Hard to say; perhaps 2 weeks if I would give it priority.
Ok, thanks. I was just trying to get an idea, not asking to make it priority. It'll probably take me a couple of weeks to get Quadrox ready. I'm going to start with FIDEs vs. Clobberers because that will be easiest. No asymetric pieces or range-limited sliders.
I'm glad you mentioned endgames - I was going to bring that up. At a minimum, I need to determine under which conditions the game should be terminated immediately because there isn't enough material for checkmate to be possible. (E.g., any number of BDs and FADs vs. a lone king if they are all on the same color.) But, yeah, like you I also want to identify those piece combinations where the game should not be terminated because mate is theoretically possible if the opponent walks into the corner but the evaluation function should return zero (e.g., king + fibnif vs. lone king.) Your Javascript checkmating app is really awesome and answers the question for single pieces. I'm glad you're going to work on determining the answer for multiple pieces. Can a king plus two WAs force checkmate? I doubt it but I don't really know and I have no experience with endgame database generation.
It sounds like you're being really ambitious though. Recognizing KBBPKBN as drawish is really advanced. Throw in all the fairy pieces from cwda and the number of permutations is out of sight...
