Main Guide 9GC8 by Richard Pavlicek
Each diagram shows the described technique for North-South in its simplest form (2-7 tricks) and the number of tricks N-S must win (goal). South is always on lead unless an opponent is required to lead, then West. If there is a trump suit, it is always spades.
Essential plays are shown, pursuing the most likely path if variations exist. Key plays are followed by an exclamation point (!). If West is on lead, a question mark (?) after the lead means its a losing choice for the ending but likely in practice and forced for the technique.
|auto||(automatic) Same technique* works with the East-West hands switched|
|auto?||Goal is achievable with East-West switched but by a different technique|
|bi||(bidirectional) Same technique* works with the opposite hand on lead|
|bi?||Goal is achievable with opposite hand on lead but by a different technique|
|re||(reciprocative) Squeeze card ( A) may be in the opposite hand|
|not||Goal is impossible with best E-W play (technique only offers a chance)|
|not?||Goal is achievable after Wests forced lead but not after Wests best lead|
*or simply winning any trick possible if the case becomes trivial
|Threat suit||Spades (downward as needed)|
|Winner||Ace (downward as needed)|
|Threat card||Highest partnership non-winner in suit|
|Essential card||Four (upward as needed)|
|Idle card||Two or three|
|Squeeze card||A (or A if in trumps)|
An idle card opposite the squeeze card ( A) is generally shown in clubs as an aid to visualizing reciprocative positions. This makes the ending bidirectional by definition. If the idle card were in a threat suit instead, the ending is usually not bidirectional.
No attempt is made to distinguish which technique might be correct on any given occasion. For example, the Finesse category does not profess when and when not to finesse an exhaustive study in itself subject to many factors but only the available techniques.
Deceptive play is also ignored. Almost any technique can be applied as a psychological bluff, so deceptive play is usually just an attempt to disguise the actual technique. Further, studying all the fakes could land you in the nut house fast. No problem. Plenty of room in my ward!
