First hand, button with multiway action can be playing a hand
with a four but more likely hands are a hand with an Ace. I've got almost half my stack out there already. I'm not going any where with this. Call. If you push he might fold a hand with a smaller Ace. He might interpret your call
as a sign of weakness and continue betting the turn and river. You're either way ahead or way behind.
