$1700 eff. My image is a nittyish TAG grinder. Villain....... perhaps not surprisingly is the same. I've seen him do a big move like a river check-raise bluff but only once in a blue moon. I've seen him triple barrel a dry paired board. So he's capable of pulling something out of a hat but does so very rarely. I've 3-bet him a lot earlier in the day, mostly his button opens and he generally folded pre or after a cbet. There is a possibility he's somewhat sick of it but I really discount it. He flatted my 3bets like 1/3 of the time and folded the rest. Not sure what that means.. in terms of his flatting range.. honestly still have no idea what it is. This guy doesn't go to showdown very often and neither do I.

Anyhow, I have A♦ A♥ in BB. V opens to $30 in CO. He does open up in LP like any reg TAG. Button LAG called. I 3-bet to $120 and both called.

Flop: Q♠ 8♠ 4♠ Pot 365 I cbet 250, V calls, LAG folds.
Turn: 7♥ Pot 865. I bet 450, V shoves.

What do you think of my line and what do we do now?
