All agreements over irregularities are illegal (ACBL)

[barmar]

What you can't do is play steps over sufficient overcalls, natural over insufficient overcalls.

Why not? if you adhere strictly to the comments of the ACBL Director quoted above then this is your only option!

But isn't that a clear example of "varying agreements", which you're not allowed to do?

 

So the regulations say you're not allowed to vary your agreements after an irregularity, and the email says you're not allowed to use any conventions after an irregularity. This implies that you're not allowed to use any conventions at all, because you must ensure that your normal agreements don't vary from what you would do after an irregularity.

 

Since this conclusion is obviously counter to how the game is intended to be played, the premises must be wrong (reductio ad adsurbum).

Or alternately, both rules are in fact rules in the ACBL, and the rules in the ACBL are "counter to how the game is intended to be played". Presumably because not enough time has been spent thinking about their consequences.
