The knight looks beautiful on c6, constricting Black's rook like a fast food lover's arteries. White's rook controls the open file and his king is better centralized too, but despite all this White's advantage is minimal at best.

A little startling, perhaps, but very good!

[34...g6! 35.Kxb4? Rb6+ 36.Rb5 Rxc6 37.Kxa4 Rc2 favors Black.]

Ivanchuk holds the draw without much trouble, but 34...g6 would have been no trouble at all.

41...c5 42.h5 Rh4 43.h6 Kc6 44.Kc3 Kd5 45.Rh8 Rh3+ 46.Kd2 Kc6
Correctly rushing back to the corner, so that after h7 White's rook will have no winning follow-up.

[47.h7 Kb7 is an immediate draw, because even after White wins the c-pawn (by bringing his king to g2, then to g6, then to d6/d5) Black holds. He leaves the king on b7 and the rook on the h-file (except to check White's king away when it defends the h-pawn) and that's that.]

47...Kb7 48.Kf2 c4 49.Kg2 Rh5 50.Kf3 Rh4 51.Kg3 Rh1 52.Kf4 Rh2 53.Ke5 Rxb2 54.Kd4 Rb6!
The Vancura draw. Black attacks the pawn on the 6th rank while leaving his king on b7, only reacting to two things. First, if White's king protects the pawn, it gets checked away. Second, on h7, Black plays ...Rh6 followed by ...Rh1, leaving the king on b7 and a7 and checking away White's king whenever it protects the pawn on h7.
