TO
COVER OR
NOT TO
COVER
By:
Eddie

When an
honor is
lead
from dummy,
second
hand
generally
covers an
honor with
an honor
in the
hopes of
promoting
a lower
honor for
either
himself or
partner.
You can't
see
declarer's
holding,
so you
have to
hope
that you
are
promoting
something
for
partner or
yourself.
If
declarer
leads an
honor, you
can see
the dummy
and decide
whether
there is
any
possible
chance for
promotion:

SOUTH

South
leads the
S
J. Should
you
cover? Of
course
not! You
can see
all the
remaining
honors,
including
the
S9,
in
dummy so
you cannot
possibly
promote
anything
for your
partner.
(And you
are aware
from your
own
holding
that you
cannot
possibly
promote
anything
for
yourself.)

Again,
South
leads the
SJ.
Should you
cover?
This time
you
should.
If you
cover and
partner
has the
S10,
it will
become a
third-round
winner.
If
declarer
has the
S10,
you cannot
get a
trick
whether
you cover
or not.

Q
South
leads the
SQ.
Do you
cover?
You
should.
If you
cover, you
will take
a
fourth-round
trick in
the suit
with
your
S9.
If you
don't and
declarer
has three
spades,
you won't
take any
tricks.
Study the
entire
diagram:

WEST

SOUTH

Q 6 5
If
you duck
the
SQ,
it will
take the
trick,
with dummy
playing
the
S2.
South will
continue
with a low
card and
the
best you
can do is
play low;
the
S10
will be
finessed.
South, if
he can,
will then
come back
to his
hand in a
different
suit
and lead
the
remaining
low card,
finessing
dummy's
SJ,
and you
will not
take a
single
spade
trick.
If
the dummy
did not
hold the
S2,
but simply
S
A-J-10,
then it
would have
been
correct
not
to cover.
When there
are four
cards in
dummy, the
nine is
often a
vital
card.
Now try
this
one:

South
leads the

Do you
cover?
Your
answer is
yes. You
should
hope that
your
partner
has the
S9
with
three
