I think nothing can beat chess mentor in that area. It's simply the best. Other endgame resources I know of are chessimo (which is great for drilling if you know the theory) and chesstempo (which is great for general practice, but again, if you know theory).
Endgame Software

Endings of one rook and pawns are about the most common sort of endings arising on the chess board. Yet though they do occur so often, few have mastered them thoroughly. They are often of a very difficult nature, and sometimes while apparently very simple they are in reality extremely intricate. - Jose Capablanca

@Lucam92: Do you get the theory with the examples, or only examples? For example, say I want to practice K+R vs K+R+B, does it give you an explanation of what the theory behind K+R vs K+R+B is (ie. what squares to guard, what movements to make etc.), followed by 60 examples - or are you just given a sub heading called "K+R vs K+R+B" with 60 examples and no explanation?
Also, does it cover things like "Triangulation" and "Corresponding Squares"?
I've bought the Muller & Lamprecht's "Fundamental Chess Endings" book - but this is really a reference book (i.e. you only use it when you've reached a position in your game, rather than reading it for pleasure). I think I'll end up buying John Nunn's Endgame book at some point in the near future. I borrowed Silman's from a friend of mine a while back which was pretty interesting (it's broken down by rating, so it's really easy to use) - but Nunn's is cheaper ;-)

Theory is given inside the examples to back up the correct moves, but it is not general theory that could be aplied in other game (i.e "In this position Rg2 is not the correct move since it blocks ...")
Haven't found anything as Triangultion or Corresponding Squares but then again maybe they changed the name or I have not seen it.
Particulary I looking for a chess book that may help me with the middle game.
Hi,
As the title suggests I'm looking for some endgame software - preferably a program that teaches you the basics, and then tests/gives you examples on what you've just learnt.
I've recently bought CT Art 4, and I'm happy with the purchase, I was just wondering if the Convetka Endgame Trainer came with the theory, or if it is just like CT Art, whereby you go through endless examples with no theory involved?
Alternatively, if there is a better option that the Peshka/Convetka one, could someone let me know.
Cheers
