Hi Omaha Queen - Assuming Villain has the Broadway (ace high straight) and a re-draw to a spade flush, here's the math:
$82*10/44+$41*3/44-$26*31/44 =
+$18.64+$2.80-$18.32 = +$3.12

The total is positive, meaning you have a positive e.v. Another way of putting it is you have favorable odds to draw.

Call.

Assuming Villain does have the Broadway, you'll lose more often than you'll win or tie, and by a 31 to 13 margin. But when you win or tie, you'll more than make up the difference.

It's close, but call.

(If he doesn't have the Broadway, the odds are even more in your favor)
