I read a Wikipedia article about the popularity of chess handicaps in the 18th and 19th centuries. Many master players would offer odds to a weaker player in order to convince them to wager money on a game of chess. I was curious how MadChess would fare in such conditions, so I created an opening book of typical chess odds, and ran a series of matches against elite engines. MadChess had “move” odds in all the games. That is, MadChess played white. Two move odds means MadChess played white and made two moves to open the game. The time control… Continue Reading

I’ve added features to improve MadChess’ value as a sparring partner and analysis tool. I spent a lot of time implementing an algorithm that reduces the playing strength of MadChess. In chess GUIs that support the feature, MadChess will automatically adjust its playing strength to match the user. See the User Guide for details. Source code and EXEs available on the Downloads page. Added UCI_LimitStrength and UCI_Elo options. Added chess personalities from young child to expert. Added MultiPV (display multiple principal variations). Enabled PVS search for MultiPV or when ScoreError > 0. Do not reduce search horizon of pawn pushes.… Continue Reading
I work as a Software Architect at an insurance company. We're building a modern tech stack in the cloud using C#, Azure, ASP.NET Core, Angular, TypeScript, etc.
I've always been interested in chess (a game of complete information) and poker (a game of incomplete information). This is my attempt to write chess-playing software. I'll get to poker later.
