There was an earlier game in the Noteboom somebody -- perhaps you -- posted
here, with Rebel 10.0 as white vs. Chess Tiger.  The opening was also a
Noteboom, and the verdict of the poster of the game was that Chess Tiger simply
fell into a bad opening line.  I looked at the game, and it was straight out of
"Play the Noteboom", by Mark van der Werf and Teun van der Vorm.  The game
followed Maggeramov - Sherbakov, Moscow 1992 all the way to move 32.  From the
book: "Black has sufficient compensation for the exchange.  The light squares on
White's kingside are terribly weak.  The first threat is 32...Bh3+ and wins."
All the same, Rebel got in f4 and went on to win very shortly thereafter.  I was
going to take a harder look at the line, because if White is really winning
there then Black needs to deviate somewhere earlier... but I've been busy, and
haven't gotten around to it yet.
