This swingy deal is from the final day of the Northern Bridge League.
West opened a minimum one heart, North showed the minors with an unusual notrump call. Now East showed a good raise to three hearts or better by cue bidding three clubs. South now had a long think and emerged with six clubs, knowing that there was a 12 card fit. West had nothing to say, East tried six hearts presumably as a two way shot, either a good sacrifice or it might make on a good day. These wildly distributional deals are very difficult, often it is right to bid one more as insurance. North led the ace of clubs, West ruffed, crossed to the king of diamonds and ran the ten of hearts. Now South got a diamond ruff for two off. Here six hearts would have made if declarer had guessed the trumps correctly, six clubs was going off.
The deal was played twelve times. Four tables played in seven clubs doubled, two in six hearts, three in six clubs doubled, the others in five hearts or spades.
