dvoretsky's manual might be excellent, but I can't stay conscious reading it. I hope the silman book offers something in that regard...
I'm now going through (drilling the examples against fritz) the karsten müller endgame dvds, and although dvd's can't contain as much information as a book, I'm still constantly amazed how much there are elementary theory I don't know. well, I knew
most of the basic stuff, but watching karsten slamming the variations at lightning speed made me realize I was no where near mastering them, making my feeble knowledge almost useless. so now I'm drilling the stuff until I can instantly recognize & perform the necessary procedures.
and unlike reading the dvoretsky book, it's actually fun
