Ruy Lopez: Schliemann Defense, Jaenisch Gambit Accepted

The Ruy Lopez is one of the oldest and most popular chess openings. It starts with 1.e4 e5 2.Nf3 Nc6 3.Bb5. This move is aimed at controlling the center with the Bishop and White plans to castle kingside. The idea behind the move is to create threats against Black's e5 pawn and discourage Black from advancing it. By playing Bb5, White also activates another piece and prepares to put pressure on the center. In sum, this move lays a solid foundation for White's opening strategy and sets the stage for a complex battle for control of the board.

When Black plays e5 in response to 1. e4, they are also aiming to control the center of the board. By advancing their pawn, Black gains more space in the center and creates a stronger foothold on the board. Additionally, this move opens up the way for the dark-squared Bishop to be developed, making it available for later use in the game. Black's e5 pawn can also put pressure on White's pawn structure, making it more difficult for White to mount an offensive. In sum, e5 is an effective way for Black to establish their presence on the board and prepare for further development.

When White plays Nf3 after 1. e4 e5, they are committing a knight to the board and preparing to develop their pieces. The knight placement also controls the center of the board, which is a key strategic objective in the opening phase of the game. With Nf3, White is also getting ready to castle kingside and reinforce the position of their king. This move is a standard response to Black's e5 and lays the groundwork for White's attacking strategy. Additionally, Nf3 also sets the stage for other possibilities such as pinning Black's knight or advancing the e-pawn to bolster white's pawn structure.

When White plays Bb5 after 1. e4 e5 2. Nf3 Nc6, they are starting the Ruy Lopez opening. This move develops the bishop and checks the knight, forcing Black to make a decision. The bishop also puts pressure on Black's pawn on e5, which could be a target for White to attack later in the game. Bb5 is a key move in the Ruy Lopez opening because it sets the stage for White to gain control of the center of the board and begin a coordinated attack against Black's position. By controlling the important d4 square, White is laying the foundation for a complex and aggressive game.

When Black plays f5 after the move 3. Bb5, they are initiating the Schliemann Defense, a very aggressive opening that aims to counterattack White's position. The move creates immediate threats on White's pawn on e4, which must be defended by a piece or another pawn. It also opens lines for the bishop to be deployed on the kingside, providing additional offensive potential for Black. While it weakens the position of their own King, the move creates a complex game where every move is critical and small advantages can quickly be turned into large ones. Ultimately, f5 is a bold and risky move, but one that can pay dividends for Black if executed effectively.

In the Ruy Lopez: Schliemann Defense, Jaenisch Gambit Accepted, White wants to play exf5 after 3. Bb5 f5. This move aims to drive Black's pawn from the center and gain material advantage by capturing it. It also creates a potential weakness in Black's pawn structure on f5, which can be exploited later on. By taking the pawn, White can open up lines for their pieces and start to put pressure on Black's position. However, the move also results in doubled pawns for White on the f-file, which can be a liability in the endgame. In sum, exf5 is a bold move aimed at gaining material and initiating an aggressive campaign against Black's position.
