Nactation Questions — Clarifying Parts of Hit/Most/Six

Posted By: Taper_Mike

Hit Convention

The Hit Convention is the first part of the Hit/Most/Six Rule. In ranking the plays in a Nactation family, the Hit Convention assigns a higher rank to hitting plays than non-hitting plays.

Some questions:

  1. Is hitting a qualitative or quantitative issue? Does a play that hits twice, for instance, rank higher in a Nactation family than a play that hits only once?
  2. The H (Hit) family includes in its definition a preference to hit on the highest point possible. Does the Hit Convention include a similar preference?
  3. If the answer to question 2 is, "Yes," does that mean that the preference to hit on the highest point possible has been removed from the definition of H (Hit)?
  4. While we're on the subject, does the K (Kill) family also include in its definition a preference to hit on the highest point possible? After the first hit in a K (Kill) play has already been selected, should the second hit in a K (Kill) play then hit on the highest point still remaining given the fact of the first hit? Obviously, this is pretty abstruse stuff. Your opponent will have to leave a bunch of blots around before any of it kicks in.

Most Points Convention

The Most Points Convention is the second part of the Hit/Most/Six Rule. The Most Points Convention ranks the plays in a Nactation family according to the number of points that they make or retain.

An easy question:

  1. For purposes of the Most Points Convention, does the location of an owned point matter? By the Most Points Convention, for instance, does owning the 5pt outrank owning the 24pt? Let me make clear that I understand that the 6pt Convention does include a provision for ranking plays according to the location of an owned point. I am not asking about that.

6pt Convention

The 6pt Convention is the third part of the Hit/Most/Six Rule. It has two parts: the Owned Points Convention is applied first, and the Blots and Spares Convention, second.

These question pertain only to the Owned Points Convention.

  1. Does the following describe the proper procedure when comparing two plays under the Owned Points Convention? Begin at the 6pt, and search outwards in both directions one point at a time until you find a point that is made in one position and not in the other. The position in which the point is made outranks the other.
  2. What about ties which pit ownership of an inner-board point against ownership of an outer-board point? Does owning the 5pt, for instance, rank higher than owning the 7pt?

In the position below, the two best plays in the N (Near) family are 10/8 6/5 and 8/7 6/4. Both move one checker down and one checker inside. Both make two new points. Because no other play hits or makes two points, these two plays will be ranked first and second in the N (Near) family. But which should get top billing? Can the issue be decided on the basis of the locations of owned points? Or is it a tie by that measure, with the owned 5pt in one play matching the owned 7pt in the other? If it is a tie, of course, then the issue will have to be resolved by checking the locations of blots and spares.

Thanks once again for taking the time to explain these issues.
