In a surprising way White manages to achieve so pleasant position, especially as Leko's moves 19 and 20 were not a revelation to the chess world. 20...£g3 With the queens on the board Black takes risks of getting under a direct mating attack. However, in the endgame his chances for draw are rather illusory - the opposite colored bishops are of a little help for him there. 21.hg ¦fc8 22.f3 ¥g6 23.¦f2 h5 +0.85 [Shredder ssuggests instead abstaining from pawn advances while activating the black pieces as much as possible: 23...¦c4!? 24.¥f4 ¥c2 Pay the attention, the black bishop intrudes to the second rank where it disrupts co-ordination of white rooks. 25.¦c1 ¦ac8 +0.48] 24.¥f4 +0.52 [24.b4!? d3 25.¥e3 ¦e8 26.¥d4 +0.85] 24...d3 25.¥d2 ¦c2 The black rook on the second rank only imitates the activity, while white's pawn majority on the queenside is no laughing matter at all.
