Teams (20 VP matches)
♠A lead, showing even number of spades when having AK. South plays ♠3 (lavinthal)
North hesitates for 15-20 seconds before playing ♣6. South ducks the ace when dummy plays low.
Result 4♥ = 620 (♠A, ♣A, ♦K)
West calls director. Says that without the long tank before playing the club south would raise with ♣A to try to give a ruff and defeat the contract, which would result on an overtrick. South says that playing that way he sets up all of dummy's clubs for discards and doesn't make sense.
