The number of games that you need is not constant and is dependent in the result. I guess that everyone will agree in cases that original nimzo8 is losing 50-0 against Deep Fritz when new Nimzo8 is winning 50-0 against Deep Fritz that 50 games is more than enough to be convinced that the new setting is better. I do not think that you can claim that the new nimzo is better than the old nimzo based on only one opponent and I think that you need to test both nimzo against many programs because it is possible that one setting is 30 elo better against Deep Fritz but 30 elo worse against another program. 30 elo difference is a small number and 50 games are usually not enough to know which version is 30 elo better. You can have a big probability to be wrong if you try to claim things like it based on only 50 games(I guess that if the difference is 30 elo then you have probability of about 30-40% to be wrong in saying which program is better based on 50 games of both programs against Deep Fritz but I did not calculate it) Uri
