One of the more frustrating things I found when learning chess was that sometimes annotators would pass over a move without looking at obvious alternatives. Well, obvious to me at least. Often I would be left scratching my head after seeing a player not swap queens (for example) and then get mated, by the enemy queen, 6 moves later, with the annotator failing to mention QxQ as an alternative.
I like to be shown things, especially if it isn't obvious what would have happened next. Now one example of this has always stuck in my mind ever since I started playing chess seriously. One of my favourite opening books is "The Italian Game" by Harding and Botterill. The chapter on the Wilkes-Barre has long since been covered in the stains of my grubby thumb prints, but there was one line (and lack of analysis) that always irritated me. So finally I put the game into Fritz to try and discover what had been left unsaid by the authors. (The comments are mine btw)

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5 5.Nxf7 Bxf2+ 6.Kxf2 Nxe4+ 7.Ke3 While this move looks suicidal, it is considered by some as the best chance of refuting the Traxler. 7...Qh4 8.Qf3 Now this move 'looks' sensible. 8...Nf6!! (D)
The !! were given by Harding and Botterill followed by 0-1. Annoyingly there was no explanation for this assement, and in pre-computer days I found it very hard to find a clear cut win for Black. 9.Ke2 As this just loses quickly why not grab the rook instead.
