>---: You get tenpai on turn 6.
>Owata: Instand riichi even with a penchan. Sanma has less tiles, so for likelihood calculations the denominator is smaller. Thus winning a penchan is easier than in yonma. But if someone chases, it's also more dangerous. The opponent gets the same benefit after all.
>---: And yet it's a riichi even with this potential risk.
>Owata: The fact that I have a 6p triplet helps the 7p wait out a bit.
>---: You're saying that since only 6p is left, it's harder for the others to use 7p.
>Owata: It's also possible that someone else has a 7p triplet. I can't know if that's the case. In last place I have to take some risks.
>---: Do you think it's better to be aggressive when you're uncertain?
>Owata: It would be different if I knew there was danger, but in general I think it's better to be aggressive when you don't know if there's danger. Folding against a threat that may not exist just seems like a waste.
>---: Your push is rewarded with a tsumo.
Not making another post just for the tsumo screenshot. It's riichi tsumo, 500/1000.
