Recommened positiones

I want to start training calculation can someone give me some double edge positiones where i can try calculate the correct sequenec.Sorry for my spelling

Not a puzzle?

something that is not about themes more about calculateing

Wont start a new topic dug some more in to the matter can someone reccomened a book which gives a lot of variations and comments about the position now that i think about it chess informant is a good pick but i remeber i cant find,if there is commentery and lot of analysis its better.

What level book are you looking for?

the thing is i want a book where there are variations so i can set up the position on board spend thrity minuets calculateing variationes after that i will write down what i looked at and evaluate it and can compare it to the book

Ok black is a pice up  has the better pawn structer white no compensation i would evaluate it something like -/+.Black plan is to try to trade picecs gain more space with d5 and open up the position.

damn I set it up incorrect again, sorry the knight on c6 is not suppose to be there. 

black has the bishop pair and a better pawn structure cause white cant try to make a passed pawn on the queen side and a weakness on d6, but white has more space a half open file but his picecs are not cordinated so he cant attack an he does not have a black sqared bishop which makes the d6 pawn imune to attack.So black acording to me is better but no wining.

Based on that analysis, I'll go with http://www.amazon.com/Logical-Chess-Explained-Algebraic-Edition/dp/0713484640 for you

thanks for the reccomandation but the oposite that i was looking for.I am looking for a book where there a lot of diagrams variations and having comentary is a plus.I need it cause there i can find positions that i can train my calculation and evalate it in comparison with the book plus it will help with my concentraion.And it would help if you commented on my evaluation

I don't 100% understand what you are looking for. Are you looking for tactics, positional chess, game analysis, endgame knowledge. .I am looking for a book where there a lot of diagrams variations" Variations on what? Are you looking for full game analysis, game database with centain opening lines, a opening book, a book on strategical ideas. "I need it cause there i can find positions that i can train my calculation and evalate it in comparison with the book plus it will help with my concentraion" Are you looking for a tacitcs book. Based on your level I would say Susan Polgar's chess tactics for champions, Chess Tactics for Students  is 2 good books. 

I'll post the analysis for that position in the next comment, so you can see.

Let's evaluate the position then, white has 2 pawn chains, extra space in the centre, the only player with a open file. His pawns on the c-file are doubled, he possible break move is e5. He's knights are on the king side. Now to evaluate white's pieces before we get to black. Bishops are usually given evaluation according to their scope, so white's light squared bishop is worse then black's light squared bishop. The knight on f3 is about equal to the knight on f6. The knight on g3 should be slightly better then the bishop on e7. (all of that is according to scope, the amount of current squares the piece can move to). White's break move is e5, captures are Bxe6 (an example of this tactic being important would be Ng5-Bxe6). Now lets go over black. Black has the bishop pair. One more pawn in the centre then black, and more queen side space (cause of his furthest advanced C-pawn. He's break move is ...d5. Ok we broken down the position enough, although the position can be broken down even further, we can compare every endgame that could occure from this stuctture, and go through all the thinking techniques that can be followed, but to save time I'll skip that. Now white doesn't like that black has 2 bishops and a extra centre pawn and extra queen side space. Black doesn't like that white has the open file, extra centre space and king side pressure. Although this postion might be hard to evaluate with a engine, when it's broken down, the moves become easier to see. What do I like about myself, what do I not like about my opponent. I posted this position without saying who is to move, cause the side that moves feels better. Although if I were to evaluate more accurately, I would say white to move and play for equality, and black to move and play for a small advantage. A strong move for white after breaking down the position is 1. Ba6! If the light squared bishops are traded, black's best minor piece will be gone, and suddenly his open light squares will be pressured. Also 1. Ba6 gets out of the central threat ...d5 which was one of black's best moves. Now black cannot afford to trade the bishops, so 1. ...Bc6. White now has the choice to play Bb5, since a trade of bishops would make his position slightly more favourable, but white can be slightly more forcing. 2. Bb5 Bb7 3. e5, this is white's only break move, and now correctly timed, but the problem is, black can play 3. ...Bxf3 and although black might win a pawn, the position is very equal, and should break down into a draw. Now what if it was black to move. Black now knows, white wants to play Ba6 and trade bishops, so he plays the very strong move 1. ...a6! black now has a threat to win the bishop via b5-c4, so white needs to defend this threat by either moving his queen, or defending it. so 2. a4, but now black has the choice between 2 plans. 2. ...d5, which opens a file for black and opens his other bishops scope or the positional, anti-positional manuvuer, 2. ...Ng4-e5, where he will give himself doubled pawns for removing the strong knight on f3, almost trapping the g3 knight, and always maintaining 2 extra centre pawns, with a permanent advantage, possible winning idea is tradding all along the d-file and playing 2 bishops vs knight and bishop endgame. Anyway I hope I have said enough about that One chess position.

I think he would like to have positions where you can try to calculate a movement tree with some depth. He wants to see if he is able to calculate several paths without making mistakes, or train that ability. So he needs positions that have already several paths calculated so he can check his own answers later.

yup thats what i am looking for
