Yes, that was the exception I had in mind :-) > As for the KGS events, I have considered alternatives. > > I could do the draw myself.

I don't mind last minute changes to the time control because kgs-gtp takes care of that (but maybe that's different for other programs?). Does kgs support McMahon? It would be nice to reduce the number of unbalanced games. I think even Swiss could be ok, if only the pairing was somehow a bit smarter...
