I tried using this, but it left me with the impression that it was unprofessionally done.

1. The board is not correct. The black square must be in the left corner. While this may seem like a small quibble, it changes the patters so that squares like e4, which should be white, are now black. This makes it difficult to play.

2. There are apparently no openings programed into the computer. Since openings are so complex, simply using an algorithm to find good opening moves does not work well. So, this program will almost always start out with bad first moves.
