Master Chess is a 2D chess game built in Unity and C#. Players click a piece and then the square to move it to, and the game continues until checkmate or a draw. It dates from mid-2023. Two years later he wrote an online version, ochess, for the browser.
I build ontologies, knowledge graphs and the systems that run them. This page is one: ask it anything, and it writes SPARQL, runs it in your browser, and answers only from what it finds.
