'Not So Elementary'
Autumn 2000, Utrecht, The Netherlands. Professor IMP payed a visit to the first heat of the ING Bank Top Circuit. In fact, he was kibitzing one of the pre-tournament favourites, the Dutch international player Huub Bertens. Due to gross overbidding on several deals by him and his partner, Bertens did not make the top ten in the final ranking. Still, Professor IMP was quite impressed by a defensive coup perpetrated by Bertens.

W/NS    West   North   East    South
                                                  Bertens
              1NT1)   Pass     3NT     Pass
              Pass     Pass
1) 15-17

North led the 10 and this is what Bertens saw:

Declarer let the first heart run to his Jack. Now, Bertens knew that West possessed the A as well, as NS were playing odd leads (1st, 3rd and 5th best). Declarer continued with a small diamond from his hand and North followed with the nine.  the The Jack was played from dummy and South won his Queen. It occurred to Bertens that declarer might be trying to find his ninth trick in diamonds, for partner's nine could well be from A-9 bare. If so, all of declarer's high cards were more or less known. His hand could well be:

A/K 4 2  A J (x)  x x x x (x)  A K x

Huub Bertens realised that although a spade switch would be best, it wouldn't be killing. North would win the Ace or the King, but West could take the second spade, blocking the suit.

Professor IMP turned to his class, asking: 'Does anyone still see a chance for the defence?'

The pupils discussed and analysed the situation, but nobody found a solution. Finally, Professor IMP had to provide the answer himself: 'The contract is indeed ice cold, but not indefensible.'
'It's all a matter of creating an illusion. Huub Bertens returned the Q! This made declarer think he held the K as well.'
At the table, West fell into to the trap and ducked. Who could blame the poor fellow? When North won the next spade and cleared the suit, declarer knew he was doomed - especially after North gained the lead with his A and cashed the fourth spade as the setting trick.
'Not so elementary, this deal, but it did happen,' concluded Professor IMP. The full deal was:
