No, it's actually really close. I set rybka 2.2 to 1200 ELO and black/white wins bout 50/50 over 20 games. I ran at full strength twice and white won both times, but it takes a lot longer to run obv.
The idea I use with white is to weaken his queenside by sacking my knights and one or two bishops so I can get a rook or my queen on to the a rank behind his pawns, but even then it isn't trivial because the threat of pawn promotion is always very real.
Rubka goes for wayyy more complex patterns. It mostly seems based around forming a hole in the middle of his pawn structure, forcing a ton of moves whilst taking three or four pawns for each piece sac'd.
I imagine that you could tweak the computer's scoring system to improve it's play as black (and white).
