Remark: 17. Bxf6 is a move suggest by chess program. Why do you suggest that
because I dont see the reason.

Remark: Can you be accurate here? Specifically, what is the "something" that
Diep might have? I am concrete here: I would have put the Rook in h3. Could you
see the idea?

Remark: When you analize a game, you should be more specific. Kotov in his book
called "Thinks like a Grand Master" always pointed this typical mistakes out in
the amateurs comments. Do you see what the white queen is doing here? On fact,
as I have pointed out below: this is the direct mistake in the game and this is
the critical point of the game as Kotov used to say. The rest of the game is not
important because White signed its death here. The Queen Exchange is incorrect
because the Queen is supporting all the queen side. When the queen´s exchange
was done, Hydra had the free way to consolidate his position with the rooks and
the bishop pair.
