You need to give your program hours to search in order to test this position(Deep Fritz needed some hours only to find Nd5) I have also 2 questions about this game: 1)Is 27.Ndxb5 a correct move? I believe that it was a mistake and black has better chances to win. 2)What is your opinion about the final position? I believe that black is better and I was happy when my opponent accepted my draw offer when my opponent believe that it is a draw.
