NL100: AT makes TP OOP and gets raised on the flop

[AlexB182]

Main Villain here is a NL100 reg, running 15/6/0.65 over 900 hands so far.
I'm running at 16/11 at this table.
Reg might put me on a CB here thinking I might have missed the flop but I'm rally not sure if he/she would raise me on a pure bluff here given his/her AF...
Comments appreciated!
