coldcall - 4bet from SB. What ?

[Yentz]

Cryptologic 500NL 6 max

Table is 5 handed, and SB is a 20/11/2.8 over 2k hands, $ondro$ for those of you that know him. BB is a tag, certainly capable of making squeezes with less than premium hands.

I usually play TAG 20/16/3 or so, but still opening a lot in the button, playing tight oop. I dont remember having done anything at this table that should alter that view of me.

On to the hand :

Folded to me in BTN, I make it $20 with red jacks with $850 behind, SB ($750) coldcalls, BB ($420) raises to $85, I elect to call in position, SB now makes it $245, BB folds.

Wtf? I have never seen him do this before?

Fold. Could just be resqueezing- but i think he doesn't want to play KK/AA 3 ways, and now there's enough money in the pot make a move at it.
