Position From The World vs. Timmerman

In a previous post I wrote of beautiful, though unplayed, variations in correspondence chess games. An example of this comes from the game between Gert Timmerman and The World Team at chessgames.com:


Position after Black's 37th move

Here the World Team played 38 h4, and here is analysis from Rybka, probably the strongest chess program: (34-ply) 38.h4 Kf6 39.Rf1 Ke6 40.f5+ Kd6 41.fxg6 Kxc5 42.Rf7 Ra8 43.g7 Rg8 44.h5 d4 (0.93)

In this line White leaves a rook en prise.

In the actual game, though, Timmerman did not play 38. ... Kf6 but 38. ... Ra6
