I think the point you may be missing is that you're putting a raise in against a hand you're behind, with only 1 card to come to beat him. There's no value in raising when behind, in a heads up situation, where he won't be folding to your raise. You have no 19 outer here, that's a gross over estimation. If you're willing to attribute a range of hands, then figure that sometimes he's got the flush, sometimes he's got a Q (so your K's are not outs),etc... I'm willing to accept 12ish outs. 1 in 4. Certainly not a scenario where we're trying to pump the draw.
