After East opened one diamond, Kaplan (South) decided that he was unlikely to find out if his partner had the right cards for a slam, so he tried to end the auction with his four-spade jump overcall.
Meckstroth's three-spade jump overcall would usually show some 14 to 16 high-card points, but opposite a passed partner, he wanted to try to make life harder for the responder on his left.
Hence: "One of these days in your travels, a guy is going to come up to you and show you a nice brand-new deck of cards on which the seal is not yet broken, and this guy is going to offer to bet you that he can make the Jack of Spades jump out of the deck and squirt cider in your ear.
Willenken (North) responded two clubs, Stayman, and then, over two spades, jumped to four clubs, Roman Key Card Blackwood.
In this auction, after East's two-spade weak jump overcall, showing six spades and some 5-10 high-card pointSouthuth's three-club response is game-forcing, so is an overbid.
At the other table Brown (West) opened one club because she was using the weak no-trump, Khonicheva (North) produced an unorthodox two-spade weak jump overcall, Stockdale (East) made a negative double, Gulevich (South) raised to four spades, West doubled, and all passed.
Then Ehlers (North), expecting his partner wouldn't have two spade losers, jumped to six hearts, which was passed out.
Dennis Clerkin (North) judged better, first responding one spade, then jumping to game when his brother showed a club suit.
West surely has at least six spades to jump to game on the second round with limited high-card power.
After Leon Jacobs (North) rebid two clubs and Cezary Balicki (East) passed, Maarten Schollaardt (South), knowing about the club fit and loving his wonderful spade suit, jumped to four spades.
Their bidding began similarly, but after four spades South jumped to six clubs and North continued to seven clubs.
