This is a symmetrical four pawns center formation - White has pawns on d4 and e3 and Black has pawns on d5 and e6.
In practice, however, this formation doesn't lead to many chances of full-bodied conflict, since an automatic exchange of the major pieces typically follows on the one open file.

[17... Rd7]
If both sides occupy the same open file, then neither should exchange Rs but should leave the exchange to the opponent so that the recapturing R or Q commands the open file.

If in a bad position in the middlegame, the retention of the Q will at least offer chances of perpetual in the ending, for a lone Q can often force the draw in this manner.

In balanced positions, when neither side has any direct threats or concrete plan, it is necessary either to relocate your worst placed piece to its best square, or to exchange it off.

Having said that, the correct moves, according to Rybka, are Ke8, a6 or Bd8.
