In this structure we will look at a position where everything was equal, except that white had more active bishops. Black then went for a premature kingside attack, which ruined his coordination and white was able to get a good advantage.

Positional subtlety
There is tension between the rooks, both sides will look to control the open files, so it’s common to see rooks on c1, e1, c8 and e8.

But when one side has given up control of a file with an outpost or key square., then the other side should give up a file, to maintain control over the outpost or key square.
In the position below, the black rooks are no longer fighting for the e5-outpost. So white gives up on the c-file so that his e1-rook can remain focused on the e5-square.
