An easy question... or...

Toplevel & screens

---

After 2NT South called for me. Beside the table he told me:

"I made a wrong bid. 2NT is gameforcing but I thought it was limit raise. We changed that recently. Can I change my bid?"

[campboy]

This probably depends on your screen regulations. Without screens the answer is no, of course (25B just tells us how to deal with an irregularity, it doesn't permit it).

[paulg]

Screen regulations vary but none of those that I've seen (EBU, SBU, EBL, WBF, ACBL) would permit a change under these circumstances.

[jallerton]

Was the 2NT bid released on to the tray and released from the hand before the player called the TD? If yes, then the call is made under WBF screen regulations. The screen regulations imply that the call cannot be subsequently changed, but I can't see any specific reference to Law 25B.

Quote

25B. Call Intended

1. A substituted call not permitted by A may be accepted by the offender’s LHO. (It is accepted if LHO calls intentionally over it.) The first call is then withdrawn, the second call stands and the auction continues.

So perhaps Sjoerds is asking: does offender's LHO have the right to accept a change of call?

For what it is worth, under EBU screen regulations, infringing calls "shall not" be accepted (EBU White Book 5.4.1(b)). I think this should apply to accepting a (Law 25B) change of call.

Of course it isn't allowed under the LAW 2007. But if I remember well, it was possible before this time [with all kind of restrictions for partner].

But my problem is where to find it in the Law. 25B says:
A substituted call not permitted by A may be accepted by the offender’s LHO. (It is accepted if LHO calls intentionally over it.) The first call is then withdrawn, the second call stands and the auction continues.

I cannot read the explanation as given by the EBU, etc.

campboy gave me one argument:

I think Campboy has it right - if the player substitutes a call, Law 25 is invoked. We have an official interpretation, I think, or at least "custom and practice" that in a 25A case, calling the director instead of actually making the substitution will still result in the player being allowed to change the call, but that does not apply to a 25B case, so the answer to the question in the OP is no, he cannot change his call. Screen regulations might modify that, I suppose, but as paulg suggests, it seems unlikely they would. What screen regulations are in force in the Netherlands?

As far as I know a translation of the EBU regulations.

The situation actually happened and at that time I was not aware of this interpretation.
The screen mate had no problem with the change and bidding went on without any problems.

I was wondering if this might be an issue in the next edition of the laws. But that's probably an other thread

Do you mean "EBU" (England) or "EBL" (European) ?

EBL ...
