NL100 - AKs, flush draw, reraised pot, easy turn shove?

[RyanCMU]

Villain in this hand is a 20/7/3 multi tabling regular, who I think is pretty awful... Unsure how he views me, I have been playing pretty tight at this table cause Ive been pretty card dead. However, I'm not sure if villain has PT or keeps notes on our previous play, we have tangled a lot in the past, usually with me showing down pretty strong hands and winning. No interesting history or relevant hands I can think off.

Anyways, my thinking on the turn is that if I fire and get called its not the end of the world, as I likely have mucho outs. And also, he may fold TT-QQ?

This might even be standard? So who fires turn here and who takes the free card? Is the turn shove standard, and Yea I think I should have sized my flop bet better.
