At 40/2hr?  Disasters.  The micros played in things like the US Open, the
World Open, and local events that had a GM here and there.  No competition
whatsoever at 40/2 back then from the micros...  Which is what made Deep
Thought's performance so startling to everyone.

Several of us beat a GM here and there, but not regularly and rarely more than
once in a single event.  Until Deep Thought.
