How about: "Our 1NT is 12-14, unless the opps play a double of that as penalty; in which case we play 15-17, unless the opps play a double of that as something other than penalty; in which case it is 14-16."
No you can't play that.
But what about this one:
NS: our 1
♣ opening is natural and forcing, 13+ (Fantunes style).
EW: ok, we play strong pass against that, with 1
♥ as a fert overcall.
NS: ok, in that case our 1
♣ opening is obviously nonforcing.
EW: too late! You are invoking the loop!
Here NS could argue that the description of their 1
♣ opening as 13+ natural is enough. That it is forcing is something that falls under the description of responses (i.e. the description of the response "pass" is "nonexistent"), but they can vary that on the basis of what the intervening pass means. A response is a defense against opener's LHO's pass, and you can play different defenses against that pass depending on what it means.
So I would go with NS here.
The world would be such a happy place, if only everyone played Acol :) --- TramTicket
