Day 35: Rook endgames
Limited time today due to real life commitments, but I have taken a look at Mat's basic rook endgame puzzles, and did pretty badly at them

There's a webinar he has done on rook endgames. After I have finished watching the pawn endgames video I will watch that.
Sadly I am not likely to get to play more live games today, although maybe I will have time for a blitz game.
I took a bit more of a look at Mat's ebook on creating a plan. There is a position from a game in 2017 that he played where he evaluates all of the main aspects of the position and concludes "Black's position is slightly better". My first thought looking at the position is White is slightly better due to the strong bishop on g2. I entered the position into the computer to see what it thought and it evaluated +0.1 so neither side is really better here.



Day 34 continued: More endgames: Active King and Pawn Endgames
This is the other video on endgames from Mat BobulaVera Menchik was Women's World Champion from 1927 until 1944, when she was killed by a German air raid.
Mat blog post on pawn endgames is here and contains a few puzzles: https://www.chess.com/blog/MatBobula/how-good-are-you-at-pawn-endgames
Some of them are unintuitive but when you are thinking about the rules of opposition they become more logical.
This video explains the concepts Pawn's square, opposition, King and the pawn vs King, shouldering, triangulation, zugzwang, Pawn majority and the passed Pawn:
The video starts with the basics: opposition and promoting your pawn in King and Pawn v King endgames using the key squares.
12 minutes in it is King and 3 pawns versus King and 4 pawns.
16 minutes in is the 1st puzzle from the blog post.
