new thingy, old concept

Ok, I am going to start a 'What would you do?' dealy doo hickey.... not to garner any criticism.. so, your not allowed to call me names, like, dumbshit, or idiot, or weener.. no names.... These will be hands, mostly, that I folded, and then almost immediately regret it... I'm curious as to how those bettre than me, would have also folded, or not... will try to do this once a week.....

Hand #3824706-16 Summary:

No rake is taken for this hand.
ONEIJAX wins 420.

I have no idea what he had...maybe a Jack.. maybe AK... but, after thinking about it, I feel I should have bet on the turn, instead of checking.. I should have bet 1/2 the pot up to the pot... 1/2 as a block bet, or pot size to represent a J. Oh, and yeah, going in with 73s was just a fluke, I don't normally do that.. but, I might start, heh.. with flops like that..
