No, that your taking hands with good calling EV and making them bluffs. A hand like K9s has some TP/draw potential when villain continues, some flops will also allow you to barrel. Think of it this way. You 3bet IP and MP calls Flop comes down A95r one heart. You cbet and the villain calls. you have second pair, a backdoor FD and initiative. There are so many cards that will help you fire another barrel on an A high flop when you hve 3 bet. Your obviously second barreling any A that you 3 bet, and now any heart, K or 9 (14 outs) gives you tons of equity vs some random 88-TT, Ax type hand. If you three bet 44 here, your drawing to 2 outs with someone calling a 3bet and cbet OOP. DO you really want to fire again vs someone who doesn't believe you since your 3betting so often.
