• 2♥ :  P/C,  searching for the major with 6 cards. An opener with semi-forcing values, bids 3x. If strong and balanced, he rebids 2NT, preparing a possible Niemeyer continuation.

• 2 ♠ : P/C, holding a good hand for a hearts contract : opener passes with 6c , bids 3♥ when min with ♥, and 4♥ when max w. When holding a semi-forcing hand in a minor or spades, he will bid the suit on 3 level.

• 2NT : RF, 14+ hp,   interrogative . Opener has following options :

• 3♣/♦: 6c  ♥ / ♠  with 6-8 hp
• 3♥/♠ :  6c ♠  / ♥   with 9-10hp . ATTENTION : mark the switch between the majors in order to let the strong hand play
• 3NT : very unlikely, but the strong variant. Up towards slem !
• 4♣/♦  : semi-forcing hand in the minor

If opener rebids 2NT, showing the strong balanced hand, Niemeyer can be started (3♣) when holding at least a 3card M. Indeed, the opener possibly holds a 5 card major.

A partner with 10+hps may show slem ambition , especially when holding a 5+ card.
