Edit: (I've just noticed the first post by the creator of this
thread has been removed...It now looks odd...a game was posted
showing a high rated player falling for Legal's mate...It has been removed.
I've no idea why but it has gone.....Hope that makes sense of Yashin's post.)
I'm sure I covered Legal's Mate.
(A mating trick/trap named after the French player
Kermur Sire De Legal who caught a player with this in Paris 1750.)
I can remember mentioning Game 217237
and Game 228160
where the same Black player Carlitos falls for it twice.
I can lay my hands on 33 examples of Legal's One Step.
Thomaz - Zorin RHP 2005
Black has played BxQ white mates in one with Bxf7.
Over 130 with Legal's Two Step.
Eight - Luck RHP 2003
Black has played BxQ. White mates in two with Bxf7+ and Nd5.
Indosmart User 390621
has pulled off the Legal Two Step 7 times including this from 2007
However...He fell for it himself one year later in 2008.
From this I deduce that we only learn from our losses
and learn nothing from our wins.
An instructive miniature this one.
