4 Invitational (but why in heaven's name does North go over 3NT when holding a 4-3-3-3?)

'Skilfully' NS have avoided bidding 3NT - which is on ice - in order to bid the more challenging contract of 5 (probably the worst bid was 4 - 3 would have been better - but South is not innocent either: he probably had better opened 2 and rebid 3NT).

West leads the J, declarer ducking in dummy. East wins with the K and switches to a small club. How should South play?

Solution
 
Unblocking**

This page usually contains a piece of theory, in this case about 'Unblocking' , including an example (or two).
Three exercises will follow, one in each of the next three weeks (click 'Varia**').

Sometimes a partnership cannot, despite having all high cards in a suit, cash all its tricks in that suit at once, since the suit is blocked.

Last month in these columns we studied some of the consequences of a blockage (starting here). We focused on blocking an opponent's suit. This time the topic will be unblocking: the preventing or lifting of a blockage.
En example from a team match (IMP scoring):
