I voted "rarely", but it is closer to never...In a ring game, i have auto muck on 100% of the time, as I just don't fuss with it...

In a SNG, when it's HU, I will show a hand from time to time if I think I can mess with 'em a bit...

All in all, I think I am better off never showing...Maybe someday at the 200NL a case can be made, but at my limits (100NL and 1/2 LIMIT- 20 SNGs), I think never showing is a better option...Most the time when people show, it's just the ego anyway....
