Weinstein (West) passed first, then overcalled two spades after Platnick (North) made a two-diamond transfer bid into hearts.
Although South had only a minimum 15 points, there was a case for jumping to three hearts over the two-diamond transfer response, making what is called a super-accept.
After West, presumably because of the prevailing vulnerability, decided not to show his second suit (three spades can be defeated by two tricks), Judi Radin (North), a four-time world champion, responded with a three-diamond transfer bid and passed when her partner only completed the transfer.
(For the theorists, I like to play that this three-diamond bid shows five-plus hearts and a hand that is either weak or worth at least game. A three-heart response would invite game with five-plus hearts. After a two-heart opening and a two-no-trump overcall, a three-diamond transfer is game-invitational in spades; a three-heart transfer is either weak or strong).
In the given auction, Carmichael (North) responded one diamond, a transfer promising four or more hearts.
North responded two diamonds, a transfer bid indicating five or more hearts and any point count.
Joel Wooldridge (North) responded two diamonds, a transfer bid indicating five or more hearts with any point count.
Perhaps those nine times the contract was played by South after he opened with a weak no-trump, and North made a four-diamond Texas transfer.
Your partner responds two diamonds (a transfer) and rebids three no-trump, showing five hearts and offering you a choice of games.
He opened two no-trump; his partner responded three diamonds, a transfer bid; and Johnson jumped to four hearts, a superaccept showing four-card heart support, usually a side-suit doubleton and a hand good for playing in hearts.
Sections 1 μm thick were prepared from these samples with a diamond knife, transferred to quartz microscope slides, and embedded in glycerine [ 33].
