How Pure Double Chow (一般高) works
Two identical chows — the same three consecutive numbers in the same suit (for example two runs of 3-4-5 dots).
Two of the hand's runs are exact duplicates, matching in both suit and numbers. This differs from a mixed double chow, where the two runs share numbers but come from different suits. It is a small fan that often combines with other run-based patterns in the same hand.
Good to know
- •The two chows must match in both suit and number sequence.
- •Same numbers across different suits would instead be a mixed double chow.
- •Two separate identical-chow pairs in one hand can each contribute this fan.
