It has been said by GM Rohde and others that Rebel 10.5 was lost by move 20. I
have been looking at the position after move 25, and I am still unable to see
the clear cut win for GM Rohde's. Can someone show the winning line after the
move 26 Bg2 .. . With the help of others and some computer programs the winning
method still elludes me.
Here is an example of what Hiarcs7 thinks of the position.
