A Message from Thad Suits
“After thirty-six years supporting chess tournaments all over the world with SwissSys, the time has come for me to pass the baton. I am delighted that ChessRoster will be taking SwissSys to a new level, implementing the kind of complete tournament service that is the logical next step in the program's development. With Colin Scheriff's vision, SwissSys will become the hub of a system to make tournaments more automated and much easier to manage.”
