 Just Short of a Forcing Auction 

East's minimal opener loomed larger opposite West's encouragement.
Having promised only 3 diamonds, having an expected 4 for the 1 opener, 2.5 quick tricks on defence at favourable vulnerability seemed better than risking a nebulous 5 contract that may or may not be raised to slam.
No forcing auction had been established (Pass would not have been forcing).

West started a diamond to East's A.
East's 4 was led to try to encourage a club switch.
West won the J and switched to a club, won by East's K
Two more spades and a diamond finally had declarer on lead, down 3 so far (-800) with the offside K to be lost.

The Law of Total Tricks was again disproved.
