Open Games as Black

1.e4 e5

Meet 1.e4 with 1...e5 and know exactly what to do next: defend e5 with the knight, develop the bishop to c5, castle. Then the specific answers to what beginners actually see — the Scholar's-mate try, the early Bc4, the King's Gambit, the Scotch and the Ruy Lopez.

Spar this opening

Your setup

  • Knightc6
  • Knightf6 / e7
  • Bishopc5 / e7 / b4 / b6
  • Bishope6 / g4 / d7
  • Pawnse5 d6
  • CastleO-O

Nc6 before Bc5. Knight first: it defends e5, so the bishop can come out without dropping the pawn to Nxe5.

Ideas

Defend e5 with the knight first

After 2.Nf3 the pawn is attacked. ...Nc6 defends it and develops — always this move first.

Every other move either drops the pawn (…Bc5? Nxe5) or defends it badly (…d6 locks the bishop, …f6 weakens the king, …Qe7 blocks the bishop). ...Nc6 does the job and gets a piece out.

The Scholar's-mate try: Qh5 or Qf3

...Nc6 (defends e5). When Bc4 comes, ...g6 kicks the queen. Then ...Nf6. Never ...Nf6 while the queen and bishop both eye f7.

The queen alone threatens nothing but your e5-pawn; ...Nc6 covers it. Once Bc4 joins in, f7 is the target — ...g6 forces the queen off the diagonal and ...Nf6 blocks the f-file. Three calm moves and you're a tempo ahead with their queen exposed.

The early Bc4: hit e4 with ...Nf6

2.Bc4 Nf6 — the bishop can't take on f7 profitably (…Kxf7 and you're a piece up).

Bxf7+ is a bishop for a pawn; your king walks back later. Meanwhile ...Nf6 attacks e4. Only don't take on e4 after Nc3 or Qe2 — those set traps; develop with ...Nc6 instead.

Against the Italian: mirror with ...Bc5

3.Bc4 Bc5 — the same setup they have. A knight jump to g5 is just a free piece (…Qxg5).

The Two Knights (…Nf6) invites Ng5 and the Fried Liver — a theory fight you don't need. ...Bc5 is calm: ...Nf6, ...d6, castle, and the position is level.

Against the Ruy Lopez: ...a6

3.Bb5 a6 — ask the bishop. Bxc6 dxc6 is fine (Nxe5? Qd4! regains the pawn); Ba4 Nf6 and develop.

Bb5 pressures the knight that defends e5. ...a6 forces White to decide: trade (and give you the bishop pair) or retreat (and lose a tempo to ...b5 later). Then ...Nf6, ...Be7, ...b5, ...d6, castle — but never castle before ...b5 and ...d6 while Re1 is in (the Tarrasch trap).

Against the Scotch: take, then ...Bc5

3.d4 exd4 4.Nxd4 Bc5 — the bishop hits the knight and eyes f2.

Taking on d4 is forced (or e5 falls). After Nxd4 the knight is attacked; ...Bc5 develops with a threat. If c3 instead (a gambit), ...d5 declines it calmly.

The fork trick: ...Nxe4 then ...d5

With knights on c3 and f3 and a bishop on c4, ...Nxe4! Nxe4 d5 wins the piece back with a better centre.

...d5 forks the bishop and the knight. Whatever White does you regain the piece, get rid of their Italian bishop, and take the centre. Free equality — and a lesson in forks.

Against the King's Gambit: decline with ...Bc5

2.f4 Bc5 — White can't castle, and fxe5?? loses to ...Qh4+.

Taking on f4 is real theory; declining isn't. ...Bc5 points at g1, ...d6 holds e5, and if White ever takes on e5, ...Qh4+ is crushing.

When the book runs out

Knights out, bishop to c5 or e7, castle, then ...d6 or ...d5 depending on how much of the centre you can hold.

Open games reward development speed and king safety. Get everything out, castle, and only then look for tactics — most of your opponents won't manage that.

The structure

The mirrored Italian: both sides developed and castled. Your freeing idea is ...d5, prepared by ...a6, ...Ba7 and ...Re8.

Traps

Scholar's mate (don't fall for it)
e4 e5 Qh5 Nc6 Bc4 Nf6 Qxf7#

The tell: Queen on h5 (or f3) and bishop on c4, both aimed at f7.

Two attackers on f7, one defender. ...Nf6 attacks the queen but doesn't stop the mate. ...g6 first — then ...Nf6.

The fork trick
e4 e5 Nf3 Nc6 Nc3 Nf6 Bc4 Nxe4 Nxe4 d5

The tell: White has knights on c3 and f3 and puts the bishop on c4.

...Nxe4 Nxe4 d5 forks bishop and knight: you regain the piece, remove their Italian bishop and take the centre.

The free knight on g5
e4 e5 Nf3 Nc6 Bc4 Bc5 Ng5 Qxg5

The tell: White's knight lunges to g5 while your queen still sees the square.

With ...Bc5 (not ...Nf6) the knight on g5 is defended by nothing. Just take it.

King's Gambit: fxe5?? Qh4+
e4 e5 f4 Bc5 fxe5 Qh4+ g3 Qxe4+ Qe2 Qxh1

The tell: You declined with ...Bc5 and White takes on e5 anyway.

fxe5 opens the e1–h4 diagonal. ...Qh4+ g3 Qxe4+ wins the e4-pawn with check and then the rook on h1 (Ke2 instead walks into ...Qxe4+ too).

The Tarrasch trap (don't fall for it)
e4 e5 Nf3 Nc6 Bb5 a6 Ba4 Nf6 O-O Be7 Re1 O-O Bxc6 dxc6 Nxe5 Qd4 Nf3 Qxe4 Rxe4

The tell: In the Ruy Lopez, White plays Re1 before you've played ...b5 and ...d6.

Castling here lets Bxc6 dxc6 Nxe5 win a pawn: the natural ...Qd4 Nf3 Qxe4 loses the queen to Rxe4. Play ...b5 and ...d6 first, then castle.

Model games

Italian, mirrored
e4 e5 Nf3 Nc6 Bc4 Bc5 c3 Nf6 d3 d6 O-O O-O

Knight defends e5, bishop to c5, knight to f6, ...d6, castle — the same calm build-up your opponent is doing.

Ruy Lopez, the safe way
e4 e5 Nf3 Nc6 Bb5 a6 Ba4 Nf6 O-O Be7 Re1 b5 Bb3 d6 c3 O-O

...a6 asks the bishop; ...b5 and ...d6 come BEFORE castling once Re1 is in.

Scotch
e4 e5 Nf3 Nc6 d4 exd4 Nxd4 Bc5 Be3 Qf6 c3 Nge7

Take on d4, hit the knight with ...Bc5, then ...Qf6 and the knight to e7.

Wayward Queen, refuted
e4 e5 Qh5 Nc6 Bc4 g6 Qf3 Nf6 Ne2 Bg7

...Nc6, ...g6, ...Nf6: the Scholar's-mate try leaves White's queen exposed and you ahead in development.

The fork trick
e4 e5 Nf3 Nc6 Nc3 Nf6 Bc4 Nxe4 Nxe4 d5 Bd3 dxe4 Bxe4 Bd6

...Nxe4 and ...d5 regain the piece with the centre; equal and comfortable.

How the coach grades a move

Every move you play gets one of six grades, from the engine’s view of the position, with the book’s verdict taking over when it is harsher. The sentence beside it is always the reason. Tap it for what the move did, why this opening wants it, and whether anything was better.

Best
Nothing better was available.
Good
Within a few percent of best. Noise at this depth.
Playable
A small real gap. The better move is named, play goes on.
Inaccuracy
Seven to twelve points of winning chances. The game stops to show you.
Mistake
Twelve or more, or a move the book warns against, or a broken order rule.
Blunder
Twenty-five or more. Usually material.
