Slam Bidding by David

A: 3♣. In most systems, a rebid of 3♠ is invitational but not forcing. Mullamphy therefore showed his game-forcing strength with a fourth-suit forcing bid of 3♣.

Your result so far:

A: 3♥. The auction was already forcing-to-game, so Klinger bid just 3♥ to see what would happen next.


Your result so far:

A: 4♣. East had shown powerful spades and Klinger was happy to accept that suit as trumps, for the time being. Since he had a great hand, he could not contemplate bidding just 4♠. He bid 4♣ to agree spades as trumps and show a control in the club suit.



Your result so far:

A: 4NT. Klinger bid 4NT, Roman Keycard Blackwood, to ask how many keycards East held. The responses are: 5♣ 1 or 4 keycards, 5♦ 0 or 3, 5♥ 2 keycards but no queen of trumps, 5♠ 2 key cards and the queen of trumps.

Your result so far:

A: 5♠. Mullamphy held two aces and the ♠Q, so he responded 5♠ to RKCB.

Your result so far:

A: 5NT. Klinger might just have bid 7♠. He decided to ask for side-suit kings by bidding 5NT (just in case East's 4♦ control bid had been made on a singleton instead of the ♦K).

Your result so far:

A: 7NT. Now we see the point of the 5NT bid. On hearing about the ♦K, Klinger could count 13 tricks in no-trump. He ended a fine auction by leaping to 7NT.
