PART 1 • What you can expect to see after a game analysis Here's an example, showing Houdini 2's analysis of a game in Chess King: Houdini has provided evaluations of every move, suggested improvements at places where each player could have played something better, and even identified the point at which one player deviated from known opening theory (marked with an “N”, for “novelty”) and inserted examples of known opening play taken from Chess King's huge database of games. When reviewing the analysis of this game, I realize that I could devote pages of this book to pointing out various aspects of this game and its analysis – both players made some significant mistakes. But here are just a few highlights which we can consider. White's opening choice: White left “book” when he played 11.g4. Houdini provides two alternative moves which have been previously played in other games. But since White's choice gave Black an advantage of 0.18 pawns, while the suggested move would have kept the game essentially even (0.04 advantage to White), this isn't a major red flag for White. If the opening is one the player sees regularly, he might want to play over the suggested variation, and keep 11.a3 in the back of his mind for future reference. White errs almost immediately thereafter: On his very next move (12.Nce2), White makes a notable mistake. Black has a slight advantage after 12.Bxf6 etc., but White's maneuvering idea changes the evaluation by about a third of a pawn, which is enough for him (and us!) to take notice of. 99 chessking.com
