Alerting - Kokish/2C ACBL
#1

Playing the Kokish responses to 2C, obviously the 2H and 2S puppet sequences should be alerted.
Should openers nt responses showing a specific 2 point nt range be alerted?
2C 2D
2N (22-23)
2C 2D
2H 2S
2N (23-24)
and so on.

I think even this is more than the ACBL Alert requirements are, but I think it's correct Actively Ethical bridge.

My guess would be that 2♥ should be alerted as 'either ♥ or NT.' The response of 2♠ should be alerted as 'asks opener to describe his hand.'

Awfully hard to figure out what you mean here. In your first sentence, do you mean a 2♠ rebid by opener? In your second, are you referring to an auction started 2♣-2NT? In your third, is it 2♣-2♦-2♥? And finally 2♠ is responder's second bid after 2♣-2♦-2♥?
In that last case, if that is what you meant, I disagree. It doesn't ask anything. Opener instructed responder to bid 2♠; he's just complying with the instruction (IOW 2♥ is a puppet bid).

The question was about whether to alert opener's 2NT rebid, because its range depends on whether he bid it immediately or went through the 2♥ Kokish sequence. Everyone knows that you should alert opener's 2♥ rebid, since it doesn't necessarily show hearts. And responder's 2♠ bid after this should be alerted because it's forced, and says nothing about whether he has spades.

Is it? My understanding of the full method is that 2♥ is a marionette rather than a puppet and that Responder can rebid something other than 2♠ with specific hand types. Naturally many pairs play a reduce form where 2♠ really is forced but I am not sure if that is the case here.
Like Ed, I do not really understand the first like of GHSteele's post and disagree with the second - explanations of bids should describe what they show and if 2♠ is forced then it is not asking anything. If 2♠ is not forced then it simply denies any of the hand types that would break the marionette.

But 2♠ says nothing about spades whether there are other possible bids or not. I don't understand how this could not be alertable.
I also think that major-suit negatives, as mentioned above, should be alerted.

It is clearly alertable in pretty much every jurisdiction, the question is over how it is subsequently described. The post to which I was referring suggested the correct explanation is "asks opener to describe his hand".

Well, other bids might show eg desire to play in a minor at the 3-level opposite 20-21, but every bid denies certain hands. 2♠ is the most common bid, and asks partner to distinguish between ♥ and balanced. For me, the followups are 2NT(20-21(22)), 3NT(25+), 3♥(natural) and 3 other(second suit with hearts). So asking opener yo describe his hand is probably accurate IF opponents know that 2♥ was ♥ or balanced.

I must admit that this is the first I've heard of some "full method" wherein 2♠ is a marionette. I used "puppet" deliberately because afaik the bid is not a marionette.

weak distributional hands are supposed to break. 2NT = very weak both minors, 3m = very weak to play

Does that mean that it has some strings attached? Those should be revealed on the basis of full disclosure.

So, "forces" 2♠. Yes, that probably should be revealed, but since my explanation shouldn't mention responses anyway...

(sorry, perhaps the question was rhetorical)
In my experience "Lebensohl" or "forces/asks me to bid 3♣".
When I last said something like "asks me to bid 3♣: usually a weak hand, to play at the 3-level, but can be some awkward game-forcing hands", my partner was surprised.

Also in my experience, "forces me to bid 3♣." That explanation is so totally horrible as to defy comment, but they do it. And then the TD is called when dummy domes down with 4=3=4=2 10 count, and the club lead would set it (and the heart lead doesn't), but "he said he had clubs!" (never mind the "stayman with a heart stopper" explanation after - you just can't get the "transfer" explanation out of their heads).
It's actually relatively trivial (over 1NT) to enumerate the hands, so I do. But I realize I don't think like many bridge players.

Well, if you say "no", you will get something and can ask supplemental questions. I always say "no".

Where is the part about bypassing 3♣ if you have an unusual hand for your previous action? That's the parallel I was making with the Kokish 2♠ bid.

Should I be describing my responses?
Usually I have no agreement beyond "Lebensohl" and "slow denies" and have no agreement about why/how we would by-pass 3♣.
