I had about 12 tabs open, half of which were beeping or flashing or something for me to give them my attention.
AWTA I'm in for a tourney with 30-minutes-a-side games (or 60). 10 is just too short - and chess games without time-limits are meaningless too.
Like I said. Chesscube lets you pick which ever time controls you want. Could also play Chess960 there if you want.
