Bishop's Opening: del Rio Variation

In the Bishop's Opening: del Rio Variation, White starts with the move e4, aiming to control the center and develop the king's pawn to a strong position. This move also creates opportunities for White to bring out the bishops and knights, and start a coordinated assault on Black's position. By controlling the center, White can limit Black's mobility and make it difficult for their pieces to find good squares. Additionally, e4 creates the possibility of a pawn push to d4, which could open up lines and create more space for White's pieces to operate in.

After the move 1.e4 from White, Black commonly responds with e5, in order to also control the central squares. This move aims to mirror White's game plan, which plans on controlling the center with its pawns. Moreover, e5 also gives Black's knight and bishop the possibility to be developed into active square on f5 and c5 respectively. By advancing e5, Black also intends to limit the movements of White's e-pawn. Fundamentally, this is a sound move that aims to contest White's control of the center and helps Black establish a balanced position in the game.

White's move Bc4 after 1.e4 e5 is a well-known bishop development, known as the Bishop's Opening. By moving the bishop to c4, White pins Black's knight to the queen and takes the first step in developing his pieces rapidly. Often this bishop hits down on Black's f7 square, which is one of the weak points in Black's position in the opening stage of the game. Furthermore, this move has the added benefit of freeing the f1 bishop to develop to either g5 or b5, if required. In sum, Bc4 is a sound move that helps prepare for White's next move and maximizes the control of the center.

In the Bishop's Opening: del Rio Variation, by playing 2...Bc5, Black develops the bishop to an active square where it supports Black's control over the central squares. This move also mirrors White's move of placing their bishop on c4. By placing the bishop on c5, Black adds pressure to the d4 square that is already being contested by the white pawn, making it difficult for White to continue developing their pieces smoothly. Additionally, Bc5 helps prepare for Black's future attack on f2, which can follow if White castles kingside. In essence, 2...Bc5 is a sound move that helps Black grow their control on central squares while keeping up with the pace of White's bishop development.

After the moves 1.e4 e5 2.Bc4 Bc5, White's move c3 creates a solid pawn structure and prevents Black's Knight from jumping into d4. By doing so, White effectively supports the center and prepares the queen's gambit pawn structure. This move also provides a means of controlling the d4 square, which helps facilitate White's development of their pieces. Additionally, c3 prepares for a potential pawn push to d4, which could release more space for white bishops to operate effectively. In summary, the move c3 is an effective way of consolidating White's position while causing disruption to Black's plans.

After the moves 1.e4 e5 2.Bc4 Bc5 3.c3, Black's move Qg5 aims to put pressure on White's central pawns and exploit the potential weakness caused by the pawn on c3. By attacking the g2 square, Black poses a serious threat to White's kingside positional security and puts their king in an uncomfortable position already. Moreover, Qg5 causes White's bishop to move away from the c4 square, which decreases the pressure on Black's f7 pawn. Additionally, the queen on g5 is now in a position to coordinate with the bishop on c5 to attack the pawns at d4 and e4. In conclusion, Qg5 prepares for further counter-strikes against White's position, while simultaneously putting White on the back foot.
