How to Understand Chess Combinations | Chess Video Lecture | Chess Tutorial Course: Beginner to Advanced - Class 6

in chess a combination is a forced
sequence of moves that begins with a
sacrifice
here is a position from a game played by
two students of mine in a class I did
last Thursday and it was blacks turn to
move Black has a queen a rook and a
bishop
White has two rooks a knight in a queen
so white is up material but black to
play can force the win by playing rook
takes B to check now after the rook
takes the pawn check the King absolutely
has to take back there's no other
possible response you can't block this
check the King can't run over here to
see one because the bishop will say
check so he has to take and then after
the King takes the rook the Queen comes
over to b4 and this is checkmate
so black wins the game by sacrificing
material it's really his only way to get
through the white position forced
sacrifice followed by simple win here is
another example of a small combination
in fact this is what's known as a mate
in two why has the Queen the rook the
knight and the extra pawns Black has the
Queen the rook between the rook and the
night but how does white actually win
the game from here the white can make a
small sacrifice
well a big sacrifice the Queen takes the
rook check to the king the King
absolutely has to take the Queen there's
no way to block this check the King
cannot run backwards because of the
other rook and after the King takes the
Queen Black has a rook to h8 checkmate
to the King so white makes a small
sacrifice but then winds up winning the
rook says check the King cannot go here
because he'd be in check from the rook
you can't go here check from the pawn as
well as the rook can't go here because
of the pawn
you can't go here to g6 because of the
night game over combinations can help us
win from positions where we can't see a
way to get an advantage
