Dump the overpair?

[private joker]

6-handed game due to walkers.

Folded to me in the CO and I raise JJ. The SB (mostly unknown guy, but doesn't seem too LAGgy or too weak or anything extreme) 3-bets. Back to me and I 4-bet, he 5-bets, I call.

Flop is 743 and he bets.

What's the plan for the rest of the hand? Peel and fold the turn? Call down? Dump it now? Raise/fold?

I also feel like my hand posts are getting dumber. Apologies if you are reading them.
