3S forcing 3NT

Is it legal to play something like this by agreement
2NT (20-22) 3NT (slam try both minors)
4C 4NT (100% sign off)

Maybe the problem is that 4NT means "oops I forgot, I meant 3NT as to play!" ?

If that is your agreement about 4NT then 3NT should be more accurately described as "slam try both minors OR to play 4NT (for whatever reason)".
I am not sure that having such an agreement will necessarily save you from the constraints of having forgotten that 3NT was artificial and the UI when it is alerted.

This surprises me. If the auction happened behind screens, I'd say it's roughly 100% that you'd realise what had happened when partner bid 4C. Are you really supposed to proceed under the assumption that partner has a 2236 19-count or similar? Or that partner has found another ace and is making a slam-try?

Question along these lines (brought up by Justin Lall in a similar thread): suppose our agreements are that over 1NT, 2♦, 2♥ and 2♠ are natural and non-forcing. I forget this agreement and think we are playing transfers. I pick up a hand with five hearts. Partner opens 1NT, I bid 2♦, and partner passes. Shouldn't my first thought be "Oh, that idiot psyched a 1NT bid with long diamonds", not "Of course, I've forgotten the system"?
In this auction maybe it's impossible to believe partner has psyched (he wouldn't run until he was doubled). But how far do we take the 'behind screens' thing? What if partner says "3NT is to play" and then bids 4♣?
I guess my point is that I think catering to psyches should be mandated before 'waking up'. The last time partner had a misunderstanding and I thought it was clear from the auction at about the 4-level I drove him all the way to 7♠x anyway. At teams. Solves the misunderstanding problem pretty quick, if not the partnership harmony problem.

You shouldn't think that way since if partner made that comment it would also be UI that you would have to ignore. "Behind screens" is the perfect analogy, since it describes what you would think if you heard nothing.

I don't know where you play, but where I play and have played real psyches are between extremely rare and non-existent.
I have played with one partner for seven years. In these seven years he has never, ever psyched. There have been occasions where he has forgotten a convention. There have been occasions (but much less
![:)](http://www.bridgebase.com/forums/public/style_emoticons/default/smile.gif)
Why should I assume a scenario where partner psyched when I know that this scenario is unrealistic? If we would not have alerts and explanations, I would definitely conclude we have a misunderstanding rather than a psyche.
So, my order of priorities is:
Could this strange bid possibly have any meaning that is consistent with the start of the auction?
If so, I will assume partner meant to convey that meaning.
If not, then we have a misunderstanding. Psyches are not in my field of view.

I don't think that way. I try to handle these things as if it were behind screens, but if I perceive I have more than one logical alternative to a call I err heavily on the side of making sure my side gets a ridiculously bad result, because I think that is the most positive EV in the long run with respect to 'number of times my partnerships forget their conventions', and I think when we forget our conventions we should be punished. The game is not fun if you ever have to think to yourself "We have an agreement, but I have forgotten / don't remember what it is", and it's not fun when your opponents have this happen.
I don't see why we would allow anyone to wake up in an auction that could be a psych as long as there is a nonzero percent chance his or her partner has psyched.
To anyone who says "My partner never psyches, he/she has promised me he won't, etc:" I have it from Mike Flader that that is not a legal agreement or discussion, just like you can't promise you won't psych against beginners.
For full disclosure on my part: the number of times my partners have psyched in the last, oh, 300 sessions I've played: 0.
(Edit: ACBL-land, not sure about other jurisdictions obviously).
(Second edit: read this before your post Rik; no aggression intended towards you and your partner, I'm just trying to play a hard line on this because I'm curious).

and partner opens 1NT (15-17), you bid 2♦ (forgetting it is natural), partner passes it, and the opponents come into the auction in spades, I think you should feel ethically compelled to consider sacrificing - and possibly elect to do so, especially if you think it is worse than sitting - over basically any number of spades they bid. After all, partner doesn't have a 15-17 NT, he has a hand that was willing to play 2♦ opposite an unlimited hand. Whether partner has ever psyched before or not, surely it's not 100% that this is NOT a time he has chosen to do so.

That is obviously untrue, whether or not Mike Flader says it is, any more than if your partner has promised they won't open a weak two bid with a side four-card major. I mean I'm just loling at that statement, sorry. It's like saying you can't agree to always have your bid.
As for the rest of what you say, only if killing yourself in the auction is logical alternative suggested by the UI, or something close to that. LOGICAL alternative, not BARELY CONCEIVABLE WITHIN THE REALM OF THE UNIVERSE alternative.

I'll try to put what I'm saying on more personal and less argumentative terms: if I sit down with Stolid McNeverpsyches, who always has his bid, and I'm in an auction where it's totally obvious that either one of us has forgotten our agreements or Stolid has psyched, and I think that assuming he has psyched will get me a worse score, I am going to assume it. And if that gets me a better score and gets adjusted, I'm not going to argue with it. I wouldn't fault anyone for taking a less hard line, the reason I take it is precisely because the ACBL won't discuss anything of this except to say "Oh, no, you can't talk about these things with anyone!" Bull - I try to play ethically at all times, and sometimes that includes taking into account the possibility that partner doesn't in fact have his bid.

I'm pretty sure I wrote 'logical', not something in all caps, but I can check...
Edit: although my partners probably would say I am on another planet, so the wording is apt

Have a secret agreement that over a cue of 4M partner will now bid RKCB ...
Option 2:
Describe 3NT as either both minors or a balanced 4-10
Option 3:
Give up playing 3NT for the minors

Likewise, some auctions are surely more accident or forget prone than others. 2N p 3N artificial is a good example.

This is different from the situation where you make a bid 3NT which is systemically natural, and partner makes a non-systemic alert before bidding 4♣.

Arguably that's against the rules of most jurisdictions. In the ACBL, for example, you're "expected to play each hand to win at all times".

Not true. Pard/spouse and I have clear agreements regarding psyches:
1--We probably won't recognize it when partner does it.
2--We don't like to do it very much.
3--When we do, it will backfire.
