CONCLUSION

Accepted Lines

White has the option of playing either 4.bxc3 or 4. dxc3 after having played 1.c4 Nf6 2.e4 Nxe4 3.Nc3 Nxc3.  The line 4.bxc3 leads to positions similar to the Omega Gambit (1.d4 Nf6 2.e4) 2…Nxe4 3.Nc3 Nxc3 4. bxc3.  The other line 4.dxc3 leads to a position very closely resembling a Boden-Kieseritzky Gambit (1.e4 e5 2.Nf3 Nf6 3.Bc4 Nxe4 4.Nc3). The differences were discussed earlier in this article.

Black can also decline to take the N at c3 and pull the N back to f6.  After 2…Nxe4 White can also play 3.Qc2 or 3.Qf3.  The move 3.Qf3 was tested in the match between the chess engines ristarch and Firefly.  Aristarch played an incredible positional Rook sacrifice which won the game brilliantly in game one.  The move 3.Qf3 is a move which deserves to be explored further with more games and analysis.

The goal in the accepted lines is to play a fluid attacking game.  By fluid I mean that you have a game where all of your White pieces are coordinated for an attack on the black kingside castled position or an attack on another part of the chess board.  You would have your knight posted at the best possible position on the board, your bishops are aimed at the black kingside castled or uncastled position, your pawns do not block the path of your developed pieces, and your Q is in the right position for an attack.
 

Declined Lines

The declined lines 2…d6, 2…e6, and 2…g6 all transpose back into main orthodox lines in the chess openings.  However both the lines 2…e6 and 2…g6 allow White to play 3.e5, chasing the black knight away from the f6 square.  This leads to similar types of positions as in the Alekhines Defense (1.e4 Nf6 2.e5) where White’s pawns chase the black N at f6 and where Black is trying to lure White into overextending its pawn structure so that it can become weakened and be subjected to an attack.

The line 2…e5 3.f4 is interesting because Black can take the e-pawn and transpose the game back into a gambit line.  However in the line 3…e5,  White need risk hanging the e-pawn by playing 4.Nc3 first to guard the e-pawn instead of playing the more risky move 4.f4 first.  White can then play the move f4 later without the risk of dropping a pawn at e4.
 

Final Conclusion

I believe that the Omega-Achilles Gambit has at least an even or better than an even chance of winning in both the Accepted and Declined Lines.  It still really comes down to who is the stronger player and to the one who does not make the last major mistake in the game.

To play the Omega-Achillies Gambit well:

1. You should study & analyze the games in this article carefully.

2. Play offhand or blitz games with the Omega-Achilles Gambit.

3. I do recommend that you look at my other Omega Gambit Articles on Chessville because this will give you an idea of how to play an Omega type of gambit.
