This is based on this article by david_c david's article
Opening structure:
1S - 4+♠ 11-15 (could be canape)
1H - 12-18 (this one still open see thoughts at the end
1NT -12 14
1D - 12-GF- 4+ ♦ unbalanced
1C - 15+ bal or clubs ,19+ with hearts or 16+ with spades or GF with diamonds
2 level see at the end
david_c claimed that these different ranges for types of hands in the 1C openeing will cause problems constructing a system that works over 1C.
I think this works pretty naturaly.
1C-1D width range of weak (not transfers like in milnium)
1H - 18 bal or 19+ any hand
1S=16-19 with 5♠
1NT=15-17 bal
2C - 15-18 5+ clubs
2D - any GF like in polish
continuations over 1H relay are known from many system.
The seonnd intersting point of this structure is the 4CM 1♠ opening.
i wont get into it now, but i its based on my thory that
1. Spades are less important to distinguege between 4 and 5 cards.
2. Its good to open 1S often.
I also consider killing the precision 2C sending the good 6 cards to open 3C, and the bad 6 cards to open 1nt. This leaves me with hearts and clubs.
This could leave the 2 level for my heart toy, which is another part of that thory
to open weak unbalance hearts hands at the 2 level.
I plan to use 2C/2D to show hearts and minor around 8-12 hcp,what i didnt decide is the shape whater it should be 5/4 either way or 4+4+ or always 5m-4H or always 5H-4m.
Any thoughts are welcome.
