The analysis board currently says "Checkmate is now unavoidable" when it finds a combination. It should say "Forced checkmate is now possible" (or perhaps the shorter "Forced mate is now possible").
I see the advantage: It is more precise, because checkmate of course is avoidable (with the opponent's help)
But there is also an disadvantage: It is from opponent's pov.
Maybe "Opponent can force checkmate now"?
It is precise enough. "Checkmate is now unavoidable" - I really can't avoid it, if my opponent makes the right moves on which I have no influence.
