ANATOLY KARPOV moved smoothly into the final of the Tilburg tournament by defeating Alexander Belyavsky by 1 1/2-1/2 . In the other semi-final, Vassily Ivanchuk and Alexei Shirov drew both games and must now decide matters with a quick-play shoot-out. Their first draw was the most thrilling game of the event so far.

The real fun began when Shirov played 17 . . . Nf5?] inviting a pawn fork with g4. This does not work at once since 18. g4 is met by Nd4, threatening Bxe4 or Nxe2+, but 18. Nc5 attacked a piece while making g4 a genuine threat. The next few moves piled up the tactics: 18 . . . e4 threatened Bxc3; 19 . . . Rac8 pinned one knight to the other; 20. g4 left three black men under attack; 20 . . . a5 threatened axb4 attacking three white men in exchange.

Ivanchuk threaded his way through the complications to emerge with two pieces for rook and pawn, with his own passed a-pawn looking likely to decide the game. Shirov gave up rook for bishop to eliminate the dangerous pawn and confuse the issue in his opponent's intense time-trouble. In the final flurry of moves, Ivanchuk permitted the exchange of all his pawns to force a draw.
