How Would You Play This Hand?

[West]

Well if a spade falls, or the board pairs, I can check behind. Even if all two pair and set hands are going to fold to any bet on the river, I think the fact that the BB is more likely to have a smaller flush than the nut flush, combined with the low likelihood of him checking the nut flush on the river, means I've still got a good value betting opportunity. If opponent does push in with a check raise, you can always reevaluate then.
