How would you defend as WEST on the hand above?
Opening lead K♣ (asks for count) and partners card shows an Odd number of cards in clubs.
a. If partner plays the 5♣ and declarer follows with the 3♣ at trick 1?
b. If partner plays the 5♣ and declarer follows with the J♣ at trick 1?
THE SAME !
You need to switch to a Heart at trick 2.
You need 4 tricks to beat this contract 1 Heart, 1 Diamond and 2 Clubs. If you make the mistake of cashing your Club tricks first and then switching to a Heart, declarer will win with the A♥. After drawing trumps, ending in hand, he will cash his remaining top Club trick, throwing the losing ♥3 from dummy and make cackling noises as he clocks up +620 instead of -100.
TIP - Think WHERE are you tricks coming from to beat a contract before just trying to cash them off the top.
