In the Polish Immortal by Glucksberg-Najdorf 0-1,
http://www.chessgames.com/perl/chessgame?gid=1100774, White has to contend
with Black Knight and Queen after the Bishop pawn grab called a brilliancy.
Upon the second half of this ''brilliancy,'' 10 ...N-g4, the response
''11 f4...'' is in fact where White goes wrong. That Pawn move neither
gives King outlet square nor deals with congestion. It just protects the
White Knight.
Instead, correction 11 N-h3 pulls the threatened Knight out of harm's way.
Then Black has no good move for Bishop or Horse. With revised 11 N-h3,
Black Queen is not going to dislodge that Knight from the protecting side
file. Black's attack is essentially gone, and what he has now is a weak King side,
facing all three slant pieces of White threatening to bear in.
