Board 21, NS vulnerable, North deals.
Rod East Doug West 1NT Pass 2♣ 3♣ 3♥ Pass 3NT Pass Pass PassA spade lead would have beaten this, but East was understandably deterred by the auction's implication that South had four spades and chose a diamond instead. I managed to set up hearts for a total of 10 tricks and 98% of the matchpoints.
