Here is the scenario. Player just sat down at the table. He seems to be donkish, he bitches and whines on chat for about 5 minutes after his set gets beaten by a flush.
He is on the button, I am on the cutoff. I have pocket 10s and it is folded to me. I raise up to 2 dollars. He calls. Flop comes 4s 4d 5d. I bet 4 and he calls. The turns is a 3c. I bet 7 dollars and villain pushes his stack of 29 at me. What should I do?
