Trouble with AK

[GotChips]

I have been having some trouble when AK does not hit..
MP2 is a LAG that will cold call with well lets say not much..When it is heads up, I have had the tendancy to bet out when I do not hit..Any suggestions with AK when it misses the flop would be appreciated..

If MP2 is a LAG, he will call you down with any pair here. Either check-call or check-fold this river...I would lean toward the latter without a read.

I think check call would be the best bet..Would you fire on the turn?
