Good post V.
That is the basic endgame knowledge that every players needs.
It's must know stuff. Even I know it.
I screwed it up OTB once, I put the Rook on the wrong rank.
But you can make slight errors in some endgames, especially if you are
material up and get away with it.
I had to go back and do it all again.
I touched on the Lucena a Blog ago:
"Championship Games Download + The Bridge." The bridge is the Lucena.
And showed a example of a player missing it.
There is also a link to a Lucena vid on it which I highly recommend.
Not just for the subject mater but how to actually do a chess vid for the net.
Again good stuff V.
