Current setup

Move ideas

  1. 1.c4

    Controls d5 from the flank without occupying the center immediately.

    Idea: Pressure the center from the side and keep the pawn structure flexible.

  2. 1Nf6

    Develops the knight to f6, bringing it into the game.

    Idea: Improve piece coordination and clear the back rank for castling and the rooks.

  3. 2.b4

    Advances the b-pawn to gain queenside space and control new squares.

    Idea: Prepare a fianchetto or discourage the opponent’s expansion on that wing.
