"Please publish this game. It was the first time the analysis from your 1996 book The Dynamic Philidor Counter-Gambit, pages 41-42, was tested in a correspondence game. I had Black against Joe Mitchell of Omaha, Nebraska. The first 20 moves are in your book; so the only new attempt is 21.Ke2. This I parried with 21...Qg2+ and offered a draw, which was accepted."
