Timman vs. Ljubojevic

Timman vs. Ljubojevic
Linares 1985
Sicilian Defense, Najdorf Poisoned Pawn
1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6 6 Bg5 e6 7 f4 Qb6 8 Qd2 Qxb2 9 Rb1 Qa3 10 Be2 Be7 11 0-0 Ndb7 We have the same line of the Poisoned Pawn as in John Van der Wiel vs Lubomir Ftacnik, Arhus 1983. As was mentioned there, 11…h6, 11…Qc5 and 11…Qa5 are also playable. The move played appears most natural, but allows a surprising breakthrough in the centre.  12 e5 dxe5 13 fxe5 Nxe5 14 Bxf6 Bxf6
After 14...Bxf6
Currently theory gives 14…gxf6 15 Ne4 f5 16 Rb3 Qa4 as best, with an unclear position. However, Ljubojevic can hardly be criticized for the natural text-move. 15 Rxf6 gxf6 16 Ne4 Nd7? But this is definitely wrong. 16…Qe7 17 Qf4 Kd8 18 Nxf6 Nd7 19 Nxf7 Bxd7 20 Rxb7 is the best continuation, when White is slightly better. 17 Rb3 Qxa2 After 17…Qa4, 18 Qc3 (threatening 19 Ra3) 18…e5 19 Nf5 gives White an enormous attack, e.g. 19…Qc6 20 Qb4 Nc5 21 Ng7+ Kf8 22 Nxc5 Kxg7 23 Ne6+ fxe6 24 Rg3+ Kf7 25 Bh5#. It is now too late for 17…Qe7 in view of 18 Nc6! bxc6 19 Nd6+ Kd8 20 Qa5+ Nb6 21 Qxb6+ Kd7 22 Ne4! Rd8 23 Rd3+ Ke8 24 Qxc6+ Bd7 25 Rxd7 and wins.  18 Nd6+ Kf8  18…Ke7 fails to 19 Qb4 Qa1+ 20 Kf2. 19 Qc3
After 19 Qc3
19…Kg7?! Loses straight away. Black should have tried giving up a piece to safeguard his king, by 19…Rg8 20 Nxc8 Kg7 (20…Ne5 21 Rxb7 is very good for White). Then 21 Nd6 Ne5 22 Nf3 gives White a dangerous attack, but Black would still be fighting. 20 N4f5+ exf5 20…Kf8 22 Qb4+ mates. 22 Qh3!
After 22 Qh3! 1-0
1-0 Black cannot meet the threats of 23 Rg3#, 23 Qg4#, and 23 Qh5#.
