At this point TPTK or aces seem very unlikely, so either im way behind to a set (8 hands, but the 3 jack hands are very unlikely), way ahead of KJ for 2 pair (6 hands) (and the 6 unlikely QJ hands?), or splitting with KQ (4 hands)

Any ace makes the nut.. but I do think I'm slightly ahead of his range so I went with the blocking bet. What's the correct river play here?
