A s I write, Kasparov leads Smyslov in ra.their Candidates' final match at Vilnius by the score of 7-4 and now needs a mere 1 '/2 points to ensure his meeting Kar- pov later this year in the world champion- ship. What is noteworthy about the Vilnius contest is that Kasparov has gone even fur- ther in his espousal of the highly positional style of play which characterised his victory against Korchnoi. There have been very few tactical fireworks, just highly polished technique from the younger man, really beating the veteran ex-world champion at his own game. I have the feeling that this trend on Kasparov's part will continue, possibly even intensify, until he has en- countered Karpov. The same pattern emerged with the fiery Alekhine (Kasparov's model) who suppressed his tac- tical imagination until he had safely dispos- ed of Capablanca. Only then did he return to the risk-loving adventurous style which was his first love. Kasparov — Smyslov: Candidates' final, 9th game; Cambridge Springs Defence.

Nd7-b6, but the complications which then arise have been worked out to favour White in the period since Alekhine invented the concept in 1935: 8 ...

It is possible that Black should retain the possibility of ... b6, giving up one pawn to liquidate the entire Q-side, thus con- fining his defensive problems to the other side of the board. 20 Be2 Be6 21 Rbl Re7 22 Rhd1 Rae8 23 Rb2 Bc8 24 Rbd2 Rd7 25 Rxd7 Nxd7 26 g4 Nc5 r Be3 Nd7 28 g5 White has excellent winn- ing chances, based on his B-pair and mobile K-side pawn majority, which will eventually fur- nish a dangerous passed pawn. 28 ...

The position, however, remains tight, especially because the N remains passive.' 33 Bc3 Rxdl 34 Bxdl Nd7 35 f5 Bc4 36 h5 (Diagram) White's pawns sail forwards in majestic and impressive fashion.
