Ruy Lopez: Exchange Variation, Keres Variation

This line arises after the moves 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 dxc6 5. Nc3. In this variation, White exchanges the bishop for Black's knight on c6 early, doubling Black's c-pawns and aiming to exploit structural weaknesses.

Characteristic of 5. Nc3: This move develops a knight to a natural square, supports control of the center, and prepares to increase pressure on Black's pawn structure. Unlike the more common 5. O-O, it keeps options flexible and often leads to rich positional play.

From White's perspective, this variation is somewhat positional and strategic, focusing on exerting pressure on Black's slightly compromised pawn structure rather than launching an immediate attack. Black, on the other hand, aims to use the bishop pair and dynamic pawn structure to counterattack.

Regarding the center, White maintains a solid presence with the pawn on e4 and knights developed towards central squares, so this opening does focus on controlling the center, though not with aggressive pawn pushes but through piece pressure and structural considerations.
