Development after 1N 2 or 2
Opener either accepts the transfer at the lowest level or with a maximum NT, bids 2N with 3 card support or jumps in the long major with 4 card support.
Development after 1N 2 or 2N
Opener bids the “slot” (the bid between the 3 level of responder's suit and the call that responder made) if he “likes” his hand in terms of strength and supporting cards. Otherwise he bids the indicated suit at the 3 level.
Development after 1N 3 or 3
Responder has shown a black suit singleton (3) or a red suit singleton (3). Opener makes the step bid to ask. Responder makes the cheapest bid to show length in the lower suit and the second cheapest suit to show length in the higher ranking suit.
