How to play closed positions?

Try to create pawnbreaks to open the position and try to attack with your knights they are the best piece in closed positions

Is the title not exciting enough?
Is the first post too long?
The topic is too broad. A whole book could be written about this.
Basically, if the position is closed and you have less space, look to break up the pawnchain from one side (or both).
It would be more useful if you showed us a game.

Closed games are a very different beast to the sudden tactics that flare up in open games. Sometimes your plans are slower, and you're looking to get your pieces into better squares. When there are lots of pawns still on the board, particularly when they start to form interlocked walls, your Knights are more likely to be the hero piece for you. Look for outposts for them, where they will just sit there, worrying your opponent and limiting their movement by their very presence. It's not so much looking for an immediate knock out blow, but just looking for how to keep building the pressure (meaning, limiting what your opponent can do). Also, find squares for your Bishops so they point towards the enemy King. Even if they can't get there due to all the pawns in the way, if you find a way to break up those pawns, then your Bishops, currently limited, are at least already where they need to be. Finally, if you've got everything pointed at the enemy King, who seems smug and safe behind their pawns but their pieces are busy trying to do something on the other side of the board and most importantly, on the other side of the wall of pawns so they're sort of cut off from coming home, don't be afraid to sack stuff to rip apart that pawn shelter - just make sure after you ditch a Bishop or Knight, that you've still got some heavy artillery ready to leap in faster than your opponent's pieces can come to the rescue. There are tactics in closed positions, you just have to set them up during the quiet period before the storm. Here's an old game of mine against the French Defence which often results in fairly closed positions. I was playing around with a weird line that isn't very good but was a lot of fun. (I was playing around with an early P-KB4 - meaning f4 - sorry I grew up with descriptive and still think that way). Anyway, it's got a few of the ideas, the pawns lock up, Black's pieces are cut off from getting back to the King, and my pieces all have easy access. Sadly, I missed much prettier mates, but worse saw a mate and just before playing it thought I saw it's also "Mate by Pawn", which it wasn't, and it sort of turns into the Benny Hill Show (which may mean nothing to you, but if it does you may be familiar with descriptive after all! )

I can’t find any plans or tactics since my pieces are too cramped behind my pawns. Sometimes I try to shuffle my pieces around and trade some flank pawns, but that takes a few moves which my opponents can use to set up an attack.
Is there anything better to do in closed positions?
