Closed pawn position question

As any side, if my opponent sets up a closed pawn structure constantly expanding his pawns alternating on ranks 4 3 4 3 4 3 or 7 6 7 6 7 6, what should I do with my pawns, minor pieces and major pieces... If I try to expand on my own pawns trying to hurt his position I would end up opening the king side which is usually the most often castling side. I'm very clueless on what to do and even if my opponent is opening up his king I can't seem to exploit it due to his pawns in the closed position. Thanks in advance.

I'm not sure what you mean exactly by "constantly expanding his pawns on alternating ranks"

Two things to know though.

Every pawn move, even good ones, permanently weaken the squares they leave behind.  If your opponent advances his pawns too far like this, it will leave behind a lot of territory and after a file is opened by exchanging pawns your infiltration will really hurt him.

The 2nd thing is, if pawns are set up like this

Then the dark squares are very weak.  Now cut this position in half and look at the white and black side separately.  What white has done is not as bad as black.  White is still able to have the base of his pawn chain (the weak point) on his 2nd rank which is close to home and usually easily defended.  White can still move some pawns to dark squares to help himself out. 

In black's case not only has he left a lot of territory behind (weakened squares) but his dark squares are like swiss cheese.  in a real game white would not mirror this, but would facilitate some pawn trades and black would be weaker due to his loose pawns and weakened squares.

So there's no special killer set of moves.  It's still chess... pay attention to the threats your opponent's last move did and all that.  And as you open lines and begin to attack, you'll just automatically have a better position.

Great answer Waffle. 

Aside from a weak/strong approach, you can simply "break" this kind of position simply by doing what a guy should normally be doing strategically, which is developing central strength and pushing up the middle.   If all your opponent is doing is setting up some kind of pawn barricade, you can get your knights out, your central pawns out, and maybe get your rooks doubled, and then just open the position whenever you want. 

I put in a possible set of moves for white - simply developing the central pawns and getting 0-0 with an aim to putting a rook on the e file.   After 7 or 8 turns, you can legitimately say white is for choice - black has organic weaknesses and no piece mobility, white has pressure up e and the more things open up, the better it is for white, and there's no current danger to white's kingside.  

White could drop a piece in the "hole" on e5, and just leave it there forever and ever, and just choke black to death with that kind of square-control strategy, or he could blow things open and use the fact that black's moves are essentially a waste of time where white's moves have gotten pieces into play.  

PS  Study the games and ideas of Nimzowitch - he was a master of taking closed positions and breaking them, and of keeping things advantageously closed when he wanted to and just doing a sort of boa-constrictor routine on his opponents. 

Ok thanks guys, I appreciate the help, it actually helped.

A pawn attack on the flank is always answered by an attack in the centre, when u controll the centre, its way easyer to controll the flanks. Therefore pawn attacks are almost always played in positions where the centre is closed after the opening such as the KID etc. but most of all in the closed French defence. And indeed i also have "My System" by Nimzowitch it realy is a great book.
