With the idea of Rd1, trying to create pressure on the d-pawn. White immediately threatens to give Black a pawn weakness by cxd5, since the Queen and Bishop will be attacking the Bishop at a6 - though in many cases Black does fine despite the isolated pawn.
13. b4 Be7 (13... dxc4? 14. Be4
)
14. cxd5 Qxd5 15. Bxa6 Qxd1+ 16. Rxd1 Nxa6 17. a3 Nc7
after Nd5 Black's pieces find great squares.
13... dxc4 14. Be4 cxb3 15. Qd2 Nd7
16. axb3 Bb5 17. b4
A daring solution to Black's difficulties, sacrificing material in order to exploit the insecure position of White's king in the center.
17... Be7?! 18. Nd4! Bc4 19. Nc6 Qc8 20. Nxe7 Kxe7 21. Qd6+ Ke8 22. Bxa8! Qxa8 23. 
Better may be 19. Qxd8!? Raxd8 20. Bc2 Nd3+ 21. Bxd3 Rxd3 22. Nd4 Bc4 23. Bb2 a5
when it is not clear whether Black's two connected passed pawns are really sufficient compensation for the piece.
19... Qc7 20. Bd4 Rfd8 21. Qe3 Rd5
White has great difficulties despite his piece advantage.
22. Bxc5!?
Though this allows Black to gain a strong attack along the c-file, White has foreseen a forced draw.
22... Rxc5 23. Qe4 Rc8 24. Qxh7+ Kf8 25. Qh8+
Going for perpectual check. White has no better.
25. Bd3? Bxd3! (25... Rc1+ 26. Ke2 Qc2+ 27. Nd2 Rxh1 28. Qh8+ Ke7 29. Rxa7+ Rc7 30. Bxb5)
26. Qxd3 Rc3! 27. Qe4? (27. Qh7=)
27... Rxf3 28. Qxf3 Qxe5+ 29. Kd2 Qb2+
25... Ke7 26. Qh4+ Ke8 27. Qh8+ Ke7 28. Qh4+= f6?
Mistakenly trying to escape the draw, and that's all Timman needs.
29... gxf6? 30. Rxa7!! Qxa7 31. Qh7+

30. Rd1!

39. h3 Rh2 40. g4+ Kf4 41. Re4+ Kg3 42. Nf1+ Kf3 43. Re3+!! Kf4 44. Ra3!
Winning one of the pawns that really matter.
