Buzz, you're forgetting that you get your $25 bet back twice as often in the case where you're drawing to a low as compared to the case where you're drawing to a scoop. Have to include that to get the odds right; when you do, you'll see that the "extra dollar" has been there all along.

TG, the two hands are equivalent equity-wise *and* risk-wise, 2dimes isn't pulling any fast ones.
