Big pot, is this too crazy?

[tl65\]

Wild party 30/60 game, full table, UTG+1 is 53/25, UTG+2 is 71/23, CO is a little tight(16/10) but a good player.

UTG+1 raises, UTG+2 calls, I 3bet with A [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/club.gif[/img], CO cold capps, everyone calls.

flop comes: 693r with one club

checked around to CO who bets, UTG+2 calls, I raise.

I had been playing fairly tight up to this point and the pot is huge, so i'm thinking if this could buy me any bluff outs it's worth it.
