[blml] What does "specified" mean in Law 29C?

[Guthrie]

[Ed Reppert]
Any forcing call is, by the definition of "forcing" not an offer to
play in the denomination named or last named. Not all forcing bids are 
artificial, though, so "forcing" and  "artificial" are not synonyms.
A call cannot be both artificial and not artificial. Can it be 
neither? A call cannot be both natural and not natural. Can it be 
neither? Can a call be both natural and artificial?

IMO ...
- All calls are natural *or* artificial but *not both*.
- All artificial calls are conventiona1.
- Most but not all natural calls are conventional (e.g forcing natural 
bids are conventional; a bid that shows exactly six of the bid suit is 
conventional)
