Both sides have pawns in the centre (White on d4 and e4, Black on e5), and one pawn capture is available, so the structure has not settled yet. Development is level at two minor pieces each. It is White to move after 11 moves. Both kings have castled kingside, so play tends to shift to the centre and the opposite flank.
On the Ruy Lopez generally: One of the oldest and most classical openings. White develops rapidly and puts pressure on Black's center.
