The above slam was bid by
Michael Newman (West) and Michael Byrne (East).

A good way of playing a jump to three diamonds over one notrump is to show at least 5-5 in the minors game forcing with possible interest in slam.  Over three diamonds if opener is very strong in the majors and has no interest in playing in a minor suit then he bids three notrump.  If opener wishes to set clubs as trumps he bids three hearts while if opener wishes to set diamonds as trumps he bids three spades.  The beauty of this is that responder knows which trump suit has been agreed.

After agreeing clubs by rebidding three hearts East and West showed controls in spades and diamonds.  Finally when East showed a heart control with a bid of four hearts (doubled by South) West knew that there was no danger of there being two losers in hearts and so was able to bid Roman Key Card Blackwood for clubs reaching the excellent slam with a combined 25 points.  North opened with a heart lead but there were no problems in the play and a score of 1370 to East West resulted.  (Note that in the play of the trump suit it is important to start off with the ace in case North started with J10xx).  The amusing thing about the auction was that the final bid was the first time that the trump suit had actually been bid!

In the other room a less sophisticated auction left West playing three notrump, fortunately for the opposition North had a natural spade lead.


Thanks to Michael Newman for reporting this deal
