The opening is named after Giambattista Lolli, an 18th-century Italian master and chess theorist. The general view is that it gives White a promising attack and real dynamic compensation.
The Lolli Attack in one minute
- What it is: an aggressive try against the Two Knights Defense, reached after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5?! 6.d4. It is a close cousin of the Fried Liver that prepares the f7 sacrifice instead of playing it at once.
- The idea: open the center with 6.d4, then strike with Nxf7 and Qf3+, dragging the Black king into the open while the rook swings to e1.
- Black's main tries: 6...exd4, 6...Nxd4 and the slow 6...Be7 (or 6...Bb4+). White keeps a clear edge against all of them with accurate play.
- Who should play it: Italian Game players who want to punish 5...Nxd5?! and enjoy sharp, attacking chess. White scores around 57% from this position.
- Lolli or Fried Liver? Same target (f7), different move order. Playing 6.d4 first is more flexible and a fine surprise against opponents who only prepared the Fried Liver.
White's scoring from the diagram position tells the same story numbers usually tell about gambits below master level: the side with the attack wins far more than it has any theoretical right to.

Key ideas in the Lolli Attack: open the center with 6.d4, then strike f7
The Lolli Attack is as sound and as deadly as the Fried Liver, and it is tactically justified. White delays and prepares the thematic knight sacrifice on f7 by opening the central files with 6.d4. The idea is to put Black under immediate pressure in a position that is genuinely hard to defend, with the king stuck in the center after Nxf7 and Qf3+. One small slip can quickly become a losing mistake, and the sheer effort of having to find the only defensive move, move after move, often leads to oversights and blunders.
The position almost never appears between two masters, because strong players sidestep the whole line by avoiding the dubious 5...Nxd5?! and choosing 5...Na5 instead. For Italian Game players, though, knowing how to punish 5...Nxd5?! in the Two Knights Defense pays off again and again at club level.
Lolli Attack vs Fried Liver Attack: what is the difference?
Both attacks branch off the same position after 5...Nxd5?! and both aim at f7, so they are easy to mix up. The difference is the move order, and that single tempo changes the character of the fight.
The Fried Liver Attack sacrifices immediately with 6.Nxf7, committing White to a forcing attack at once. The Lolli Attack plays 6.d4 first, opening the center and only then sacrificing on f7, usually with the rook already heading for e1. The Fried Liver is the punch; the Lolli is the same punch thrown after one extra step to put the body behind it.
| Lolli Attack (6.d4) | Fried Liver Attack (6.Nxf7) | |
|---|---|---|
| First move | 6.d4 opens lines before sacrificing | 6.Nxf7 sacrifices straight away |
| Type of sacrifice | Pawn now, knight often later (or never) | Knight immediately |
| Character | Flexible, less forcing, more pieces join in | Sharp and forcing from move six |
| Best suited to | Players who like to attack with full development | Players who want an immediate kill |
In practice the Lolli is a dangerous surprise weapon precisely because most club players study the famous Fried Liver and are unprepared when White delays the sacrifice with 6.d4.
How the Lolli arises out of the Two Knights Defense
The Lolli is a branch of the Italian Game, reached through the Two Knights Defense: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5. Here Black's principled choice is 5...Na5, which sidesteps the whole mess. The greedy 5...Nxd5?! recaptures the pawn but leaves the knight exposed on d5 and the f7-square chronically weak. That single inaccuracy is the fork in the road. White can play 6.Nxf7, the Fried Liver Attack, or the more flexible 6.d4, the Lolli. Both target f7, and both punish the same mistake. The move order matters, because the Lolli only exists thanks to 5...Nxd5?!. Against the solid 5...Na5 of the Giuoco Piano family, none of the f7 fireworks are available, and White has to play a slower, more positional game instead.
Who was Giambattista Lolli, and why does the attack bear his name?
The opening honors Giambattista Lolli (1698-1769), an Italian master from Nonantola and one of the earliest chess theoreticians of any note. His 1763 treatise Osservazioni teorico-pratiche sopra il giuoco degli scacchi collected and analyzed the sharp Italian Game lines that players of his era favored, including the aggressive tries against the Two Knights Defense that now carry his name. Lolli belonged to the same Modenese school as Ercole del Rio and Domenico Ponziani, who together shaped much of early opening theory. Attaching his name to the 6.d4 line makes sense, since it rewards exactly the kind of forcing, development-driven attack the old Italian masters loved. Lolli's name also attaches to a separate checkmating pattern, Lolli's Mate, which we cover below.
Lolli's Mate
Lolli's Mate is a classic checkmating pattern named after the same player. In its purest form, a queen lands on g7 (or g2 from Black's side) supported by a pawn on f6 (or f3), mating a king trapped on g8 (or g1). In the opening, the queen joins the attack against Black's exposed king after Nxf7 and Qf3+. So the mate pattern and the opening are technically two different things. The opening revolves around the chronic weakness of f7 in front of an uncastled king, which is exactly what 5...Nxd5?! leaves behind.
How to play the Lolli Attack: theoretical lines and the four Black replies to 6.d4
The Lolli Attack starts with a pawn sacrifice, 6.d4, which Black can take with either 6...Nxd4 or 6...exd4. Slow moves such as 6...Be7 let White go all in with 7.Nxf7 Kxf7 8.Qf3+, after which the Black king must either step away from the check with 8...Ke8 or 8...Ke6, or block it with 8...Bf6. All of these give White a clear edge with accurate play. The capture 6...exd4 blows open the e-file, which White tries to exploit by castling at once with 7.0-0 to bring the rook to e1; the immediate check 7.Qe2 is less effective.
6...Be7 (6.d4 Be7 7.Nxf7 Kxf7 8.Qf3+)
Provoking the sacrifice on f7 with a move like 6...Be7 is a poor idea for Black, and it can backfire badly. After 7.Nxf7 Kxf7 8.Qf3+, Black faces an awkward check.
Two of the legal replies, 8...Ke8 and 8...Bf6, return the extra material at once and leave Black in a sorry position. The third, 8...Ke6, puts up some resistance by defending the d5 knight, but the king in the center is a permanent target.
8...Ke8
Retreating the king to e8 lets White grab the knight with 9.Bxd5, threatening Qf7+. White is a pawn up, has a promising attack, and Black has lost the right to castle. Black has nothing for it except threats to parry. The natural 9...Rf8, stopping Qf7+, runs into 10.Bxc6+ bxc6 11.Qh5+ g6 12.Qxh7, winning even more material.
The trickier try is 9...Nxd4, which grabs a pawn and threatens a fork with Nxc2+. White defends c2 first with 10.Qf7+ Kd7 11.Be4.
Now Black usually chases the intrusive queen off f7 with 11...Qf8. White simply retreats the queen, drives the knight back, and keeps attacking. A sample line: 11...Qf8 (also making luft on d8 for the king) 12.Qd5+ Bd6 13.c3 c6 14.Qc4 Ne6 15.0-0, and Black will struggle to coordinate his pieces.
8...Ke6
The most intuitive reaction is to stay and defend the d5 knight with 8...Ke6. White must continue with 9.Nc3, otherwise Black consolidates. Here 9...Nxd4 fails to 10.Bxd5+ Kd6 11.Qd3, and Black is in deep trouble, while 9...Nb4 walks into a crushing attack. One line that shows White's prospects: 10.0-0 Rf8 11.Qe4 c6 12.a3, chasing the knight off the defense of d5, 12...Na6 13.Qxe5+ Kf7 14.Qh5+ Kg8 15.Nxd5 cxd5 16.Bxd5+ Kh8 17.Be4, and Black has to give up a lot of material to deal with the simple mate threat Qxh7#.
8...Bf6
Blocking the check with 8...Bf6 is the weakest of the three options, because it hands the material straight back without any fight. After 8...Bf6 9.Bxd5+ Black is forced into 9...Be6, because 9...Ke7 runs into 10.Bxc6 bxc6 11.dxe5 Bxe5 12.Bg5+ Bf6 13.Bxf6+ gxf6 14.Nc3, and the Black king is too exposed with nothing to shield it.
So after 9...Be6, White clears the center with a few trades, for example 10.Bxe6+ Kxe6 11.dxe5 Bxe5 (11...Nxe5 12.Qxb7) 12.Qh3+ Kf7 13.Qb3+ Kg6 14.0-0, and the Black king is completely exposed.
6...exd4
The capture 6...exd4 is the weaker of the two ways to take, because it opens the e-file. White exploits Black's lag in development by castling quickly and seizing the e-file with the rook.
7.0-0
After White castles it is hard to find a good move for Black, because a routine try like 7...Be7 runs into the thematic 8.Nxf7. Engines suggest the strange idea of slamming the e-file shut with a knight sacrifice, 7...Ne5 8.Re1 Ne3, the point being that 9.fxe3 allows 9...Nxc4. Very few human players will ever find that resource.
A more natural continuation is 7...h6 8.Re1+ Nce7 9.Qh5 g6 10.Qf3, threatening Qxf7+ and hitting d5 at the same time, 10...hxg5 11.Bxd5 Qd6, freeing d8 for the king, 12.Bxf7+ Kd8 13.g3, defending h2. The material count looks level for the moment, but White is positionally winning thanks to the stranded Black king and the discoordination of Black's pieces.
7.Qe2
The reason 7.Qe2 is less effective is that Black can now block the check with 7...Be7, because the thematic sacrifice on f7 arrives a tempo slower than in the line above. For example, 8.Nxf7 Kxf7 9.Qf3+ (White has spent two moves, Qe2 then Qf3+) 9...Ke8 10.Bxd5 Rf8 11.Bxc6+ bxc6 12.Qxc6+ Bd7. Black is down material but has the initiative and coordinated pieces, while White's only active piece is the queen.
6...Nxd4
The soundest reaction for Black is to capture on d4 with the knight, which neither opens the e-file nor allows Qf3+. The Nxf7 idea does not work here. White's only move to keep an edge is 7.c3, kicking the knight. Black cannot retreat it: 7...Ne6 8.Qxd5! Qxd5 9.Bxd5 and the g5 knight is defended, 9...Nxg5 10.Bxg5.
So Black has to resort to the ugly 7...f6, weakening the king, to make ...Ne6 possible. For example 8.0-0 Ne6 (8.cxd4 Bb4+ 9.Bd2 Bxd2+ 10.Nxd2 fxg5 is also good for White) 9.Bxd5 fxg5 10.Qb3, and White keeps the pressure.
6...Bb4+
A rarer way to decline the pawn is the check 6...Bb4+, trying to disturb White before castling. After 7.c3 the bishop must move again, and 7...Be7 simply walks back into the thematic blow: 8.Nxf7 Kxf7 9.Qf3+ Ke6 10.Qe4. Black holds d5 with 10...Bf8, freeing e7 for the knight, but after 11.0-0 White is fully mobilised while Black's pieces shuffle backwards. The familiar pattern, Nxf7, Qf3+, Qe4, shows up yet again, which is exactly what makes the Lolli so easy to play once you know the idea.
Is the sacrifice worth it? The trade-off in plain terms
Pros
- With an accurate play, white has a crushing attack with active pieces.
- Even if black returns the material, oftentimes it is at the cost of a ruined structure, which white can strategically exploit.
Cons
- Requires calculation skills and technique to convert the attack to a full point.
- Black may capitalize on the material advantage in the long run, if they may manage to consolidate their position successfully
The engine's verdict: is the sacrifice really sound?
Strip away the fear factor and ask what Stockfish thinks, and the honest answer is mixed. After 6.d4 and the thematic Nxf7, the engine evaluation favors White in every main line given accurate play. The open king and the lead in development outweigh the sacrificed material. The catch is that several of White's wins require only-moves a human under pressure may not find. The most striking example runs the other way. Against 7.0-0, the engine suggests the strange defensive resource 7...Ne5 8.Re1 Ne3, slamming the e-file shut by hanging a knight, because 9.fxe3 allows 9...Nxc4. Almost no club player will spot that save over the board. Even solid opponents almost never find it against me. That gap between engine truth and human practice is exactly why the Lolli scores so well below master level.
The Lolli Attack in practice: Fischer's simuls and Euwe's technique
You will rarely meet the Lolli in elite play, but it has a sharp practical record everywhere else. Bobby Fischer was happy to wheel it out in simultaneous exhibitions back in 1964, treating 5...Nxd5?! as an invitation rather than a problem to solve. Earlier still, former World Champion Max Euwe showed how to handle the positions where Black returns the material: instead of forcing matters, White settles for a small but lasting edge, two minor pieces working against a passive rook, and converts it on technique.
The thread running through these games is the one that runs through the whole opening: keep developing as if you had never sacrificed. Not every Lolli ends in mate on h7. Often the reward is simply a safer king, a healthier structure, and pieces that all point at the enemy.
Case Study: Punishing 8...Ke6 in the center
The best illustrative line in this article is the 8...Ke6 main line, where Black keeps the extra material and tries to hold the center instead of returning it. It is the most complete picture of what the Lolli is really about, since White wins by development and pressure rather than a single trick. Treat it as a model attacking sequence, not a specific tournament game.
Here is what the moves teach a club player.
- 7.Nxf7 Kxf7 8.Qf3+ is the engine room of the whole opening. The knight comes off, but the check drags the king to a square where it has no shelter. Note that the king cannot run home: f7 is gone, and every queen check finds it.
- 8...Ke6 is Black's most stubborn defense, holding the d5 knight rather than giving the material back. The drawback is obvious once you see it: the king now stands in the middle of the board on move eight.
- 9.Nc3 is the move that turns a tactical flurry into a winning attack. White does not chase a forced mate. He develops, adds a piece to the assault, and hits d5 a second time. If White grabs material instead, Black untangles. The instructive point is that you keep bringing pieces in.
- 9...Nxd4 tries to win a pawn and trade off an attacker, but 10.Bxd5+ Kd6 11.Qd3 leaves the Black king marooned on d6 with White's pieces converging. The position is close to resignable for a human, even though the material is roughly level.
- The 9...Nb4 sideline in the bracket is the turning point worth memorizing. After 10.0-0 Rf8 11.Qe4 c6 12.a3, White first castles into the attack, then kicks the defender of d5. The finish, 13.Qxe5+ Kf7 14.Qh5+ Kg8 15.Nxd5 cxd5 16.Bxd5+ Kh8 17.Be4, sets up an unstoppable Qxh7#, and Black must shed material to survive.
The practical takeaway is the one habit that wins these positions: after Nxf7 and Qf3+, resist the urge to calculate a mate on every move. Castle, play Nc3, bring the rook to e1 or e4, and let the exposed king do the work. The attack plays itself once every piece is pointing at the king.
Should you add the Lolli Attack to your repertoire?
The Lolli Attack is a thrilling alternative to the Fried Liver and a tactically justified way to punish Black's early inaccuracy. Because White sacrifices material, a precise follow-up is needed to finish the job, so any Italian player who wants to use it should study Black's replies in depth, right up to the point where White's advantage is already clear. That preparation builds confidence over the board and adds to the pressure on your opponent, who will already be having a hard time defending a fearless attack.
