Zappa - Rybka 4 day game

[Andrew]

I was away over the long weekend so left the two engines to play each other
in this game with 2 days total time each from a chosen start position.

This is with a single CPU at 1.9 GHz and 256 MB set for each in the Fritz
10 interface, all TBs up to 5 men, no books or learning.
I haven't looked at it enough to see where it was lost, however at least
up to 6. c3 is theory in "The Fascinating Kings Gambit" by Johannson, but
he and Rybka prefer 4. d4
