AK where I 4bet pf and realize I'm pot committed -- 50NL

[Kasane]

My villain is a reasonable TAG player who will 3bet AK-AQs pf and maybe a little more than usual when he thinks you're fos. I do think he's tight and folding most everything to a 4bet.

I think he thinks I'm an aggrotard. I've been raising a lot and shown down a couple of weird ones. I've been b/folding a fair amount, and c/folding from called c-bets.

Thoughts on the 4bet size welcome -- I thought a push would convince him I have exactly what I have, AK and he'd call with a ton of flips. As long as it was push or fold, and I didn't mind pushing here OOP, I felt I'd be more likely to get a fold at this point from repping AA-KK with "call me" 4-bet size. Might be mistake #1.

Once he calls, I think we can seriously discount KK-AA for villain and put him on JJ-AA (leaning heavily towards the bottom) and AK. We don't need villain to fold very often to make a push correct here, do we? We're getting called pretty often though.
