Pseudo-squeeze

Pseudo-squeeze is an "ingenuine" type of squeeze in contract bridge, where the declarer goes through the motions of a squeeze where none actually exists, i.e. simulating a genuine squeeze in the hope that a defender misreads the position and therefore misdefends. It can be regarded a deceptive play—one that may succeed against a defender sophisticated enough to recognize a possible squeeze position.

For example, consider the simple legitimate positional squeeze:BridgeHandNES
4|6|-|A
KQ|A|-|-
AJ|K|-|-The ClubsA is led from dummy in the following position, and East is genuinely squeezed between hearts and spades—if he throws away the HeartsA, declarer discards the SpadesJ from hand, plays hearts and makes the HeartsK and the SpadesA. If he throws away one of the spades, South discards the HeartsK, plays spades, and again makes the two remaining tricks.

Now consider the following layout:BridgeHand
4|6|-|A
J3|4|-|-
KQ|A|-|-
A2|K|-|-Now, seeing all the cards it is obvious that on the play of the ClubsA East can safely throw a spade, as his partner still guards South's Spades2 menace. However, he cannot see declarer's hand and if he throws the HeartsA, then he has been pseudo-squeezed.
Similarly, the position could have been:BridgeHand
4|6|-|A
23|K|-|-
KQ|A|-|-
AJ|4|-|-Now, if East throws a spade on the ClubsA, South makes the rest of the tricks.

Defenders can sometimes avoid being taken in by pseudo-squeezes if they count and signal accurately. Many times, however, the position is simply too difficult. Consider this layout, constructed by Clyde Love [Love, Clyde. Bridge Squeezes Complete. Dover, 1968.] :BridgeHand
K4|8753|AKQ754|8
J8753|J1096|1062|10
1092|42|J983|J754
AQ6|AKQ|-|AKQ9632South plays 7NT and West leads the HeartsJ. As a genuine threat, North's diamonds are useless because they cannot be run, South has no diamond entry to support a genuine squeeze, and three diamond tricks only are no help. South has 13 tricks if the clubs break 3-2, but what if they break 4-1? In that case, only a club discard from length will help.

So South cashes the hearts and then the SpadesK, SpadesA and SpadesQ. It cannot hurt to cut the link between the North and South hands because, as noted, North's diamonds are useless.

But East has a real problem on the sixth major suit trick, because the position makes East believe that he is squeezed. South "obviously" has at least one diamond because he didn't cash diamonds when the lead was in dummy with the SpadesK. So, East thinks he "must" keep his diamonds and hope that West can help guard the clubs, but as soon as East discards a club South has 13 tricks. As Love states, "It would take an imbecile or a genius to discard a diamond!" Notice that neither counting nor a defensive signal can help East here – the crucial decision comes too early.
Here is a pseudo-squeeze by Victor Mollo [Mollo, Victor. You Need Never Lose at Bridge. Faber, 1983.] :BridgeHand
654|876|KJ32|K87
KQJ|J543|9754|54
10987|KQ109|Q1086|6
A32|A2|A|AQJ10932The players were the Hideous Hog (South), Papa the Greek (West) and Molly the Mule (East).

Against the Hog's 6Clubs Papa led the SpadesK. With only one winner in dummy to take care of three losers in hand, the Hog went for the swindle. He won the SpadesA and ran his clubs, stranding dummy's DiamsK in the process. Both Papa and Molly thought that the Hog had DiamsAx in his hand – with the bare DiamsA, the Hog would have cashed the diamond tops before cutting himself off from dummy.
The position with six cards left was:BridgeHand
65|8|KJ3|-
QJ|J4|97|-
-|KQ9|Q108|-
32|A2|A|JWhen the Hog led his final club, Papa thought that he had to keep two diamonds. If he came down to the Diams9, the Hog would cash his DiamsA and lead toward dummy's DiamsKJ. Papa would show out and the Hog would drop Molly's DiamsQ. Papa could not throw a spade, because that would allow the Hog to establish a small spade as his twelfth trick. So Papa threw the Hearts4. Papa was pseudo-squeezed.

Then Molly chose to throw the Hearts9 in order to retain her diamond guard. She was pseudo-squeezed as well, although earlier she had relied on Papa to keep the HeartsJx, so that she could eventually unblock under the HeartsA. The Hog cashed the HeartsA and DiamsA and threw Molly in with a heart to lead up to the DiamsKJ.
