{ There are different reasons a game grabs one's eye.  It might be especially well-played.  Or, it might be especially instructive as regards an opening variation, for example; a so-called "model game".  This game is both.  By the way, the reader might get the impression that I am picking on Whitely's annotations to the game, which I have cited at several points, because I think they are poor.  This is not the case, rather the reason they got cited so much is because they were extremely relevant and a time saving starting point for me to attempt to dig deeper. } 1. e4 e6 2. d4 d5 3.
