That's a bad example. The case you're refering has a probability of 1,3ยท10^-17 % (Tooooo small), while in the case of openings Deep Sjeng for example would possibly have at the best case 2-3 times a bad opening at 76 rounds while Comet in the worst case 6-7. So it's not so big difference between the advantage of Sjeng against Comet. Although i agree that moves like 1.a4? 1.Nh3? should be avoided in matches between the top engines. > >more rounds is better. 76 is nowhere near enough. > >But run the event however you want.
