Dealer N Game All.
This deal is from the Tollemache qualifying event last month.
West leads the jack of clubs, you play low from dummy, West wins with the king and returns the seven of clubs.
How do you play?
If you play on diamonds and the clubs are 5-2 you are in danger of losing three clubs, two spades and a trick in each red suit before you can make seven tricks.
Playing on hearts is a better chance, but you will still need three heart tricks which isn't guaranteed.
If instead you win the second club in hand and play the queen of spades and then play the jack of spades when you win the third club you will succeed when West has the ace of hearts or if East has the ace of hearts and the hearts come in, with some additional chances in the diamond suit if West has no entry.
