South won the ten to continue with the club three for the four, ten and king. East switched to the ten of spades covered by the jack and queen. The heart exit was taken by the king and was followed by the club seven for the queen and ace. Declarer crossed to the nine of clubs to lead a diamond for the king and ace. East returned a spade as partner scored two more spades and the game drifted down one, N-S -100.
The Italians long ago employed a Roman Two Diamond opening (17-24 HCP) to show a three- suited hand such as North's. This convention fell into oblivion until it was resurrected with a much lower range. Some partnerships nowadays play Mini- Roman showing 11-15 HCP with a three-suited hand. The distribution can be 4,4,4,1 or 5,4,4,0. North had performed well to describe his pattern without the aid of Mini-Roman. The two club rebid was a white lie since he did not own a fifth diamond. When partner rebid two spades, he continued with three hearts pinpointing the spade shortness but also disclosing a strong hand. He could not hold five diamonds and four hearts as he would have reversed into hearts at his second turn. South could, therefore, conclude that partner's distribution was 1,4,4,4 and opted for the ninetrick game.
