Klip,H
From Mondariz, 1996.  Black is intent on attacking on the Kingside, his Bishop on g3 serving a sinister purpose.

WHITE TO PLAY AND WIN!
Degree of difficulty: medium to hard.

France, 1999.  Another sharp position, this time featuring opposite-side castling.  In such positions it usually comes down to who is the quickest in the race.  One move can make all the difference…

Buenos Aires, 1993.  Oscar has been keeping up the pressure but his resourceful opponent has been containing it.  However, whenever the King is still stuck in the centre, one must never be too confident…
