I was wondering whether I actually played this correct. I have little information about my opponent but when he checks the flop it seems to me like he does not have very much. I dont think betting the turn and then giving up makes a lot of sense as he will likely call once with AK if he has it. I would assume AK is a fairly large part of his range for checking here (although I may be wrong). So I plan to go bet turn and ship river, which worked in this instance. Is it the right play though given what we know (or actually dont know) of our opponent?
