what would you guys have done on the turn though?

see, i'd been quite aggressive, not massively, but just leading a lot. So i thought he was defending the cbet.

I sort of had him on AK, so when the king came down i shoved, pretty much based on the general reads for 5nl players. I really wanted to cut out the nasty spots to just grind up nice and steady, and i was. Just watched a vid by spenda and suddenly my game improved a lot, then had this bitch of a situation.

so, if you had him on a cbet defend and called, what would you do on the turn? bet-fold?
