The case that I was referring to was the one involving one of the Dutch Pairs playing in one of the big WBF events a couple years back.
As I recall, they were playing a canape overstructure over short club openings.
The Dutch claimed that they were playing a conventional defense to the opponents conventional opening.
There was a counter claim that
1. A 1♣ opening that shows either clubs or a balanced hand is natural
2. The Dutch were using a Brown Sticker Convention without appropriate disclosure.
I think that they might have also run afoul of a restriction on the total number of BSCs that they were allowed to use.
I was rather shocked when John Wignall ruled that the 1♣ opening was, indeed, natural...
Seem to recall that you were involved in that case in some way
Ah, that - sorry I didn't understand your reference. I may be remembering wrong, but I think that:
The structure the Dutch were playing over any 1 club opening wasn't anything as benign as canape overcalls. I don't remember the whole thing, and haven't seen it recently, presumably because it really doesn't work well when the opening bid can be essentially natural, but I know it included jump overcalls that might or might not have length in the suit named and simple overcalls that showed extremely varied hand patterns and values. The bids were clearly brown sticker, and the argument about whether there were too many of them had to do with counting - if you play a method where 1
♦ shows either diamonds or hearts or clubs (I'm just making this up) and 1
♥ shows either spades or diamonds or hearts and 1
♠ shows either spades or clubs or diamonds, all of them with less than 8 HCPs, are you using one BS method or 3? One of the 2 pairs playing the method had described the method as one BS bid (and 2
♥ or 3
♥ showing length in either hearts or spades as a second BS bid) and therefore claimed that their opponents didn't have seating rights under the rule about 3 or more BS bids. Their teammates had described the same thing as multiple bids. I think that this was a situation where our position (you're playing more than 2 BS bids) was clearly correct.
The question about whether a 2+ club that is 2 only with a balanced hand should be defined as "natural" or "conventional" is of course far less clear. That was relevant to whether the Dutch methods were allowed in the Round Robin. For Shanghai, the ruling was that such a 1
♣ bid was to be treated as natural, so BS methods were not allowed over it in the Round Robin. I believe that ruling has subsequently been changed for WBF events.
