The Exotherm draw problem

I'm hoping to deploy Exotherm to the FICS relatively soon. There is a problem I'd like to address first, though. It plays poorly in the endgame and usually thinks it's doing much better than it is. It walks various pieces all around the board without making any progress. I would like to have it accept draws if it detects no progress has been made after some time. Playing it would be much more enjoyable if one didn't have to go all the way to draw by repetition or 50 moves when the bot can't figure out what to do.
