Knight vs Rook with pawns majority

Hi dudes, need some help with the strategy of this kind of endgame.  

I would like some article or book about the theme to use in a corresponde game i am losing.

Here the main issue: what is the correct play for both sides?

There is a complete study case of the this theme?

In time: the pawn structure is perfect for both sides, so what  i want know is how the winning side must play to convert his majority (2x1) using his rook and how the losing side must play to avoid it using his Knight.

Obviously I know it is a very difficult play to the losing side, but is also a very good opportunity of learnship.

Thanks anyway.

If this is an ongoing game, I don't think anyone is permitted to offer help or advice until after the game ends. It might, but I am not certain, include advice on books/articles to read. It could also be why no one has responded.

chessarx it is very sad if the reason of people doenst answer is that since players are allowed to use books/articles and databases in correspondence games.

Anfortunately the page with the rules in chess.com doenst works

http://support.chess.com/Knowledgebase/List/Index/3/online-chess-rules-and-questions

But here  are the rules in another  site of online chess (queenalice.com) where I play:

• "You cannot use a computer or computer program to evaluate or analyze a game. However, you may use computers for record keeping. It is also allowed to consult chess books and opening databases."

Using books and databases is different than people giving you advice.

When you use books and databases (ony in correspondence or "online" chess), you are doing the work yourself. Telling you where to find the info is doing the work for you.

This is a common way  of interpreting the rules that the vast majority of people accept. Only a few don't interpret the rule like this, usually those that want advice.

No, not in any form of correspondence chess can you ask people for advice on one of your games.  

You ask for advice or help if you want know what  move to do or how you should play. 

Ask about a good book or website to study something is not the same.

E.g

You are playing the positional theme of 2 bishops against Knight and bishop. If you ask

HOW or WHAT should I play know to win this game?

that is wrong

But you  ask

Do you know a good book to study this?

That is totally normal since you will have to study it anyway.

Just think on it

if you think is wrong ask about some book while playing a online game and instead you search by yourself what is a good book, what would you do?

go to google and put

Best book about...

And what will you see?

The opinion of other people anyway!

Or do you really think that DO THE JOB and THE HARD PART OF STUDY CHESS is...

SEARCH FOR THE TITLE OF THE BOOK!?

well...ok then. I respect it.

OH i find a good book, let me see how better I am now because that!
