*5+ spades and 5+ of either minor
**Some values in context
Terence Reese classified bids such as two hearts as extremely dangerous if the bidder’s side did not play the hand. Reese believed that, in such cases, declarer could often adopt an almost double dummy line to bring home an otherwise tricky contract.
West began by playing the ace of diamonds followed by the king. Declarer ruffed the second diamond low then cashed the ace of spades. After ruffing the five of spades in dummy, declarer played a trump to his king.
East took the next trump with the ace to lead a third diamond. This return marked West with a 5=1=5=2 distribution originally and East with a corresponding 3=4=3=3 shape which, in turn, allowed declarer to be certain that there was no remaining link between the defender’s hands as East had 1=1=0=3 shape remaining.
So, declarer ruffed the third round of diamonds and played his last trump, throwing dummy’s remaining diamond. After cashing the king of spades, declarer had the queen of spades and the ace-third of clubs left, while East was down to the nine of hearts and queen-ten-third of clubs.
When declarer played the queen of spades, East had a choice of unpleasant outcomes. If he ruffed, he would be endplayed and declarer would make three club tricks and his contract. If instead East discarded a club then the queen of spades would be declarer’s eighth trick with the ace and king of clubs to come. As a result, East folded his cards and conceded the contract to declarer
