In the following game I had a great idea for what I thought was a winning, "passive" sacrifice. Black could decline the piece and stay in trouble, or take it and get into worse. Or so I thought...

blitz, FICS, 2010
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4
The Blackburne Shilling Gambit.
I have scored 93% against this counter-gambit, according to the updated New Year's Database; yet still they come...
4.Bxf7+ Kxf7 5.Nxe5+ Ke6
6.c3 Kxe5 7.cxd4+ Kxd4
Taking the pawn is risky for Black, yet out of 77 games in the updated New Year's Database, when he did so, White scored only 49%.
8.d3 Bb4+ 9.Nc3
I had recently looked at this and the possible pawn sacrifice at c3 and was sure that White would checkmate the enemy King in response.
After the game Rybka indicated a preference for 9.Ke2 Ke5 10.Qb3 winning the Bishop on b4.
9...Bxc3+ 10.bxc3+ Ke5
Or 10...Kxc3 11.Qb3+ Kd4 12.Qd5+ Kc3 13.Qc4#
11.Qh5+ Ke6 12.Qf5+ Ke7 13.Bg5+ Nf6 14.e5
Black's King has returned home, but his adventure will cost a piece. He should now play 14...Kf7 and after 15.exf6 gxf6 16.Be3 try to hang on.
14...Rf8 15.exf6+ gxf6 16.0-0
Aggressive play, offering the Bishop, but Black has a defense that I had overlooked!
16...Rf7
I had checked only as far as 16...fxg5 17.Rfe1+ Kd6 18.Qe5+ Kc6 and figured that with the open b-file available to let White's other Rook join the fight, the sac was winning. I guess my opponent didn't look further, either, as he declined the piece.
Yet, after 19.c4 a6 20.Rab1 d6 Black's King is safe,

and White has nothing better than repeating the position with 21.Qe4+ Kd7 22.Qe6+ Kc6 25.Qd5+ etc.
Black's chosen move, however, allows White to add fuel to the fire.
17.Rfe1+ Kf8 18.Bh6+ Kg8 19.Re3
19...d6 20.Rg3+ Kh8 21.Qd5
The Queen would have been even more powerful at h5.
21...Qe7 22.Re3
One more thing for my opponent to worry about, as I'm targeting the back rank as well as his Queen. Now Black's game collapses.
22...Qd7 23.Rae1 Qe6 24.Rxe6 Bxe6 25.Qxe6 Raf8 26.Bxf8 Rxf8 27.Qe7 Rg8 28.Qxf6+ Black resigned
