Hi

Today I played this nit here:
http://weaktight.com/5810400

It's just ridiculous how he plays, today he slowplayed me successfully for the first time (after 500 hands).

He's 19/9/1.1/1.1 (3bet IP/ooP) AF= 1.8, Fold to 3bet: 14
Cbet 3bet POT: 50%
check-fold OTR 95% (!)

So because he check-folded 95% of all hands and his 3betting of 1%; I put him on AA** on this flop and tried to move him off his hand:

I should have seen his slowplay when he called the turn, I think his holding was:
a) KKQQ
b) AAKK
c) AAQQ
as he's a huge nit.

We have no history where I tried to bluff him, I don't have a clue why he slowplayed there, given that so many straightdraws hit us 2 opponents!

Anyway final question: 
should I fold preflop? This is probably the only opponent where AA28 preflop fold makes sense, as he sometimes shows up with stronger Aces, is capable of folding to a 3bet as a huge nit and we've got a rundown-ish hand who called his 3bet and MUST know that we both could have AA** if capping (in that case I'm 20-25% 3way All in)
