Ivanhoe T57b is extremely strong, but not enough to bate Houdini 1.02. It seems very well tuned against DRybka4.

MIshas Mauler12T has got again a very decent result against such powerful opponent, with a huge speed handicap. In 8 cores computer (with hyperthread) its speed handicap against Ivan is 700%.
