Mixed Double Chow

What Is Mixed Double Chow

Mixed Double Chow in Chinese Mahjong is a straightforward 1-fan pattern achieved by having two identical three-tile sequences, each in a different suit. It often appears naturally in hands that incorporate multiple suits and multiple chows. While it provides only a small scoring boost, it can blend nicely into broader chow-based or multi-suit strategies. As always, keep your hand flexible, stay aware of tile flow, and be ready to pivot to better scoring opportunities if the situation calls for it.

The Tile Pattern of Mixed Double Chow

• Each chow is a sequence of three consecutive tiles (1-2-3, 2-3-4, …, 7-8-9) in one of the three suits (Dots, Bams, Craks).
• They must share the exact same consecutive ranks but must not be in the same suit.

Example: 4-5-6 in Bams + 4-5-6 in Craks.

Multiple Mixed Double Chows: If you have more than one pair of chows meeting the above condition, you might be able to claim this pattern multiple times, depending on specific tournament rules for repeated patterns.

Fan Value of Mixed Double Chow

Under Chinese Mahjong scoring, Mixed Double Chow is worth 1 fan. If you have exactly one instance of it in your final hand, you add +1 fan to your final score calculation. If you have multiple valid instances, your total could be increased by multiple fans—subject to any limits on repeated patterns in your specific ruleset.

Strategies and Considerations of Mixed Double Chow

Multi-Suit Chows: If you are naturally drawing or melding sequences across different suits, pay attention to opportunities to create the same consecutive rank.

Stay Flexible: Mixed Double Chow requires two suits. If your tiles flow better toward a single suit, you might consider going for Pure Double Chow instead, or you may pivot to a bigger pattern, such as a Half Flush if the tiles align.

Caution: Mixed Double Chow is relatively easy to form, so don’t force it at the expense of chasing more valuable patterns. In multi-suit approaches, watch out for discards or exposures that might clue opponents into your suits and sequences.
