40 Rc4 was certainly not a ?? move since it ended the game. At worst, it deserves a ?! since it doesn't win the pinned rook.

This was a really good game for me, with solid play by both of us. White had a space advantage on the king side. But I (black) was able to get solid counter play on the queen side.
Slowly I build up an advantage on the queen side. I miss a few opportunities, but fortunately so does my opponent. And it a particularly ironic way to end a well played game, the my move that forces white to resign was a blunder.
Comments always welcome.
BTW, does anyone know if there is a way to edit the inserted game after insertion and posting? I always notice something silly like confusing black and white in my annotations after I post them. (see if you can find it in this game)
