| Family | Nactation | Traditional Notation | Note |
|---|---|---|---|
| Slot | $ | bar/20, 6/5 | $ (Slot) is a style family. The non-slotting portion of a roll, if any, usually must be played down (i.e., to or within the outer board). An exception is made for forced moves, or when entering from the bar. |
| Both | B | bar/20, 9/8 | B (Both) is an areal family. On a roll of a non-doublet, one checker moves on the far side of the board, while the other is played entirely within the outer board. |
| Cross | C | bar/24, 9/3 | C (Cross) is an areal family. Half the roll is played on the far side of the board, with the other half jumping over the bar, from the outer board into the inner board. |
| Down | D | bar/20, 9/8 | D (Down) is an areal family. All parts of a roll are played to or within the outer board. As with most families, an exception is made when part of a roll is forced, or is used entering from the bar. |
| Down | d | bar/24, 13/8 | By the 6pt Convention, a spare destination on the far side of the board is preferred when it is closest to the 6pt. Entering on the 24pt, therefore, ranks below entering on the 20pt. |
| Each | E | bar/24, 6/5 | E (Each) is an areal family. Half the roll is moved on the far side of the board, while the other half is played entirely within the inner board. |
| Split | S | bar/24, 13/8 | S (Split) is an areal family. On a roll of a non-doublet, the larger die is played to a destinatinon on the far side of the board, while the other is is played down, i.e., to a destination to or within the outer board. By the Convenience Clause, when the S (Split) family is empty, as it is in this case, S can be used instead of Z. |
| Up | U | bar/20, 24/23 | U (Up) is an areal family. All parts of a roll are played to destinations between the 24pt and 18pt. |
| Wild | W | bar/20, 6/5 | W (Wild) is a style family. It describes a move that both splits and slots (a.k.a. “splot”). |
| Reverse split | Z | bar/24, 13/8 | Z (Reverse split) is an areal family. On a roll of a non-doublet, the smaller die is played to a destinatinon on the far side of the board, while the other is is played down, i.e., to a destination to or within the outer board. By the Convenience Clause, when the Z family is empty, S (Split) is preferred in most contexts. |
| This third-roll position is itself a close decision. What would you play? Why?
Timothy’s selection of the D (Down) family to describe his play of d (down) = bar/24 13/8 is perfectly correct. What he failed to notice, however, is that the capital letter goes to D (Down) = bar/20 9/8. Mike |
