Vapor, (Vapor Chess) an UCI compliant chess engine by Mike Leany, written in C, since October 2010 no longer vaporware, and since November 2019 published as open source on Github.

=Description= Vapor is a rudimentary, didactic engine and lacks state of the art search techniques and evaluation terms. It represents the board with a little-endian file-rank mapped bitboard definition, and applies Hyperbola Quintessence to determine sliding piece attacks. Search is plain alpha-beta with transposition table, check extension and quiescence inside the iterative deepening loop , considering material and piece-square tables for pawns and knights as evaluation terms at the leaves.
