English Opening: Symmetrical Variation, Rubinstein Variation

This line arises after the moves 1. c4 Nf6 2. Nc3 c5 3. g3 d5 4. cxd5 Nxd5 5. Bg2 Nc7. The Rubinstein Variation is characterized by Black's somewhat unusual knight retreat to c7 instead of more common squares like b6 or f6. This move aims to reinforce control over the central d5-square and prepares to support ...e5 breaks in the future.

From White's perspective, the setup with g3 and Bg2 signals a fianchettoed bishop aiming to exert long-range pressure on the center and queenside. White typically plays flexibly, focusing on controlling the center indirectly and preparing for central breakthroughs or queenside expansion.

Black's knight move to c7 is more positional and somewhat defensive, prioritizing solid control of central squares rather than immediate active play. Both sides engage in a strategic battle over central control, although direct central occupation is delayed.

In summary:

• Characteristic of ...Nc7: A repositioning move to support central control and prepare ...e5, avoiding early exchanges or confrontations.
• Attacking or Defensive: White's setup leans toward flexible, strategic play with potential for attacking chances; Black adopts a more cautious, defensive posture initially.
• Center Control: Both sides contend for influence over the center, but neither side immediately occupies it aggressively. The opening focuses on indirect control and preparation for future central breaks.
