Bizarre river raise

[tessarji]

I would 3-bet.

I feel his most likely hand is a high pocket pair or A9 that is raising the river for value, banking that he's usually ahead and that on this scattered board you won't have a 3-betting hand ever. He doesn't put you on a flush because you 3-bet preflop which contraindicates suited cards in his mind.

I think he will usually pay you off with several hands less than a flush.

I'd call a four-bet because he is a spaz.

You don't think he would ahve raises TPTK or the like earlier in this hand against 2 opponents on a draw heavy board? And he would have to be an absolute moron to pay off a river 3-bet with just one pair.

3-town express

Given the description he could have a variety of hands like 46s, A3s, or a lower flush. I think you would be missing alot of value not 3-betting. If he 4-bets then i think you have to call.
