Here either of the one-card menaces may be transferred

to the Southhand without requiring the other to be increased

inlength.

The presence of the split three-card menace makes both

situationsshown in the last two diagrams automatic. The

squeeze isequally effective if the West and East hands are

interchanged.

In the following hand South is declarer at a contract of

sixno-trumps.

West leads the seven of spades, dummy plays low, East\'s

queenwinning.The return is a club.

It seems that the king of spades is in the East hand.

A simple squeeze against East in spades and hearts is

not possible,because the two menaces both lie in front of

East.Therefore the heart winners can be cashed. On the

third roundof hearts West discards a spade, showing that

the heartguard is in the East hand.

If East has the only stoppers in diamonds (queen-knave-

small or atleast five cards), the diamond suit in the

North-Southhands can be used as a split three-card menace

against East,and a simple squeeze against East in hearts

and diamonds,or in spades and diamonds, is effective. In

this case atriple squeeze against East (in spades, hearts

and diamonds)must also be effective. The end positionis

On the lead of the knave of clubs North discards the

three ofdiamonds and East is squeezed in three suits. The

situaion isthe same as in Diagram (38).

Note that if East guards the hearts but West guards the

spades, andthe diamonds are guarded by both opponents, a

doublesqueeze works. The end position willbe as follows:

This is the double squeeze situation in Diagram (16).

Before concluding this section let us once againconsider

the situationin Diagram (33). It is a positionaltriple

squeezeagainst West. But if clubs aretrumps the South

hand isprovided with a ruffing entry and the squeeze becomes

automatic andoperates against either opponent:

On the lead of the ace of clubs North lets go the three

ofspades. IfEast discards a spade, the ace of spades is

cashed and ared king is led and ruffed. South makesthe

last trickwith the knave of spades.

4.2 Asqueeze that operates at Trick 1

A squeeze often begins at the eleventh, tenth, or ninth

trick of adeal when there are three, four, or five cards

remaining.In the extreme case an opponent can be squeezed

at the veryfirst trick as in the following hand played by

South in acontract of seven no-trumps.

West leads the queen of spades. North-South havetwelve

winners ontop. Eastis void in spades and has to make a

discard.In fact, he is squeezed in three suits at Trick 1.

South gainsan extra trick in the suit in which East chooses

todiscard.

If the opening lead is not a spade, the declarer can

cash theaces, kings and queens of hearts, diamonds and

clubs toarrive at the following ending:#

On the lead of the ace of spades East is squeezed in

threesuits.

The entry conditions in this triple squeeze are very

queer.There is no entry in the suit of any of the three

singlemenaces.Either the ace of spades or the king of

spades can beused as the squeeze-card. If Eastdiscards

the knave ofdiamonds or the knave of clubs, South makes an

extra trickwith the seven of diamonds or the four of clubs;

if Eastdiscards a heart, North wins two heart tricks. All

the entriesin this four-card triple squeeze situation are

provided inthe free suit.

The situation is automatic. West will be squeezedif he

holds East\'scards.

West leads the king of clubs, dummy\'s ace winning. Dummy

leads a clubwhich South ruffs. South wins the ace andqueen

of diamonds,West discards a heart and a spade. At Trick 5

South leadsthe king of hearts, which wins. Southcontinues

with thequeen of hearts, West\'s ace winning. At Trick 7

West leadsthe nine of hearts, dummy ruffs with the king of

diamonds, andEast discards a club. A club is ledfrom

dummy, Southruffing with the three of diamonds. South then

wins theninth and tenth tricks with the ace and king of

spades.The situation at Trick 11 is very interesting:

West has three singletons in three suits and all the

singletonsare master cards. South\'s eight ofspades

threatensWest\'s queen of spades, the five of hearts

threatensWest\'s eight of hearts, and North\'s eight of clubs

threatensWest\'s queen of clubs. Now the knave ofdiamonds

is led,drawing East\'s ten of trumps and squeezing West in

three suits.If Westdiscards the spade or the heart,

South\'s eightof spades or five of hearts becomes a winner.

If Westdiscards the club, the North hand is entered with

the lasttrump and the eight of clubs is made.

This triple squeeze of West in three singletons is one

of the raresituations in the squeeze endings.

The squeeze is automatic. If the West and Easthands

areinterchanged, East will be squeezed in three singletons.

4.4 Doubletriple squeezes

Occasinally, at the time the squeeze-card is led, both

opponents aresqueezed simultaneously in all three suits.

When this isthe case the squeeze is called a `double triple

squeeze\'.This kind of squeeze depends on the existence of

an ordinarydouble menace and two pick-up double menaces

described inSection 1.2.

The following are four different situations of double

triplesqueeze.#

In each of these situations the ace of clubs is the

squeeze-cardand tricks will be lost after the squeeze. When

the ace ofclubs is led, North discards the two of diamonds

in each case,and the opponents are squeezed simultaneously.

In Diagram (43), for example, South can win two tricks

out of fivecards. IfWest throws the three of hearts on the

lead of theace of clubs, North\'s ace of hearts drops the

king, andSouth\'s queen becomes a winner. If West throwsthe

knave ofdiamonds, the three of diamonds is led. North\'s

king loses toEast\'s ace and the ten is established. If

West discardsthe ace of spades, East is squeezed. He cannot

discard theking of spades. If he throws the fourof hearts,

the queen ofhearts is led. West must cover, theace wins

and South\'sten becomes top in the suit. If he throwsthe

four ofdiamonds, the three of diamonds is led. Northplays

the ten andEast has to win with the ace. North\'s kingis

nowestablished.

Hence, whatever the opponents might discard, an

additionaltrick can always be set up for North and South.

Similarly, in Diagrams (44), (45) or (46) the opponents

cannot bothdiscard in spades on the lead of the ace of

clubs, yet ifeither opponent discards in hearts or diamonds

a trick willbe set up for North and South in the suit in

which thediscard is made.

A further situation of double triple squeeze can be set

up byintroducing a split three-card pick-up double menace.

In this casethe two-card double menace can be replaced by

a one-carddouble menace.

The ace of clubs is the squeeze-card. The queenof

spades in theopposite hand is a one-card double menace

against bothopponents.The heart and diamond suits in the

North-Southhands are two pick-up double menaces.

On the lead of the ace of clubs North discards adiamond.

If Westthrows a heart, North and South win three tricks in

hearts withthe ace, king and knave of hearts. If West

throws thefour of diamonds, South leads the ten of diamonds,

and West canwin his two aces and no more. If Westthrows

the ace ofspades on the ace of clubs, East is squeezed. He

cannotdiscard the king of spades. A heart discardpermits

South to playthe knave of hearts, forcing West to cover and

setting upSouth\'s eight as a new winner. A diamonddiscard

enables Southto lead the king of diamonds and establishes

a winner inthe diamond suit.

In the following hand South is declarer at a contract of

threeno-trumps.

club and bothopponents are squeezed simultaneously in three

suits.The situation is the same as in Diagram (45). The

spade suit inthe North-South hands is an ordinary two-card

doublemenace, and the heart and club suits are two pick-up

doublemenaces.
