Blackburne Shilling Trap

The Blackburne Shilling Trap: Black offers the e5 pawn with 3...Nd4, and 4.Nxe5? runs into 4...Qg5 and a smothered mate. Line, refutation and real fall rates.

Set byBlack
Losing move4.Nxe5? → 4...Qg5!

Black plays the odd-looking 3...Nd4 and leaves e5 hanging. Taking it is the mistake the whole line is built on. The move 3...Nd4 is objectively poor, so the trap only works if White grabs the pawn.

Blackburne Shilling Trap

Getting there…

4.Nxe5 wins a pawn and threatens f7, but 4...Qg5! attacks the knight and the g2 pawn together. If White carries on with 5.Nxf7, then 5...Qxg2 6.Rf1 Qxe4+ 7.Be2 Nf3 is a smothered mate. The least bad option after 4...Qg5 is 5.O-O Qxe5 6.c3, giving up the knight for a pawn and some development.
