If I double, 2N is neither scrambling nor natural. We play Lebensohl.

3. With a stiff I expect pard to bid 3N or 4 with AK of and bid 6 over 3N, 7 over 4. Anything else agrees . I will start cueing and give pard a chance to cue twice. If he does, I bid 7 else 6. 4/N sounds good, but not good enough to change my vote. IMO 3 is better then 2 because now pard can infer that I don't need much to play in and that 3N is not an option.

That could be a good starting point if you don't want to sacrifice 2. The problem with Ron-style is 2-3; 4 (or even worse 2-3N; 4). You are on the 4-level and don't have a fit yet. You don't know if pard has a self-suficient suit or a fit in your secondary 4crd suit. If you bid a new suit is this natural or a supporting cue-bid. Ron-style is very good if opener is balanced or 3-suited and of course if he has a fit. The real benefit is if responder does NOT have a semi-positive. How about 2 semi-positive with a suit and 2N semi-positive balanced? After 2 opener asks for the suit with 2N. In both cases 3 asks controls and 3/M/N(=) shows a self-sufficient suit.

PS: I have played Kaplan-Sheinwold for many years. They use control responses. 1m openings can be very strong and 2 with a minor tends to be one-suited.

PPS: In my Polish Club based system we can differentiate between fit-finding with 4crd M and 5crd M, balanced, one-suiters while still on the 2-level. This 19+ not 23+ however.

Playing a wrong-sided 2N with 18+0 if responder has a balanced bust sounds like fun.

Yes, I like to have a strong 2-opening, even more so because I can then open 1. I never understood 2 waiting. Both Ron's and Kit's (and similar) solutions have their merits, depending upon the type of 2. Ron's method is good with a balanced hand or shapes like 5-4-3-1, where your primary object is fit-finding. Even so, the semi-positives should be strong enough to play 4N, because opener might be forced to introduce his 5crd on the 4-level. Kit's solution is suited for an opener with a self-sufficient suit. Knowing the number of controls immediately gives you a good picture of your safety level. What is the solution if you don't want to play a strong club or polish type system? Use 2 and 2 as strong opening bids for the two types and not for differentiating strength. I haven't worked it out, because I don't need to. Maybe someone insisting upon a “natural” system will.

Great, pray tell how N deduced, that J would be the 12th trick.

The same principles apply in other 3/4SF sequences. In fact in all possible in my system. KISS!

Special sequence: 2 is a marionette. Opener rebids 2 unless (s)he has 5(6)-4 then 2N. After 2 2N shows invite with 5(6)-4. All other bids are FG. With good and bad I would simply bid 3 however.

Until reading Randy's comment, I voted 100% N, but WNT made me go for 100% S. IMO this should have been a victory for WNT. The biggest advantage of WNT is when you DON'T open 1NT! If you play SNT you have to shoot 4 because pard will expect a WNT if you bid 3. If you play WNT pard knows that you have extras in hcp or distribution.

As soon as bridge is accepted as olympic sport cheating will become legal:-(

Try looking at 4SF (and 3SF) from another perspective. Everybody is trying to define openers bids after 4SF. Because bidding space differs with the 4(3)SF-bid openers bids have different meanings in different sequences. Not KISS. Again ask yourself why responder bids 4(3)SF (see my first reply). I suggest that 4(3)SF is a marionette (opener bids next strain with some exceptions) and responder now explains his reason for 4SF. Bidding an already bid suit is natural and slamgoing (#3 of my first reply), 3N denies a stopper in the 4th suit (#2) and repeating 4th suit asks 3crd support (#1). In our system it is possible find out about stoppers and fit below 3N in all cases. I haven't worked it out for a natural system. I guess it will work for all 4SF sequenses, I'm not sure about all 3SF sequences.

There is no such thing as a free lunch. With all 3 examples you would like 4SF to be F1 only. In my proposal (pard didn't agree yet!) 2 shows 8-11 and 5 or a bad 6 (with a good 6 we can bid 3 now or would have bid 2 over 1). With #2 I would bid 3, with #3 2, with #1 my preference is 2.

Volontarily going past 3N (sequence 2) has strong slam implications. By my rule sequence 1 is a slamtry in showing A, K or Q in . If your rule has 4 forcing and setting I would expect a weaker hand with the message slam possible as it seems you have no values opposite my singleton (I would bid 4 with such a hand).

Not legal, some players at one of the clubs I play have a habit of doing this. At a club level I don't care. I'm not even sure if I would protest at a tournament.

It depends upon the rest of your system. Jus ask yourself with what type of hands you would use 4SF (and also 3SF). In my book, there are 3 reasons: 1) 5crds in my M, looking for support, 2) NT-hand, but missing stopper, 3) slamgoing in one of the suits bid. A type 3 hand is obviously FG+. With a type 2 invitational hand, I raise one of pards suit. If a 2M-rebid covers the invitational type 1 hand, 4SF is FG by exclusion (my preference), if not, it should be possible to stop in 2N or 3m (what I currently play).

A jump spends a lot of bidding space and should therefore give a precise picture of your hand. Opposite a limited partner The picture is that there is no slam, if pard is not limited you need to give a describe your hand. In the above examples, I would expect 4M to be a balanced minimum with good trumps and scatterd values outside. If you do not play jumps in a new suit as asking bids splinters would be good companions.

But they represented IBF, not ACBL. IBF is responsible for those who play on their national team.

I didn't mean to criticize Kit either, but IMO we need simpler rules on my level. Going back to the 3-bid in sequence 1. Responder is either looking for a 5-3-fit in or for a -stopper. Opener bids 3. IMO this shows a genuine fit, otherwise (s)he would bid 3N with a stopper or temporize with 3 without. Now what? Responders bids 3N if (s)he obviously does not have 5 (else 4) or a -stopper (else 3N in stead of 3). By this logic 4 (and also 4/) would show a slamgoing hand in .
