I stopped playing regular checkers after finding that some of my opponents were using programs such as CakeManchester or Chinook to make their moves. So, I downloaded Cake Manchester, from Martin Fierz's homepage and now, when I want to play a good game, I do it against my machine. What I found a few months ago, was that Martin also developed a suicidal version for his Cake (here known as anti-checkers). I downloaded it too, and after playing some games against it, I found very familiar moves from games I had with two or three opponents, specially from ItsYousTurn.com. I surely hope that people will reconsider the use of such programs in their moves, or there will be no interest at all to keep playing those games here, against real players, when in reality we're doing that against a machine...

By the way, the site to download those programs: http://www.fierz.ch/checkers.htm
