In this article we will cover the three main accepted lines of the Omega-Osiris Gambit. They are: 1.d4 d5 2.Nf3 e5 3.dxe5 f6 Transpose into a Soller Gambit (1.d4 e5 2.f6) The Soller Gambit is a reversed form of the Blackmar-Diemer Gambit (1.d4 d5 2.e4 dxe4 3.Nc3). Like the Blackmar-Diemer Gambit, the Soller Gambit’s main aim is a direct Kingside attack. Black can use the half open f file to conduct a Kingside attack, but Black must be prepared to sacrifice material to blow open White’s Kingside position. 1.d4 d5 2.Nf3 e5 3.Nxe5 Nc6 4.Nxc6 dxc6 Reversed Omega Gambit (1.d4 Nf6 2.e4) A key theme in this particular line of the reversed form of the Omega Gambits is that the side accepting the gambit gets into trouble in the middlegame because of the exchange of Kings Knight for Black’s Queen’s Knight. This leaves the White kingside vulnerable to a Kingside attack because there is one less defender on the Kingside. 1.d4 d5 2.Nf3 e5 3.Nxe5 Nc6 4.Nf3 Reversed Omega Gambit Line
White drops 2 tempo (moves) by retreating his Knight to f3. With the half
open f file and a slight development advantage, I believe Black has
compensation for the gambit e pawn. GAMBIT ACCEPTED

1.d4 d5 2.Nf3 e5 3.dxe5 f6 This is a transposition to the Soller Gambit (1.d4 e5 2.dxe5 f6) which is a reversed form of the Blackmar-Diemer Gambit (1.d4 d5 2.e4 dxe4 3.Nc3). Like the Blackmar-Diemer Gambit, the Soller Gambit’s main aim is a Kingside attack. Black will gather all his pieces and attempt to break through White’s kingside with piece sacrifices. |
|
If White fianchettos his King’s Bishop then
Black will exchange Bishops to weaken the White castled position. If
White castles Queenside then Black’s strategy is to sink the “a” pawn down
to a3 creating weaknesses in the White Queenside castled position. I will
not cover the Soller Gambit in depth in this article because I will probably
write a separate article on the Soller Gambit. An interesting article
called “Come to the Dark Side” by Tim McGrew of the “Gambit Cartel” at
www.chesscafe.com covers the Soller Gambit. This is article number 33
which is in the archives section of Chess Café. You would have to

The reason why this Omega Gambit in the main accepted line is dangerous after White exchanges his King’s Knight for Black’s Knight at c6 is because, Black gets: 1. A temporary mobility advantage because of the half open f-file and free movement of pieces. 2. An advantage in attacking versus defending pieces on the kingside because the other side has spent three moves exchanging his king-knight for your queen-knight. This leaves your opponent one less piece to defend his kingside with (if your opponent castes kingside.} |
In the following two games White attacks the Queenside and tries to pick off pawns on the Queenside. This is really is a bad strategy for White because it is easy for Black to neutralize the White attack with simple defensive moves. In the meantime, Black’s attack on the kingside becomes a major problem for White.

|
|
In this line of the Omega-Osiris Gambit, White retreats his Knight to f3 but loses two tempo (moves). The general rule of thumb in chess is that three tempo are equivalent to one pawn. I believe that Black gets enough compensation with two tempo plus open lines and active pieces. However both Deep Fritz 8 and Deep Junior 10 give White a slight plus of +/= 0.66, but this is based mostly on a material evaluation. |
