Knowing when to change pawn structure is one of the most important skills in positional play. Let's see a simple but instructive example: How would you play as black?

… dxe5

dxe5. Nxc3

looks promising. 

if Rxa8 then Nxe2+ appears to win material

else if bxc3 white’s queenside pawns are both Isolated and weak.

you take on c3, pawn takes, take on e4, Q takes, push d5 closing position when you have the good B, Q goes back and you could pressure c pawn now or outpost N on c4.

in the line I suggested, they could avoid closing the position by taking to d6 after you take on e4, but in this case they end up with and IQP with very little activity

dxe5 White can play an intermediate Bxd5, and then we can't create such a favorable structure, but his move looks decent.

It also looks decent, but in these structures with a white pawn on e5 white will have counterplay on the kingside with moves like Qg4/Qf3-g4.

that’s true. I missed Nxc3, bxc3, Bxe4, Qxe4, dxe5! Qxe5 and black as a bad IQP
