What Would You Discard? #4996710 (2-shanten)
Which tile do you discard? (maximize acceptance)
Show answer
東 ・ acceptance 40tiles: 5筒 6筒 7筒 8筒 9筒 3索 4索 5索 6索 7索 8索 9索
Why this move works
The answer is 東 (East). The isolated honor is useless, and discarding it keeps the widest acceptance — 40 tiles (still 2-shanten).
Discarding 9s drops acceptance to 36. Far from a win at 2-shanten, you first clear the dead tile to broaden acceptance.
