Sprung by Black. The move that invites it is Re1.

A Petrov classic. 10. Re1 walks into the h2 bishop sacrifice; the f2 knight fork then wins the queen for two minor pieces.

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.
