My flatmate and I play every so often, and we started playing with a clock, otherwise we would stretch the game on for hours (which he has a problem with, not I). However, if we play with say 30 minutes each, we both usually end up using a lot of time in the early game, but by mid game we're already in overtime, and have to play rushed. Does anyone think that maybe 10-15 sec. per move would be better, or maybe just increasing our main time to 45 min (which we didn't seem to have problems with before.)?
