ch-USA San Diego USA (2), 25.11.2004
[IM Greg Shahade]



1.e4 e5 2.Nf3 Nc6 3.Bb5 a6
Zilberstein feels comfortable with classical play against 1.e4, however playing in such a style against experienced Grandmasters often spells trouble. Let's see how Zilberstein handles it..

4.Ba4 Nf6 5.0-0 b5 6.Bb3 Bc5
Zilberstein plays the more modern version of the Ruy Lopez that has become popular lately. In the past, black would always place the bishop on e7 while defending with the Ruy.

7.a4 Rb8 8.c3
Preparing d4

8...d6 9.d4 Bb6 10.Na3 0-0
An interesting pawn sacrafice, however white will have to go through some contortions to keep the pawn.

11.axb5 axb5 12.Nxb5 exd4 13.cxd4 Bg4
Black is threatening to simply capture on d4 in this position, because after 14....Nxd4 15.Nbxd4 Bxd4 16.Qxd4 black can play 16...Rxb3.

14.Ra4
A funny, yet effective defensive move with the rook.

14...Re8
Note that black could not capture on e4 immediately due to Bd5. [14...Nxe4? 15.Bd5 ]

15.Bc2
Planning 15...Nxe4 16. d5, and suddenly the rook on a4 discovers the knight on e4! However this variation isn't so clear.

15...Qd7
Zilberstein prefers this over the more forcing Nxe4 [15...Nxe4!? 16.d5 Nxf2 17.Rxf2 Bxf3 18.gxf3 and black has compensation for the material. White will have two pieces for a rook whenever black decides to capture on f2, but black will have a pawn and white's king will be somewhat exposed. (18.Qxf3?? Re1# ) ]

16.Nc3
Bringing the knight to a nice central square. Finally things look very cozy for white, however black now has an annoying series of moves.

16...Bxf3!
Forcing white to ruin his pawn structure, as if the queen captures on f3, black can take on d4.

17.gxf3 Qh3
You'll think it's the 4th of July after the fireworks that are coming up here...

18.Be3
Ivanov must have felt very safe, as despite having some weakening of his king cover, black has no real easy way of bringing any pieces into the attack. Ivanov must have fell off his chair after the next move...

18...Re5!!
Wow! If white captures the rook with 19.dxe5 black plays 19....Nxe5 and there is no way to stop 20...Nxf3!

19.Re1
[19.dxe5 Nxe5 and despite white's extra rook, there is no stopping Nxf3]

19...Rh5
and suddenly black's rook is right in the thick of things.

20.Bf4
Only defense to Qxh2

20...Rh4! 21.Bg3
Threatening to capture on h4...

21...Nh5
But Zilberstein doesn't care! He finds a way to get another piece into the attack! What a nightmare for Ivanov, as what looked like an attack in which only blacks queen was taking part, suddenly black's entire army is joining the battle.

22.Re2
[22.Bxh4?? Nf4 and checkmate is forced on g2.]

22...Ne5!
This is getting ridiculous, the pieces just keep coming! Every piece except the rook on b8, is helping to attack Ivanov's king.

23.Rd2
Ivanov just has no idea what to do. Its very hard to move any of his pieces! [23.dxe5?? Nxg3 24.hxg3 Qh1# ]

23...Nf4! 24.Bxf4 Nxf3+
and Zilberstein wins Ivanovs queen. An amazing flurry of blows from Dmitry. Zilberstein takes his time finishing Ivanov off, but the result is never really in doubt.

25.Qxf3 Qxf3 26.Bg3 Rh6 27.Nd5 Re6 28.Ra3 Qh5 29.Kg2 Ree8 30.Bf4 c6 31.Rh3 Qg4+ 32.Rg3 Qh4 33.Bg5 Qxg3+
Dmitry decides that it's best to give back the queen to go into an endgame with the extra exchange.

34.hxg3 cxd5 35.exd5 Ba5 36.Rd3 Rxb2 37.Bd1 Be1 38.Be3 Ra8 39.Kf1 Bb4 40.Bg4 Rb1+ 41.Kg2 Ra2 42.Bf4 Ra3!
When you have 2 rooks and bishop and one rook and 2 bishops, it's usually a good idea to trade off the rooks if you are playing for the win. This way black has the only rook on the board.

43.Rxa3 Bxa3 44.Be2 Kf8 45.g4 Ke7 46.Kf3 Bc1 47.Bd3 Ra1 48.Bg3 Ra4 49.Bxh7 g6 50.Bh4+ Kf8 51.Bf6 Bh6
And after ...Bg7 the game is hopeless, so Ivanov resigned. 0-1
