Gotta fold this right?

[dibbs]

50$ Party PLO
Enemy is table laggo maniac. We both start hand about 200 bbs. He could have nothing or any wacky combination of cards. You have JJTQss in ep.

Flop comes J 2 4 two spades. you bet pot he calls.

Turn is a 2 you pot it he calls.

River is a 2. I check he bets pot which is at 50bbs

Easy fold given description of player right? What if he was generally tight? anyone bet the river?
