Although there is a general belief that this gambit, usually referred to as the Blackmar-Diemer Gambit , is not fully sound it has nevertheless resulted in numerous rapid and spectacular White wins.} dxe4 3. Nc3 Bf5 ({ Some opening authorities recommend here} 3... e5 {intending to return the pawn for a promising Black game but White has instead the curious} 4. Qh5 {-the so called Sneiders Attack- when the complications are only just beginning.}) (3... Nf6 {a very common position often arrived at via 1.d4 d5 2.Nc3 Nf6 3.e4 dxe4 and now} 4. f3 Bf5 {transposes to the main game position after move 4} ({ Generally though Black accepts the gambit with} 4... exf3 5. Nxf3 {a line very frequently played nowadays as White by the strong player Leisebein even against players around and above 2400+ elo .})) 4. f3 Nf6 {Play has now transposed to the so called Vienna Defence recommended by Hans Muller in the 1950s.} 5. g4 {Weakening the kings-side pawn structure but introducing mayhem, or perhaps more politely imbalance, into the position which is one of the main aims of the Blackmar-Diemer Gambit. In recent opening texts this has even been nicknamed the Hara-Kiri Gambit!} (5. fxe4 {is the main alternative when Black most often prefers to recapture with the knight} Nxe4 ({although Gary Lane makes a case for the paradoxical move} 5... Bxe4 $5 6. Nxe4 Nxe4 {less often played but much less tactical.}) {when} 6. Qf3 {instigates enormous complications.}) 5... Bg6 {The consistent reply whereas} (5... Be6 {blocks the e-pawn from moving and White recovers the pawn and also gains the centre after} 6. g5 Nd5 7. fxe4 Nxc3 8. bxc3) 6. g5 {It's probably best to regain the pawn although White's kings-side pawns are a little loose. White may also choose to try and hunt down the Bg6 with} (6. h4) ({or the less commonly played} 6. f4) 6... Nd5 7. Nxe4 (7. fxe4 {offers another gambit after which} Nxc3 8. bxc3 Bxe4 9. Nf3 {gives White some potential play on the open e- and f- files but is somewhat dubious.}) 7... e6 {Although by far the most frequent move chosen by Black in this position modern opening theory prefers the development move} ( 7... Nc6 {with a very comfortable game.}) 8. Ne2 {This does not appear White's best line. Opening texts detail instead} (8. c4) ({and} 8. h4) 8... Nd7 { Solid but the more active} (8... Nc6 {secures Black a good game as in Richter-Perez Garcia LSS e-mail 2013.}) 9. c4 {Now White is Ok but is less so after the few other games that have seen} (9. Nf4 Nxf4 ({or also} 9... Bb4+)) ( {as well as after} 9. a3 c5) 9... Bb4+ {This should have been fine for Black but perhaps a false sense of security arose after White's next forced, but very accurately calculated, move.} (9... N5b6 {as played in Elieff-Findley, London Fall op Canada 1995 also secures Black an even game.}) 10. Kf2 (10. Bd2 {is poor after} Ne3 11. Qc1 Bxd2+ 12. Qxd2 (12. Kxd2 Nxf1+ 13. Rxf1 h6 { and White is in difficulties}) 12... Nxc4 {wins a clear pawn.}) ({whilst} 10. Nd2 {loses the White queen to} Ne3) 10... Ne7 {Now Black begins to go downhill in blocking an escape route for the Bb4 although it looks like he has set what, at first sight, seems a very clever trap. Instead, correct was} (10... N5b6 11. h4 ({The attempt to trap the bishop with} 11. c5 {fails to} Nxc5 {and if} 12. a3 Nxe4+ 13. fxe4 {and Black again has Be7.}) 11... Bxe4 12. fxe4 Be7 {and the bishop is out of trouble and Black has a solid even game.}) 11. a3 Bxe4 12. fxe4 Bd6 ({Instead} 12... Ba5 {offers no hope following} 13. b4 Bb6 14. c5) 13. c5 Nxc5 {Possibly Black even thought this was winning but White has a move that trumps it.} 14. dxc5 Bg3+ {This seems to win the White queen for just two bishops.} (14... Bxc5+ {also doesn't work as Black only gets two pawns for the piece. In addition, the White king is perfectly safe in the centre as Black has no real attacking chances after} 15. Be3 Bxe3+ 16. Kxe3) 15. Nxg3 {The winning recapture. Of course if the pawn or king recaptures then Black's idea works perfectly and wins.} Qxd1 16. Bb5+ (16. Bb5+ {wins the Black queen and ends up a piece up for a pawn via} Qd7 ({or} 16... c6 17. Rxd1 cxb5) 17. Bxd7+ Kxd7 {This game, seen in late 1966, is the first game I ever played through. It was (and still is) in a excercise book of press cuttings made up when I first started playing chess and was from one of B.H.Wood's columns (possibly the Illustrated London News). It exerted something of a slight fascination and shows that even after what seemed like some clever chess a game can turn around in a jiffy when this is met by even smarted chess. Many such turnarounds have been observed, especially in otb club chess as well as rapid on-line chess, since that time.}) 1-0
