[Drasis]

Folding this preflop makes your life so much easier. If you're seriously playing JJ74 for 3 bets, how do you not raise the turn. You're virtually never going to see a better board for you hand.

So either don't play it or go crazy when the jack hits, and maybe fold to a reraise. Don't put yourself in these positions with mediocre hands.

As is, b/c the river.
