The Omega Gambit (1.d4 Nf6 2.e4) Part 1 by Clyde Nakamura Introduction After I had independently discovered the Gibbins-Weidenhagen Gambit (1.d4 Nf6 2.g4) I realized that there was another possible gambit after 1.d4 Nf6. I believed that 2.e4 was possible. I named this new gambit the Omega Gambit after watching a Charlton Heston movie called "The Omega Man". Omega (Ω) is also the last letter in the Greek alphabet.
The starting position of the Omega Gambit. The Omega gambit can also be played by the move sequence 1.e4 Nf6 which is an Alekhine’s Defense (1.e4 Nf6) and 2.d4. National Master Robert Reynolds, Grandmaster Hellers, Grandmaster Nick DeFirmian, Master Tim McGrew of the Gambit Cartel on www.chesscafe.com and according to Eric Schiller a number of Chicago players had also played this gambit. The Omega Gambit has also been called the Reynolds Gambit and the Bo Gambit. The main Omega Gambit accepted line is 1.d4 Nf6 2.e4 Nxe4 3.Nc3 Nxc3 4.bxc3. The variation 1.d4 Nf6 2.e4 Nxe4 3.Bd3 is called the Arafat Gambit. Another possible accepted line is 1.d4 Nf6 2.e4 Nxe4 3.Nd2 which was suggested by my computer chess program Zarkov. Also possible is 1.d4 Nf6 2.e4 Nxe4 3.Nc3 Nf6 where Black does not exchange his Knight. This is the other main accepted line. If Black does not play the 2…Nxc3 move right away White can still play the gambit by playing 3.Be3. The following game was my first tournament game with the Omega Gambit, from the year 1985. This game appeared in a Rand Springer article in German with the title of “Freak Offense”. I went on to play some test games against some of my computer chess programs and in many 5-minute blitz games on the Internet Chess Club, The USCL Chess Server and on Playchess.com.

Black has exchanged his King Knight for White’s Queen Knight. The tempo count remains the same but Black has weakened his king side. He has one less piece guarding the king. White has the two Bishops, a half open b-file and a half open e-file to work with. White’s king side attack if very dangerous and Black has to play a very precise defense to survive.

Kb1 1-0 Conclusion If Black accepts the gambit pawn with 2…Nxe4 then White gets compensation in quick development, the advantage of the 2 Bishops, the half open e file. In the main accepted line 1.d4 Nf6 2. e4 Nxe4 3.Nc3 Nxc3 4.bxc3 White gets a very dangerous king side attack because there is one less piece defending the king side. If Black does not exchange the knights by playing 3…Nxc3 but plays 3…Nf6 instead, White can continue the attack with 4.g4. This line also gives White a good game. If Black fianchettos on the king side then White often plays the move h4 before castling and tries to line up the Queen and Bishop on the diagonal preparing to trade off his Bishop with Black’s Bishop at g7. And White pushes the h pawn to open up the h-file to penetrate Black’s king position with the Queen and Rook lined up on the h file. If Black plays an early h5, stopping White’s h pawn advance, then White targets the g6 pawn to execute a cascade of sacrifices on g6. The move h5 weakens Black’s fianchetto position. White also often doubles his rooks on the e file to facilitate the series of piece sacrifices on the g6 square. Or white could post a knight at e5 to further target the g6 pawn.
I have had many interesting games with the
Omega Gambit. In the gambit accepted lines it
is not unusual for half of Black’s pieces to
be still on the back rank while White’s attack rages on. In a lot of
the gambit accepted games I have played, White gets very quick mobility and
full development (White has castled, his minor pieces are all developed, his
2 rooks are connected and the queen is off the back rank.) early in the
game. Black has to play extremely precise defense to survive. Here is a file with 14 games free for you to download. It will be a pgn file called omega1.pgn. Best Regards, Clyde Nakamura
