re: Poker & Showing your cards sometimes pays off
I disagree Dorkus...
I do NOT show my hands while playing live except in one circumstance...playing heads up.
If you show a bluff after you win a pot while playing a heads-up match, or going for the top money in a tournament, you can have a great deal of impact in putting your opponent on tilt.
A recent example of this in my own poker games
was in a live heads-up match with a guy who I don't like very much...you could call it a grudge match. I was down chips by a 4:1 margin (he had 4 times as many chips as I did). Within the next 6 or 7 hands I went all-in twice after the river with a queen high one hand and an unpaired 87 offsuit on a dangerous board while sensing weakness and he folded both times.
I showed these hands to him and each time he got a little angrier, the second time he could not believe I put all of my chips in with absolutely nothing (8 high basically).
Two hands after the 87 bluff and show I picked up AA off the button. I checked preflop and checked on a board when an ace hit. I called his bet. On the turn I bet out and he raised...I called. On the river I pushed all-in as I had done several times in the hands before. He thought for a minute and finally called, showing bottom pair... I turned over my aces and raked in a huge pot. I busted him the very next hand.
I DO NOT recommend showing your cards...however, I believe that heads-up at the end of a torunament or after a while of sparring in a heads-up match showing your cards has 'advertising' benefit.
