1C - dbl - 1S while playing transfers

[fromageGB]

Does nobody think it's a good idea to have a way to show both majors immediately? If we have to transfer to hearts with those hands, opps will find their diamond fit before we find our spades fit.

Certainly, but I can't do it with a weak 44xx *. My 1NT shows a weak 54xx or 45xx, and without competition opener plays it in his 4 card or responder's 5 card suit, but after their 2♣ or 2♦ at least opener has a chance. We also play 2♣ as invitational or better with 44xx, as it is important to convey both strength and lengths for when they intervene (a double of 2♦ is for penalty) and play 2♦ by responder as 55xx any strength.

 

I agree with you that showing both majors immediately is important. The other hands not covered are 45xx or 54xx invitational or better, and by showing the 5 card suit initially, and the other later (perhaps after interference), opener knows both exact length and strength.

 

Edit : "weak" being defined as "less than invitational".

* Perhaps I should change this so that after 1C (X) the 1NT shows weak both majors unspecified (ie {44} or {54}.)

Yes. The double gives you one extra call so you can show one hand-type more than you could otherwise. Does nobody think it's a good idea to have a way to show both majors immediately? If we have to transfer to hearts with those hands, opps will find their diamond fit before we find our spades fit.

 

In my second scheme, you have all 4 suits covered, so 1NT is free for 45M nf and 2♣ for 54M nf if you wanted.

I don't think this has been covered but what did the double of 1♣ mean?

if it was Mathe it would be for the majors

I suppose some could double for ♣

or just general values

Crash would be 2 suits of same color

 

and does the meaning make difference to your methods?

If you are quoting this figure to a precision of 1 decimal place, presumably you need to have more than a 1000 samples generated?

 

I am no statistician, but I would guess that "all hands, ever" is at least as good a sample as 1000 hands.
