CO is 22/17 with 5.8% 3bet over 380 hands. Seen him squeeze some out of the blinds, but not so much elsewhere.

Can't see how he's not squeezing UTG+caller with a tighter range than 5.8%, and if I have 380 hands on him then that means:

a. He's a reg (I'm not so long at these games, so he must be around a lot for me to have 380 hands on him already)

b. He has 380 hands on me so knows I'm tight UTG.

So I'm never getting it in here, but does anyone like a 4-bet planning to fold this deep?
