Guys....where do I study rook endgames? Someone please help me out with some resources(some books or some courses by someone and etc)
My advice would be to do the following.
1. Make sure you know all the Rook Endgame lessons on ChessMood lectures
2. Go through the Rook ENdgames sections of 100 Endgames you Must Know by Jesus De La Villa
Then either study Secrets of Rook Endgames by John Nunn - Excellent book or get A Practical Guide to Rook Endgames by Nicolay Minev and Yasser Seirawan. Kasparov once said this was his favourite book.
After that I'd study some classical rook endgames in simple positions. For example where you have R +3 versus R+3 on the K side and an extra pawn on the Q side or R + 4 versus R and 3 on the K side and learn how the GMs played these positions. There are lots of good examples. When you find good ones add them to your Rook Endgame database for review later.
Then study some more complex Rook endgames. Create a Rook Endgame database and add the games for you to review. For example, some of the ones in my database to get you started include:
1. Gurgenidze - Radev Tblisi 1971
2. Karpov - Hort Waddinxveen 1979
3. Polugaevsky - Evans Siegen 1970 (active defense)
4. Zhidkov - Razuvaev USSR 1971 (mating threats)
5. Estrin-Pytel Albena 1973 (competing sets of passed pawns)
6.Ivanov-Bonchev Bulgaria 1974 (complicated by opponents strong pawn)
And I haven't even mentioned the many nice rook endgames of Rubinstein, Capablanca and Alekhine that are very much worth a study.
Hope that helps. And good luck.
At 1339 you just need to know the basic positions; even 100 endgames is overkill. IM Bartholomew's series of fundamental endgames on YouTube which demonstrates the basic positions is more than enough. Philidor, Lucena and keeping one's rook active is probably about it. 1300s lose games mostly to blunders, poor tactical skill, really basic endgames, the knight and playing passive risk adverse (or too caveman on the other extreme). When talking about games between 2000+ players rook endgame skill is more a factor.
