Hi. As someone who started mahjong in July, I managed to claw my way up to 1-dan on Janryumon. But to improve further I bought Totsugeki Touhoku's Oshiete! Kagaku suru Maajan
. Of import is that Chapter 5 is a set of thirty problems. These problems are chosen to that there is no half-half answers. Totsugeki specifically analysed them and had them peer reviewed. Only the problems with unanimous answers are included. So I have decided people on this forum can benefit...assuming you don't have your own copy.
Oh, I don't have a program that lets me draw up these problems, so I'll be writing them out longhand. If you know of a program please tell me.Notte benne:
