Actually what I said in 4. does not clash with 1 and 2. Let's call version 1.0.1 A, 1.0.5 B, 2.0.2 C and 2.1.0 D. If (ad) reach the same position but d finds it faster that could be due to optimization. In almost ever tournament a and d finish within 1.5 points of each other.. -/+. Same can be said of versions b and c. While this proves nothing, and I have said I hope it is not the case, in fact it could be a fact. Note it _could_ be a fact. I have _not_ stated anything concrete. When I read the previous post, it got me thinking so I ran a few tests and to my surprise it was correct. Nothing more. I find it odd, but it could be nothing more than a mind trick. I read it, so I was looking for pre-arranged results... When everyone was stating 1.0.1 was stronger than 1.0.5 I ran my own tests and found them false.. atleast on my machines.. I hardly ran enough games to prove anything concrete. Peter.
