I think you're ahead a lot here, but I guess this is what they mean by 'merging your ranges' and don't mind it horribly. He's very rarely full here, and if in the past you've shown a propensity to value-bet thin (i.e. KTxx here) this bet becomes a lot more believable. He ought to be folding any jack here that's not full, so I guess it just comes down to how often you think he's full here: very rarely, so it's a good bluff.
