Simple enough question: I play an overcall of 1NT as a light three suited takeout (8-14). What sticker does that make my system?

Is that a brown sticker treatment?

ABF System regulations are here: http://www.abf.com.a...ystemRegs11.pdf

I had just blithely assumed that it was OK because it's like a takeout double, but I may be quite wrong on this.

Over here, it's General Convention Chart, which means it can be played in any game.

It looks like brown sticker unless you have a slightly tighter definition. (1H) 1NT as a three-suited takeout guaranteeing four spades would be ok.

First of all: "brown sticker" never applies to a system, but only to individual treatments. Your system is classified as green, blue, red or yellow, and it may or may not contain brown sticker conventions.

Secondly, a brown sticker can only apply to (a) an opening bid of two clubs through three spades, (b) an overcall of a natural opening bid of one of a suit
or (c) any weak two-suited bid (whether it be an overcall, an opening bid or a response) at the two or three level. A 1NT overcall is obviously none of the above.

The classification of your system as green, blue, red or yellow is based solely on the meanings of your one-level openings, so the use of this 1NT overcall treatment is of no relevance to the system classification; although you would be required to prealert it.

It doesn't fit the definition of a brown sticker convention so you would be free to play it any ABF or WBF event subject to meeting the prevailing disclosure requirements.

No-Trumps is not a "suit" for the purposes of the Brown Sticker definition.

I must be missing something; it looks like b) to me.

Yeah, isn't it an overcall of one of a suit? Though that said.. isn't a takeout double also such a call?

As I was rushing to get the above post out the door it seemed to me to mean that the overcall must be 1♦, 1♥ or 1♠ but that is of course silly. So yes, you are probably right.

[campboy]

Natural NT overcalls are listed as an exception to b) so I infer that artificial NT overcalls are included.

In normal usage, "overcall" means a bid over RHO's bid, despite the name ("overbid" being something else entirely). So a double is not included any more than a pass would be.
