A Java-based Go client bundled with the powerful open source GnuGo engine
Pros & Cons:
Java-based JagoClient has a good user interface and comes bundled with the powerful open source GnuGo engine (several versions of GnuGo are available here).
JagoClient reads and writes the standard Smart Game Format (SGF) and XML based format, and can also play any other engine supporting the Go modem protocol.
On launching JagoClient from the Windows start menu go to "Actions", click "Play Go (using GMP)" and set your handicap to zero. And you should be ready to Go!
This program needs Java Runtime Environment, which is available here if you have not installed it.
