I have this friend..
Sort:
I have this friend who is particularly good at chess, who I would very much enjoy beating. I know I could probably beat him in a blitz game (as he isn't really familiar with speed chess) I also figure that if I could increase my end game knowledge, I can increase my chances of besting him. I'm asking for any books, videos or principles that you end game wizards would recommend.
My suggestion to you is to learn the lessons in chess.com app itself
