this is david from chess NYC here's the
king the king is a very simple but
important piece he moves one square in
any direction however the king because
he's the most important piece always has
to stay safe so if let's say black has a
rook here on h4 the King cannot move to
any square in line with the rook because
then he would be in danger of the rook
capturing the king this is called moving
in to check if a piece attacks the King
he's in check and has to get out of
check the king is not allowed to
voluntarily move in to check if for
instance black had a rook here and a
queen here this rook on b1 confines the
white king he cannot move out here
because he'd be under attack from the
rook and so let's say he makes one one
of his rules he could go either down one
square or up one square then black could
bring the Queen over here to a2
checkmating the white king the queen is
attacking the King check the King can't
go more than one square at a time so we
can't go four squares and capture the
Queen there's nobody that can block this
attack if let's say white had a rook you
could bring the rook over to block the
Queen's attack on the King but he has no
look if he tries running out here to the
B file who'll be under attack from this
rook so we can't go out here
game over checkmate most important thing
in chests keep your King safe
