Van Geet Opening: Jendrossek Gambit

In the Van Geet Opening: Jendrossek Gambit, white starts with the move Nc3. This move indirectly controls the central square d5, as it eyes the e5 square and blocks the c-pawn. Additionally, Nc3 prepares for the eventual development of the d2-knight to e3 or d4, exerting more control over the center. This move also allows white to potentially threaten black's e5 pawn with moves like Ng5 or Qb3.

Black's move d5 in response to Nc3 aims to occupy the central square and control more space. This move also supports the f6-knight and allows the dark-squared bishop to develop to an active square. Moreover, playing d5 limits white's options to push his pawn to e4, as a central pawn push from white can be met with a quick capture and exchange with d4. Black's move d5 is a common response to Nc3 in many openings and helps to establish a pawn presence in the center.

White's move f4 after 1.Nc3 d5 is a provocation to black's pawn structure. This pawn thrust aims to control the e5 square for the knight or bishop and prepare a pawn break with e3 later, solidifying white's central control. Playing f4 also restricts black's pawn moves, as moving the d or e-pawn would weaken their position. Additionally, this pawn push often leads to a kingside attack, with the rook and queen supporting the f-pawn advance, forcing black to react carefully and be mindful of any possible tactics. In sum, f4 is a bold and aggressive move that attempts to seize the initiative and control more space.

This knight move attacks black's d4 pawn and clears the way for the f2-knight to move to g5, adding pressure to the weakened f7-square. By occupying e4, the knight becomes a powerful central force, potentially controlling squares in both black's and white's half of the board. This move also prepares for a pawn push to d3 in order to protect the e4 knight and solidify control over the center. Ne4 is a natural developing move that shows the importance of seizing and maintaining central control in chess games.

Additionally, f5 opens up lines of attack for the dark-squared bishop and potentially the rook on the f-file. This move also prepares for the g7-bishop to be developed to a more active square. Playing f5 is a common plan in many openings, as it can be a powerful pawn break that disrupts the opponent's pawn structure. However, black must be mindful of the potential weaknesses that may be created in their own position.

This move can also serve to provoke a pawn advance from black on the kingside, which may create potential weaknesses that can be exploited later in the game. In sum, the move Nf2 is primarily aimed at repositioning the knight and exerting more control over the center.

This knight move also prepares for the kingside castle, which can help to protect the king and create a more solid position. Moreover, by developing the knight to f6, black exerts more control over the e4-square and restricts white's knight from being developed to d3 or g5.

Additionally, playing c5 frees up the c7-square for the development of the dark-squared bishop, which can coordinate with the knight on f6 and put pressure on the weakened pawn on f4. The move c5 can also potentially undermine white's control over the d5-square, creating opportunities for future pawn breaks or piece maneuvers. In sum, c5 is an important move for Black that helps to establish a strong positional foothold on the board.
