Equally not, but either your are always passing a 6-5 giving opponents space to find their information or you have to open something misdiscribing your hand if you have strict regulations for the bids.
I dislike that there are so many criticizing the system.
Actually they knew a lot and its so narrow, that many had problems to construct different hands, that make a big difference.
Basically both should bid more. North has a great hand with a Diamond shortness and 4 trump at ...
My point was a different one. A 5611-hand can t have a void. I assume with a void we could bid 4♥ or 4♠ right over 3NT.
To me the importance of a hand with exactly 1156 and the bare ace of ♠ is not that great.
Nice to see a deciding 50-50 vote. I had this situation with one of my regular partners and was surprised that we weren t on the same page.
But now I think it was not entirely clear. Who has discussed exactly this situation?
