Ponziani Opening
3.c3 is the Ponziani Opening, a pawn move that prepares d4. If Black does nothing, White plays d4 and can recapture with the c-pawn, keeping two pawns in the center. The drawback is that c3 takes the natural square from the b1 knight and spends a tempo on a pawn, so Black usually strikes back right away.

Key moves
1. e4 e5 2. Nf3 Nc6 3. c3
- 3. c3The pawn supports d4 and opens the d1-a4 diagonal for the queen. It also leaves e4 without the help of a knight from c3, which is why Black's replies so often attack that pawn.
Counterattacking e4 with 3...Nf6
The knight hits e4 at once. After 4.d4 Black can take the pawn, and 5.d5 drives the c6 knight away with tempo. Black retreats to e7, and when White wins back the pawn on e5, the knight reroutes to g6 to challenge it.
Why Qa4 meets 3...d5
3...d5 opens the center before White is ready. With the d7 pawn gone, 4.Qa4 pins the c6 knight against the black king, so the knight cannot move without exposing the king. While it stays pinned, the knight is a less reliable guard for e5.
The main 3...Nf6 line
3... Nf6 4. d4 Nxe4 5. d5 Ne7 6. Nxe5 Ng6
Material is even and both sides have a knight in the middle of the board. Black's knight on g6 attacks the e5 knight, and White's queen can come to d4 to hit the knight on e4.

Questions
Where does White's queen's knight go in the Ponziani?
With c3 taken by a pawn, the knight usually comes out by d2 or a3. That slower route is part of the price White pays for the pawn center.
