15. Bc7
You might ignore me since i am just found this thread. I usually play cheese so slow that my opponents gets sleepy. This 1 month game would be perfect for me.

I also play Cheese :-p
I have also looked at that move but it doesn't do that much. It would be better if the bishop could go to b6 after that but his knight defending that field.
I would say 15 Bc7.
We drive away the Rook and we can always bring our bishop back (if it is attacked).
