A better solution, I think, is the simultaneous installation of the Anti-Chase and Auto Draw rules. It seems to be a very good way of answering all objections as well as anything heretofore proposed.
Things have been suggested like beginning a Draw counter when there are only so many pieces left on the board (me, I'm guilty!), or when there are no miners left. But these things are at best arbitrary, and at worst, in the case of the no-miners suggestion, information-divulging. A blind limit on moves between attacks, even though clearly arbitrary, is the most unobtrusive thing in my opinion to base an Automatic Draw on. And, combining the Auto Draw with Anti-Chase rules seems a good regulatory marriage.
I say err on the conservative and make the numbers high to begin with. Start with Anti-Chasing and a 20 full bind limit per-incident (this preserves the chasee's rights) plus a 150 total game limit per player, with the penalty of a loss if violated. Then layer that rule with the Auto Draw rule which gives, from the very start of the game, 100 moves per player to make an attack. [Make the Draw counter restart if EITHER player makes an attack.] If 150 full-binds (the pb/fb kind) of chasing is allowed as a total game limit in the Anti-Chase rule, then that gives a chaser 50 chasing full-binds before he runs the risk of losing out on his chance at an Auto Draw. That is, he is allowed 150 total chase moves, but if he has used 51 of them, he will get an automatic loss if he chases 99 more times. He could still play for a Draw if he desired, but, since he must make at least 100 moves between attacks for the Auto Draw to kick in, he will automatically lose if he chooses to attempt to chase his way into a Draw.
Is this giving too much rope to the chaser? Not enough? Is this Draw method fair?
Whether you agree with the numbers, it seems to me that this approach ignores many problematic variables, including but not limited to the number of pieces remaining and/or the power of those pieces. That is a good thing. The Anti-Chasing proposition affects the heinous chaser and the Auto Draw only affects games where nothing is demonstrably happening.
