Villain is a white male in his mid 50s; seems like a typical tight middle-aged player. He hasn't gotten involved in many big pots. His biggest win came when he got a gift-wrapped pot from a fish who recently came to the table. Villain raised a 9-high turn, and the fish decided to turn over his hand (A9) while deciding what to do. He finally called. Then the fish checked the river and called off the rest of his stack (<$100) when Villain bet again. Villain had KK.
