Most of the great games qualify for analysis by the rules of post mortem
parfait, and as a guess fewer than 10% other recorded games, not having
recognizable ''brilliancy.'' No opening theory and everything is given
before such ''brilliancy'' usually being or leading to exchange
sacrifice that works. In 1935 Euwe-Alekhine,
http://chessgames.com/perl/chessgame?gid=1013180, that point is reached
when Euwe-White lets stand capture of Bishop Move 21...Bxc3. Black stays
that one piece up until Move 33 exd7...
Moves 22 to 47, the end 1-0, are about the longest stretch so far any score to ask
where the losing side went wrong. There may or may not have been rote memorization
before Move 22, but that half of this game is off-limits. Where does Black
go wrong this time?
