Round 1: Direct Special-Hand Path
Hand: AS 9 K 4 7
- Choose base 9 + 4 + 7 = 20, which is valid.
- Point cards become AS + K.
- This satisfies Niu Dong Gu conditions and produces a high-priority outcome.
Takeaway
When AS appears with J/Q/K, first test whether the remaining cards can form a valid base. If yes, that route is often very strong.
