Another Blackmar-Deimer

1 d4 d5 2 e4 de 3 Nc3 Nf6 4 f3 ef 5 Nxf3 Bg4 6 Be2 White can try 6 Bc4, hoping that black will not see the threat of 7 Ne5. However, in my experience black almost always plays correctly with 6...e6; hence I play 6 Be2 and continue thematically rather than rely on a cheapo. The database move is 6 h3, but it scores a poor 38% for whit. 6...e6 7 0-0 Castling queen-side is probably stronger objectively, but I am more familiar with king-side castling. 7...a6 8 Bg5 Be7 9 Qd2 0-0 10 Rad1 Nd5 11 BxB NxB 12 Ne5 BxB 13 QxB Nd5 14 NxN QxN 15 c3 Nc6 16 Ng4?! The engine likes 16 NxN, and says 16...Qxa2 leaves black a clear pawn up. I was trying to create some king-side pressure. 16...Ne7 17 Ne5 Rad8 18 Rf3 Qd6 19 Rdf1 Nf5 20 g4 Nf6 21 g5 Nf5 22 Rh3 c5? Here black goes wrong. I now get a huge 5-point advantage. 23 Qh5 h6 24 gh Nxh6 25 Rg3? (Rf6!!+-) Kh7 26 Rxf7! RxR 27 NxR Qd5 (mate is now forced) 28 Qg6+ Kg8 29 Qxg7# 1-0
