The 1987 change, to the scoring of the fourth and subsequent non-vulnerable undertricks, was made after a hand in the finals of the 1981 Bermuda Bowl. Munir and Fazli, playing for Pakistan, bid skilfully to reach a vulnerable 7 hearts, which would have scored them 2210. But their non-vulnerable Meckstroth then sacrificed in 7 spades on a weak hand with fives spades to the jack. This went nine off doubled for a score of -1700, a profitable sacrifice. The change of scoring increased the penalty from -1700 to -2300.
