    from: sacrifice::Square::G1,
    to: sacrifice::Square::F3,
    capture: None,
    promotion: None,
};
let new_node = game.add_node(game.root(), open_sicilian); // 2. Nf3 node
println!("{}", game); // exports the PGN string after 2. Nf3

// Take back the previous 2. Nf3 move
game.remove_node(new_node);
println!("{}", game);

// What if someone want to play 1. d4?
let queens_pawn = sacrifice::Move::Normal {
    role: sacrifice::Role::Pawn,
    from: sacrifice::Square::D2,
    to: sacrifice::Square::D4,
    capture: None,
    promotion: None,
};
let new_node = game.add_node(game.root(), queens_pawn); // 1. d4 node
println!("{}", game); // 1. e4 (1. d4) 1... c5

// Promote 1. d4
game.promote_variation(new_node);
println!("{}", game); // 1. d4 (1. e4 c5)

} ```
