1c/1d in natural systems


Recommended Posts

This post is for the syac and 2/1 players too.

I think anyone who understand bidding should feel unconfortable with the common 1 and 1 opening in 5 card major systems.

Those two bids usually have lots of duplication with each other, they both show a balance hand with no 5 card major, opening and not good for 1nt or 2nt opening.

4432 will open 1d and 4423 will open 1c, but those two hands are almost identical and for practicle bridge they are the same. Not only that, but 1c and 1d got the lowest ranking bids which are the best bids which leave the most free bidding space for invastigate, but most of it is a waste because of this duplication.

This imo is the #1 thing a system designer should aim to change.

I tried many things, ill give here one example in which i tried to change the least of the natural systems, just trying to make something better then normal but not aiming for the best.

Lets call it "The Diamond Spade"

1D = I got 4 card in spade, or a 6 card diamond.

1C = no 5 card major, no 1D opening (can have 4 card spade if the clubs are much better then diamonds)

 

Now comes the question of how many clubs we need for 1c and how many diamonds for 1d.

As i aim only for better and a simple system, ill go with this

open 1D only with 3+ card diamonds, when there are no 3 card diamond ill open 1c even with 4 spade:

4324 will open 1c and show the spade later, the good part about this is that 1 spade bid after a club opening will show a nice club suit (probebly 4+)

Now to 1c, with 3442 i'll be ok with 1c on doublton.

the main problem is with 3452 or 3451, i have few suggestions :

1. open 1c anyway and hope for good

2. open 1c but play 1c as forcing (can only be passed with 3/4 clubs) its not too hard to design a system for this, since 1c is very low.

3. i think this is simplest and maybe best, spare the 2d opening for 5-4 hands, I like this because, 2D opening isnt that much of a use anyway, the bid of 2D with this 54 will have be a very good premptive value.

Thats all for now, i am not getting into the responses structure because its not the point.

The advantage of this are pretty good imo, the 1D bid is your strong bid ofcourse and will win you some competitve bidding, and will also give you some adv on the non competitve bidding. remember you pay nearly nothing for this.

You might consider changing the major suits for this system, calling it "The Diamond Heart" this might be better in competitve since after a natural 1c (1/2/3S) you are in a bidding problem ,yes you play negative doubles but these are far from perfect.

 

I consider this just an example, you are welcome to find better used to those wasted most expensive 1c/1d bids.
