In the King's Gambit Accepted: Bishop's Gambit, First Jaenisch Variation, the move e4 is an aggressive attempt by White to gain control of the center and achieve a strong position.

This move is followed by the capture of Black's pawn on f4, which further strengthens White's control over the center. Ultimately, White hopes to use their central advantage to launch successful attacks against Black's position.

The move e5 is a natural response by Black to White's opening move e4, as it aims to claim a share of the center and establish a solid pawn structure. With this move, Black creates a pawn chain that supports their pieces and restricts the mobility of White's pawn on e4. Additionally, the pawn on e5 also allows Black's knights to develop to c6 and f6, adding support to their center and preparing for future attacks. By playing e5, Black seeks to gain control of the board and set the pace for the game.

The move f4, also known as the King's Gambit, is a daring attempt by White to take control of the game right from the opening.

The pawn on f4 also puts pressure on Black's e5 pawn, potentially preparing for a later attack with the knight on f3 or the bishop on c4. However, this move has its risks, as it weakens White's king's position and can allow Black to gain an advantage if White is not careful. In sum, the move f4 is a bold and aggressive strategy that seeks to surprise and unsettle Black's position from the outset.

The move exf4 also creates a weakness in White's pawn structure with the doubled pawns on f4 and f2, potentially allowing Black to apply pressure on White's position. However, this move also comes with its own risk, as it exposes Black's position and could leave their king vulnerable to attack in the early stages of the game.

The move Bc4 in response to Black's move exf4 is a strategic development by White, which aims to control the center and prepare for future attacks.

By playing Bc4, White also prepares to free their knight on f3 and continue to develop their pieces in a coordinated manner.

The move Qh4+ by Black after White's development of the bishop on c4 is a tactical maneuver aimed at gaining time and creating threats. By attacking White's king and forcing it to move, Black aims to disrupt White's plans and gain control of the initiative. This move also puts pressure on White's position, potentially opening up lines for Black's pieces and creating weaknesses in White's pawn structure. However, this move comes with its own risks, as it exposes Black's queen and leaves it vulnerable to attack if not supported by other pieces.

By moving the king to safety, White aims to avoid any potential threats and stabilize their position. This move also allows White to prepare for possible future attacks with the rooks on e1 and h1, while also freeing up the g1 square for the knight. Additionally, by moving the king away from the center, White avoids opening up lines for Black's pieces and maintains control over the central pawns. In sum, Kf1 is a careful and measured move that seeks to consolidate White's position and prepare for the next stages of the game.

The move Nf6 by Black after White's King move to f1 serves a dual purpose in the tactical context of the game. Firstly, Nf6 develops Black's knight to a more central position while preparing to castle King-side. Secondly, Nf6 also puts pressure on White's e4-pawn that is still undefended after white moved king-side and allows Black to threaten to gain a good central control. By attacking the e4-pawn, Black can neutralize some of the advantage that was gained by White's opening gambit. In sum, Nf6 is an important move in the game as it both develops Black's pieces and puts pressure on White's position.
