One thing I can say about Robo is that it seems to play gambits really well! It performs better at gambits than most of my other engines. I put them on reapairative database and build my own opening books with the engines. If 2.0 is better than 1.0 I'm really looking for some fantastick results as it is palying 25/10 in an extreamly strong tournament. I am looking foward to the results. 4cpu's and 1024 MB's we shall see and I'm betting it will do well!
