Kibitzer's Corner
Feb-15-05  Knight13: Pretty good position for a useful White bishop.
Jul-31-13  GumboGambit: Stakes were high here. Rumor has it if Black lost this game, the 1. e6 Queens Pawn defense would have had to be referred to as the Harrwitz Defense.
Oct-07-17  Saniyat24: Very interesting game...earlier it was a two centralized Knight from White against two bishops from Black...thought 16...Bd8 was was a good move providing Black with attacking options...the Queen exchange certainly favored Black...Black had a formidable central position in the middle in the middle game, and whenever White attacked, Black had a very good counter-attacking reply...the h pawn push from Black ensured a win for Horwitz...
