A silent 34-second film. East 1, turn 9: you drew 4s and have to pick a discard. The pro cuts 8m, reaches tenpai on 8s, and declares riichi. Then the record: 16th NPM class, 7-dan on Tenhou with a rating of R2056, 17+ years at the table, and the Shinjin-ou final table.

NewThe dealer riichis, then a second player chases, and you can't fold to both with every tile. Here's how to sort the two threats like a field medic, and the Houou numbers that decide who gets your safe tiles.
NewRiichi has no inventor anyone can name: it began as a first-discard rule said to come from northeast China. A 1952 newspaper rulebook set down riichi as it's played today, and dora, red fives, ura dora, and ippatsu grew up around it.
