Catching Up on Round One in India

Some troubles on the tournament web site prevented me from posting Deepak Aaron’s game from round one. Bill Townsend told me he ran into similar problems with Deepak’s first round game. We both found some short game fragment that did not make much sense when played over.

For the first week of the event a promised download of the games in PGN format did not materialize. On the rest day today the games download came through, and I obtained the contest with Salgaldo Lopez this morning. This actual score does not resemble the game fragment found earlier, but it is logical. Here it is:

Aaron, Deepak (2288) - Salgado Lopez, Ivan (2626) [B86]

50th World Junior Championship, Chennai, India, 02.08.2011
Round 1

1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Bc4 Be7 7.Bb3 0–0 8.Be3,..

Known to theory but not exactly mainstream, nonetheless it is position full of complicated chances for both sides. Here is an example from a couple of solid internationalists of how this opening may be played:

Martin Gonzalez, Angel (2405) - Veingold, Aleksandr (2465) [B86]
Benasque op Benasque (6), 1993
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6 6.Bc4 Be7 7.Bb3 0–0 8.Qe2 Na6 9.g4 d5 10.e5 Nd7 11.f4 Nac5 12.g5 a5 13.a3 Nxb3 14.cxb3 Bc5 15.Be3 b6 16.0–0–0 Ba6 17.Qh5 Qc7 18.Kb1 Rfc8 19.Ka2 Qb7 20.Rhg1 b5 21.Rg3 Bxd4 22.Bxd4 b4 23.Na4 Rc2 24.Rh3 Nf8 25.Nc5 Qc7 26.Nxa6 Rxa6 27.a4 Rac6 28.Rhd3 Rc1 29.Qe2 Ng6 30.Qf2 Rxd1 31.Rxd1 Ne7 32.h4 Rc2 33.Qf3 Nf5 34.h5 h6 35.gxh6 Nxh6 36.Qd3 Nf5 37.Kb1 Nxd4 38.Qxd4 Qc5 39.Qd3 Rg2 40.Rc1 Rg1 41.Rxg1 Qxg1+ 42.Ka2 d4 43.Qb5 g6 44.Qe8+ Kg7 45.h6+ Kh7 1–0

8..., Na6 9.f3 Nc5 10.Qd2 a6 11.g4,..

The game is at a crossroads of the Scheveningen/Najdorf variations with opposite side castling and mutual attacks on the Kings. In other words plenty of excitement. The position is dynamically balanced at the moment.

11..., Qc7 12.g5 Nfd7 13.0–0–0,..

We begin to see that White has a position that is a bit looser than is Black’s. One thought is White might delay castling on the Q-side and try pushing forward on the K-side; 13 h4 Ne5 14 h5 b5 15 h6 g6; and it is hard to see how White can proceed quickly enough to cause Black problems making progress on the Q-side. The threats White can make are real, but the unstable situation of the White King likely means Black’s threats will take priority.

13..., b5 14.h4 Ne5 15.g6?,..
Offering a pawn that garners nothing significant. Maybe Deepak hoped for 15..., hxg6 16 h5? Black ignores the attempt at muddy the waters and continues his Q-side operation.

15..., b4 16.Nce2 a5 17.gxf7+ Rxf7

Black now has some advantage.

18.Nb5,..

Since 18 Nf4, fails after 18..., Nxb3+; this is what is left for White to do. The advantage for Black has increased. White now has to go all out on the K-side.

18..., Qb8 19.Bxc5 dxc5 20.a4 Rxf3

Black pockets a pawn, but that is not so important as getting the f-Rook into active play. Black has a material edge, but he needs to speed up his lagging development.

21.Rhg1 Rxb3

At first glance this a pseudo-sacrifice of the Exchange; really it is an operation eliminating some active White pieces serving to increase the importance of the extra pawn as well as solving the problem of developing the Black Q-side.

22.cxb3 Nf3 23.Qh6 Nxg1 24.Rxg1 Qe5

With some pieces off the White attack is not quite so fearsome.

25.Nf4 Bf6 26.Nd3 Qh2

A resource that had to be foreseen when making the capture on move 21. The attacking chances for White are fast disappearing leaving him the difficult prospect of conducting the late middle game with Knights versus Bishops while a pawn down.

27.Qe3 c4?!

Even Grandmasters, especially when they are still teenagers, can get carried away with tactics. The line 27..., Bb7 28 Nxc5? Qxb2+ 29 Kd1 Rd8+; promises only death and destruction for White. Stronger for White is 28 e5 Bxh4 29 Rf1 h6 30 Kb1 Bg5; but not enough to give White much hope in the ending after 31 Qf2 Qxf2.

28.bxc4 b3

The GM sets up mating threats, one more problem to keep White busy. The trouble is after the next move, the best Black can do is trade Queens and go into the ending. It is won for White, but 27..., Bb7; would have been a much shorter route to the same goal.

29.Qf2 Qxf2 30.Nxf2 Bxh4 31.Nd3 Bb7 32.Rg4,..

The two connected passed pawns Black has in hand likely win no matter what. More resourceful is 32 Kd2, then 32..., Bxe4 33 Rg4 Bxd3 34 Rxh4 Rd8 35 Ke3 Bf5 36 Nd4 Kf7 37 c5, offers some hope, but is probably still lost after 37..., g5. The “passers” are too big a problem to overcome in the long run.

32..., Be7 33.Nc7 Rc8 34.Nxe6 Rxc4+

With the Black Rook going to the 2d rank further resistance is becoming hopeless.

35.Kd2 g6 36.Rg1 Bxe4 37.Ne5 Rc2+ 38.Ke3 Bd5 39.Nd4 Rxb2 0–1

There are too many passed pawns now, and Deepak resigned.

Play resumes tomorrow, more then.
