South for Japan opened the king of spades
Declarer won with the ace, discarding a club, and led to his diamond ace. He ruffed two diamonds in dummy, returning to his hand by ruffing spades. On the fourth lead of diamonds South could not gain by ruffing, for it would cost him a trump trick. When he discarded, dummy ruffed and returned a good spade, ruffed by North. East could have made his contract by discarding his remaining club; he also made it readily by overruffing. South also overruffed but could win only one more trump trick and his ace of clubs. Malaya gained a total of 1,390 points.
A high trump would have been a much better opening lead, but even that would not have set the contract. East wins the trump opening with the ace, cashes the diamond ace and ruffs a diamond. On dummy's spade ace, declarer discards a diamond. He ruffs a spade, ruffs a diamond and trumps .another spade, establishing the suit. Next he leads a club. North cannot get in to cash the high diamond. Dummy must gain the lead with the club king and declarer discards his last diamond on a good spade. South can win only two trumps and the ace of clubs.
In spite of the huge swing gained by Malaya on this one hand, Japan won the 64-deal match. So I have warned my teammates to be prepared for some violent action.
When your own hand holds insufficient entries to insure establishment of your suit, it is usually best to duck an early trick. That way, you may leave partner with a card of your suit to lead if he happens to hold the necessary entry.
