Why the black pieces on queen side?Rybka is going for king side attack.

Yeah, tied up on the queenside at that.

b4???is terrible move that locks the queen side, and white can go for an attack on black king side.

Expecting 26... Rc5 now, no big eval but some observers think White is ahead against an engine here because they don't evaluate a possible King attack?!:
