Of particular interest to me is the earlier stages of development of computer chess programs, primarily through the 1970's (which I was involved in). The main contenders for best program from that era until today also has my interest, as does Kasparov and his "deep" involvement with computers.

For Delphi and C++ Builder. Provides a 2-Dimensional chessboard with a drag and drop interface that can keep track of a game and allows full customization of the bitmaps for the pieces, squares and border. Optionally the board is resizable at runtime. All common chess events are implemented (OnLegalMove, OnIllegalMove, OnCapture, OnCheck, OnMate, OnStaleMate, OnDraw etc.) The component includes the engine of Tom's Simple Chess Program and calculates using its own thread. Optionally it allows you to use your own custom engine instead as well. Just drop a Chessbrd component on a form and you are very close to a complete multithreaded chess application. A Delphi example project has been included to demonstrate the common features.

Many years ago, I submitted a set of four objectives that I challenged the Chess world to strive for. Here I list the progress towards those challenges.
|MasterChess (formerly Bookup)
by Mike Leahy
Master Chess is a program for analysis of chess openings that blew me away when I first saw it. If I was competing in chess, it would be a no-brainer to buy it and use it to dramatically improve my play. If you play chess, get it and use it!
You can buy Ebooks of opening analysis and load them into MasterChess and contrast them with each other, or compare them to full games you load in pgn or gm2 (MasterChess) formats.
I won't try to explain what MasterChess can do. These tutorial videos give you what you need.
This is the part of MasterChess that excited me the most. I write in my challenges: "I was always intrigued by the possibility of putting all these positions into a single database and back-calculating the optimum moves at each position as a chess program would. This would be akin to solving the game of chess for the small sample space of positions that are in the one book of openings. What would happen? Would white be able to force an advantage? Would black be able to equalize? Or maybe white is zugzwang in the opening position, and black will come ahead.".
