Turning a pawn into a perfect centre.

If you remember one thing
c3 and d4 are not two separate ideas; they are the single plan that justifies the gambit.
What c3 actually does
c3 attacks the bishop, supports d4, and opens the queen's path to b3 and a4. It looks like a quiet pawn move, but it is the key that unlocks the whole position.
The d4 break
d4 opens the centre while Black's kingside is still undeveloped. It is not played to win a pawn; it is played to open diagonals toward the black king.
- —After ...Ba5, castle before recapturing to avoid a pin.
- —After ...Bc5, cxd4 comes with tempo against the bishop.
- —After ...Be7, White has a free hand and can choose d4 or b5.
Why development comes first
A central break is only strong if your pieces can use the open lines. If the f1-rook is still at home and the king is in the centre, d4 is often a blunder. Develop, castle, then strike.
Typical mistakes
Recapturing too early, playing d4 without enough support, and ignoring the pin on c3 are the three ways the break backfires. Patience is usually the strongest move.

Transcript
Every line of the Evans Gambit leads to the same question: can White play c3 and d4? If the answer is yes, the gambit has succeeded. If the answer is no, White is just down a pawn.
The move c3 does three jobs at once. It attacks the bishop, it prepares d4, and it opens the b1-h7 diagonal for the queen. That is a huge amount of work for one pawn move.
