GambitVB Free Chess Software 
 
  About The Author 
 
Willem Rens, a retired professional, wrote a chess program named Gambit-80 around 1980. The program was one of the first reasonable playing programs in the Netherlands. It became commercial and known in tournaments where computers played against computers. The language for the program was the Z80 assembler language running on RadioShack’s TRS-80, one of the early home computers. The author had several ideas to improve the program, but most failed hopelessly. Reasons were hardware limitations (16k of memory!) and not to forget the complexity barrier. About thirty years later, a lot happened in computer land. And when Microsoft introduced .NET, the author became challenged to try his old ideas about chess programming with Visual Basic. The result was named GambitVB.

GambitVB plays reasonable chess and offers a complete and friendly user-interface. GambitVB is not written with the intention to be a chess champion, but will beat the common chess player. The emphasis is on well-structured, self-documenting, object-oriented code. When the author wrote his first program, he was inspired by the book “Sargon: A Computer Chess Program” written by Dan and Kathe Spracklen. Today, a web site providing free software and free documentation looked an obvious choice to inspire others.
