A Record-Setting Auction

Just yesterday I posted an article on the the worst play ever.  This one is pretty remarkable as well:

My partner lost the obvious six tricks, for -150.  Despite the standard interference-bid of 2♠, south had two opportunities to come to life with what was a very fine hand opposite a takeout double of hearts.

Even a reasonable contract of 6♦ or 6♣ would have earned a top on the board.  As it was, my opponents achieved a rare coup with the combination of allowing us to play an undoubled game contract and not making a single bid, when a grand slam was there for the taking!
