Notes:

1) The winning side may sacrifice material in order to reach a winning sub-ending (e.g. in wKc2,Qf2,Nb2,Ba3 v bKa8, White plays 1.Qa7+ to force a capture as soon as possible, even though it favors the losing side).

2) For use with chess engines: Depths reported may be after the moves, leading to strange results in some cases (e.g. with wKc2,Qe4 v bKc5,Rh7, White plays 1.Qf5+ Kb4 2.Qe4+ Kc5 etc.)
