How good is your chess calculation?
It is white to move!
Alena, after 5.Rc3, I have a hard time finding a path where black doesn't lose a pawn on the queen side, too, giving white, eventually a passed pawn to go with the one he won on the king side- close to decisive.
Taras2k, what about 1.Rd3 Re6? This might give white some advantage, but it surely looks small to me.
I only see a small advantage for white.
