I almost posted earlier... a post in which I almost agreed with Ken in terms of one of his comments
In terms of who was to blame, it was North for that 4N call... but it is a question of style, and if N expected a sound opener, then it was either nobody's fault or shared.
For me, assuming that 2
♣ was acceptable, and I will return to this later, the auction then goes 2
♦ 2
♥, and we come to another fork in the road.
Those who use 2
♥ as setting trump, and I think Ken is in this group, should see the auction, in my view, as going 4
♥ all pass: 4
♥ is a slow-down bid. It is the call one makes with a bad hand... not merely 'nothing special', but a bad hand in context, and despite the Qx of
♣, this hand has NO interest in slam unless partner has a monster, and that's what 4
♥ says. This is where I almost agree with Ken... but I don't use rules such as what my response to keycard would be. I suspect, however, that he and I would bid 4
♥ mostly on the same hands, rule or judgement.
As for me, I don't like 2
♥ setting trump. I don't merely 'occasionally' give perference: I frequently give preference. For me, will prefer back to 2
♥ unless I have a better call.
Give me xxx Ax KQx AJxxx, and this is an automatic 2
♥, and, frankly, I don't understand any other call, with the exception of perhaps a stall of 2
♠.
So for me, opener has an easy 3
♦ rebid over 2
♥, patterning out, with no suggestion of extra values (nor any denial of them). Responder confirms real hearts via 3
♥ and now opener makes the weakness bid of 4
♥.
It is critical for the partnership to understand what opener's cuebids (or 3N) mean after 3
♥. If you play that opener needs extras to cue below game, then you are in trouble with this kind of fit. If, however, you use the first cuebid to announce that you are not ashamed of your hand and are prepared either to drive the hand or to cooperate, then 4
♥ sends a powerful message.
So switch to responder. The key is the xxx in hearts. It is IMPOSSIBLE to construct a 5-5 red hand where slam is playable and opener bid 4
♥. You NEED a minimum of AKQxx Axxxx... .and no bridge player with a pulse would bid 4
♥ on that, opposite a (mild) slam try 3
♥ bid.
Now back to the debate over 2
♣ or 1
♠.
I see the idea behind 2
♣, and we recently had a thread devoted to it, altho, if I recall, the hand that triggered the discussion was 4=4 in the blacks. This 4=3 blacks is an extension.
At that time I observed that I had for years played, in one partnership, 2
♣ as an artificial gf, and that worked very well.. but it is far too complex for any but the most dedicated partnership... it was a relay method.
The problem with std, as has been pointed out, is the need to bid 3
♣ FSF, which leads, often, to problems. What if opener bids 3N?
And what if opener is a minimum 2=5=4=2 with bad hearts and no spade stopper? What does he bid...3
♦ or 3
♥?
And so on.
And, as Ken pointed out, there would appear to be no easy way to 'improve' our auctions over 1
♥ 1
♠ 2
♦. We could use 2N as a forcing bid, on the basis that it will be rare that we ever want to play exactly 2N, but then what do we do with 10 or 11 count 4-1-3-5 hands over 2
♦?
So there are obvious merits to 2
♣.
The downside is that use of 2
♣ in this fashion would appear to result in the assumption of captaincy by responder in all auctions, while many, many constructive auctions benefit from NO captaincy in the early stages. 2
♣ as artificial essentially robs opener of the ability to exercise judgement on many hands.
Furthermore, it is not exactly a panacea.
Let's look at opener with 2=5=2=4. xx QJxxx Kx AJxx
What is he to bid over 2
♣?
He can't make the natural, descriptive call of 3
♣.. .or, more accurately, if he does, the partnership is at the 3-level with neither side having exchanged much information, while the staid traditionalists have bid 1
♥ 1
♠ 2
♣.
Which side is further ahead?
And if we don't allow opener to raise 2
♣ to 3
♣ without 5 cards or (a more likely limit) values for a high-level reverse, we are forcing opener to rebid a bad 5 card heart suit, and the auction will almost certainly thereafter be far more opaque than had we permitted responder to bid 1
♠.
So I fear that, as so often happens, those espousing a new treatment have focussed on the hands on which the treatment works, and have (so far in this and the earlier thread) ignored those on which the traditional approach is better.
Obviously, the question of whether the artificial 2
♣ is superior DESPITE the problems I have just identified is open to debate... but I am not convinced by arguments setting out the weaknesses of the traditional approach and the benefits of the newer... as if the newer had no flaws.
