20...Qa8!
Defending the rook on d8 a second time, and threatening to simplify with 21...Nc5 and 22...Nxe4.
21.Qc3
Stepping off the d-file so that 21...Nc5? 22.Nxc5 bxc5 leaves Black with a weak pawn on c5.
21...Nb8!
But the second retreat does the trick. Black is threatening to win a piece with 22...Rxd1 23 Rxd1 Qxe4. Seeing no way to keep an edge once Black plays ...Nc6 and exchanges rooks on the d-file, Kasparov made a sham piece sacrifice leading to an immediate perpetual check draw.
22.Nf6+
After 22...gxf6 23.Qxf6 (attacking d8) 23...Rxd1 24.Qg5+ Kh8 25.Qf6+ White gives perpetual check.

10.Qd2!
Paradoxically, the way to achieve the best future for the bishop on c1...is to temporarily stalemate it! Michael Adams wants to put the bishop on b2, but the immediate 10.b3? runs into 10...Bb4 when Black wins the exchange. Therefore to prepare 11 b3 White defends c3 with the queen.
