By the way, does the Rybka 2.2n2 picture mean that it wasn't R 2.3.2 which won the competition, but the old 2.2 version?


The Rybka 2.2n2 picture (rybka_916kns.jpg) apparently was taken at the end of Round 9 (against Scorpio)
It seems that the Vasik team previously found a hash bug and preferred to revert from 2.3.2 beta to 2.2n2 Very Happy


It does not make sense because 2.2n2 also has a hash bug and here is the proof

Vasik knows about it and he thanked me for telling him about that bug in the old rybka forum

see the following thread
