210 How TO Pl.AY CHESS ENDGAMES
E) Tied and Pinned Pieces
Sometimes the weaker side succeeds in saving
a tricky situation in which one or more of the
hostile pieces is tied down by a strong threat.
The tied pieces are then incapable of developing
any activity and this makes the conversion
of a material advantage impossible.
El) Tied to a Pawn
Often the stronger side is unable to convert his
advantage, since the defender threatens to capture
the last pawn ( or one of the last pawns) and
thus bring about a distribution of forces that is .
stone-cold drawn. The pieces are then tied to
the defence of the pawn and are thus unable to
develop sufficient active power to breach the
enemy defences. The following example is a
beautiful demonstration of what this means:

Black is even willing to sacrifice his own
pawn to tie White up yet further by activating
his king.

11.45
M.Liburkin (end of a study)
Bulletin Match Moscow­Prague, 1946
Despite his great material advantage, Black
is unable to win, since his rook is tied to the defence
of the e6-pawn.

Also in the next case the attacker is paralysed
by being tied to the defence of the last pawn.
Another form of tie occurs when the weaker
side manages to tie down the enemy forces by
particular threats by pieces. In the diagram on
the following page, shutting the king out of the
game is also involved.
