Could you not argue that stop & go would sometimes be the optimal play? Say if hero is sb, and its folded to late position for a 4bb raise. Prob get to take down a 9 blind pot 65% of the time, & double up 15% of the time. ie 65% of time villain doesn't hit & folds to our shove, and 35% of the time he hits a hand or draw & calls and we win 15% of the 35%.

But really, just reload. I never used to until I was down to les than 50 blinds, now I have auto reload on, thanks to someone on here telling me what an idiot I was if not doing so.
