You could play a lifetime of bridge without pulling off a Devil’s Coup, but it’s worth a look purely for its entertainment value.

 

 

It looks like Partner has overbid again because you find yourself in the dreadful contract of 6♠.  West cashes the ♥A at Trick 1 and now the success of your slam depends upon losing no trump tricks, missing QJ873.  The chances of one defender holding QJ doubleton are pretty remote (8%, actually) and you can do better by not drawing trumps.

 

At Trick 2, you ruff the Heart continuation, cash three Diamonds (ending in Dummy), ruff another Heart, cash ♣A and ♣K, and ruff a Club, reaching this position, with the lead in Dummy: 

 

Do you see how to win the rest of the tricks?
