Riichi Strategy - Iishanten Peak Theory

[@japanbouldering4582]

Thanks for this video. I bought one of G. Uzak’s 何切る？ books recently and I’m glad to see you introducing topics from his other books as well.

Thanks for feedback! All his books are great, and I hope bringing more awareness and translations will eventually lead to a fully translated book to be published in the future🤞

[@treehann]

it makes perfect sense. Keeping track of what's discarded to figure out the peak isshanten in practice is so hard though :D

[@RiichiMahjongCentral]

Practice makes perfect!! Haha

In the second example, what is the idea behind keeping 89s over 13s? 13s has opportunity to improve to a ryanmen if 4s is drawn even though it loses chanta. Thanks in advance!

Thanks for the comment! The book says it is better to be flexible and have the ability to call Pon because of the amount of blocks👍

[@Shizukatz]

But both of the blocks I mentioned are non-pair blocks, so not sure where the Pon comes into play.

[@RiichiMahjongCentral]

You have 3 pairs and 1 of them can be used as a Shuntsu. If you compare the 13S, it is a Kanchan wait. The other block is a 89S, and already double sided. If you will be dropping either one, I think you would keep the double sided 89S right?

[@Shizukatz]

How is 89s double-sided when it's a penchan that only waits on 7s?

[@RiichiMahjongCentral]

Sorry typo, it was 78S😭
