Go-playing Programs

One way to improve your Go may be to play against a computer program. If you are a beginner, almost any program will do for this. However, as you improve, you will find that playing a program of around your own strength does not necessarily improve your Go - it may make it worse: instead of learning good style, you just learn to play the particular moves which that program is unable to handle. The best program available in 2000 had a Nihon Ki-in 2-kyu certificate, but British 1-dans could give it nine stones and beat it.

The best programs are commercial, meaning that you have to pay for them. If you can afford it, buy Many Faces of Go with its considerable tutorial material. A few years ago, if you are stronger than 8-kyu, you should have been able to beat any program, so playing strength was not an issue. If you are around 10-12 kyu, you might think it important to buy the program that is best at beating you. Then you should consider Go++ and HandTalk. Go++ has a much nicer-looking user interface, and HandTalk is harder to beat. But neither of them has any of the tutorial material that is part of Many Faces of Go.

Since 2007 programs using the Monte Carlo method are becoming available and these are certainly at dan level on small boards at least. Leela and the latest version of Many Faces of Go feature this method.

Current strengths of the development versions of commercial and private programs can be seen at the Computer Go Ladder.

Some freeware and shareware Go-playing programs are available from the BGA's Software Catalogue. The best of them are Igowin which is a free version of Many Faces of Go, and EZ-Go which is a free version of EGO. A recent strong program is Leela with its free version LeelaLite. Peter's Go is a good one for improvers as it has different board sizes.

Also worth a mention are GnuGo, Minimago, SW1 and TurboGo.

Some commercial programs have shareware or free versions. HandTalk has a 9-by-9 version which may be freely downloaded from Yutopian.

Peepo.com is a complex data visualisation program, allowing you to play online (with certain browsers like Firefox) against the pachi engine. As of February 2012 it's open for initial user testing and feedback.
