If I think that villain will throw away a hand like AJ here, is this a worthwhile play? Over a couple hundred hands with villain, he's thrown away some TPTK-type hands facing big bets from myself because he views me as "too tight." It doesn't really look like the king helped him on the turn, and with my river bet I'm representing JJ+, AK. Reasonable, or spew?
