This is quite true -- the problem of getting programs to select the right kinds
of lines from their opening books continues to cause trouble. Here, I don't
think Rebel reacted so badly, despite disliking its own book line, and Junior's
17.Qf4 left the position rather closed, making it difficult to exploit White's
two bishops.
