Problems to use with MyGoGrinder

It's very easy to add problems to your collection - just put the SGF files into the MyGoGrinderSettings/problems folder (or a subfolder). You can organize them into folders however you like - this will change how they are shown in the selection window. Many of the collections below will have multiple problems stored in one SGF file. Use the Split command (tools menu) to separate them, so that they can be used with MyGoGrinder.

Places to get problems

• goproblems.com has more than 9000 problems, and they work with MyGoGrinder. You need to do something to get them - see the short overview at Sensei's. Tools for splitting that collection are available at Sensei's: disort.sh (f.Linux), sort.bat (f.Windows) and Update-Disorted (Linux, update a sorted collection)
• Cho's Encyclopedia of Life and Death is an excellent collection containing almost 3000 Life and Death problems with solutions and refutations for wrong answers. It can be ordered from Kiseido. Last time I (T.K., ~2006) checked their website, it was not listed, but I was still able to order the product by phone. The problems on the CD are in a non-standard format, but you can use a utility to convert the problems to SGF. Bill Shubert has written a C program to do this. Ulrich Goertz has translated the program to Python, and it is available on Ulrich Goertz' site (the UliGo home page).
• There are several collections of problems, totalling about 1800, also available on Ulrich Goertz' pages.
