This hand is from a videogame but I think it's an interesting spot:
UTG raises, 3 coldcallers, SB coldcalls, I have 8
5
in the BB and I call.
6 players, 12sb, Flop comes 6
7
J
SB bets, Hero ???
With 66, 77, JJ, QJ, KJ and AJ I raise here 100% to try to charge draws. I smashed that board every way possible except actually making a hand. If the pot were smaller, i.e. if it'd been limped around preflop, calling to build the pot would be a no-brainer. Even with the pot already pretty big, I have to consider a raise to maximize our chance to win it. A 9 sets up a redraw for anyone with an 8 or 10. A heart makes a flush for us but could set up a redraw for anyone with a lone heart bigger than our 8. Any pair could pick up two pair on the turn. Any pocket pair could pick up a set.
I'm honestly not sure, but I'm leaning toward raise.
