X0 1.d4 X1 Nf6 X2 2.c4 X3 e6 X4 3.Nf3 X5 d5 X6 4.Bg5 X7 dxc4 X8

A secondary line of the Queen' s Gambit Declined [30]:

5.Qa4+ X9

[ Capablanca played 4...d xc4 in the game: 5.e3 X10 c5 X11 6.Nc3 X12 a6 X13 7.a4 X14 cxd4 X15 8.exd4 X16 Bb4 X17 9.Bxc4 X18 Qc7 X19 Janovski, D - Capablanca, Jose, R 1910.10.23 New York Manhattan CC [D30], 0-1]

5...Nbd7 X20 6.Nc3 X21 a6 X22 7.g3!?N X23

All this line is rarely played and this last move is probably a novelty. Of course, White plans Bg2 and 0-0, but his position seems rather breakable.

[ Has been experimented: 7.e4 X24 b5 X25 8.Nxb5 X26 Rb8 X27 9.Nc3 X28 Rxb2 X29 10.Ne5 X30 Bb7 X31 Speelman, Jon -Mult, Andrew J 1994, England ENG-chT [D30]]

7...b5! X32

Ivanchuk finds a good plan; Black holds an interesting initiative.

8.Nxb5 X33

The only move.

8...Rb8 X34

You may notice the likeness with the game quoted above.

9.Na7?? X35

Clearly a blunder. White' s army is dispersed on the Board and the a7-Knight threatens nothing clear! ... But Black has now to find an accurate disproof ......

9...Rb4 X36 10.Bxf6 X37 gxf6 X38 11.Qa5 X39

[ Is not convincing: 11.Qc2 X40 Bb7 X41 12.a3 X42 Rb6 X43 13.Bg2 X44 - +]

11...Bb7 X45 12.Bh3 X46 Qb8 X47 13.Qh5 X48 Ke7 X49

[ 13...Rb6 X50 was conceivable.]

14.d5! X51

The best choice in this position.

14...Qxa7?! X52

It is not an accurate move. Now the game may be a draw.

[ Very strong, but difficult to analize on the Board is the long line: 14...c3! X53 15.bxc3 X54 Rb6 X55 16.Nc6+ X56 Bxc6 X57 17.dxc6 X58 Rb5 X59 18.Qh4 X60 Rb1+ X61 19.Rxb1 X62 Qxb1+ X63 20.Kd2 X64 Qxh1 X65 21.Qb4+ X66 Kd8 X67 22.Qd4 X68 Bd6 X69 23.cxd7 X70 Ke7! X71 + - and Black must win!]

15.dxe6 X72 fxe6 X73 16.Bxe6! X74

Again White finds the only good defense!

16...Kxe6 X75 17.Qe8+ X76 Be7 X77

The only choice!

18.Qxh8 X78 Nf8 X79 19.Qg8+ X80 Kd7 X81 20.0-0-0+?? X82

A decisive mistake!

[ After 20.Qf7 X83 Qc5 X84 21.Rd1+ X85 Kc6 X86 22.0-0 X87 Rxb2 X88 23.Nd2! X89 +/= White has nothing to be afraid of!]

20...Ke8 X90 21.Qg4 X91 Qc5 X92 22.a3 X93 Rxb2! X94

This beautiful sacrifice is the key of the victory!

23.Kxb2 X95 Qxa3+ X96 24.Kb1 X97 Qb3+ X98 25.Ka1 X99 c3 0-1
