CO Hero ???

I ended up shoving raising to 330

In retrospect, have a few questions/comments
1. Not sure I should have CBET into multiway. I was feeling like I had a good double barrel setup with 14 outs to improve, but check calling the probable BTN villain bet could have been better.
2. Looking back I think the raise from the villain was very strong and I probably had small fold equity with my raise.
