Basic Chess Endings (anything but!) by GM Reuben Fine, revised by GM Pal Benko. It is easily the best chess book in my small collection. An encyclopaedic work that covers all important endings, but needs some dedication and "smart" work to benefit from. It trumps Silman's endgame course in that it covers everything in more detail, especially the "exceptions to the rule". I don't have Dvoretsky's manual, so can't compare to that.
The book itself is heavy and intimidating, and needs careful study to get use out of it. Fine and Benko present the material first by dividing it by pieces remaining (P only, N only, B only, R only, minors, R & minors, Q) then by number of pawns (e.g. K+3P v K+2P, K+R v K+2P) then by pawn position for the complex cases (one side has a passer, isolani or whatnot.)
The book examines "pure" base cases first (e.g. general method for R+P v R) then elaborates into how to convert/simplify to those in messes like R+manyP v R+fewerP. Throughout the book there are many "critical positions" where the outcome depends on the side to move and accurate play, and also many "exceptions to the rule" - problems, compositions and studies (the main reason why I prefer it to Silman, since you can learn the remote dangers to avoid, or the magic you can use to steal 1/2 points from others.) Most of my endgame knowledge comes from there, as well as the occasional puzzle I hijack threads with. :-P
Alright, I know this has been posted about a few million times over buuuuuut I want a true list. To that end, please don't:
I am a native English speaker with almost no skill with other languages. If possible, please speak of your experience with the book - don't worry about linking, I can find them myself.
I'll have a budget of around $150-200 (About 112-140ish euro). I am looking to purchase three books by the middle of next month and use the remaining money for other books that happen to be listed - though that would probably be a couple months MORE down the road.
Finally, I apologize for not searching around. I want as up to date information regarding this matter as possible. Also note that I already own a copy of My System: 21st Century Edition.
Thank you!
EDIT: Oh and if possible please explain what the book primarily covers.
EDIT2: My endgame is my weakest area. Just a heads up.
