10/20 NLH Live Game - KK versus regular limp all in AA guy

[The Dingo]

I play with a guy regularly in 10/20 NLH where there is basically no cap on the buy in. I usually buy for $3-4K and am one of the mid stacks (range $2k - $10k).

One guy loves limpin with AA and then reraising all in for huge pots.

Recently I was in bb, the reraiser was UTG and we were 7 handed with stacks


UTG (limper) $12000 limps for $20
1 $3200 raises to $90
2 fold
CO fold
Button fold
SB fold
BB (ME) $5500 reraise to $440

I reraise to $440 expecting maybe one call or reraise from 1 who is TAG as is UTG.

UTG tanks for 2 minutes and reraises all in, a massive overbet but something he does a lot with huge hands......

1 thinks for a minute and folds.........

I am kind of stuck cause he may know that I know that he does the limp all-in trick with AA but he is cagey and may now use ATC against me cause I have folded big hands to him over many months...........

I lay down my KsKd after about a minute but think he may have pulled one over me even though he shows the Ah and folds other face down.

I folded cause I thought I could grind out a good result with post flop play over the day but what do y'all think
