no2 has happened to me...I think at low levels it is pointless for 2 reasons.
1) in order to alter your table image significantly you have to b playing against opponents who will interperate the infomation correctly.
2) You are showing your mistakes for all the world to see. You may have played horribly but caught a lucky card and won.. but you don't see it that way. Also, what will you want to show? quads and royal flushes? the problem is that mostlikely you played the hand in a predicatable fashion.. so a more thnking player might start raising you more and then folding, figuring that you will only keep betting with a decent hand.
Well you could look at the HH but not no more on UB witch was sad, now how i can find out your hand range ..........Of course another thing to remember is that at showdown, all of the thinking players are using HUDs anyway.. so they will be displaying your cards from the HH.
I agree with mucking 99 percent of the time. The only time I may consider showing is when you get a run of cards without callers for two or three straight hands. Possibly if someone asks and they have shown in the past out of respect but thats a rare occasion.
i think this sums up the best way... And thinking on it, that is when i show..Muck Muck Muck
Only time you don't Muck is when you feel it's time to reinforce or change you Table Image.
No Exceptions.
Thats it ..........
Well maybe one exception.
Heads up
Do what you need to do to mess with there minds.
