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 programs are commercial, although many offer a free version or a free trial period. If you can afford it, buy Many Faces of Go with its considerable tutorial material.
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.
Some freeware and shareware Go-playing programs are available from our 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 and TurboGo.
