Vice, (Video Instructional Chess Engine)
a didactic open source chess engine by BlueFeverSoft, written in C, and introduced in a series of 87 + 8 YouTube videos from May 2013 until January 2014 [2].
Vice represents the board with a 120 square array and additionally has some bitboards for pawn stuff. It applies an alpha-beta search with transposition table, null move pruning and quiescence inside an iterative deepening framework. It is compatible with the UCI and the Chess Engine Communication Protocol, and since version 1.1, supports the PolyGlot opening book format [3].
