This deal is from an EBU online duplicate.
After three passes John Currie sitting South opened one spade leaving North with an awkward call since they were not playing Drury. He chose the underbid of two spades. East bid a rather mysterious three clubs (an unusual two notrump seems more obvious). South then bid three hearts, a long suit game try. North bid four hearts in case South had four hearts and the four four fit would make an extra trick.
A club was led to the ace then East returned a spade. John cashed the king and queen of hearts discovering the four one split in trumps. He next cashed the club king and led a heart to the nine. Now a club ruff in hand was followed by a spade to the king and the ace of hearts to draw the final trump throwing a diamond from hand, then three rounds of spades brought the total to eleven tricks.
There are only ten tricks available in spades, so playing four hearts scored well.
