Avg is probably around 30-35k at this point. Previous hand UTG+1 limped and villain shoved for 42k in the CO, and everyone folded. Only hand villain played since he got moved to the table about an orbit earlier.

3-bet and call a push? Call? 3-bet and fold to a push (not an option imo because that's pretty bad).

Thoughts?
