what yo uare doing is basically merging your range by checking the turn and jamming the river. problem is, since he checked every street and is OOP, an 8 is in his range. this is why its a terrible spot to do this. you should just bet the turn since it looks so obvious that you have a king or a QQ JJ type hand when u check it (but why would u have QQ/JJ if u checked the flop, right?) so only hand u can have is one holding a K. dcal is a nit and i wouldnt assume him to be a strong player, which is why i wouldnt put this play on him, hes not thinking on that deep of a level, im not even quite sure u were thinking on that level. i'd expect him to have u beat here like 95% of the time.

bet turn get all in.
