Blackmar-Diemer Flawed Ryder

Rick Torning played this flawed Blackmar-Diemer Gambit Ryder. He wrote:
"Greetings Tim, Attached is a slightly 'flawed' Ryder Gambit declined opening. I followed the known paths for 7 moves then my opponent varied with 0-0. I had the choice of castling 0-0-0 or 0-0. My natural instinct was to go for the jugular with an attack on h7! That is why I opted for my queen to get to h4. My 13th, 14th, and 15th moves may have surprised my opponent!? Black is losing after 13...Qxf6?? (What else was there apart from h6). I hope you enjoy the finish - it is typical BDG fun! Regards, Rick Torning

Torning,Rick - NN, Casual Bullet lichess game, 07.04.2018 begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Qxf3 D00 Blackmar-Diemer Gambit: Ryder Gambit Declined 5...e6 6.Be3 Be7 7.Bd3 (all in Tim Sawyer's BDG Book 3 Chapter 1.2) 7...0-0 8.Qh3?! Is this a new move in this variation - it is not in any of my databases and maybe for a good reason? However, I wanted the queen on h4. 8...Nc6 9.Nf3 Bb4= [9...e5!] 10.0-0 [10.Ne5!] 10...e5 11.Qh4 exd4 12.Nxd4 [Setting up for a rook sac on f6.]
12...Re8? [Black's Nc6 and queen attack the White Nd4. Black is also attacking the undefended Be3 and gains control of the e-file with the rook. At first blush, it is hard to believe such an active move is poor. Better was 12...Ne5!? 13.Bg5 Nxd3 14.Bxf6 gxf6 15.Rad1 Qxd4+ 16.Qxd4 Bc5 17.Rxd3 Bxd4+ 18.Rxd4 Kg7 19.Ne4 f5 20.Ng3 Kg6 21.Rdf4 Be6 22.Nxf5 Bxf5 23.Rxf5=] 13.Rxf6!? Qxf6?? A fatal attraction! No queen or horse trading today! 14.Qxh7+! Kf8 15.Nd5!! White wins on time. A pretty move as White's Nd5 controls the flight square e7 and attacks Q, B and pawn c7 for a potential rook fork. Black could have tried 15...Ne7 but after 16.Qh8+ [also winning is the longer forcing sequence 16.Nxf6 Ng6 (16...gxf6? 17.Bh6#) 17.Qg8+ Ke7 18.Qxe8+ Kxf6 19.Rf1+ Nf4 20.Rxf4+ Bf5 21.Rxf5+ Kg6 22.Qxf7+ Kh7 23.Rh5#] 16...Ng8 17.Bh7 with mate to follow on g8. 17...g6 18.Qxg8# 1-0 [Game notes by Torning]
