Some programs were compiled by inferior compilers. Movei was compiled by Visual C++6 except the first round when I used a version compiled by Dann Corbit but I found that there was a bug in time management with ponder on and I also wanted to change other things during the tournament so I used again a version that is compiled by Visual C++6 in the rest of the games. I was surprised to hear that Woodpusher was even compiled only by Visual C++5 The programmer did not buy better compiler because it was too expensive for him. I do not think that it is a fair advantage. Uri
