Telepath,
a private, UCI compliant [1] chess engine by Charles Roberson written in C++ [2], development started in 2004. It had its tournament debut at the CCT7, February 2005. Telepath played all further CCT Tournaments, and also the ACCA Americas' Computer Chess Championships and ACCA World Computer Rapid Chess Championships.

Telepath uses bitboards as basic data structure and board representation [3]. Its King safety considers tropism and square control by a detailed analysis of attacks and defences around the king [4].
