features one of the sharpest positions in current opening theory. The
defender faces a problem, since he cannot match the extreme mobility of the
white pieces. } 6… Nbd7 7. Qe2 { This is a very fresh direction of the
theoretical discussion. In the reaction to the modern 6…Nbd7 White is
avoiding the main move 7.f4, but tries for the immediate castling instead.

benefit from the fact, that at this moment he has an advantage in piece
