17...Qd8
Black can prefer the endgame: 17...Qxd2 18. Nxd2 Nb8 (The knight goes to the better place to the c6 square to attack the d4 pawn. This is a well-known knight manoeuvre. Every schoolboy and schoolgirl knows it) 19. Rfc1 Nc6 20. Nb3 (20. Bb5 Rec8 21. Bxc6 bxc6 22. b4 f6 (22...Kf8 23. f3 Bg6 24. Ra3 Rab8 25. Rb3 Ke7= 26. Rc5 Rb6 27. Kf2 Kd7 28.

23...h6

34...Kh7 35. Rc8 Rxb2 36. Qc1 Qa2!








   
37. Qh1!
37. Rxf8? is more spectacular, and after 37...Rxg2+ 38. Kh3 Qf2 39. Qe1 Black checkmates with 39...Rg3#.
37...Qa3
Or 37...Kg8 38. Qh3 Kf7 39. Rc7+ (39. h5 Qb1=) 39... Kg8 40. Rc8 Kf7, with equality.
