Anyone defending Prawney's line is absurd, check calling all in on the turn is horrid despite the implied outs, and sad to see so many people that agree it's an ok-play. Has nothing to do with records or winning history or anything else, but, it's a really poorly played hand. The flop c-bet isn't terrible by the OP although the board is rather wet, most players can only call with any type of a straight draw, but when the King drops on the turn and he fires all in, it's a terrible stack off. He's pretty much banking on hitting a flush or some straight combo as he has to figure he's probably up against a pair, if not a made hand already, as he could easily have JT in this spot, and is drawing only to a chop... EV wise, long-term, OP is right, AS PLAYED ----> bad play. A more profitable solution would be to bet/call a raise, or even lead the flop. Stacking off is so LOL.
