Superpawn comes with a single C++ source file <ref>[https://github.com/johnwbyrd/superpawn/blob/master/Chess.cpp superpawn/Chess.cpp at master · johnwbyrd/superpawn · GitHub]</ref> , requires a [[Cpp#11|C++11]] compiler,

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.
