TPTK vs. the donkey

[spino1i]

Villain is a major donkey in this hand, loves to push all-in preflop. He also is exceedingly liberal and loose. Major calling station. My play good?

Yow! I don't like min/donk bets like that. Good read, though.
I thought he might have an A and is trying to price a gutshot? Either that or A4/55.
