The Full Deal
On this layout, the Ace of diamonds lead gives declarer the contract. Similarly, if West leads the Ace of clubs and then cashes the Ace of diamonds, that also gives declarer the contract. Minus 620 scores 14% and plus 100 scores 67%.
Bonus from Val: If West leads the Ace of clubs, that gives declarer a trick but EW still defeat the contract so long as West doesn’t lead a diamond next. Deal L021.
