There exists a chess opening Universe that I am just beginning to understand. What if you could play a Black chess opening from the White side of the board? 1.e3 e5 2.e4 is an example of an Inverse Chess Opening. This would be like playing Black from the White side with the same move count. You can have the same openings from the White side as you do from the Black side. Another example, after 1.e3 e5 2.e4 which is a double King Pawn opening, Black can play 2…Nf6 3.f4 and you have an Inverse Latvian Gambit (1.e4 e5 2.Nf3 f5) from the white side of the board. However the orientation of the pieces is different. I am not sure if orientation makes a difference in a game. In an Inverse Chess Opening you give up a move as White to play a Black Opening with White. A reverse chess opening is an opening that you play with reversed colors but there is no move loss. An Inverse Chess Opening is a chess opening where you play an opening of the opposite color with the loss of one move. The term “Inverse Chess Opening” was invented by Eric Schiller. My friend National Chess Master Reynolds Takata asked why play an Inverse Chess Opening. I said that it would double the amount of chess opening gambits I can play from the White side of the board and create chaos and confusion on my opponents part. My point is why not play an Inverse Chess Opening if you are familiar with the opening from the Black side?
Inverse
Elephant Gambit In 2004 I had played an Inverse Elephant Gambit (1.e3 e5 2.e4 Nf6 3.d4) game on the chess server Playchess.com and had called this new opening the Shiva-Elephant Gambit. Shiva is the third god of the Hindu Triad and is the destroyer of the world and of all evil. Other members of my Yahoo-based Unorthodox Chess Opening Newsgroups have said that this opening is an Elephant Gambit (1.e4 e5 2.Nf3 d5) and should be called an Elephant Gambit. I disagreed because the opening move sequence is different and you really have a different chess board orientation. However, the theory, strategy and tactics is really the same as the Elephant Gambit. If you are well versed in the Elephant Gambit, you should not have any problems playing the Shiva-Elephant Gambit.

It seems Black did not play the pawn moves right because White ended up picking off some of those pawns. White started with a very small advantage but this advantage grew larger and larger as the game progressed till the endgame was lost for Black. The extra piece was the deciding factor in this game.
