Here are 22 endgame positions. Some have been posted previously by me but most are new. Also in most the critical move means the difference between a win, draw or loss.

Let me know if any have multiple solutions. Note that XEND22 is a follow up to the Louguet-2 end #9. Kf5 wins while fxg5 draws. XEND09 might be a knowledge one as in general it is not always best to push pawns. XEND14 involves a nice transition to a won endgame but the other choice, Qb7+ looks good but will most likely draw due to the Queen checks. Knowledge too may be needed to solve this one. Anyway, have fun with these and share your results. I'd like to eliminate the ones that are too easy for all programs.
