Great results. What are time controls? It may be that rybka does not improve against fritz9 from original beta, but does improve against other engines. Here are my very preliminary results with 40/4 repeated blitz. Various rybka betas playing fruit 2.2. using noomen test set rybka beta 10d 10-14 rybka 10d (optimistic) 8.5-14 rybka beta 1 8-14 rybka beta 10d(ultrasolid 7.5-13 I'll wait till n gets to 100 for each engine and report back. Jim could you keep giving us regular updates on your tournment (i envy the fact that you have two good computes that you can dedicate to chess play) +30 if it holds, would be a great improvement in only two months best joseph On January 17, 2006 at 14:13:48, James T.
