How Two Terminal Chows (老少副) works
Two chows in the same suit, one running 1-2-3 and the other 7-8-9 — the low and high terminal sequences of that suit.
The pattern requires both the 123 and the 789 chow within a single suit, capturing the two terminal-bearing runs. The remaining sets and pair are unrestricted. When this appears across multiple suits or repeats, it can combine with related sequence fan, while staying within its single-suit definition for each occurrence.
Good to know
- •Needs both 123 and 789, and both in the same suit.
