BRIDGE CONCEPT: FINESSE
RELATED OFFENSIVE
TERMS
  • Lead Through - As in "lead through strength." You play, the strong hand plays, then partner gets a chance to play.
  • Lead Up To - You do not want to "lead up to a tenace." If you see an A-Q in the dummy, and you play first and dummy plays last, do not lead that suit if you or partner has the King.


  • Leading towards a tenace, any sequence missing an intervening card, in the hopes that intervening card is onside and you can decide to play your high or low card after the opponent has played.
  • Absent other information a finesse has a 50% chance of succeeding.
  • From Watson's The Play of the Hand - A finesse is a "play which is sure to win a trick if the higher missing honor is in a favorable position."




  • Onside - The card you seek is favorably placed so that the finesse will work. Bidding and play may reveal clues.
  • Offside - The card you seek is unfavorably placed and the finesse will NOT work.




RELATED PLAYS CONTRAINDICATIONS
  • ruffing finesse - Leading from a sequence towards a void, planning to ruff if covered and discard if not covered.
  • finesse a single honor - Leading towards an honor, such as the king, hoping first opponent rises with the ace to set up your king, or ducks and lets your king win.




  • Bidding indicates intervening card is offside.
  • Better than 50% chance exists elsewhere.
  • Other opportunities can be safely tried first. (Cashing winners, playing for a drop)
  • Dangerous defender could gain lead.
