A deal from the Cumbria/Norfolk Swiss Pairs.
Dealer S N-S vulnerable.
Online bridge means there are some strange competitions.
Norfolk and Cumbria merged their green point Swiss weekend competitions in March and attracted a large entry from all over the country.
This deal found many declarers (including me) having a blind spot.
North South flirted with bidding a slam, but ended in four spades.
West led the club king. How do you play?
To retain control play a small trump towards dummy at trick two. If spades split 3-2 then twelve tricks are easy.
When they split 4-1, as they did at the table, if East takes the spade king, South can then draw trumps, fortunately the ten was singleton.
If East tries ducking the jack of spades, South can take the spade finesse and then cross to the heart ace and take another spade finesse, draw trumps and make all the tricks.
