Hi! One of the newer additions to the laws (I think from Bali 2013) is the following part from the brown sticker policy: f) For the avoidance of doubt an opening bid of one club which may be made on a doubleton or singleton club and which is ostensibly natural and non-forcing should be regarded as natural and not artificial.. I found that it actually makes everything way more confusing for me so I just wanted to clarify a few things: 1. What does "ostensibly natural" mean here? I've seen some regulations that consider 2+ clubs natural if it's specifically with 4-4-3-2 shape but here if it could also be with a singleton club, it seems that all 'clubs or balanced' systems should be treated as natural too? 2. I play fantunes so my 1C opening is clubs or balanced promising at least two but the difference is that it is forcing. Does the fact that we open some stronger balanced hands with 1C make it artificial? 3. If, hypothetically, a precision pair decided to switch the meanings of 1C and 1D and then decided to play 2D as showing diamonds so that the 1C would now become nebolous club promising at least a singleton club, would my precision nebulous diamond defense containing multi now be brown sticker, even though opponents are still playing essentially the same system? Thank you :)
