Ruy Lopez: Schliemann Defence
Also known as Schliemann, Jaenisch Gambit
1.e4 e5 2.Nf3 Nc6 3.Bb5 f5
The Schliemann (or Jaenisch Gambit) meets the Ruy Lopez with the daring 3...f5, throwing a pawn at White's centre to grab the initiative. It is sharp, double-edged and rich in tactics - a fighting weapon for Black players who relish chaos over a quiet middlegame.

What it does
After 1.e4 e5 2.Nf3 Nc6 3.Bb5, Black plays 3...f5, immediately attacking White's e4-pawn instead of developing quietly. The idea is to blow open the centre and the f-file, generating active piece play and attacking chances against White's king. White is offered a pawn or a complex structure; in return Black accepts a slightly loose kingside and must play accurately. It is a true gambit in spirit, prizing initiative over material and solidity.
When to use it
Reach for the Schliemann when you want to seize the initiative against the Ruy Lopez and steer the game into sharp, tactical waters rather than the slow manoeuvring of the main lines. It suits aggressive players who enjoy concrete calculation and are willing to study forcing variations. Because the theory is exacting and one slip can be fatal, it rewards preparation - ideal as a surprise weapon or a pet line you know deeply.
Why it works
By hitting e4 at move three, Black seizes the agenda before White finishes the usual Ruy Lopez set-up, forcing White to react to concrete threats. Lines open quickly along the f-file and in the centre, where Black's pieces - the queen, the f8-bishop and a knight to f6 - find active squares and target the white king. The pawn sacrifice buys time and lines; if White grabs material greedily or defends imprecisely, Black's lead in initiative can become a lasting attack.
Key ideas
- Strike at e4 with ...f5 to open lines and seize the initiative.
- Treat it as a gambit: trade a pawn for fast, active piece play.
- The half-open f-file aims pressure at White's kingside.
- ...Qg5 often jumps out with tempo, eyeing c6 and g2.
- Accept a looser king position as the price of activity.
- Deep, forcing theory - accurate calculation is essential.
Watch out
As White, do not grab greedily: after 4.Nc3 fxe4 5.Nxe4 d5 6.Nxe5 dxe4 7.Nxc6 Qg5, Black's queen leaps to g5 hitting the loose knight on c6 and the g2-pawn, and careless play hands Black a fierce attack. As Black, the 4.d4 and 4.exf5 tries have their own tactics - learn the safe recaptures first.
