Positional chess.

Can someone try to explain positional chess to me?. I am so confused by it, but I don't think that I can get to much better unless I start to figure it out.

Could You give examples of it in action? What is it exactly?

It's about basic principles such as weak squares, good bishop vs bad bishop, control of files, control of the 7th and 8th rank by a rook or queen, doubled pawns... if you would like to learn more about it, nimzowitsch has a great book called 'my system' where he explains these concepts chapter by chapter

If you google "positional chess" you will find out all you need to know about it. When I was looking, I happened to find a chess web site called that is a question and answer forum for chess. Pretty cool site...I book marked it. :]

It is chess, with some principles and thought put into it, like

improving your pieces
pawn structures, pawn islands, doubled/tripled pawns
stopping your opponents plan/countering it
Punishing mistakes and blunders
weak squares/important squares
diagonals, open files/semi-open files.

Playing aggresively, usually neglects most of these, but that doesn't mean it's bad to play aggresively.

A piece that doesn't "actively" do anything or influence any squares, like rooks being better on open lines, than closed, knights being better (usually) in your opponents half of the board, bishops being better on open diagonals, constricting movement, and such.

Okay. Would it be too inconvenient for you to give me an example?

I always point out that Morphy played great combinations but had a bad pawn structure. (Although many say he was so good because he understood the positional aspect of the game.) Chess is a zero sum game or, as Fischer said, you have to give something to get something.

@ChessMathNerd is a good--not the best--video explaining badly placed pieces.
