WJ2000 1♦ is usually 5+, except 4 in any 4441 or with exactly 5♣ 11-14.

 

WJ2005 1♦ is 4+.

 

People here(*) uses 2♣ natural, 2♦ majors often.

I never thought about much changes on strong !c openings, except bidding more aggressively.

 

But somebody pointed out 1NT could get free for any other purpose.

So quickly thinking on it, might be good to overcall with transfers starting from 1NT ?

You could this way also cover 2-suiters and get stong opponent on lead.

I believe transfers have some merit. I would however do it in quite another way:

 

Pass: Weak or 15+Bal.

X = Transfer to diamonds.

1♦ = Transfer to hearts.

1♥ = Transfer to spades.

1♠ = Transfer to clubs.

 

Edit: Naturally this wouldn't apply to openings in fourth hand.

 

This would cover all constructive hands.

 

1NT = Both majors.

2♣+ = Preemptive.

 

As they will quite often have 12-14 bal., this is another possibility:

 

2♣ = "Perfect" takeout double of 1♦, 11-16 non-forcing.

2♦ = "Perfect" takeout double of 1♣, 11-16 non-forcing.

 

I have some experience with these kind of bids, and when you make them, they are quite efficient, especially if you are well-organized (jump in a new suit preemptive, while better hands "cue" in the opponents alleged suit), putting advancer in an excellent position.

 

The relatively low frequency is somewhat an argument against these bids.

Yes that was my second idea, covering all aspects :

- 1 level : Transfers with at least opening values (and could be played illimited in strength), like you described (X = 1♦)

 

- 2 level : Same intervention scheme as what you play on a strong 1NT opening, but clearly preemptive. With 1NT = the meaning of your X on a strong 1NT.
