Follow the logic

 The latest tournament clearly showed: it is time to fix the holes in my endgame bucket. I dropped 2.5 points in 5 endgames. The amount of endgames is rising (5 out of 7 games) because I fixed my opening problems and my opponents get better.

My method says: fiddle around. Fiddling around leads to a clear insight: invasion is paramount in the endgame. Apparently I don't know how that works. I need a firm grasp of corresponding squares. I concluded that already in 2006, but back then the time wasn't ripe. Now it is.

The sloppy videos on the internet aren't of much help. I need a good source. Claude recommends Dvoretsky. Which I happen to have in my library. So let me dive in head first!
