Houdini at depth 31 play Re3, valued position +1.35 and expect answer Rac8.

After long calculating Rybka at depth 26 sees Rac8 failing and switch to move Bc6 with value -2.00 and expect g6.

Houdini thinking otherwise - b3, +2.70 and expected answer Kg8.

So, 2.70-1.35=+1.35 gap in one move for Houdini.

Can anyone Rybka-s expert/fan explain me where Rybka see failing? Because 1.35 gap in one move is to much for me at this position.
