Hi Bob, > I once played (using blitz, prior to Cray Blitz) in a human event, and I made > an ill-advised change between rounds.

Anyway it achieves a quite good rating on ICC compared to it real strength because most humans did not take the offered queen or other material. After fixing that bug Quark did play quite better against comps, but anyway it took a long time to get the same rating on ICC. I think most people think: "If the comp let me take the queen there must be something fishy... so better I do not take it". Greets, Thomas
