WHITE TRAPTrap 1: The Legal Trap (Legal's Mate)
How to avoid it: as Black, after 5.h3 take the knight with 5...Bxf3 or go back with 5...Be6. If you already played 5...Bh5 and White takes on e5, play 6...Nxe5: you lose a pawn, not the game.
The Italian Game, 1.e4 e5 2.Nf3 Nc6 3.Bc4, is the first opening many players learn, and it is full of traps. Two traps in this article are for White: a queen sacrifice that ends in mate, and the famous Fried Liver Attack. Two are for Black: the Blackburne Shilling trap and the Traxler Counterattack. Each trap is on its own board with the side lines, a Stockfish evaluation and a short "how to avoid it".

Trap 2 below is the Fried Liver Attack. In this video from our Stockfish channel, Stockfish 18 plays it against LeelaZero. Watch it, then replay each trap on the boards at your own speed.
| # | Trap | For | The mistake | Stockfish after it | What it wins |
|---|---|---|---|---|---|
| 1 | The Legal Trap | White | 6...Bxd1?? | Mate in 2 | The game (mate) |
| 2 | The Fried Liver Attack | White | 5...Nxd5? | +0.9 for White | A strong attack (7...Kg8?? = mate) |
| 3 | The Blackburne Shilling Trap | Black | 5.Nxf7?? | -5.1 for Black | The game (smothered mate) |
| 4 | The Traxler Counterattack | Black | 7.Ke1?? | -7.0 for Black | The h1 rook |
How to use the boards: press ▶ Play or tap a move. The buttons above each board switch to the side lines (what if the other player plays something else). Arrows show the threats; draw your own with a right-click drag. The numbers are Stockfish 18 evaluations: + means White is better, - means Black is better.
Both White traps punish a natural move: keeping a pin with ...Bh5, and taking back on d5 with the knight. They are the best known Italian Game traps for White.
How to avoid it: as Black, after 5.h3 take the knight with 5...Bxf3 or go back with 5...Be6. If you already played 5...Bh5 and White takes on e5, play 6...Nxe5: you lose a pawn, not the game.
How to avoid it: as Black, after 4.Ng5 d5 5.exd5 do not take back. Play 5...Na5! and hit the bishop. If you are already in the Fried Liver, the king must go to e6, never g8.
Both Black traps are gambits. They are not the best moves on the board (Stockfish prefers White after 3...Nd4 and after 4...Bc5), but one natural reply by White loses at once.
How to avoid it: as White, meet 3...Nd4 with 4.Nxd4 exd4 5.c3 or simply castle with 4.O-O. Never take on e5 with the knight while the black knight sits on d4.
How to avoid it: as White, answer 4...Bc5 with 5.Bxf7+, or after 5.Nxf7 Bxf2+ play 6.Kf1!. If you took on f2, the king goes to g1 after 6...Nxe4+, never back to e1.
The Legal Trap is named after the French player Sire de Legall. In his famous game against Saint Brie in Paris he gave rook odds and won with this mate. Most books date the game 1750, but some historians think 1787 is more likely. The modern version with 5.h3 Bh5 comes from later games.
The Blackburne Shilling Gambit is named after the English master Joseph Henry Blackburne. The story is that he set this trap in cafes and won a shilling a game. There are no recorded games of Blackburne playing it, so the story may not be true. It is also called the Kostic Gambit.
The Traxler Counterattack is named after Karel Traxler, a Czech problem composer, who played it against Reinisch in Prague in 1890. Frank Marshall later called it the Wilkes-Barre Variation, after the town in Pennsylvania.
Most Italian Game traps work against one weak square: f7 for Black and f2 for White. Only the king guards it at the start. Three simple habits keep you safe:
For the plans and main lines (Giuoco Piano, Evans Gambit, Two Knights), read our Italian Game guide, the full Fried Liver Attack guide and the Evans Gambit.
The Fried Liver Attack: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5? 6.Nxf7! Kxf7 7.Qf3+ and the black king must walk to e6. The Legal Trap, which ends in mate on move 8, is just as well known.
Yes, two in this article. In the Legal Trap, after 5.h3 Bh5? 6.Nxe5! Bxd1?? 7.Bxf7+ Ke7 8.Nd5# White mates. In the Fried Liver, 5...Nxd5? lets White sacrifice on f7 and attack the king.
The Blackburne Shilling trap (3...Nd4 4.Nxe5? Qg5! 5.Nxf7?? Qxg2 6.Rf1 Qxe4+ 7.Be2 Nf3#) and the Traxler Counterattack (4.Ng5 Bc5!?). Both are gambits that Stockfish does not trust, so use them as surprise weapons.
Not by force. After 7...Ke6 8.Nc3 Nb4 Black can defend, and Stockfish gives White only about +0.7. But Black must find exact moves; 7...Kg8?? loses to mate in 3. The safe way for Black is 5...Na5.
Do not take on e5. Play 4.Nxd4 exd4 5.c3 or 4.O-O, and White is better (Stockfish +0.7 to +1.0). Even after 4.Nxe5 Qg5, the move 5.Bxf7+ keeps White in the game.
They are the same idea. The trap is the queen sacrifice 6.Nxe5!, and the mate at the end (Bxf7+ and Nd5#) is called Legal's Mate.
