I seem to get this to be true only when $\sigma< 1$... and that might sense somewhat.

You were probably too wasteful throwing away the $\Phi$ term.

comment The mathematical odds of winning a hand in poker with two boards
Nevertheless I actually don't think ^ matters much. The losing player has a better chance of keeping the money (so does the winning player).

This would surely also depend on many more things: on how many overcards does the player with a flush draw have? whether the player with the pair is holding one of the outs for the flush? Was the pair a pocket pair? etc. You should give a specific combination of cards, then I am happy to calculate these for you.
