KQs, this is just awful PF

[MRBAA]

If you hit this hand, you will like it. Your thinking is really too scared. Any king or queen, you're probably winning. If he has AK, AQ, KK, QQ or AA then congratulations. Given his position and the fact he at least seems a bit aggressive, he could just as well have 66-JJ, AJ-A9, KJ-KT, QJs or less.

And, if you are fortunate enough to get a couple of spades you can take him down even if he does have a big hand.
