Magister 2C is a Polish version of NMF which applies to auctions such as:

1C-1H; 1S-2C
1C-1H; 1N-2C
1H-1S; 1N-2C

that is when ever responder has shown a major, opener's rebid is consistent with a balanced 12-14, and fewer than 3 suits have been shown (1D-1H; 1S-2C is not Magister, but 4th Suit Forcing).

As part of Magister

• responder's second round jump (1C-1H; 1S-3D) shows 55 and is GF;
  
• responder's simple suit rebid (1C-1H; 1S-2D) is natural and non-forcing;
  
• responder's 2NT follow-up to Magister 2C is forcing (so responder with a 5M4m GF can rebid 2NT and leave it to opener to introduce the 4cm);
  
• responder's new suit after Magister 2C (1C-1H; 1S-2C; 2D-3D) is GF and shows a 4cM and 5+ in the new suit;
  
• but, responder's 3C follow-up to Magister 2C is a club sign-off

From this you may see that it is WJ05 style to respond 1M to 1C with a GF with a 4cM and a longer minor.

Anyway, I'm wondering what responder is supposed to do with 4S and 6C after a start like 1C-1S; 1N?

Havent you already answered this question immediately above?



I think your real question is, what bid with good cards, 6C and 4S.

I think as now it is bidding 3C instead of Magister 2C.




I have a memory such a problem was discussed and dissecred in a lenghy thread several month ago / some year, ago.

Yes, 4cM + 6♣ and a GF is a problem. Also 4cM + 5♣ and 10-12 is a problem.

Yesterday, I held x QJxx ATx Kxxxx and rebid 1N after 1C-1H-1S. Not so bad, but I would not have been so happy if the auction had instead started 1C-1H-1N.

I did not search for any past threads, but will do that now.
