The only hand to fear is AA. If his read was a PP then you are in a coinflip situation with overs, marginal loser against KK and a big dog against only AA. With Dead money in the pot, as stated before, call is the only response.

Here's something worth noting that I posted in this thread about AK.

According to Sklansky,

AK is the favorite against any non-pair hand, a slight dog against all pairs through QQ, a moderate dog against KK and a huge dog against only AA. The fact that you hold one Ace cuts the odds that your opponent has AA in half.
Also, AK doesn't play well after the flop OOP with deep stacks, especially in multiway pots. Blah, balh, blah.... because AK is unlikely to be in trouble preflop, but often has limited value after the flop, it's often best by far to make a big preflop reraise with it.
