This is the rare and beautiful positional cousin of the blocked simple squeeze in which there is no overtaking option in the blocked suit because the blocked winner is the highest remaining card in the suit. Instead, South cashes the club A, and if West discards a spade, North takes the last two tricks with the heart A and the spade K, while if West discards a heart, North jettisons the heart A to allow South to cash two heart tricks.

Variations

In spite of the delicacy of the jettison mechanism, the jettison squeeze has almost the same significant variants as the blocked squeeze.

1) Idle cards: The diamond 2 in the diagram is an idle card, but in this case the only possible replacement is a low spade (a heart would unblock that suit, while a club would prevent the jettison).

2) Extra winners: There are exactly the same 48 possibilities as for the blocked squeeze. For completeness, here is the schematic diagram from the blocked suit squeeze, with the minor modifications necessary for the jettison variation:

South to lead:

spade symbol (n winners) + (s + 1 - f losers)
heart symbol A
diamond symbol(f idle cards)
club symbol --

spade symbol (n + 1 cards)
heart symbol (s + 1 cards)
diamond symbol --
club symbol --

spade symbol--
heart symbol (s winners) + (n + 2 - f losers)
diamond symbol --
club symbol (f winners)

All hands in this ending have n + s + 2 cards; if West discards a spade on South's next free winner, then South cashes any remaining free winners, and crosses with a low heart to the established North hand; if instead West discards a heart, North jettisons the heart A so South can run the hearts from the top. Note that North's idle cards must all be in diamonds and spades (heart or club losers would unblock the ending).

The numbers n, s, and f must satisfy four conditions:

(A violation of either of the first two conditions would mean that North-South have the rest of the tricks without resorting to a squeeze; the third condition says that North, South, and West can have at most 13 spades between them; the fourth condition says the same thing about hearts.) This leaves no fewer than 48 possible values for n, s, and f, tabulated below:

The five sample endings in this article illustrate the cases 0, 1, 1; 0, 2, 1; 1, 1, 1; 1, 2, 1; and 1, 2, 2 respectively.

Note that in the positions with f > 1, the jettison squeeze is no longer positional (that is, it will work against either opponent):

n = 1, s = 2, f = 2

 

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

 

 

spade symbol K Q
heart symbol J 10 9
diamond symbol --
club symbol --

 

spade symbol --
heart symbol K Q 8
diamond symbol --
club symbol A K

 

Here South cashes the club A, and East is squeezed while North still has an idle card. If East discards a spade, then South discards North's last diamond on the club K, and the North hand is high; if East instead discards a heart, then South can jettison the heart A on the next trick, when the club K is cashed. This observation is the key to the existence of the jettison double squeeze.

3) Losing squeeze card: The only condition here is that the far threat must include a winner if that suit might be returned when the squeeze trick is lost.
