Chess Holy Grail:
The Keoni-Hiva Gambit - Part 1
by Clyde Nakamura

Oh brave chess knight, thou seekest the Holy Grail of Chess...
Behold the Keoni-Hiva Gambit, for it is the ultimate chess opening gambit.

According to Christian mythology, the Holy Grail was the dish, plate, or cup used by Jesus at the Last Supper and is said to possess miraculous powers.  The quest for the “Holy Grail” is a key part of the legend of King Arthur and the Knights of the Round Table.  In the twelfth century AD, the Benedictine monk Geoffrey of Monmouth wrote the book “The History of Kings of Britain”. There are some who have said that his work was pure fiction but according to others, his writings were based on writings by other earlier writers about Arthur and on Celtic myth and folklore.

In medieval Europe the legend of Arthur was already popular prior to the writings of Geoffrey of Monmouth.  The book “Le Morte d'Arthur” popularized the legend of King Arthur.  It was written in 1485 by Sir Thomas Mallory and is a compilation of English and French writings on King Arthur and the Knights of the Round Table.  Other researchers have speculated that Arthur was a war chieftain in the 5^th century AD at the end of the Roman occupation of Britain.

The story of the Keoni-Hiva Gambit started with the Franco-Polish Gambit (1.e4 e6 2.d4 b5). I had wanted to create a reversed form of the Franco-Polish Gambit from the white side but after the moves 1.e3 e5 2.b4 Bxb4 3.f4, I was surprised that black had 3…Qh4+ 4.g3. I had realized that I had arrived at the same position as in the Franco-Polish Gambit a move too early. Thus was born the idea for the Keoni-Hiva Gambit. I decided to use the same ideas as in the Franco-Polish Gambit, but I had to leave out the b4 move. The initial moves for the Keoni-Hiva Gambit that I first experimented with were: 1.e3 e5 2.Nc3 Nf6 3.f4 exf4 4.Nf3. It was only after playing many games with this  gambit that I realized that there were 2 other starting variations. The Hawaiian names for the 3 main lines of the Keoni-Hiva were provided by Eric Schiller.

Keoni is the Hawaiian nickname of my chess student and Hiva is the mythical place where ancient Polynesians came from. Yes, I do consider the Keoni-Hiva Gambit my most deadliest gambit. It is still a work in progress. There are still much  improvements to be made in the various lines.

The kingside attack in the Keoni-Hiva Gambit is very strong. Essentially white sacs 3 pawns for a kingside attack. Being 2 pawns down, white has to play for the win. There is no turning back. If your attack fails then you will lose the endgame. Computer opponents tend to take all 3 of the pawns. Against human opponents you could see more variation in the number of pawns being taken from 1 to 3 pawns taken or even declining the gambit altogether.

The moves for the Keoni-Hiva Gambit is as follows:

Line 1 (Akahi Variation): 1.e3 e5 2.Nc3 Nf6 3.f4 exf4 4.Nf3
