So I really don’t understand, what have I done if you ignore my submissions?
Nothing in particular. But I don't consider it my task here to judge and publish submissions. I do only look at those when I have time, and only comment on them when I notice something that should be pointed out. And at the moment I am pretty busy because I have been on holiday, and am furthermore working on writing articles for two variants of my own.
So for me, piece is more valuable if it’s easier and more possible to checkmate in pure late endgame.
If ease of checkmating would be a criterion, you would probably consider a Rook more valuable than an Archbishop. And Knights and Bishops would not be worth anything at all, as these cannot force checkmate. But to get into a position where you can force checkmate, you first have to gain the material advantage that requires. You cannot do that if you sacrifice the more powerful pieces for weaker ones just because the weaker ones are easier to checkmate with. If you do that, you would get checkmated yourself. So it is important to both know correct piece values, and master elementary checkmates.
