The Fried Liver Attack is one of chess's oldest and most exhilarating sacrifices, arising in the Two Knights Defense after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5. White immediately strikes with 6.Nxf7, sacrificing a knight to drag Black's king into the open. After 6...Kxf7 7.Qf3+ Ke6 8.Nc3, every White piece pours toward the stranded monarch while Black fights to defend the overworked knight on d5. It is a perfect attacking weapon for improving players: the plans are concrete, the initiative is instant, and a single inaccuracy can prove fatal for Black. If Black sidesteps with the solid 5...Na5, White simply grabs a pawn. Courageous, instructive, and devastating, the Fried Liver rewards sharp calculation.
Key ideas & plans
- White: after 6.Nxf7 Kxf7 7.Qf3+ Ke6, pile onto the overworked d5-knight with Nc3, then add d2-d4 and rooks to keep the king trapped in the center.
- White: treat the piece sacrifice as positional, not a quick raid - sustain the initiative and threats so Black can never castle or coordinate his pieces.
- White: key attacking levers are Qf3-e4, d2-d4 to rip open lines, Re1+ ideas, and a2-a3 to evict the defending knight from b4.
- Black: defend with ...Ncb4 (or ...Nce7) to over-protect d5, then ...c6 and a long king walk via ...Kd7-c7 toward queenside safety.
- Black: the cleanest practical antidote is 5...Na5, declining the sacrifice; White nets a pawn after 6.Bb5+ c6 7.dxc6 bxc6 8.Be2, but Black gets active development.
- White vs the Traxler (4...Bc5): avoid the wild 5.Nxf7 mess and choose 5.Bxf7+ Ke7 6.Bb3, keeping an extra pawn and the safer position.
Main lines
Fried Liver Attack: Main Line (Knight Sacrifice)
→The signature line: White sacrifices the knight on f7 to drag the king out, then uses Qf3+ and Nc3 to pile up on the pinned d5-knight and chase the exposed king. White gets a powerful attack for the piece.

- 8.Nc3
Fried Liver: 8...Nb4 (Critical Defense)
→Black's best try is 8...Nb4 hitting c2; White ignores material with a3 and recaptures on d5, keeping the king hunt alive while Black's knight is trapped on a1.

Fried Liver: 8...Ncb4 (g3 Setup)
→Black defends d5 with ...Ncb4; White centralizes with Qe4 keeping the d5-knight pinned, then opens lines with d4 to bring the bishop and rook into the attack on the stuck king.

Lolli Attack: 6.d4 (Quiet Alternative)
→The Lolli: instead of sacrificing at once, White inserts d4 and castles, then strikes on f7 with even more force as Black has committed to ...Be7. A sharper, modern refinement of the attack.

Knight Attack: 5...Na5 (Polerio Defense, Main)
→Black's soundest defense: 5...Na5 hits the bishop and declines the Fried Liver. White keeps the extra pawn with Bb5+ and dxc6, then retreats the knight to f3 with a small but lasting plus.

- 6.Bb5+c6
- 7.dxc6bxc6
- 8.Be2h6
- 9.Nf3
Knight Attack: 5...Na5 6.d3 (Modern Treatment)
→A solid modern path against 5...Na5: White returns the d5-pawn focus to development with d3, retreats the knight, and after the central tension resolves keeps a pleasant structure and the bishop pair traded off favorably.

Knight Attack: 5...Nxd5 6.Nxf7 Kxf7 7.Qf3+ Ke8 (Lolli Mate Threat)
→If Black tucks the king back to e8 instead of e6, White wins the knight on d5 outright with Bxd5, emerging a clean pawn up with the bishop pair and a continuing initiative.

Traxler Counterattack: 4...Bc5 5.Bxf7+ (Safe Main Line)
→Against the wild Traxler (4...Bc5), the safe practical recommendation is 5.Bxf7+, taking the pawn with check and dodging all of Black's sacrificial fireworks while keeping the extra pawn and a safe king.

Traxler: 5.Bxf7+ Ke7 6.Bd5 (Holding the Center)
→An alternative against the Traxler: after 5.Bxf7+ Ke7, White centralizes the bishop on d5 to clamp the center and the f7-square, then castles and plays d3 to keep a healthy extra pawn.

Fritz Defense: 5...Nd4 6.c3 (Main Line)
→The Fritz (5...Nd4) is sharp; White meets it with c3, retreats the bishop to f1, and after the forcing sequence emerges with an extra piece-for-pawns balance and a check on b5 that disrupts Black.

- 9.Bxb5+
Fritz Defense: 5...Nd4 6.c3 b5 7.Bf1 Nxd5 8.Ne4 (Knight Retreat)
→A safer handling of the Fritz: instead of grabbing on d4, White retreats the knight to e4 to blockade and untangle, then meets ...Qh4 with Ng3 to gain tempo and keep the position under control.

- 9.Ng3
Two Knights: 4...d5 5.exd5 b5 (Ulvestad Variation)
→The Ulvestad (5...b5) usually transposes to Fritz-type play; White retreats the bishop to f1, challenges the knight with c3, and again uses Bxb5+ to come out ahead in the resulting complications.

Two Knights: 5...Nxd5 6.Nxf7 Kxf7 7.Qf3+ Ke6 8.Nc3 Nce7 (Defense)
→Black defends d5 by adding ...Nce7; White opens with d4 to blast open the center and bring the dark-squared bishop and rooks to bear on Black's exposed king.

Two Knights: 4...Bc5 5.Bxf7+ Kf8 (King Stays Home)
→In the Traxler, if Black recaptures the bishop trade route with ...Kf8, White centralizes to d5, castles to safety, and consolidates the extra pawn while Black's king remains stuck on f8.

Fried Liver: 8...Nb4 9.Bb3 (Solid Sideline)
→A practical handling after 8...Nb4: White castles for safety, then breaks with d4 and dxe5 to open lines and keep the initiative against Black's displaced king even after it scurries toward d7.
