Classification of squeeze

There are several possible classifications of squeezes, depending on the position. Most common ones are named, some involving a combination of factors:

  • According to the operation of squeeze:
    • In automatic squeeze, either opponent can be squeezed (provided he protects appropriate suits).
    • In positional squeeze, only one particular opponent can be squeezed.
  • According to number of opponents squeezed:
    • Single, where only one opponent is squeezed
    • Double, where both opponents are squeezed
  • According to number of suits involved:
    • Two-suit squeezes, where menaces in two side suits are involved
    • Three-suit squeezes
    • Single-suit squeeze is peculiar and rare, and presents a specific type of endplay rather than "real" squeeze.
  • According to the gain:
    • In material squeezes, opponents are forced to give up a trick directly;
    • In non-material squeezes, opponents are forced to give up strategic position; the extra trick, however, may materialize later. For example, an opponent can be squeezed out of a card which disturbs declarer's entries, or an exit card.
  • According to the count rectification:
    • In squeezes with count, the count is rectified before the squeeze card is played, and declarer will not concede any tricks (they're strongly related with material squeezes).
    • In squeezes without count, the count is not rectified; often, it involves a throw-in in the end position (strongly related with non-material) squeezes.

The following articles describe the mechanisms of different types of squeezes:
