the action confused me quite a bit. didn't have any idea with which hands he would play preflop this way. i thought he probably had a pocket pair. i had a hard time to fold since i was far ahead against most PP. however i folded anyway because his betting sequence didn't look like a bluff.
good to see that most people think this is a clear fold on the turn.

he had a went to SD value of 13.5% btw!
