Weird river decision with 43s

[Ray Of Light]

Without a read, I would fold.

Although, I have to say, the MP2 having a river AF of 2.1 can mean that he tends to play marginal hands too aggressively on the river. So if you know that there is a good chance that he will fold for one more bet if raised, I would raise (shutting out the MP1, who bet on the turn).

The raise is because your pair of threes might be good enough to beat one possibly bluffing opponent, but faced with two opponents, (one of whom would be overcalling behind you), your hand will usually find itself beat.

So depending on your read, either raise or fold. I would not call the river with this hand, in this situation.
