Really not a fan of trying to iso an UTG limper with A3s from MP with the world to act behind. Perfect situation to limp behind and try and get a multi-way pot with a great hand for that scenario.
I call because the vast majority of live players aren't savvy enough to give off reverse tells
What if I am villain 2 and Hero is an unknown reg?
You mean if you had Ah3h in villain 2's spot? Snapping villain 1s river jam and probs puking everywhere if hero jams. Probs fold though cos I would be flatting 8x too
