Hi, I'm coppro. I play mahjong a little.
Games of Note
- nagashi mangan
- another player's suuankou
- dealing into kokushi
- not dealing into kokushi
- honroutou baiman
- daburu riichi nomi
- daburu riichi ippatsu chiitoi aka 2
- me coming in 3rd because kamicha deals into mangan and oyappane double ron in east 2
- suufon renta
I have other interesting games, but my tenhou client doesn't record logs for some reason so it's difficult for me to get links. No other yakuman have happened in my games, except a kokushi in a real tiles game.
Physical Games
Riichi with 1 dora (forget exactly which):
Ron: 
Just missed a kazoe yakuman.
Riichi with:
Dora indicators: 
Uradora indicators:
If I had won this hand with any tile, it's riichi chinitsu dora 6, for kazoe yakuman. But my kamicha bailed and dealt into shimocha's 5200 points instead. The riichi wasn't really necessary (it was at least baiman with chinitsu dora 3), but I spent so long hemming and hawing over declaring that at that point, all my opponents knew I was tenpai so I didn't really have much to lose. (and there was no chance of me getting chuuren, with the remaining 1s all dead).

No yakuman yet. Been tenpai for suuankou, kokushi, and kazoe. I have gotten nagashi mangan. I was also one tile away another time (and had the safe final tile in hand), but someone won with 5 tiles left in the wall.
