The river is a problem for me. Your check will induce a lot of bluffs. But the most obvious draw got there also. So this raises a big problem. What do you do if he bets full pot on the river?

I would probably prefer to bet the river and fold to a raise. Nobody raises there without the flush at $50 NL.
