Arthur is a strong Dutch amateur program. It has finished as the best amateur program in the [[Dutch Open Computer Chess Championship|Open Dutch Computer Chess Championships]] for the last three years, performing reasonably well against commercial programs. The program consists of a platform independent chess engine, which is connected to a [[GUI|graphical user interface]] for the [[Macintosh]]. A [[WinBoard]] version will be available in the near future. Arthur is quite capable tactically, but it tends to play a positional game, when given the chance.
