I recently ran across an unusual line in the Blackburne Shilling Jerome Gambit that led to some interesting play - no doubt "enhanced" by the blitz time limit. White's creativity is to be applauded.

Blackburne Shilling Gambit.
Blackburne Shilling Jerome Gambit.
4...Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5
A rare, but interesting idea. Most recommended is 7.cxd4+ leading to an equal game.
Not 7...Kxf4 which gave White an immediate payoff after 8.Rf1+ (8.Qh5!?) Ke5 9.cxd4+ Kxd4?! 10.Qa4+ (10.Rf5!?) Ke5 11.d4+ Ke6 12.Qb3+ (12.d5!?) Kd6?! 13.Qd5+ Ke7 Black resigned, drakorg - borodin, FICS, 2002.
Best, as always in this line of the Blackburne Shilling Jerome Gambit, was to retreat the King, e.g. 7...Ke6.
White should not seek to immediately recover his sacrificed material, i.e. 8.cxd4 Kxd4 (8...Kxf4 leads to mate 9.Rf1+ Kg5 10.d3+ Kg6 11.Qg4+ Black resigned, jorgemlfranco - FoldZero, FICS, 2012; 8...d5!?) 9.O-O Bc5 10.Kh1 Qh4 11.Qa4+ Kd5 12.Nc3+ Kd6 13.d4 Bb6 14.Bd2 Nf6 15.Qb4+ Ke6 16.Rae1+ Kf7 17.Qc4+ Kg6 18.f5+ Kh5 19.Ne2 d5 20.Qd3 Ne4 21.Nf4+ Kg4 22.Qf3+ Kxf5 23.Ng6+ Kxg6 24.Qf7 checkmate, richiehill - steadylooking, FICS, 2011.
Best is to lock the enemy King in the center with 8.Qh5.
The King is free. White might as well play 9.cxd4 and accept that he is worse.
But, remember, this is a blitz game!
9...Kc6 10.cxd4 Qe7+ 11.Kf2 Nf6 12.Qf3+ Nd5
In the BSJG, as well as in the Jerome Gambit, Black should always be concerned about blocking in his light-squared Bishop, which in turn blocks his Rook. Best, therefore, was 12...d5!?.
13.Nc3 Qd6 14.Be3 b6 15.Rac1 Kb7 16.Nxd5 c6 17.Nc3
Black has castled-by-hand on the Queenside.
White's advantage isn't his extra, doubled pawn, it is his great lead in development.
17...g5 18.Rhf1 Be7
Black would have done better to stick with his original idea 18...gxf4 19.Qxf4 Qxf4+ 20.Bxf4 d5 and White has only an edge.
More direct was opening the position with 19.d5!?
How ironic: Black erred earlier by putting his Knight on this square, now he is mistaken putting his Queen there. Then as now, ...d5!? was the move with near equality. The locked up pieces will never become part of the game.
20.Qxd5 cxd5 21.fxg5 Rf8+ 22.Kg1 Rxf1+ 23.Kxf1 Bd8
24.Nd6+ Ka6 25.Nxc8 Rxc8 26.Rxc8 Black resigned
