What Is Légal's Pseudo-Sacrifice? | Chess Video Lecture | Chess Tutorial Course: Beginner to Advanced - Class 6

hi this is coach Jeremy again I'm going
to show you legal pseudo sacrifice which
is quite cute if you haven't seen it
before
efore 'if I've Knight to f3 now the
whole point of this is to show what
happens when black fails to develop and
how severe that can be early in the game
so instead of going knight c6 and
developing a piece black goes d6 we
developed a Bishop to c4 now
black makes this unnecessary move of h6
white develops a third piece and now
white is ahead and development
considerably three pieces to none
because a pawn move is not a developing
move so black makes their first
developing move and it's the most
aggressive move they can possibly make
pinning the knight to the Queen so white
just goes ahead snaps the e pawn and
exposes their Queen to capture the
reason why this is a pseudo sacrifice is
because a piece that's pinned in front
of the Queen is not an absolute pin it
would be an absolute pin where the
knight in front of the King but black
greedily takes the Queen not expecting
Bishop takes f7 check the knight is
cutting off d7 so the King only has one
move and then to black's amazement
Knight to d5
checkmate with the knight cutting off
the escape squares on f6 applying
checkmate and the other night on e5
cutting off the escape square on d7 and
protecting the bishop and there you have
it mate with three minor pieces after
sacrificing the Queen and this is what
can happen if you fail to develop and
how dangerous you can get early in the
game
