[Dangeresque]

I think leading out was a bad idea here. You either want to trap the field on the flop for an extra bet for value, or blast them out with a check raise to add to your marginal outs. Either way, you're not losing very much by missing the bet here. As it stands there wasn't any great consequences. I'm somewhat worried about your implied odds as well, because your draws are for second best hands already. Admittedly, the CO could have simply been making a run at a scare board, but that possibility drops off when he bets into two of you on the river. I think you may well have been drawing to 7 or possibly dead. The reraise here is overvaluing the hand, and committing yourself to marginal calls on the river.
