A sample review
Every review is a written breakdown of your key decisions, with a scorecard and the pattern that costs you the most.
Review · Tenhou 鳳凰卓 · South
- You cut 9s. The 4s draw completed 3-4-5s, so 8m is the only tile that connects to nothing. Cut 8m: tenpai on 8s.
- Dealer riichi on turn 11. With a cheap kanchan and 2 safe tiles, this is a fold spot. You pushed 5p and dealt in.
- Three times you kept a lone honor over a connected tile. Cut them earlier and your hand stays one step faster.
- Tile efficiency7/10
- Defense5/10
- Hand value6/10
- Placement play4/10
- Cut isolated honors before turn 6
- Fold cheap hands against dealer riichi
- Replay this game with the notes open
