About these games

After 9.Bc4 Bd7 10.O-O-O the kings sit on opposite wings, and each side races to attack the other. White aims to open the h-file with h4-h5 and exchange the Dragon bishop with Bh6. Black uses the half-open c-file, usually bringing a knight to c4 and a rook to c4 with ...Ne5 and ...Rc8, then pushing the b-pawn.

Anand–Kasparov: Black stopped White's h-pawn with 12...h5. After 13...Nc4 14.Bxc4 Rxc4 Black had a rook on c4 and followed up with 15...b5 and 16...Qa5. White exchanged the dark-squared bishops with 17.Bxg7, and after 20.Rxd2 the queens were off with the score at 0.00. Black kept pressing with ...a5 and ...Be6 and opened the a-file. The turning point was 30.Nb6, which took the evaluation from −0.34 to −3.18. Black won the b-pawn with 30...Rxb4+, took on c2 with 31...Rxc2, and Black won.

So–Duda: White played 12.Kb1 and 14.g4 instead of h4. After 15.b3 b4 16.bxc4 bxc3 17.Qxc3 Black had given the exchange for play on the b-file and the long diagonal. White gave material back to trade queens at 28.Rxe5. After 33...Re8 the evaluation rose from +1.98 to +4.15. The score dipped from +6.06 to +4.87 at 42.Ne6+, but White pushed the b-pawn to b7 with 45.b7. The score reached +8.09 at 55.Rh5, and White won.
