Speaking of saying you'll show them...Playing in small tournaments with my friends a lot of times it would come down to the showdown or a hard decision for them and they'd ask if the other person would show if they folded, or I would ask if they would show, if I was in the situation. I'd usually answer by saying yes no matter what and showing them. That way, if I have it they feel good about folding, if I don't, the next time I do have it they are sometimes more likely to call. If I asked and someone said they wouldn't show it, I usually put that on that they did have it, but I usually folded if I asked anyways, can't lose what you don't put in the middle...can't win much either.
