I hate two small pair

I agree that the 5th street bet isn't close, it's mandatory.

But I wonder about the fold on 6th. It really depends on what you figure seat two has. If you assume no one can make a low you're barely getting the right odds to see the river. If you think seat two has a made low (and the only starting hand I see him doing that with is (5h6h)Th if he's a reasonable player) then folding is right. Even if you figure one or both have a shot at a low you're right to fold.
