I don't feel like reading all of the replies quite yet... but I definately think that a flop bet is in order.

With no money in the sidepot, as of yet, there's nothing to fight over. Since the villian here is described as passive, I doubt he raises us often enough to worry about it, then we can take our free card if we want it, or have something to win if we hit.

There's nothing tricky about checking behind and waking up when the flush hits.

Edit: Not to mention, against this donk, we probably have the best hand, and any two cards have at least 6 outs, or are ahead.
