Does that _really_ show >which of the two should have won the tournament??? Well there are several reasons to do it, one is simply to find a quick way to resolve the situation. For all involved it's not ideal to postpone everthing to the next weekend and play round robin 45 10, again. Also one could argue, that if the engines are equally good at 45 10, then the some kind of second order measurement must be done, ie. blitz strength. >>>Other points to ponder: >>> >>>1. too many rounds.

I think the more games the better if you are interested in finding the strongest engine. Being strong against weaker engines also count. >>Also, consider that major swiss events typically have fewer than log2(entries), >>so even fewer rounds than log2(entries) works. > >no doubt at all there.
