Nowadays fewer and fewer of the top players are playing a double of a strong No Trump as penalties, but is a 14-16 No trump weak or strong? 

Jason and Justin used to consider it a strong No trump, but have recently changed and deem it to be weak. Thus they can double for penalties.

Let us turn our attention to North after his partner has made a penalty double. Should he pass and hope it goes off or should he bid and try to get to a better contract? Everyone has different views.
