Now the
BlacR
Rin~.
Kazir.
has made himself
invisible. But theWhite
Rin~
.
Haroun. has such
powers of
reasonin~
that he can
mate Kazir in one move as
unerrin~ly
as
if
he
were visible. What
is
the move ?
( for solution. see
pa~e
124 )
amazin~
is
Haroun Al Rashid, and the White bishop
is
his
grand vizier Archie.
Together
or singly they
outwit the
Black king Kazir's
attempt at
invisibility, and the
Black queen Medea's disguise. In addition, using the
deductive logic
that
is
the hallmark of these exercises
in "retrograde analysis," Haroun and Archie uncover
pawns who have robbed the royal treasury, escaped to
the eighth rank and promoted; they track down lazy ·
knights who have refused to move more than once or
twice; bring to light castles
that
have been buried; and
encounter numerous phantoms, genii, magicians, phi-
losophers, hermits, and beings of all sorts.
There
is
an introduction
that
shows anyone who
knows the basic chess moves how to do these problems
in retrograde analysis- and,
at
the end of the book, a
bonus of twelve conventional chess problems.
A treasury of royal delight for anyone who likes chess
problems- or intellectual puzzles of any kind.
