So you want to actually play the Evans Gambit, not just admire it from a distance. Great — and the good news is the main line is wonderfully logical. Every move has a clear job: chase the bishop, win a tempo, build the center, then castle and attack. We’ll walk the most important line — the Evans Gambit Accepted with 5…Ba5 — move by move, explaining the why behind each one, then point you to where the road branches.

The line we’re learning: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Ba5 6.d4 exd4 7.O-O This is the classic Evans Gambit Accepted, reaching White’s coiled-spring attacking tabiya.

Move by move

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 — the Italian Game

Both sides develop naturally: pawns stake the center, knights come out, and both bishops slide to their best diagonals (c4 and c5), each eyeing the other’s weak f-pawn. This is the Giuoco Piano starting position — the calm, classical Italian. The fireworks haven’t started… yet.

4.b4 — the gambit!

Here it is. White flings the b-pawn forward, offering it to the c5-bishop. The point isn’t the pawn — it’s time. Whatever the bishop does next, White will follow with c3 (hitting it again) and then d4, building a huge center for free.

The Evans Gambit after 4.b4 — the pawn is on offer, and the bishop on c5 is being kicked.

4…Bxb4 — accepting the gambit

Black takes. Why not? It’s a free pawn, and the classical view is “accept a gambit, then give it back later if you must.” Now White has to prove the compensation is real — which is exactly what the next moves do.

5.c3 — kicking the bishop, building the center

A two-for-one move. 5.c3 attacks the b4-bishop again, forcing it to move a second time, and it prepares the big central push d4. Black’s bishop has now been chased twice while White hasn’t wasted a thing — that’s the tempo the gambit pawn bought.

5…Ba5 — the main retreat

The bishop slides back to a5, staying on the active a5–e1 diagonal and keeping an eye on White’s queenside. (It can also go to e7 or back to c5 — see the variations page — but a5 is the classical main line.)

After 5...Ba5 — the bishop pins itself to the queenside while White prepares to seize the center.

6.d4 — the center explodes

There it is — the whole reason for the pawn sacrifice. 6.d4 strikes in the middle, opening lines for the c4-bishop and the rooks. Suddenly White’s pieces have room, and Black’s are still mostly at home.

6…exd4 — Black grabs another pawn

Black takes again. Now Black is technically two pawns up — but watch how little that matters in a second. White is about to castle and unleash everything.

7.O-O — castle and attack

White tucks the king away and, just as importantly, puts the rook on f1, where it supports a future f-file assault and the central tension. This is the Evans tabiya: White is two pawns down on the scoreboard, but has a mobile center, the bishop drilling at f7, a rook on f1, and a big development lead.

The Evans tabiya after 7.O-O — material down, but White's pieces are coiled and pointed at Black's king.

The tabiya — and where it branches

That move-7 position is a genuine tabiya that thousands of romantic-era games reached. White’s lead in development and central control are the compensation for the pawns. The plan from here is direct: regain the d4-pawn with cxd4 (or leave it and develop with Qb3, Ba3, Nbd2), then attack down the center and at f7.

From the crossroads earlier, Black has other tries instead of 5…Ba5:

5…Be7 — the Hein / quiet retreat, planning a quick …Na5 to trade White’s c4-bishop and return the pawn for safety.
5…Bc5 — straight back, daring White to prove the center is worth it after 6.d4 exd4 7.cxd4.
5…dxc3 — the Compromised Defense, where Black greedily grabs even more material and White gets a ferocious attack.

And on move 4, Black doesn’t have to take at all:

4…Bb6 — the Evans Gambit Declined, sidestepping the whole fight.

Don’t feel you have to memorize every branch. The thread running through all of them is the same: White spends pawns to chase the bishop, take the center, and develop with tempo. Once you internalize that, the moves stop feeling like memorization and start feeling like a plan.

FAQ

What’s the main line of the Evans Gambit? 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Ba5 6.d4 exd4 7.O-O — the Evans Gambit Accepted, reaching White’s classic attacking tabiya.

Why does White play 5.c3? It hits the bishop a second time (winning a tempo) and prepares the central break d4. It’s the move that turns the gambited pawn into real compensation.

Is 5…Ba5 the only retreat for Black? No — 5…Be7 and 5…Bc5 are both fully playable, and the greedy 5…dxc3 leads to the sharp Compromised Defense. We cover them all on the variations page.

Do I have to memorize all these moves? Understand the ideas — chase the bishop, play c3 and d4, castle, attack f7 — and the moves follow naturally. The exact order matters most in the sharpest lines.
