are so hard that the average reader usually doesn't even try to solve
them. Most of the following double dummy problems are much easier.
Good luck.

South to make 5C after West
leads the DA.
Ruff the diamond with the
CA; over to dummy using the C6 and ruff a diamond with
the CK. Continue with a club to dummy 7, ruff a third diamond
with the CQ and play the AK10 of hearts ruffing with dummy's last
trump and ruff a fourth diamond with the CJ leaving your hand with
the C2 and three small spades.
Dummy has Kxx of spades
and a high diamond and East has the C3 and the AQ10 of spades. Can
you see it coming? Toss East in with the three of clubs,
discarding a spade from dummy. East has to play the ace and a spade
and dummy takes the last two tricks with the SK and a small diamond.

When you play yet another
club, discarding a diamond, West must discard a spade. A diamond discard
allows to you cash the ace and run the ten through East; a heart discard
allows you to cross to dummy with a spade and ruff a heart establishing
the jack. East discards a heart.
Cross to dummy with the
SQ, ruff a heart, cash the AK of spades to this three card end

to four trump. East has the J843 and you have the
A976, dummy has the stiff queen. The lead is in
dummy and you lead a club or a heart. East trumps

along with a spade and a club.
West must lead a diamond
which you duck to East's ace. When East leads a
black card you play the DJ. West cannot take a trick

East overtakes the first
diamond which South must duck and returns a club which West wins cheaply.
West exits with a low spade to dummy's king and the HJ is run to West.
If West wins and exits a diamond, South wins and reels off four rounds
of hearts pitching a diamond and a club reducing to the SA9 and the
blank CK. West must hang on to the guarded ten of
spades and must blank his CA. Dummy exits a club to the ace and South
takes the last two tricks with the SA9.
If West ducks the HK, it
leads to the same ending. South cashes the DA and
exits with the ace and a heart. West wins and leads
a spade taken by dummy's jack. When dummy cashes
both hearts it leads to the same ending.

Dummy remains with the C QJ109 for the last four tricks.

South to make 6H against

a diamond.
Play three rounds of trump
ending in your hand and play the DJ discarding a club. East has to
make two discards on the hearts. East cannot afford to
discard a club because you can set up the club suit with just one
ruff in dummy. Therefore, East does best to discard
a spade and a diamond. However on the jack of diamonds,
East must discard again. This time East is squeezed.
If East discards a club, cash the ace-king of clubs, ruff a spade
back to your hand and ruff a club setting up your remaining clubs.
You don't even need dummy's ace of spades! If East
discards a spade on the DJ reducing to KQx, use your club entries
to ruff two spades in your hand setting up dummy's jack of spades
for the 12th trick.

wins the trick, he must lead a diamond reducing your losers to three;
two clubs and one diamond. If East overtakes the second club with
the king to return a diamond, it costs East a club trick to do so
and you still make your contract losing two diamonds but only one
club.

When you play the H9, West
must discard a diamond as you discard a club from dummy. Now the DK
which West must duck. When you play a second diamond, West must win
and lead away from the CJ.
Had you cashed two rounds
of clubs before leading the last heart, you would not make the hand.
You would have to discard a club from dummy leaving the ten bare.
Now West can win the second diamond and exit with the CJ securing
the C9 as the setting trick.
If West reduces to one spade, two diamonds and three clubs. Play the
DK before the last trump which West must duck. Now the last heart
forces West to discard a spade and a diamond exit forces West to win
and lead away from the CJ.

Win the second heart, lead

and exit a diamond to the queen. Next, the CQ from dummy which East
ducks, say. It doesn't matter. You enter your hand with the CA, discard
a heart on the DJ, repeat the spade finesse and ruff dummy's last
heart with the SK before exiting your hand with a club to East's ten.
Everyone remains with two
cards. Dummy has the SA and a club, East a diamond and a heart, you
have the S98 and West, the Q6 of spades. When East leads a red card
you ruff with the eight. If West overtrumps with the queen, you overtrump
with dummy's ace and your S9 takes the tenth trick. If East underruffs,
the SA takes the 10th trick. A smother play.

South to make 6S. The opening
lead is the D2.
The idea is to set up the
hearts to pitch diamonds, but dummy "appears" to be one
entry short. You must win the opening lead in dummy, cross to the
HK and lead the S5. When West produces the S6, play low from dummy!
West remains with hearts and clubs. If a heart is returned it is easy
enough to set up the heart suit with one ruff using the SA as the
reentry. Ditto if a club is returned, ruff in dummy, discarding a
diamond, discard another diamond on the HA, ruff a heart and enter
dummy with the SA to shed your last diamond on an established heart.

You must play the CQ (you

Cash the AK of both major suits, return to your hand with a diamond,

After West preempts in
hearts you wind up in 3NT and West cleverly leads the D7.
The good news is that you have 10 top tricks. The bad news is that
you are playing in a tournament and overtricks can be crucial. Your
job is to make 5NT!
Solution: Win the
DK, underplaying the D8 and cash the SA and the CA stipping West
of black cards, and the DK and overtake the DJ retaining the D3.
Now comes the big play: exit with the D3 forcing West to win the
trick. At this point North has to lead a heart.
