A

idea, the

pawn
in
order
to
help it
promote,
moving
in different
directions
in two
variations.

the apparently
wasted bishop moves
have forced the WP to b7, which
the
WK
needs
to
reach.
P5417 is a
simplified
version of a
study which appeared
in the
October
1995
issue of diagrammes
(That
version is
7sf7Pl16l2K5l6b1l1PsWA
Draw). Few solvers
submit
solutions
to
studies,
and even
fewer submit correct ones
(hence
the
lack
of
comments).
Perhaps
it
is
simply a
case
of
the
studies
being too
difficult,
or
perhaps
the
majority
of solvers
are
not
players.
Would
it
be better to
omit
studies
altogether?
Any thoughts
on the subject are
welcomed.
