In case you wonder, I think that I might be of some help. You listed almost all the available versions up there, almost all but one: Ruffian Leiden 2003 BTW, the version that won the Dutch Open 2003. And that one is the strongest of all, at least in my testing: more than 5000 games at different although fast time controls (longest was G/45, played on two fast machines: P4-2.4 and Athlon 2800+ Tbred). Of course, I am aware of some other credible data (cf. Sarah Bird, for example) that point in a different direction. However, none of the testers has done so much testing with the Leiden version which is simply neglected for reasons unknown to me. Even the mammoth effort of Leo Dijksman, a person of absolute integrity, has somehow "missed" to test the Leiden version. Most probably due to the _unnecessary_ and very much _premature_ hype about Ruffian 2.0.0 (almost untested by me, at least). I am as sure as one can reasonably be that the Leiden version of Ruffian would perform about 30-40 Elo better than _any_ other version of Ruffian in SSDF testing and that it should place about as high as CM 9000.
