TN: For this next set of problems, the questions are on "translated" pages and the answer are in spoilered text in the same post. You can see the Pei in the tenhou screenshots, but I added text for them anyway.

>3s riichi
>Defence is important in sanma, but so is offence. With three dora and an A-class ryanmen, it's fine to push dangerous tiles. If you fold a hand like this, you won't have many chances to push.

>In the match this was a deal in, but we don't care about that at all.
