White gets two connected passed pawns. White can achieve this with Rb5, but must keep an eye on the e-pawn. This move is essential, as you will see later. This is the best White could hope for, but it is a win because Timman has positioned his king properly. The king needs to race to the assistance of the pawns, but cannot get to the queenside in time.
Absolute precision is required.
The endgame is winning, as the White king cannot get to the kingside pawns. The usual kingside targets are exposed, but there is plenty of defense. The flashpoint at f7 is guarded by king, queen, bishop and knight. The proud pawn at g6 has two supporting anchors. The rook at c8 can come to e8 or f8 to deal with attacks on the files.
