Pumping one-card non-nut flush draws

[topspin]

Mainly curious about flop (and maybe river). Action would be standard with so many players and the 2nd nut flush draw, except it's a one-carder. Does this slow anyone down? Also, does anyone raise the river when the goods come in? Seemed like a good place to go for overcalls.

I'd raise the river. In .25/50 He's probably just crossing his fingers that you don't have any diamond. It's is the second nuts, after all...
