This blog provides supplementary thoughts and ideas to the www.bridgematters.com site.

Today we try a blog posting written in the new google Chrome browser, and we continue with system frameworks you haven't seen before:

14-18 1M with 10-13 1D

1C: Either 
a) 14+ with 5+ minor, no 4cM, unbalanced
b) 19+ any

1D: 11-13 balanced (can have a 5cM, even a 5-4-2-2 with a 4 card minor), or 10-13 unbalanced without a five card or longer major

1M: 14-18, 4+ major, if balanced 16-18

1NT: 14-16 balanced, no 4cM if 16

2C: 10-13, 5-4/4-5+ in majors

2D: 17-18 balanced, no 4cM

2M: (8-9)10-13, 5+ major, if just 5 must have singleton and not 4+ in other major

2NT: 10-13, 6-5/5-6+ in majors

In this system, 1D makes up for a mix of hand types by having a small range of values.  The 2D opening has responder well placed to judge the hand, whether or not the opponents enter the bidding.

1C as Cs or 19+ or almost either

1C: Cs or Big, either 
a) 5+Cs unbalanced, no 4cM, 10+
b) 5+Cs unbalanced with a 4cM or 4-4-1-4 exactly, 10-13
c) 19+ any
d) 17-18 balanced, no 4cM, 4+Cs or 3-3-4-3 exactly.

1D: 2+Ds, either
a) 11-13 balanced (can have a 5cM, even a 5-4-2-2 with a 4 card minor)
b) 5+Ds unbalanced, no 4cM, 10-15
c) 5+Ds unbalanced with a 4cM or any 4-4-4-1 with 4Ds, 10-13

1M: 14-18, 4+ major, if balanced 16-18

1NT: 14-16 balanced, no 4cM if 16

2C: 10-13, 5-4/4-5+ in majors

2D: Either
a) 17-18 balanced with 5/6Ds, no 4cM
b) 16-18 with 5+Ds, unbalanced, no 4cM

2M: (8-9)10-13, 5+ major, if just 5 must have singleton and not 4+ in other major

2NT: 10-13, 6-5/5-6+ in majors

The 2D opening has responder super well placed to judge the hand, and responder can pass 2D with a bust.  The 1C opening spans from 10+, but the 14-16 range is isolated to 5+Cs unbalanced with no 4cM, and responder will be able to consider the 1C opener mostly in the 10-13 or 17+ range.  15s with 6+Ds should upgrade into the 2D opening, keeping 1D limited.  This is a system that will win team matches against top opponents when the hands fit the methods.
