One bad move nullifies forty good ones
One bad move nullifies forty good ones (c) Horowitz
This is one of my own games. I played for Black. Queen's Pawn Game multifaceted. This simple at first glance game opens up new horizons in the theory of chess. It shows visibly competent game in defense. Why White played 11.e4, can not understand, because it is fundamentally wrong. I think, White simply were not prepared for such an eventuality. Mantova is not weak player. We are equal in strength. But I have a lot of experience playing in this debut, and I know, how to play it. I was not entirely sure that the victory will be for me, but after the first ten moves it became clear.
