If you want a closed position with White it is better not to play 1.e4. And if playing Ruy Lopez, you should probably play 4.Ba4 and not the Exchange Variation.
I you want a closed position with Black, it is important to acknowledge that it is not always possible to get. But you should not answer 1.e4 with 1...e5, where it is easy for White to open the position with a d4 anytime.
Is it possible to keep the Ruy Lopez Exchange Variation closed or to make it become closed, or are both sides forced to keep the Ruy Lopez Exchange variation constantly open?
Is it also possible to keep the Ruy Lopez Exchange Variation semi-closed?
