A Bergen hand South Dealer Hand 1 South North ♠ A106 ♠ KQ7654 ♠ 9 ♥ AQ3 ♦ AJ964 ♦ K2 ♣ KQ2 ♣ 98 The biding goes: South North 1♦ 1♠ 3♠ 4♦ 4♥ (1) 4NT (2) 5♥ 6♠ Bergen’s comment: North’s 4♦ bid denies a ♣ control, the suit bypassed. So if South does not have a ♣ control either, he would sign off in 4♠. Because South did not sign off, he has to have a control. (1)The 4♥ bid shows first or second round control in hearts. (2) North now bids 4NT to reach the lay down slam. My hands Hand 2 South North ♠ AJ106 ♠ KQ7654 ♥ J10 ♥ AKQ ♦ AQ964 ♦ K2 ♣ QJ2 ♣ 98 The biding goes: South North 1♦ 1♠ 3♠ 4♦ 4♠ P My comment: North’s 4♦ bid denies a ♣ control, the suit bypassed. South does not have a ♣ control either so signs off in 4♠. ---------------------------------------- Hand 3 South North ♠ A1063 ♠ KQ7654 ♥ 94 ♥ AK3 ♦ AJ105 ♦ K2 ♣ AK2 ♣ 98 The biding goes: South North 1♦ 1♠ 3♠ 4♦ ??? 1.A bid of 4♠ by South would deny a ♣ control! 2.
