[Retros] Die Schwalbe Heft 228, december 2007 again

[Bernd Gräfrath]

Hello again,

in addition to my previous e-mail, I want to add some more precise information:

Joost did not find a cook in my problem, because the uncapture of a Bg5 is a correct solution,
while the uncapture of a Qg5 is only a try and does not solve because of a forward defense.

Furthermore, there is a second intended solution with a different uncapture...

Best wishes,

Bernd
