Zach's Chess Test (ZCT)

The chess program known as Zach's Chess Test has been in existence since around 2003. I created various engines around the time period of 2002-2003. After a hard drive crash, a new source base was created. The idea was to create a good chess engine using bitboards. Though this program served as the basis for much of my chess programming development as well as new ideas, the project eventually dwindled into weakness, bugginess, and unintended obfuscation of code. The old code base was abandoned, and an entirely new engine was created on June 1, 2005. This code base has been designated ZCT 0.3.x. (x currently = 2415)

The engine has been in more or less continous development since then.
