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 

MrWCF: This rule also exist in other variants, like in Portuguese checkers, and it does matter, sometimes. The question is that you can only jump once over each piece, in your move. To guarantee that you respect this, the "mechanism" is that the jumped pieces are only removed in the end of your move. If pieces were removed just after jumped, you would be ignoring that rule.

I don't know if I was clear: the question is not the piece taked (jumped) twice. The question is that a taked (jumped) piece works like a "wall" - that's the spirit of that rule!

Stardust: 3334 is a lucky guy! ;)

John Toomey, you are right. And IYT it's not the only place where it happens: in REAL LIFE (well, I'm talking in classic checkers case), those are "draw rules" wich are described and used. And some other rules are available (Once again, I'm talking in classic checkers): with 3 queens, one of them in the "main central line" (We call it "the river", in Portugal) Vs 1 queen, you have only 12 moves to win the game. Or if you have 2 queens and a pawn, Vs 1 queen, you have 20 moves to move your pawn, or it is a draw.

Manuel M: Eheheheh.

For those who can't read in portuguese, I can explain you that we (me and Undertaker) were calling brady as "HE", but Manuel explained us that we should say "SHE".
