Bridge card game, the most popular card game in the world |
A simultaneous double squeeze is a double squeeze the card game contract bridge in which both opponents are squeezed by the same squeeze card. There are three basic matrices:
♠ | A2 | ||||
♥ | K | ||||
♦ | - | ||||
♣ | - | ||||
♠ | Q6 |
N W E S |
♠ | K9 | |
♥ | A | ♥ | - | ||
♦ | - | ♦ | Q | ||
♣ | - | ♣ | - | ||
♠ | 3 | ||||
♥ | - | ||||
♦ | J | ||||
♣ | 2 |
1) When the club deuce is played West has to shed a spade, dummy sheds
the now useless king of hearts and East is squeezed in the
pointed
suits. This is a
positional squeeze.
♠ | A2 | ||||
♥ | K | ||||
♦ | J | ||||
♣ | - | ||||
♠ | QJ9 |
N W E S |
♠ | 1085 | |
♥ | A | ♥ | - | ||
♦ | - | ♦ | Q | ||
♣ | - | ♣ | - | ||
♠ | K64 | ||||
♥ | - | ||||
♦ | - | ||||
♣ | 2 |
2) The two of clubs is cashed and again West has to give up the guard in
the double menace suit (spades). The now useless king of hearts is played from
dummy and East is squeezed in the
pointed
suits. This is a
non-positional squeeze - we can swap the hands of East and West - but it is
not an
automatic squeeze as was (1). We have to know who guards each red suit.
♠ | AK2 | ||||

♦ | 2 | ||||
♣ | - | ||||
♠ | QJ9 |
N W E S |
♠ | 1085 | |

♣ | - | ♣ | - | ||
♠ | 4 | ||||
♥ | Q | ||||
♦ | Q | ||||
♣ | 3 |
3) This is the most comfortable endposition of the three simultaneous
double squeeze matrices. Simply because this squeeze is
automatic and
non-positional. We can swap the hands of East and West and we discard the
two of diamonds on the three of clubs without any reflection. We know that, as
long as the squeeze worked, all spades in the North hand must be winners, unless
one of our two queens became a master.
