Drawing after 100 moves seems a bit quick if we are not getting any delayed time settings on the clock.  Especially when it was a mate in 5.  Either the draw rule should be looked at on this site, or there should be a small delay before the clock starts ticking.  I only lost two points, not a big deal, but giving me a draw on a clear win seems faulty.
