Brute Force, a chess program by Louis Kessler that participated in the 8th and 9th North American Computer Chess Championships in 1977 and 1978. Brute Force was a Tech like program, including such features of an iterative alpha-beta routine, a quiescence routine using swap-off values, and an evaluation function based on the opponent's mobility [1]. At the 9th NACCC, it suffered from an "en passant bug" twice [2], which turned out a wrong implementation due to Kessler's misinterpretation of the rules [3].

3. ^ Quote by Louis Kessler from A Memorial to BRUTE FORCE:
   As far as the en passant bug goes, it turns out this was my own misinterpretation of the rules. I read that "The en passant capture must be done on the very next turn, or the right to do so is lost”. I had interpreted that as losing the right to do any en passant for the remainder of the game, not just for that one specific en passant. My personal lack of experience in tournament chess led to that, and it cost me.
