ROFL. Rybka has already grabbed it by the goolies at move 13.
AFAICT Getclub offered its goolies to be grabbed two moves before

Hardly - it was losing quite badly from move 13 still in the opening.

I keep noticing that very often a key developing move like in this case 
10. ... Be7 is never played by Getclub (or Be2 for white). It would have 
at least have had a s****ting chance with that line.

Perhaps you could tweak the evaluation to give a 20cp bonus to moves 
which permit castling to be played next (and also a bonus for castling). 
And also a bonus for moving minor pieces off their home squares.

AFAICT the least bad continuation after the disastrous

10. ... Nxe4

This could be a bug - a 6 ply search should reveal why this isn't a 
very good idea. And most engines prefer Be7 at a 1 ply search.

11. a3  d5
12. a3xN c6??

What is it playing at here? c6 is absolutely awful. Must be a BUG!

12. ... Bxb4 is obviously the least bad move by far!
Even the simplest material evaluation function would spot that move!

See above. It will gift its N for a P when it could have had 2P and 
freedom to castle into relative safety as compensation. This is still 
badly losing, but a lot better than the daft line it played.

Terminal decline sets in here. Rybka is already winning by miles.
