Checkers Draw

Can you add a feature where a draw automatically occurs when the same moves keep repeating?
Although I suppose that if this was implemented, one could vary the moves enough that it wouldn't be noticed.
Perhaps it should just be that when the game is down to all kings, and both players have the same number, it would automatically draw.

The issue is that certain players are not willing to draw a game. (They have a long winning streak, and a draw would end that streak.) We are down to two kings each, and it is impossible to win (without making an obvious mistake); we just keep moving the same piece back and forth. I don't think I should have to forfeit a tied game just to get out of this.

Here are the last 16 moves:

c7-b8 d4-c5 b8-c7 c5-d4
c7-b8 d4-c5 b8-c7 c5-d4
c7-b8 d4-c5 b8-c7 c5-d4
c7-b8 d4-c5 b8-c7 c5-d4

There are two kinds of people: 1) Those who can extrapolate from incomplete data.

I've done some research into how this is handled in tournaments. If both sides want a draw, it can be done at any time. If only one side wants a draw, then the basic idea is that you have a certain number of moves to show an advantage; if there is no advantage then the game is declared a draw.

For Braingle, this could mean that after a draw is offered,
1) if neither side has advanced a piece towards the king-row (i.e. had a king crowned) AND
2) if no pieces have been removed from the board (i.e. no jumps)
within 40 moves, the game is a draw. (some sources say 50 moves, but have the same two criteria.)

We've repeated the same moves 60 times now...
