Is check/calling the turn an option? A nice scenario would be someone picked up a flush draw on the turn and hits on the river, but if they did and don't hit on the river, I don't make much off this hand unless someone has (and bets) their jack. Then again, I guess I do'nt make much off this hand unless someone has a jack or T9 anyway.

So I probably should have bet more on the turn?

Turn bet is weak sauce. River c/f is fine.

Raise the flop and make a bigger bet on the turn. SB leading out against four callers means he likes his hand, and the only way you're taking a stack here is by building the pot early. As played, pot the turn. And getting over 3:1 I call the river, he could have the straight or be bluffing because you showed weakness.
