I disagree. 1) I'm very well aware of the fact that GM Andersson played
against IM Giardelli and not Deep Fritz. Just look below
the board.
2) Where do I state that black's advantage is enough to win?
I wrote that black is better in the above position.
3) Feel free to test this position any way you like...
