You weren't the only one playing it. That is the purpose of making it a web-based facility... IBM uses it at lots of places at the same time. < 1 second per move + web lag + other users make the time stretch out. When I asked Hsu about it, he responded that it was simply set up as a demo for IBM to use as a P/R tool, and wasn't designed to _really_ play a serious game of chess (IE how serious could it be with no possibility of detecting draw by repetition for one thing?) If you want more details, Hsu doesn't seem to avoid answering questions so long as they are fairly precise (IE no "tell me everything there is to tell about DB") BTW, the 'web-based' explanation came from Hsu. Not from me.
