Pieces and Pawns En Prise

Playing through a few of the top boards from each round at the World Open, there were a few games that caught my eye.

First up, Adams – Ehlvest, from round 4.

(FEN: r4rk1/4pnbp/2pp1pp1/Pq6/2NPP1b1/P4N2/1B3PPP/2RQR1K1 w - - 0 18)

Ehlvest had just sacrificed a pawn on a5 (16…a5 17.bxa5 Bg4), and probably was banking on some loose pieces in White’s camp to recover it. It does look like the Nc4 is a bit overloaded, having to watch over the Bb2 and the pawn on a5, while the pin from the Bg4 might also be annoying with …Ng5 on tap.

Adams’s next move was a bit confusing at first, but there’s a reason he was consistently in the top 10 of the world. He played 18.h3!, and after 18…Bxf3 19.Qxf4 d5 20.exd5 cxd5, the position in the diagram below was reached:

(FEN: r4rk1/4pnbp/5pp1/Pq1p4/2NP4/P4Q1P/1B3PP1/2R1R1K1 w - - 0 21)

White seems to have gotten himself in a bit of a pickle here, as the overloaded knight is now under attack. White’s next of 21.a4 makes some sense, but after 21…Qb7, it still looks like trouble – the knight is safe for the time being, but …Ng5 ends the pin on the d5-pawn, and playing 22.h4 is too slow because then Black just needs to guard his queen (with 22…Rfb8 for example), and then both minors are hanging. So what to do?

Adams uncorked the brilliant 22.Ba3! at this point (although the whole idea had to seen with 18.h3), seemingly ignoring the threat to his knight. After 22…Ng5 23.Qe2, the main line must be to take the knight, but Ehlvest found it didn’t work and played 23…Re8 instead. After 24.Rb1 Qa6 25.Nb6, White emerged a pawn up in the endgame and won without too much more trouble.

But what happens if Black takes the knight?

(FEN: r4rk1/1q2p1bp/5pp1/P5n1/P1QP4/B6P/5PP1/2R1R1K1 b - - 0 24)

After 23…dxc4 24.Qxc4+, Black has three reasonable moves, none of which seem to work:

How Can You Falter, When You’re the Rock of Gibraltar?

I’ve got a backlog of posts to add now that the tournament in Gibraltar is over, so this will be the first of a few before I start my next event in Cappelle la Grande (France) on February 13th.

The Gibtelecom Masters finished yesterday, and I ended up with 6.5/10. Not a bad score point-wise, but I didn’t play up to my expectations or my rating – I lost all the points I had gained in Sevilla to start off this trip. I’ll cover the first 6 rounds in this blog before wrapping up the tournament in a later post. Although 2 Americans tied for first (GM Gata Kamsky and GM-elect Alex Lenderman), neither was involved in the playoff (the top 4 on tiebreaks had a rapid playoff for the title). Emerging from that fight was GM Michael “Mickey” Adams of England. Mickey was once a perennial top-10 player – and one of the “Linares guys” according to Kasparov – but he’s slipped a bit over the past few years and I think this was his biggest tournament win in a few years.

In the first round, I won as black against Rafael Montero Melendez, a 2248 FIDE rated player from Spain. As though it’s an unwritten rule for my first-round pairings, he played the Exchange Slav against me. I’ve played the Slav for about 3 years now, and I face the Exchange Variation in about 1/3 of my games with it. After the game, I checked the database to see what the average incidence of an Exchange Slav is amongst games that fall under the ECO codes D10 to D19 (the range for all the variations of the Slav). As it turns out, in my database, it’s about 1 out of every 7 games, so either I happen to be playing a lot of opponents who normally play the Exchange, or they’re afraid of me and try the Exchange in the hopes of a draw.

In any case, I was not ready to call it a day after seeing 3.cxd5, and we reached a position after 13 moves that was decidedly unlike a normal Exchange Slav:

(FEN: rn2kb1r/1p3ppp/p1b1pn2/q2p4/P2P1B2/1RNBP3/4NPPP/3Q1RK1 b kq a3 0 13)

I had gone an early pawn-hunting expedition with my queen, playing …Qd8-b6xb2-a3-a5 (he had prepared the pawn sac idea, as he blitzed through that phase of the game), and now I returned home with 13…Qd8!?. I came up with this move after thinking for about 18 minutes. The idea is to play …Bd6 to exchange off White’s dark-squared bishop, as that would both clear the way for kingside but also relieve some of the queenside pressure I faced.

13…Be7 is also reasonable, but I rejected this based on a miscalculation in a long variation. After 13…Be7, one line I looked at was 14.Qb1 0-0 15.Rxb7 Bxb7 16.Qxb7 Nbd7 17.Bc7 Qb4 (the only safe square) 18.Bxa6, to reach the following diagram:

(FEN: r4rk1/1QBnbppp/B3pn2/3p4/Pq1P4/2N1P3/4NPPP/5RK1 b - - 0 18)

Now, in my head, I continued 18…Qxb7 19.Bxb7 Ra7 20.Rb1, and I didn’t see a good way to extricate the rook, noticing that the rook is trapped after 20…Ne8 21.Bb8. Unfortunately, there are two mistakes in this long line from the Black side – for one, after 21.Bb8, while it’s true that Black’s Ra7 has no safe square, Black has the simple 21…Nxb8 to save it! Also instead of 18…Qxb7, Black can play 18…Bd6 with a clear plus. White has other ways of continuing after 13…Be7, but since this line doesn’t work, my idea with 13…Qd8 was probably not the best one.

After 13…Qd8, the game continued 14.Qb1 Bd6 15.Bxd6 Qxd6 16.e4 dxe4 17.Nxe4 Qd5 18.Nxf6+ gxf6. White is still down a pawn, but Black’s kingside has been opened up, so his king probably won’t find shelter there. The center has also been opened up a bit, so Black has to be careful about keeping his king on e8 as well! Finally, Black’s still not properly developed, as after 18 moves, all I had to show for my efforts was that I had moved my queen and bishop off their original squares. White had definite compensation at this point, but I managed to outplay him in the ensuing complications, and he threw in the towel 10 moves later when he had shed a couple more pawns to no avail.

I drew the following day against IM Kenny Solomon (South Africa). This was pretty disappointing, since I had achieved a completely winning endgame only to throw it away with two hurried moves. The following day, I drew as black against FM Guillaume Camus de Solliers (France), in a game where my opponent played a rather safe line of the Meran, and I didn’t get any real winning chances.

Then, in the 4th round, I had the white pieces against Yves Duhayon (2241, Belgium). I haven’t played 1.e4 in a long time, but for this game, I decided to go after his Ruy Lopez and I achieved a clear plus. Unfortunately, in the following position, after I had played 21.Qd2-c2, I walked into a very nice drawing combination.

(FEN: 4rqk1/p1p3b1/b1p1r2p/3pN1p1/N2Pn3/7P/PPQ2PPB/R3R1K1 b - - 8 21)

I could have immediately sacrificed the exchange on e4 with 21.Rxe4 dxe4, and then played 22.Qc3 to cement my control over the dark squares. White threatens 23.Nc5 and various knight forks all over the place while Black’s rooks don’t have any good open files. As Kasparov would say, the quality of his pieces more than compensates for the material disadvantage.

Instead, I decided to play 21.Qc2, thinking that I would have time to take on e4 later if need be, and I might prefer to keep the material and kick the knight with f2-f3 instead at some point. Kudos to him for spotting a tactical resource that I just wasn’t looking for.

He played 21…Bxe5 22.Bxe5 Rxe5! 23.dxe5 Bd3!!, which forces a draw. The problem is that if I take the bishop with 24.Qxd3, he has 24…Qxf2+ and there is no safe square for my king. If I play 25.Kh1, he has 25…Qxe1+! 26.Rxe1 Nf2+, picking up the queen; 25.Kh2 allows 25…Qf4+, and now if 26.Kg1, Qf2+ repeats while 26.Kh1? Nf2+ is even worse. Finally, 25.Kh2 Qf4+ 26.g3 escapes the knight forks, but costs White his queen after 26…Qf2+ 27.Kh1 Nxg3+.

I refused the bishop and so avoided any knight forks with 24.Qxc6, but after 24…Qxf2+, there was still no good way for me to avoid a draw in the end. Black’s attack is quite strong, so I had to force a repetition on move 37 with checks on g6 and h6.
