I am tempted to check-raise because of the small bet of villain 1. But calling is clearly the better play because you are playing against two opponents and there is a decent chance someone has a better high hand (trips with better kicker or even a full house) than you which he will not lay down to a check-raise.

BTW, facing a full pot bet a on the flop from a decent player I would strongly consider a fold.

Calling the turn is fine because you picked up the nut low draw.

Folding the river is fine.
