Ya know, I have won a lot of hands with an unsuited 6/2, but only when I was in the blind. We talk about that all the time and the answer is always, "And I'll fold that hand the next time too. While any 2 cards can win, Odds are that pocket aces will beat 6 deuce 90% of the time.
I have a hand that I will almost always call with pre flop. That's a 7/4 I may even call a modest raise if they are suited. It's uncanny how often I will flop straights, trips or 2 pair with it. My usually poker folks have even named the hand "Ernest Borgnine" (Borgnine's PT boat in McHale's Nave was PT 73. Close enough I guess.)
I don't think gambling is a sin. It may be a vice, even an addiction in some people. I don't bet scared money. I don't spend my last dime to try to win back my losses. I see when it's just not my day and I stand up and walk away.
I do play 3 or 4 times per week, but it's part of the business I'm in.
