1. e4 e5 2. Nf3 Nf6 3. Nxe5 Nxe4 4. Qe2 Nf6
Sprung by White. The move that invites it is Nf6.
Copying White in the Petrov fails: after 4. Qe2 the knight must not retreat into the discovered check 5. Nc6+, which wins the queen. Black needs 3...d6 first.
Read as: how often this trap line is completed per sampled game in the band.
How the Blunder Rate is measured. A material swing of three points or more inside the first 24 half-moves after leaving book, detected without an engine evaluation. It is a proxy for how sharp a position is in practice, not an engine verdict, and it is computed from a monthly game sample rather than the full corpus behind the win rates. Trap hit rates count a trap only when its full line is completed on the board.
