I would like to propose a small rule change for these games on Tiltyard. Specifically to the goal values. Currently its 100 for having more pieces than one's opponent at the terminal state, and 50 for the same number. I would like to suggest that the 100 become 90 and that the full 100 is awarded only if the terminal state is not terminal due to the turn counter reaching 100 (i.e. - capturing all ones opponent's pieces scores higher than simply having more when the game expires).
The reason I suggest this, is that having watched play in a fairly large number of instances, an extremely common pattern is a 20-25 move tactical exchange, resulting in one player getting a material advantage, followed by 70-80 moves of moving a king back and forth to kill time, which is uninteresting (both as a viewer and as an academic exercise in game tree search) and time-consuming. Providing a goal incentive to 'clean up' should make games potentially more interesting, and also allow improved differentiation of the better players.

Feel free to submit a pull request on github.com/ggp-org/ggp-repository/ with new versions of these games that fix the rules, though in this case it might be better to add a new game entirely with modified rules, since there's nothing buggy with the old rules. Keep in mind that the "checkers" rulesheets are fairly old; the newer preferred checkers-style game is "englishDraughts". I'm not sure how that game handles this situation; maybe Alex can comment on that?

The englishDraughts version of checkers requires one player to run out of legal moves (which usually means having all their pieces captured) in order for the other player to win. It also uses a different approach to determining if a draw should happen, which may potentially make games last much longer than other checkers variants; it requires 20 turns to have passed since the last capture or non-king move before it declares the game a draw. (This is a bit shorter than the real-life version of that rule.) You can see from the match results here that draws are fairly rare for this version: www.ggp.org/view/tiltyard/games/base/englishDraughts/v0/
