The current FEN is: `rnbqkbnr/ppp1pppp/8/3p4/8/5N2/PPPPPPPP/RNBQKB1R w KQkq - 0 2 moves d2d4 g8f6`

The Symmetrical Variation of the Queen's Pawn Opening, normally, :

1. d4 d5

This is the starting position of the Queen's Pawn Opening. White and Black have both advanced their d-pawns two squares. This symmetrical pawn structure leads to the 'Symmetrical Variation'.

2. c4 c5

Both sides continue to mirror each other's moves to maintain the symmetry. Now White and Black have both placed their c-pawns in the center, contesting the d4 and d5 squares. This central tension leads to dynamic play with chances for both sides.

3. Nf3 Nf6

The knights are developed to add more pressure to the center. The e4 and e5 squares become potential outposts for the knights. Again, White and Black mirror each other to keep the symmetrical structure.

4. Nc3

White develops the c1-knight to add to the pressure on d5. This is a common follow-up to 3...Nf6, putting pressure on Black's central d5-pawn. Black has a few options to respond:

- 4...Nc6: Developing the c8-knight to contest the c4-square and put pressure on d4. This leads to very dynamic positions with chances for both sides to attack the enemy king.

- 4...Bf5: Developing the c8-bishop to pin the knight on c3 and put pressure on the e4-square. This leads to unbalanced positions with chances for White to gain a space advantage.

- 4...a6: A more passive move to prepare ...b5, kicking the knight on c3. This allows Black to avoid the pin but concedes some tempo and space to White.

As you can see, despite the symmetrical opening, the positions can become quite dynamic and unsymmetrical later on with both sides having opportunities to fight for the initiative. The specific move orders and follow-up strategies for both sides can lead to a variety of middlegame structures and positions. Let me know if you would like more details on any specific lines or variations.
