I think that is a bad idea if it is a feature the users would like. There are a lot of people doing these automated computers tournaments, and engines not resigning is a real waste of time. It is true that occasionally a point will flip here and there because of some bug, but Crafty is at a level where most of these silly bugs should been have eliminated long ago. Spending a lot of time hoping for a bug in the opponent is pretty lame. Besides if you don't resign, why should any body else resign? It will all be one big waste of time, much better to get on with the next game.... I guess people should keep a history of what programs refuse to resign, and then never resign against them either, to give them a taste of their own medicin. -S.
