Open ThorvaldAagaard opened 4 weeks ago
The problem seeems solved with 8128 On table 2 the bidding seems wrong. 3c is not natural but pass or correct. The correct bidding is 2nt followed by 3h 2s p 2nt p 3d (spades + diampnds) p 3h - natural, forcing
I did not find a description of responses in polish club but in the description of Muiderberg: https://en.wikipedia.org/wiki/Muiderberg_convention
The partner of the Muiderberg opener can take the following actions:
pass (with tolerance for the opened suit) bid 3♣ (a pass-or-correct bid) bid 3♦ to invite for game in the major suit bid 2♠ (over 2♥) as a contract improvement (opener is allowed to raise with a suitable hand) bid 3♥/♠ (opener's suit) as a preemptive raise bid 3♠/♥ (other major) which is non-forcing but invitational ask for the minor suit using a 2NT relay bid with a strong hand.
Next BBA I'll think about Muiderberg later.
Still looks wrong

2N is a natural descriptive bid
