Rook Endgame

@N78_Training I am very impressed with your analysis. I couldn't find any single line to object your evaluation. I have also created a chapter with your analysis because I found it very useful. What is interesting is that there are too many interesting zugzwangs and Rook goes to 7th vs 8th rank problems in this game (both in my analysis and in yours) that only engines get.

@jackwemedge thanks for adding this :-)
