Came across this picture of a round Go board on the net. For whatever reason, I became inspired to write a Windows 95 program that would print out this round board across four sheets of paper which can be taped together.

I have now made the board available in PDF, so it can be printed out on any computer (Mac/Windows/UNIX) using the free Adobe Acrobat Reader.

The Win95 C++ program that generated this image is available for download, and you may need. two VC++ MFC DLL files. (But if I were you, I'd get the PDF version.)

This is really a fun shape to play on. Standard Go rules apply, and each point still has four liberties (even on the outside edges).

As of 5/12 the person who invented the round go board idea e-mailed me. It was Harald Schwarz ( who introduced this form of go during the European Go Congress Summer 1996 at Abono Terme in Italy.
