1. e4 e5 2. Bc4 Nc6 3. Qh5 Nf6
Sprung by White. The move that invites it is Nf6.
The four-move mate. 3...Nf6 develops a piece and loses the game; 3...g6 or 3...Qe7 defends f7 and leaves White's queen misplaced.
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.
