I would call any bet including a shove, can't see a smaller bet ($20 blocking bet? meh), so my response is to shove. Trips and Qx will call a shove, obv we're behind to a lot of possible hands.
Note, however, that I'm getting killed in these spots against this villain type. It's never with the flopped fh, it's always a rivered flush or rivered fh.
Since I'm getting killed in these spots (results oriented ftw/fml), any good argument that this is a ch/f or bet/fold would be appreciated (I suspect Deco's in a similar spot) - I'm just not seeing it though.
