    Finesse - A lead towards an opponent's possible winning card, 
    anticipating an opportunity to trap the intervening card. 
    South leads a 
        S9, 
        anticipating West may have the missing 
        SQ onside.  
    With this holding, whether West plays the 
        SQ or not, South will win 4 tricks using a finesse strategy 
    (repeating the finesse when West ducks playing the SQ).  
        If South immediately played the SA and SK, West would win the 
    SQ on the 
        third trick.  
    Here we have a two-way finesse opportunity -- guessing East 
        has the SQ, South could lead a SJ from North, playing a low Spade from 
        South.  If East ducks, repeat the finesse.

    Suit Combinations 
    Here are some samples of finessing scenarios: 
  
    |   | A Q 4 |   |  
    |   |   | Play low toward 
    Q |  
    |   | 4 3 2 |   |  
 
  
    |   | K Q 5 |   |  
    |   |   | Play low toward 
    Q,
    if opponent does not play A, repeat sequence |  
    |   | 4 3 2 |   |  
 
  
    |  | A 5 4 |  |  
    |  |  | Play Ace then low toward 
    Q |  
    |  | Q 3 2 |  |  
 
  
    |   | A J 4  |   |  
    |   |   | Cash K, then play low
    toward J |  
    |   | K 3 2 |   |  
 
  
    |   | A 3 2 |   |  
    |   |   | Play Q, if opponent does not play 
    K,
    repeat sequence |  
    |   | Q J 10 |   |  
 
  
    |   | A J 10 9 |   |  
    |   |   | Play low toward 
    J, repeat low toward 10 |  
    |   | 4 3 2 |   |  
 
  
    |   | A J 9 |   |  
    |   |   | Play low toward 
    9, repeat low toward J |  
    |   | 4 3 2 |   |  
 
  
    |   | K J 10 |   |  
    |   |   | Play low toward 
    J, repeat low toward 10 |  
    |   | 4 3 2 |   |  
 
  
    |   | A Q 10 |   |  
    |   |   | Play low toward 10, repeat low toward 
    Q However, 
    try not to break suit the suit, 
    seeking an endplay. If desperate, try low to J 10  once, then cash A, 
    hoping to trap honor or doubleton K or Q |  
    |   | 4 3 2 |   |  
 
  
    |   | A 3 2 |   |  
    |   |   | Play low toward 10, repeat low toward 
    J |  
    |   | J 10 4 |   |  
 
  
    |   | Q 9 5 2 |   |  
    |   |   | Play low to K (away from
    Q 9 tenace first) |  
    |   | K J 4 3 |   |  
 
  
    |   | A 3 2 |   |  
    |   |   | Do not break suit, 
    seek an endplay. If desperate, try low to J 10  once, then cash A, 
    hoping to trap honor or doubleton K or Q |  
    |   | J 10 4 |   |  
 
  
    |   | A 3 2 |   |  
    |   |   | Similar to the 
    above, first play low to the 9 before cashing the A |  
    |   | J 9 4 |   |  
 
  
    |   | A K J 6 |   |  
    |   |   | Holding an 8 card 
    suit, first play the A hoping the opponent drops the Q or 
    perhaps the 10 (Restricted Choice), then finesse the Q if 
    opponents both play low |  
    |   | 5 4 3 2 |   |  
 
  
    |   | A 2 |   |  
    |   |   | Do not break suit, 
    seek endplay.  If slam, consider squeeze (play A and make 
    opponent guard K) |  
    |   | Q 3 |   |  
 
  
    |   | A 3 2 |   |  
    |   |   | Simple approach is
    A then finesse opponents' K. If opponents' have 3 of top 7 (K 
    J 10), declarer holds 4 of top 7 – A Q 9 8. With endplay and squeeze 
    opportunities, watch opponent suit discards, first playing other suits |  
    |   | Q 9 8 |   |  
 
  
    |   | A 4 3 2 |   |  
    |   |   | Typically cash 
    A then finesse opponent’s Q.  Carefully watch count, signaling, 
    leads, inferences.  |  
    |   | K J 6 5 |   |  
 
  
    |   | A K Q 10 |   |  
    |   |   | Opponent 4-2 
    “a-priori” break is 48% and 3-3 is 35%.  Consider defender play tactics, 
    watching count and Restricted Choice clues. |  
    |   | 4 3 2 |   |  
 
  
    |   | Q 3 2 |   |  
    |   |   | Take early 
    finesse toward hidden stiff K. Plan play before playing to trick 1, 
    proceeding early to make a smooth play |  
    |   | K |   |  
 
  
    |   | K 10 5 |   |  
    |   |   | Depending on 
    auction level, endplay may be mandatory.  But simply first playing 
    toward the 10 brings up odds from 50% to 62%.  In Notrump contracts 
    consider dangerous opponent |  
    |   | 4 3 2 |   |  
 
  
    |   | A J 10 |   |  
    |   |   | Basic repeated 
    finesse with 76% chance to make 2 tricks |  
    |   | 4 3 2 |   |  
 
  
    |   | A Q 10 |   |  
    |   |   | As above, 76% 
    chance to make 2 or a 24% chance for 3 tricks |  
    |   | 4 3 2 |   |  
 
  
    |   | A Q 9 |   |  
    |   |   | Same idea here, 
    finessing to the 9 has a 63% chance to make 2 |  
    |   | 4 3 2 |   |  
 
  
    |   | A 3 2 |   |  
    |   |   | Cash A then 
    play low to Q 10 hoping Right Hand Opponent makes life easy.  |  
    |   | Q 10 4 |   |  
 
  
    |   | A 3 2 |   |  
    |   |   | Finesse toward 
    Q J – never lead Q or J (unless only 2 
    tricks are needed). If Q holds, 
    play toward A and repeat finesse to J to make 3. |  
    |   | Q J 5 4 |   |  
 
  
    |   | A 3 2 |   |  
    |   |   | Same as above, 
    although with 8 card suit cash the A first (Rabbi rule dropping K) |  
    |   | Q J 6 5 4 |   |  
 
  
    |   | A J 3 [2] |   |  
    |   |   | When playing for 3 
    tricks, never lead Q. Play toward J and then 
    cash A; holding 4 cards, the declarer can actually make 4 if opponent carelessly 
    discards one card and partner holds K x or if opponents are 3-3 and 
    one mistakenly goes up on repeated finesse.  However if West is marked with 
    honors, cash A and then finesse West for K x |  
    |   | Q 4 3 |   |  
 
  
    |   | A K J |   |  
    |   |   | Play A,  
    then finesse the Left Hand Opponent's Q |  
    |   | 4 3 2 |   |  
 
  
    |   | A K 10 4 |   |  
    |   |   | Play A (hoping West holds Q x), next low toward 10, then cash K. |  
    |   | J 3 2 |   |  
 
  
    |   | A Q 10 3 |   |  
    |   |   | Play depends on 
    entries.  With entries, tempt with the J and West will likely cover 
    holding K.  Without entries, play 9 and West will not cover – 
    then play J |  
    |   | J 9 2 |   |  
 
  
    |   | A Q 9 3 2 |   |  
    |   |   | Holding 
    intermediates with side suit transportation problems, consider unblocking 
    maneuvers.  Lead the 10 to the A (not low to A), then
    low to K – the only way to make 4 when West is long in the 
    suit |  
    |   | K 10 4 |   |
