Can White show that he is not in zugzwang? Black faces the difficult choice as to which
way his king should go. In the game he did
not manage to make the right decision. Show
how, with a few precise moves, he could reach
a familiar theoretically drawn position.

Black can win, even though the checking
distance of the white rook is actually long
enough. Do you know the procedure?

B) Carelessness I Loss of
Concentration
'It's a game of 90 minutes', goes the old soccer
adage and in the metaphorical sense this naturally
also applies to a game of chess. Humans
are not machines and it is obvious that towards
the end of an energy-sapping struggle you will
feel tired. It is therefore imperative that in the
final phase of the game you mobilize once again
all your reserves of energy and concentration.
There are innumerable examples in which one
of the players became tired towards the end of a
game. We urge our readers to take care, as tactical
possibilities often arise in apparently harmless
positions. Let us see what happened in the
following game (see diagram on next page).
With his dangerous passed pawn on e3, Black
is clearly winning, since White can no longer
stop the pawn. However, White's last move has
set a fiendish trap.
