Doublet Replies: Rules for beginners

In Response To: Non-doublet Replies: Rules for beginners (Axel Reichert)

For beginner doublets, I've resisted the temptation to use Nactation and tolerated traditional. However, it seems to me that destination-only suffices, and for two checkers it can be done either with (for example) "5(2)" or "5pt" (the latter saves a character and it's easier to read).

43S-11N is -.0419, but I've left it in for now. (I suppose that means the current doublets threshold is .042, though its still .06-ish for the full set including non-doublets.) If you want that thorn removed, you can add "or 43S" at the end of 11a.

I found your double 4s rules hard to follow.

I prefer listing the candidate plays in order of hierarchy, rather than the plurality play (with no "a" or "b") followed by exceptions.

Does the following rule set work? (Point-On-Head or * is a must-hit, otherwise hit is incidental.)


Replies with no blunders (< .06)

Doublets

11..(a) 4pt* vs 3-split, or 22 5pt vs low split
......(b) 7pt 5pt

22..(a) 4pt: + 20* else 11pt

33..(a) POH: 7pt or 5pt 3pt
......(b) 21pt 10pt

44..(a) 5pt* or 20pt 4pt*
......(b) 16*: + POH else 9pt
......(c) 20pt 9pt, if blocked then 5pt

55..(a) 3pt, + 1pt* if poss.

66..(a) 18pt 7pt ....


Below is what it looks like if "pt" is replaced "p" in each case, and the space between two-point plays is removed. I slightly prefer this. (It doesn't work well if you keep the "t" because it is too tall a letter, making the second of the two numbers less legible.)
