I played 8 rounds without book, 10s for move in 2 CPU. Stockfish was impressive:

4   Houdini 3 x64    ½00½00½0 ½½01½0½0 ½½11000½ ********   8.0/24

It was never in danger of losing. Here's one stunning game. SF has minus pawn and negative score, but still won game by some inhuman manouvering with h pawn!
