Criss-Cross 1-Loser Triple Squeeze

[ Home | Catalogue | 1-Loser Triple Squeeze Index ]

The criss-cross family of 1-loser triple squeezes includes four positions in which at least one of the threat suits is blocked, the equivalent of Qx opposite A, requiring a re-entry to the blocked threat in another suit, which will either be another blocked suit as in the criss-cross simple squeeze, or an extra entry in the free suit, or a ruff. There is one further position in which the blocked threat is replaced by a ruffing threat, as in the ruffing simple squeeze.

Blocked menace:
1) Re-entry in free suit:

 

spade symbol A J
heart symbol --
diamond symbol A
club symbol 3 2

 

 

 

spade symbol K Q
heart symbol A
diamond symbol K Q
club symbol --

 

spade symbol --
heart symbol K
diamond symbol J 2
club symbol A K

 

2) Ruffing re-entry:

 

spade symbol K 2
heart symbol K
diamond symbol A
club symbol --

 

 

spade symbol K Q
heart symbol K Q
diamond symbol K Q
club symbol --  

 

spade symbol --
heart symbol --
diamond symbol J 3
club symbol A 2

 

3) Re-entry in second blocked threat (free winners split):

 

spade symbol J 2
heart symbol --
diamond symbol A
club symbol K 2

 

 

spade symbol K Q
heart symbol A
diamond symbol K Q
club symbol --  

 

spade symbol A
heart symbol K
diamond symbol J 2
club symbol A

 

4) Re-entry in second blocked threat (free winners together):

 

spade symbol J 2
heart symbol A J
diamond symbol A
club symbol 2

 

 

spade symbol K Q
heart symbol K Q
diamond symbol K Q
club symbol --  

 

spade symbol A
heart symbol --
diamond symbol J 3 2
club symbol A K

 

In position 2), North's idle card can lie in any suit, although if it is in clubs, then the other opponent must have a trump with which to interrupt the potential cross-ruff, and if it is in diamonds, then the squeeze against West would reduce to a split positional simple squeeze.

In position 4), if South's idle card is in hearts, then the position reduces to an automatic simple squeeze in the red suits by cashing the diamond A and the spade A before playing clubs. If South's idle card is in spades and East holds the guards, the position reduces to a split positional simple squeeze in the pointed suits by cashing both clubs, the diamond A, and the heart A. If North's idle card is in diamonds, the position reduces to a twin-entry simple squeeze in the red suits by cashing all black winners.

These are the only restrictions on the idle cards.
5) Ruffing menace:

 

spade symbol K
heart symbol K
diamond symbol --
club symbol 3 2

 

 

 

spade symbol A
heart symbol A
diamond symbol A K
club symbol --

 

spade symbol --
heart symbol --
diamond symbol Q 2
club symbol A 4

 

Again, the squeeze is only necessary if the other opponent can interrupt the cross-ruff. This is the only 1-loser triple squeeze which involves a true ruffing menace - in other ruffing 1-loser triples, the ruff is needed only to provide an entry.
