...Qa5) 17.Nf3]
16.b3 Nxc5
17.Nxc5 0–0
18.Qe2 Rd8

19.Bb2 The bishop doesn't have much to do here. I thought I was restraining ...f5 by putting pressure on e5.
20.Ne4 Qd5
This is a stupid move, because why do I think I'm going to play f4? I'm not, I'M TRYING TO KEEP THE POSITION CLOSED. It's very hard for me to sit and do nothing, my natural instinct is to open every position, but I clearly need to get a hold of myself here and not do anything stupid and irreversible.


oh look, a target! I love you, little target!

22.f3 Bb7

23.Qf2 Rbc8
24.Ba3 Ba8

big dilemna: take with the bishop or knight?

I saw this in the game: 25.Bxc5 f5 26.Bxe7 fxe4 27.fxe4 Qd4 28.Bxd8 Rxd8 29.Qxd4 exd4

this, or what's behind door A?

I figured this was good for me, but I thought Nxc5 was too. I sat there, frozen, thinking blank, terrified thoughts for a while, but then I wasn't any closer to making a decision, so I went for the simpler move.

25. Nxc5 Qd6
26 .b4 Bd5

27.c3 Ba8

28.Rd1 f5
29.Qe3 This is me, trying not to ruin my position before time control (move 30).

At the time I was cursing myself for allowing this, but it turns out to be bad. (hurray me for allowing it?!) The rest of the game is mostly played by my opponent, I just made the obvious responses.

30.dxe4 Qxd1

31.Rxd1 Rxd1+
32.Kh2 fxe4
33.Nxe4 Bxe4
34.Qxe4 Kf7
35.b5 Bf6
36. Bb4 Rd7

37.Qe3 Rc4
38.a4 Rdc7

worried about the c pawn?
don't be

39. a5 Bxc3
40.Bxc3 Rxc3
41.Qf4+ Ke8
42 .b6 axb6
43.axb6 Rb7

find the cutest win!

44.Qa4+! Kf7
45.Qd4! Rxb6
46.Qxc3 h5
47.Qc4+ Kg7
48.g4 hxg4
49.hxg4 Rf6
50.Kg3 Rf7
51.g5 Rf5
52.Qh4 Rf8
53.Qh6+ Kf7
54.Qh7+ 1–0

You may be right about 17 Re4?, but Palliser doesn't have to show a *win* for black in order to prove his evaluation.
This is just blindfold analysis, so take it with a grain of salt. After 17 Re4 Qb6+ 18 Kh1 Qxb2, perhaps white can get away with 19 Bg7!?
(a) 19...Nxg7? 20 Qxf6 is right out.
(b) 19...Qxc3 20 Bxh8 is problematic but hardly a forced win for black.
(c) 19...Rg8?! 20 Bxf6 exf6 21 Qxf6 (big threat) Bd7 22 Rxe6+ Bxe6 23 Qxe6+ Kf8 24 Qf6+ Ke8 25 Re1+ Kd7 26 Re7+ and mates.
(d) 19...Rf8!? 20 Bxf8 Qxc3 21 Bh6!? and who knows? (21 Qxh7 Kxf8 22 Rd8+? runs out of gas).
I'm sure Rybka will make mincemeat of these variations, but I had fun.

Hi Elizabeth,
In your analysis to 25. Bc5 f5, does 26. Be7 fall to a cute zwich, Rd7? 26...Re8 doesn't work (I think) because of Nd6, but if 26...Rd7, then 27. Nd6 Rc6.
Dunno, just some random ideas before bedtime.
P.S. How did you do in your game tonight?

Marc Widmaier said...

I'm silly, after 26. Be7 Rd7, you can play Nf6! Serves me right for analyzing at midnight.

hey, thanks Marc, I won. (HURRAY!!!)
