Regicide

Although the Blackburne Shilling Jerome Gambit leads to play that is "objectively" even, Black's King often suffers the consequences of a defender's mis-step.

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5 7.cxd4+ Ke6 

Black wisely decides not to feast upon any pawns. He has had a couple uncomfortable past experiences: 7...Kxe4 8.Qg4+ Kd5 9.Nc3+ Kc6 10.d5+ Kd6 (10...Kb6 11.0-0 Nf6 12.Qd4+ Bc5 13.Na4+ Ka6 14.Nxc5+ Kb5 15.a4+ Ka5 16.d3 b5 17.b4+ Kb6 18.a5 checkmate, Dropshot - chaparov, standard, FICS, 2011)11.d4 Ke7 12.Bg5+ Nf6 13.0-0-0 Kf7 14.Qf4 h6 15.Bxf6 Qxf6 16.Qxc7 Bd6 17.Qc4 b5 18.Nxb5 Ba6 19.Nxd6+ Qxd6 20.Qb3 Rhc8+ 21.Kb1 Bc4 22.Qf3+ Kg8 23.Rhe1 Bxd5 24.Qh5 Bf7 25.Qa5 Qxh2 26.g4 Qxf2 27.g5 Qc2+ 28.Ka1 h5 29.Rf1 Bg6 30.Qd5+ Kh7 31.Qxd7 Rf8 32.Rh1 Rf2 33.Qb7 Re8 34.d5 Ree2 35.Rb1 Qa4 36.Qc6 Bxb1 37.Rxh5+ Kg8 38.Qxa4 Bxa2 39.Qe8+ Rf8 40.Kxa2 Rexe8 41.d6 Rd8 42.g6 Rf5 43.Rxf5 Rxd6 44.Rf7 Rxg6 45.Rxa7 Kh7 46.Ra3 Kh6 47.Rh3+ Kg5 48.b4 Kf5 49.Rf3+ Ke4 50.Rf8 Rb6 51.Kb3 g5 52.Ka4 g4 53.Ka5 Rb7 54.Rg8 g3 55.b5 Kf4 56.Ka6 Rf7 57.b6 Kf3 58.b7 g2 59.b8Q Rf6+ 60.Ka7 Rf7+ 61.Ka8 Kf2 62.Qh2 Kf1 63.Rxg2 Ke1 64.Kb8 Rf8+ 65.Kc7 Rf7+ 66.Kd8 Rf8+ 67.Ke7 Rf1 68.Qe5+ Kd1 69.Qa1 checkmate, Truntin - chaparov, blitz, FICS, 2012.

8.Nc3 Bb4

A casual move that brings much misfortune.

9.Qb3+ 

The obvious move for White, but is there more for him than just a piece? He decides to find out.

9...Kf6 10.Nd5+ Kg6 11.Nf4+ Kg5

Where the King wanders matters: 11...Kf6 was necessary to keep Black's losses to only the Bishop on b4. Now the King himself is lost.
