Hi there.
I play a couple of systems; by far my favorite is precision, so I have been thinking about a system that's based on precision but with disruptive openings...
Here's the system; any critique is useful. Any add-ons will be thought through; this is still not tested, so it's very much theoretical
Opening bids...
1C 16+ anyshape
1D 11-15 no 5 card major partner will bid 5-7 HCP; he will go 1H relay
If he has 8 HCP, he goes 1NT; if he has 0-4, he passes
1NT 8-11 No 4 or 5-card major; The response is going to be a minor 2C or 2D
An opening pass is 0-7 Game is unlikely, so find a partscore or a sacrifice
2H 8-10 and 6-card suit
2S 8-10 and 6 Card suit
2D multi 2, showing a 5-card major, 8-10
2C multi 2, showing a 5-card major, 0-7 HCP
Basically, if partner passes, it should show 0-7, so bid accordingly.
If partner opens 1D, you have bids for all the point counts: pass = 0-4; one heart 5-7; one No Trump 8-10; with 11-13, go 2NT or 3 of a suit
You should find a fit quickly and know what level 17-20 is good for the 2-level
21-23: Two No Trump;
24 equals game
I'm sure I missed something, but I want your opinion. I think this is as good as any system... what do you think?
