Overall scores after four rounds are as follows: Kramnik 7; Lautier 5; Shirov, Topalov and van Wely 41/2; Ljubojevic, Anand and Sadler 4; Ivanchuk 31/2; Karpov 3; Nikolic 21/2; Piket 11/2.
Here is Sadler's win against van Wely. In the Rapid games, players are given 25 minutes at the start, and an extra 10 seconds is added for each move completed. (In the blindfold games, the initial allocation is the same, but 20 seconds are added per move).
Sadler gained the advantage from the opening thanks to 11.e5, which denied Black the chance of freeing his game with e5 after the recapture on c4. White kept up the pressure on the Q-side and seemed to have a big advantage when he played 21.Nbxd4 threatening a multi-pronged fork with Nc6. Van Wely then found 21...Qe8 (!) intending to meet 22.Nc6 with Nc5.
After 22.b4, however, he tried to repeat the trick with 22...Rbc8 23.Nc6 Nc5, but Sadler gave up his queen for two rooks to increase his advantage. Black must have overlooked 29.Rxe4 (when Qxe4 loses to Neg5+), and the rest of the game was just a question of how long Black could resist against the white plan of doubling rooks on the seventh rank. It turned out not to be very long at all.
