Ethical/Rule question re: showing your cards in live games/tourneys

[Mayhem]

1) I'm quite thick-skinned when posting online, but that doesn't mean I'm not going to give what I get and just sit back and take crap.

2) I can't really debate my 'poker skills' because I'm sure it is a losing proposition, but if there is a way to find my tourney finishes etc. - I'm 'rottmaro' on PokerRoom. Just came in 5th of 143 in Sat night's 30+3 multi. And I probably would have come in higher if I had been able to show my straight to the guy that called my all-in with 2 overs and a flush draw after the turn.

I appreciate what people are trying to say - get your money in with the best hand and hope for the best - there's not much else you can do. But when you are faced with that proposition for large amounts of REAL MONEY - I'd like to do whatever I can to leave nothing to chance.

If you saved up $10K to play in the WSOP Main Event, you were on the bubble and you knew you would win a big pot vs. get busted out if the guy contemplating calling your hand caught a card on the river when you had him beat right then - wouldn't you want to just tell him "buddy - I've got you beat, don't call"? I sure would.
