Feng (Tenhou 7-dan) released a strategy guide on Facebook for players at intermediate level (Tenhou 1-6 dan).

This has now been given a home outside Facebook by Rosti (formerly of this parish).

It assumes familiarity with the content of Daina Chiba's Riichi Book I which is available at the link below.

Started to read it but it's going to take a while.

Is Feng the same mrfeng who is also formerly of this parish? (Forum?)

Yes, it probably lends itself to reading in chunks - or picking out topics of interest.

Doh! I think I missed one - given the Singapore location, likely the same. Another RM forum graduate.

Been reviewing some of the other stuff written by mrfeng. Although he had only 41 posts on the forum over a 15 month period, 10 related to educating me on "another gameplay question" and 20 were commentary on WWYD.
There were many lengthy good discussions.
I learned a lot. Thank you, mrfeng.
