I don't like the call turn check call river line becuase the pot will be too big. There will be over 2k in the pot, so check calling the river can be disastrous.

I like a push instead. Even with the 4k stack in there, a push is barely bigger than a pot sized raise. I can't see anyone having a straight, and I can't see anyone calling UTG's raise on the turn with a higher set.

UTG can have anything, and he's shortstacked, so we're not really worried about him. I'd say one of the other two players hit the ace (most likely 2 pair, possibly 1 pair), and the other has a 6. Combined, they have lots of outs, so calling and check calling seems much worse than shoving it in there.
