Nothingness: The IYT time limit of 28 hours a move seems to work pretty well. I played a Jarmo tournament here with Fisher which added 8 hours per move which also worked well although when my opponent got down to 12 hours I did try using my time advasntage to move last thing at night hoping he had gone to bed. Not terrible sporting but as we are playing in an espionage tournament that has reached move 20 after 3 months I didn't have much sypmpathy!
