American Go E-Journal

Guanzi Pu (Sensei’s Library), a classic Chinese problem collection from 1660 of 1473 problems has just been added to the Learn Overview page, based on a post on L19 . It is one of the problem collections that is considered high dan/pro level, although it may be the easiest of those. Some problems are easy at the beginning, but ramp up. Includes a PDF with multiple problems per page, but doesn’t include the solutions, typeset by pwaldron. Also includes a PDF (ebook) version that includes all 1473 problems (plus a few extras) and answers from p2501 on L19.
