What Would You Discard? #4996709 (2-shanten)
Which tile do you discard? (maximize acceptance)
Show answer
白 ・ acceptance 50tiles: 1萬 2萬 3萬 4萬 5萬 6萬 7萬 8萬 9萬 1索 2索 3索 4索 5索 9索
Why this move works
The answer is 白 (White dragon). Discarding the isolated honor keeps you at 2-shanten with the widest acceptance, 50 tiles.
Discarding 7m drops acceptance to 44. Clearing the honor that does not connect to your hand, to keep acceptance maximal, is the basic 2-shanten idea.
