2/4 Blind on blind whats the min you call with here?

[DrMagic]

400 eff stacks, villain is a good tricky tag, capable of 3 barelling I would say, but I've never seen him do this before. He's playing 22/19/4 or so this session.
I've been quite tight this session, quite unimaginative, might image would be that of a straightforward tag, like 22/17/2ish

Folded to villain in SB, he makes it 12 to play I call

Flop Ah Th 6s

He bets 20, I call

Turn Tc

He bets 46, I call

River 3d

He overbet shoves for 320

So whats the min you call with here? And is there much difference between having say AK or T9 here?
