54s becomes low straight in raised pot. River action?

[DJ Sensei]

Pokerroom NL $50

Reads: limited, although Villain B's 3x LP raise doesnt mean much strength (i.e., called preflop because of position on preflop reraiser and certainty that it wouldn't be 3-bet)

Villain A checks, Hero ?

(Hero and Villain A have about $30 behind, Villain B has around $40.)

A few questions about the hand, especially on the river.

1) What hand ranges do you put both villains on?
2) What is the best river action for hero: bet (how much) or check?

I think this depends on whether you respect either of the other players as decent or not. If they're typical morons, you're probably good here most of the time. If you're unsure, you can just call the river because of Villain B behind you. You weren't reraised on the turn, so it doesn't look like anyone has a set unless both of your opponents are very passive or always slow-play.

So if your opponents are aggressive and not good players, I like pushing the river because you get called by a lot more worse hands (pot is already big enough) than better ones. If they might be good or they're passive/slowplayers, use your instincts based on your reads and decide whether to check or bet.
