Pedro Martínez: all these games have major problems in the implementation of the rules and there are no signs of them being fixed anytime soon.

That seems to be on par for Brainking. If a new game has been added, there's a short period in which bugs may get fixed. Afterwards, it's always declared as "this is just the way we play this game on this site".

MTC: In Russian Checkers, it is not mandatory to make the longest possible jump.

Currently, Wikipedia writes Jumping is mandatory and cannot be passed up to make a non-jumping move, nor can fewer than the maximum jumps possible be taken in a multiple-jump move.. Or course, an article on Wikipedia isn't more than the opinion of the last person editing it....

joshi tm: "Ultra-weak" means it's known what the result of the game will be (or cannot be) given perfect play by both players. PahTum for instance is ultra-weak solved in the sense that the second player cannot win (strategy stealing argument). But for a game to be solved ultra-weakly, you can prove the result, but you do not have to have a method reaching that result. Weakly solved means that you have a method for one player to force a win (or draw) from the starting position. Strongly solved means that you from any position what the result will be, and how to archieve that result with perfect play from both sides. Chess is partially strongly solved for up to 6 or 7 pieces (that is, for any legal chess position with at most 6 (or 7) pieces, optimal play for both sides is known)

MrWCF: You might get more response if you make your references to games actual links.

MrWCF: Oh yes, I've noticed it as well. It annoys me too. I've even been yelled at for resigning with the argument my opponent didn't get the satisfaction of "moving out the last stones".

But there are other sites where it's worse. There's one site I play where resigning is actually punished (you get extra negative 'tie breaker points' making it harder to win a tournament if another player scored the same amount of match points).

As for your point 3), I've heard that often. I don't buy it. Little skill is needed to play out a position where the situation of the opponent is hopeless. No tactical or strategical action will happen that will be useful to the losing player. If the losing player wants to learn something, he'd be better off starting a new game instead of continuing a game that's lobsided.

I was quite surprised that in Cam, a position with both players having one piece left was declared a draw. Unlike Camelot where you need to occupy your opponents castle with two pieces, in Cam, only one is needed for a win. With both players having one piece left (and the pieces had passed each other), it would have made much sense if the game continued.

Could someone clearify the rules to me? If a player can make a knights charge, but not a regular jump, is he forced to make the knights charge, or may he opt for a canter or plain move as well?
