{A really interesting game: a standard Najdorf middlegame with a lot of tricky
tactics between moves 25-35, and a technically challenging opposite coloured B
ending.} 58. Bd4+ $2 {Pushes the attacking King back, which is a good thing,
but it puts the B on a square where it can't get to the only saving diagonal.}
