- Trivial; the single call described a while ago in the Zip Coder (sorry, can't
- remember the author) named; "Go Over There and Turn Around" is
- sufficient to produce ANY position from Any starting position.
- Note that since GOTATA is not on any list, it's point value must be '0'.
- We are, of course allowing all versions of the call, e.g.
- Go over there and don't turn around
- Don't go over there but turn around anyhow
- Don't go over there and don't turn around
- Go over there and turn around [(left|right|in|out|etc),(fraction)]
- (fraction)[left|right|reverse|mirror|nothing](fraction)
- (don't) [(Go Over there) | (Come over Here)] and/but ((fraction)| (don't))
- turn around [right|left|in|out|etc]
-
- e.g.
-
- 3/8 left don't come over here and turn around 1/2 out
-
-
- And the ever-popular "Go over there and sit down"
- The not uncommon "Do your part of GOTATA"
- Random Crazy GOTATA
-
-
- You begin to see the possibilities...
-
- So the answer to your question is that it all (including asymetrics) can be
- done with one call that uses zero points.
-
- Ok, back to work
