The Chess Suite can only be obtained on a personal basis. Please contact me via e-mail and include full name and postal address, as well as all commercial chess organisations or companies you are associated with (even if you are just a volunteer who e.g. contributes to ChessBase or chessgames.com). 

Please add also a brief description of what you want to use the Chess Suite for. I prefer to support non-commercial projects, e.g. books on chess history, database maintenance and research projects. But commercial projects can also come into question.

In case you are just a little curious about the software, just ask.

The Chess Suite is distributed as a personal copy and around September/October each year I will ask all users for feedback on missing features and problems observed, as well as asking if they would like to receive a copy of the next version, which is usually released in early December.
