=Description= 
The program features a [[Principal Variation Search|principal variation search]] with [[Transposition Table|transposition table]], and a basic [[Material|material]] and [[Mobility|mobility]] [[Evaluation|evaluation]], considering [[Middlegame|middlegame]] and [[Endgame|endgame]] [[Piece-Square Tables|piece-square tables]], [[Tapered Eval|tapered]] by current [[Game Phases|game stage]]. The [[Board Representation|board is represented]] as [[Array|array]] of 64 [[https://en.wikipedia.org/wiki/Pointer_%28computer_programming%29|pointers]]to [[Pieces|piece]] [[https://en.wikipedia.org/wiki/Object_%28computer_science%29|objects]]. A piece is an [[https://en.wikipedia.org/wiki/Abstract_type|abstract class]] with [[http://en.wikipedia.org/wiki/Virtual_function#Abstract_classes_and_pure_virtual_functions|pure virtual]] //PieceValue// and //GenerateMoves// methods, implemented in the concrete, derived piece classes including NoPiece for empty squares. 

=Quote=
by Superpawn's author, [[John Byrd]] <ref>[[http://chess.johnbyrd.org/|Superpawn]]</ref> :
|| {{Superpawn is an excellent example of the “objects gone wild” style of programming, in which Everything Is An Object. Even the pieces themselves are objects; they know how to move, capture, etc. This of course slows down the [[Move Generation|move generation]] and evaluation process immensely, making this program irredeemably slow in tournament conditions. However, its logic is easy to follow and extend as you see fit.}} ||
