Bootlegging

Raymond Keene

This week, two interesting games I played in a recent tournament in Chi- cago.

Day-Keene: Chicago, March 1985; Caro-Kann. 1 e4 c6 2 Nc3 I had expected 2 d4 d5 3 e5!? Bf5 4 Nc3 e.g. 4 . . e6 5 g4 Bg6 6 N.ge2 Bb4 7 h4 Be4 8 Rh3 h5 10 Bg5 0b6 as in Day-Vranesic, Canadian championship 1981. Here BCO gives 11 a3! 'better for White'. Therefore I wanted to try 4 . . . Qb6!? 5 g4 Bd7 6 Na4 Qc7 7 Nc5 e6 8 Nxd7. Vclimirovic-Kasparov, Moscow Interzon- al 1982, proceeded 8 . . . Nxd7. My new idea was 8 . . . Qxd7 intending a quick . . . c5 in conjunction with . . . Nc6. The Black Ng8 can go to e7 to hold up White's thematic plan of f2-f4-f5 which caused Kasparov trouble in his game. 2 . . . d5 3 Nf3 Bg4 4 h3 Bxf3 5 Qxf3 Nr6 6 b3!? This must be a novelty though, it's quite in Day's inventive style. I anticipated White to follow up with 0-0-0 and then g4-h4-g5-h5, trying to mince my K-side in co-operation with the Bb2. 6 . . . e6 7 Bb2 Nbd7 8 exd5? From now on White starts to play feebly. He should maintain the tension with 8 0-0-0 although . . . Bb4 is satisfactory for Black. 8 . . . cxd5 9 Qg3 With threats of Nb5, also trying to impede the development of Black's dark-squared Bishop. A broadly similar concept was seen in Smyslov- Botvinnik (first match game, 1958 world cham- pionship), which followed this game for the first five moves and then varied with 6 d3 e6 7 Be2 Nbd7 8 0g3 but then Botvinnik proved that 8 . . . g6! is possible, even with 0-0 already played. Black developed the Bf8 on g7 and went on to win. So in this game I always had . . . g7-g6 in mind as a reserve development. 9 . . . a6 10 0-0-0 Rc8 11 d4? A losing positional blunder which weakens c3 and blocks his dark- squared Bishop. Perhaps White was bothered by distant threats of . . . d5-d4 from Black. Any- way, 11 Rel is superior. 11 . . . Qa5 Black swiftly works up an annihilating initiative. 12 Kbl Ba3 13 Bal Bb4 14 Rd3 Of course, 14 Qxg7 loses a piece to 14 . . . Rg8. 14 . . . 0-0 15 Qe3 The threat was 15 . . . Bxc3 and 16 . . . Ne4. 15 . . . Re6 16 Ndl Ne4 Tempting but wrong is 16 . . Rxc2 17 Kxc2 Qxa2+ 18 Bb2 Rc8+ 19 Rc3! Bxc3 20 Nxc3 Ne4 21 Bc4! and White wins, since 21 . . Nxc3 fails to 22 Ral. 17 c3 Be7 18 h4 Trying to play Rhl-h3 with triple lateral protec- tion to c3. 18 . . . b5 The rest is automatic. White's Q-side pawns are structurally dead, and Black also enjoys the luxury of having the White K as an additional target. 19 b4 Qc7 20 f41 didn't understand this, but it is too late to make any

Keene-Martinovsky: Griinfeld.

d4 Nf6 2 c4 g6 3 Nc3 d5 4 N13 Bg7 5 145 A reliable system which I have used about six or seven times. I was also impressed by Karpov's win with it over Korchnoi at Phillips and Drew, London 1984. 5 . . . Ne4 6 cxd5 Nxg5 7 Nxg5 e6 Also possible is the gambit 7 . . c6!? 8 dxc6 Nxc6 9 e3 e5 10 d5 Qxg5 11 dxc6 0-0. Hubner had a rough time on the White site of this against Kavalek at Montreal 1979, so I had no reason to doubt that his subsequent try 12 h4! Qc7 13 Nd5 Qd6 14 c7 e4 15 Bc4 Qc5 16 Qc2 b5 17 Bb3 Qxc2 18 Bxc2 Re8 19 0-0 Bb7 20 Kbl , eventually won by White in 143 moves (Hubner-Ftacnik, Biel 1984), truly does represent a well-thought-out edge for White. 8 Qd2 exd5 Most theoretical texts regard this as equal, but in my opinion Black still has to contend with certain difficul- ties, e.g. a displaced K. Safer is 8 . . . h6 9 Nh3 exd5 10 Nf4, as in Karpov-Adorjan, Budapest 1973. After 10 Qe3+ Kf8 11 Nf4 c5! Black is OK. 9 Qe3+ Kf8 I love it when my opponent cannot castle. 10 Qf4 B16 11 h4 h6 12 Nf3 c6 Authorities differ on this position. BCO says 13 e4 dxe4 14 Nxe4 is slightly better for White, as in the game. Other books give 13 e4 Be6 14 e5 Be7 15 Bd3 Nd7 'equal'. I don't believe that at all. White can play g4-g5 or h5. Also 16 Qe3 intending Net-f4. Black has many difficulties to overcome. 13 e4! dxe4 14 Nxe4 Bf5 This looks plausible but loses by force. 14 . . . Qa5+ 15 Nfd2 Bg7 16 Bc4 is virtually winning, so the best defence is 14 . . . Kg7 although 15 Bc4! keeps White on top. 15 Nxf6 Qxf6 + 16 g4 Qe6+ Alternatively, 16 . . . Qe7+ 17 Ne5 0b4+ 18 Kdl Qxb2 19 Rcl Be6 20 Bc4! Bxc4 21 Rxc4 with an overwhelming attack. 17 . . . Bd7 allows!

18 0-0-0 or 18 Bc4. 17 Ne5! f6 Or 17 . . . Qd5 18 gxf5 Qxhl 19 fxg6. 18 gxf5 fxe5 19 dxe5 QxfS Or

19 . . . gxf5 20 Bc4 wins. 20 Qb4+ Kg7 21 0-0-0 This is crushing. No need to enter complications with 21 Qxb7+ Qd7 22 Qxc8 Qc7. Black now has to stop 22 Qxb7+. 21 . . . b5 22 Bd3 QxeS 23 Rhel Nab 24 Qg4 Qf6 25 Bxg6 Rfd8 Or 25 . . . Nc5 26 Bx2+ and 27 Qb4. 26 Re6 Rxdl+ 27 Kxdl Qxb2 Or 27 . . . Qf8 28 Bc2+ Kh8 29 Qd4+ Qg7 30 Rxh6+; 27 . . . Qxf2 28 Bf5+ Kf8 29 Rf6+ also wins. 28 1k2+ KM 29 QfS+ Black resigns.

Kasparov is said to be preparing actively for his rematch with Kasparov. His prog- ramme includes a match with Hubner at Hamburg in May' and another with Andersson later in the year at Belgrade.
