I would like to know what
2-way new minor forcing over 1N rebid
means. Perhaps it should be rephrased to
2-way check back Stayman over 1N rebid?
The wording as it is now does not make sense to me.

Hi roland,
Reading the notes on BBO advanced, I take this to be the "xyz Convention", where 2
♣ forces opener to bid 2
♦ either as a signoff in
♦ or some kind of game invite. And where 2
♦ is game force. But what is there, is what came from the online description of BBO Advanced, and I have been known to mis-intepret. We will surely see what the panel thinks on this quiz.
New minor forcing is pretty simple... Its also most emphatically does not include a puppet from 2
♣ to 2
♦.
Lets assume an auction like
1
♦ - 1
♠
1N
A 2
♣ checkback bid asks partner to describe his hand further. Partner should show (in order of priority)
1. A 4 card Hearts suit
2. 3 card support for Spades
3. A club stopper for NT
Lacking any of these, partner will rebid 2
♦
2-way checkback uses both 2
♣ and 2
♦ as checkback bids.
2
♦ promises game forcing values
2
♣ shows game invitational values
That is what regular, NMF is. But Ben is absolutely correct on what
2-way NMF is.
Adam and I play 2-way, and not xyz (ie, we only play it on over a 1NT rebid by opener).
Basically, the structure is: (no opps bidding)
1m-1M-1NT-2
♣: forces 2
♦ and...
1m-1M-1NT-2
♣-2
♦
responder can pass 2
♦; or bid 2
♥ to either check for four hearts or three spades (if original 1M=1
♠) or check for three hearts; bid 2
♠ to look for 3 spades, bid 2NT to invite to game (and usually people discuss differences of what it means to bid 2NT directly). Of course, all of these except passing 2
♦ have game invite values.
1m-1M-1NT-2
♦ is game forcing, and opener is expected to either bid a four card heart suit (if 1M=1
♠) and second choice to show three card support for partner's major, and barring either of those being an option, to bid naturally.
Pard opens 1♠, 1N by you, 2♥ by pard.
