Double barreling from OOP in a 3bet pot

[STARSCREAM.]

<font color="purple"> Villian in this hand was a 21/17/4 TAG with an attn to steal of about 30. He has been opening a lot of his buttons, this is the second time that I had 3bet him, the first he folded preflop. I was running at about 18/16/6 at the time. </font>
