Is is folding KKK standard here?

[Biggenx]

Ok, so the hand went something like this, ep raised with who knows what, and the guy directly to my right (CO) reraised. I have no read on him since it's my first time playing at PokerStars.

This is a $25 PLO table, so i have trouble respecting anyone's raises.

So this guy to my right is obviously trying to represent pocket A's. I have KK double suited with J/ rag.

Flop come K blank A rainbow, he bet the pot, and i think that call was ok, then a J came on the turn, might have given the board two suits, also possible straight, and this guy all but goes all in. I think i should have folded. Now, does a fold here completely rely on a read, or is it standard?

oh, and i had 2x the buy in verse his $5 less than buy in.
