GoGrinder

Today I am going to present a nice and handy program to you that I found quite a while ago on the net and which I find to be very useful: GoGrinder. It’s a Java program for practicing go problems basically and uses the standard SGF format. Here is a quick list with all of GoGrinder’s features (from the publisher’s homepage):

• Loads go problems that are stored in the standard SGF format
• Allows refutations of incorrect answers to be included in the problem files.
• Remembers where you were when closed and restarted.
• Can save progress through problem sets to file, so you can go work on a different set of problems, and then pick up where you left off.
• Filters the available problems based on tags associated with the problems, e.g. Life and Death, Tesuji, etc.
• Allows the selected problems to be sorted in various orders - by difficulty, random, etc.
• Keeps statistics on the number of problems that have been correctly solved in the set, and long-term stats for each collection of problems.
• Allows import and export of problem sets.
• Allows editing of the current problem in an external SGF editor
• Splits files containing multiple problems for use with GoGrinder.
• Comes with 347 problems, ranging in difficulty from 25k - 4d.
• Thousands more problems are available for free on the internet - links provided in the documentation.

The program is available in English, German, Russian, French, Spanish, Portuguese, Chinese and Czech, so everybody should be able to use it, I guess. The best feature is not mentioned yet: the program is completely for free!!!
