Scandinavian Defense: Modern Variation, Gipslis Variation

The opening move in Scandinavian Defense is e4. White aims to control the center of the board by freeing the way for the Queen and the Bishop on f1. This move is popular among chess players as it hinders Black's King's pawn development and opens up spaces for White's pieces. White's next move is exd5, which will result in the exchange of pawns.

Black's opening move in response to e4 is d5. This move is aimed at taking control of the center of the board and creating space for Black's Queen and Bishop on c8. It also puts pressure on White's e4 pawn and prevents the easy development of White's King's pawn. By advancing the d-pawn, Black prepares to exchange pawns and equalize the center control. Additionally, this move also creates potential for a pawn push to d4 later in the game, which can lead to a more aggressive position for Black.

White's next move in response to Black's d5 is to capture the pawn with exd5. By doing so, White aims to get rid of Black's pawn pressure in the center and develop the Queen's Knight to a more active square if Black recaptures with the Knight. The exchange of pawns also opens up space for White's light-squared Bishop to be developed. While White has given up the center pawn, the move exd5 has simplified the position and solidified White's control over the center.

In the Scandinavian Defense: Modern Variation, Gipslis Variation, Black's logical response to exd5 by White is to play Nf6. This move attacks White's e4 pawn which has been left undefended after the pawn exchange. It also helps to develop Black's Knight to an active square and prepares to castle kingside, further solidifying Black's position. By placing pressure on White's center, Black aims to control and limit the activity of White's pieces. Moreover, Nf6 development also supports the advance of the pawn to e6 which will help to further restrict any attempt by White on the center.

In response to Black's Nf6, White's natural move is d4. By doing so, White reinforces control over the central squares and prepares to develop the light-squared Bishop to f4 or g5. d4 also provides support to the c3 Knight which can move to e4 later on, putting pressure on Black's position. White's pawn move aims to restrict Black's pawn push on e6 and block Black's Bishop on c8. The pawn on d4 provides an outpost for White's pieces on e5, which can be an excellent square for the Knight to dream of advancing with. In sum, d4 solidifies White's center and helps to maintain an advantage in space and activity on the board.

In this variation, Black's response to White's d4 is to capture the pawn with Nxd5. This move attacks White's Queen and opens up space for Black's dark-squared Bishop to be developed, either to g7 or e7. It also reinforces Black's control over the center of the board, preventing White's pawns from advancing and limiting the activity of White's pieces. By exchanging the Knight for White's pawn, Black can establish a pawn majority on the queenside while maintaining flexibility with their pieces. Furthermore, this move strengthens Black's Knight on f6, providing greater control over the striking square d4 which White would like to advance with their pawn.

In the Scandinavian Defense: Modern Variation, Gipslis Variation, White's next move is Nf3. The move develops the Knight, eyes the pawn on d5 and prepares to castle kingside. Furthermore, Nf3 adds support to the pawn on d4 which offers a solid control over the central squares. The move creates a threat on Black's Knight on d5 which might be captured and potentially create doubled pawns for Black. Additionally, the Knight on f3 provides pressure on Black's pawn on e5 once the pawn advances, with an attack on the pawn by a subsequent move of White's pawn on d4. Finally, the move Nf3 also allows White to easily develop the Bishop to e3, preparing for a later pin on the Knight on f6.

In this variation of the Scandinavian Defense, Black's move is to play Bg4. By pinning the Knight on f3, Black prevents White from castling kingside and creates the possibility for a tactical sequence which will disrupt White's position. Additionally, Bg4 puts pressure on the pawn on e4 and blocks the development of White's light-squared Bishop. The move also prepares to retreat the Bishop to h5, adding extra pressure on white's pawn structure. Finally, with the Bishop outside the pawn chain, Black can advance their pawn on e6, making the pawn structure more flexible and creating potential for the Bishop to develop further. Moreover, Black's Bishop also eyes the h2 square, which, if White castles on the queen side, can become a target for black in certain scenarios.
