Crashtest Dummy (Crash Test Dummy, CTD),
a Chess Engine Communication Protocol and UCI compliant experimental chess engine by Richard Pijl, intended as a test bed for his primary engine The Baron. Richard started with CTD in about 2004, when he was getting nowhere with improving the Baron. When CTD was able to play a game, he decided to give the Baron one more look, instantly removed the bug that was blocking improvement and kept CTD in a drawer. At another point Richard was about to retire the Baron and to work only on CTD, as its successor .
