In the Van't Kruijs Opening: Keoni-Hiva Gambit, Akahi Variation, White begins the game with the move e3. This move is a flexible one, allowing the White pawn to control the d4-square while also giving the White bishop a clear path to develop to d3 or b5. Additionally, the pawn on e3 provides an extra layer of protection for the d4-square, making it more difficult for Black to challenge White's central control. In sum, e3 is a solid and efficient opening move that has been used by many Grandmasters throughout history.

When Black plays e5 in response to White’s e3, they are taking control of the central square. This move puts pressure on White's pawn on e3, potentially making it difficult for the White bishop to develop. Additionally, e5 frees up the Black knight on g8 to move to f6, where it can put pressure on White's pawn on e4. Playing e5 is a common response in many openings, as it allows Black to take an active stance and fight for control of the board.

By playing Nc3 in response to Black’s e5, White aims to put pressure on the Black pawn. The knight on c3 is also well positioned to support the d4 square, further strengthening White's control over the center of the board. Additionally, Nc3 prepares for the development of the White bishop to b5, which would put pressure on Black's pawn on f7. Playing Nc3 is a common move in many openings, as it provides flexibility and support for White's developing pieces.

In the Van't Kruijs Opening: Keoni-Hiva Gambit, Akahi Variation, Black responds to White's Nc3 by playing Nf6. This move develops the knight and puts additional pressure on White's pawn on e4. The knight on f6 also has the potential to jump to g4, where it can further disrupt White's control of the center. Additionally, playing Nf6 prepares for Black's future castling, which will bring the king to safety and connect the rooks. In sum, Nf6 is a solid developing move that puts pressure on White's position.

With the move f4 in response to Black's Nf6, White is seeking to attack Black's center pawns and create more space for their pieces. f4 furthers the control that White has over the e5 square, and also prepares for the possible expansion of White's pawn chain with e4. This move also opens up the possibility for the White bishop on c1 to be developed to f4 in the future, putting additional pressure on Black's pawn on e5. In sum, f4 is a strong move that sets the stage for White to continue developing their pieces with a strong presence in the center of the board.

In response to White's f4, Black can capture the pawn with exf4, which immediately challenges White's control of the center. This move also puts pressure on White's knight on c3, potentially forcing it to retreat or be exchanged. By capturing the pawn, Black creates an isolated pawn on e5, which can be either a strength or weakness depending on how well it is protected. Additionally, capturing on f4 allows Black's light-squared bishop to be developed to c5, where it can further pressure White's center pawns. In sum, exf4 is a bold move that seeks to challenge White's position and create opportunities for Black to gain an advantage.

In the Van't Kruijs Opening: Keoni-Hiva Gambit, Akahi Variation, White responds to Black's exf4 with Nf3. This move develops a piece and also defends the e4 pawn, which could otherwise be captured by Black's knight. Nf3 also puts additional pressure on Black's pawn on e5, further limiting Black's control of the center. Additionally, the knight on f3 is in position to support White's future pawn advance to d4, which would further increase White's control of the center. In sum, Nf3 is a strong and flexible move that sets the stage for continued development and pressure on Black's position.
