KnightX, a Chess Engine Communication Protocol compliant chess engine by Christophe Jolly, written in C, and alias and successor of the native Windows program Techno Chess. KnightX, supporting WinBoard, was first published in December 1999, and since 2004, KnightX 1.86 runs under Linux via XBoard. KnightX played the Massy 2003 French Programmers Tournament, and the FCCC 2003 French Computer Chess Championship. After a long break from 2005 with KnightX 1.92, Christophe Jolly had his comeback in February 2019, when he released Knightx 1.93, continuing with subsequent versions.
