Home * Engines * TDChess

a chess program by Jonathan Baxter based on KnightCap and its TD learning. As mentioned by Jonathan, TDChess is about 5-6 times faster in nodes per second than KnightCap. KnightCap had a really complicated evaluation which he had "dumbed down" a lot to get more speed. He also changed the search a fair bit, including how it does move ordering now on the basis of a static exchange evaluation, and how quiescence works. The sorting of moves has become lot faster due to sorting on demand. Also the book learning is very different from the original KnightCap [1]. TDChess won the NC3 1999 Australasian National Computer Chess Championship [2].
