The jettison squeeze is a rare variation of a
simple squeeze. It occurs when declarer holds a menace that's blocked by a high card in dummy. Declarer may need to discard (unblock) that high card to complete the squeeze.
In the following layout, South's club menace is blocked by dummy's ace.
| | Dummy | | |
|  K9 | |
|  — | |
| West |  — | East |
| A |  A | T |
| — | | 43 |
| — | South | — |
| 98 | — | — |
| Q | |
| — | |
| T2 | |
South is on lead. When she leads the Q, West gets squeezed. If West discards his A, dummy's king becomes good. But if West opts to discard a club instead, South must jettison the A from dummy. This allows her to score the last two tricks with the T and 2.
Example
The following deal is from Terence Reese's short but amazing book, "Master Play in Contract Bridge".
| | Dummy | | |
| QT654 | |
| KQ | |
| West | Q97 | East |
| K982 | J43 | J7 |
| T63 | | A8752 |
| A85 | South | 43 |
| T97 | A3 | KQ85 |
| J94 | |
| KJT62 | |
| A62 | |
"South played in 2NT and West opened 10. South held up until the third round and played diamonds. West waited to see partner's discard on the third diamond; then he switched to a heart, and the queen lost to East's ace. East cashed the thirteenth club, South threw a spade, and led 7, taken by the ace. After a fourth diamond the position was:
| | Dummy | | |
| QT | |
| K | |
| West | — | East |
| K | — | J |
| T6 | | 85 |
| — | South | — |
| — | — | — |
| J9 | |
| T | |
| — | |
"South led 10 and when West threw a heart, had only to keep his wits about him and discard K from dummy. This artistic squeeze can be played only against the left-hand opponent, that is, it is a one-way squeeze."
