Queen's Gambit Declined: Mastering a new opening
As an alternative to the Czech Pirc, specifically against 1. d4, I recently experimented with the Nimzo-Indian Defense, which is considered Black's winningest reply to 1. d4. However, I repeatedly found myself in positions I couldn't understand and White was able to penetrate my defenses with ease. These experiences, together with the fact that I am a 1. d4 player myself, prompted me to seek counsel from a PDF booklet on the Queen's Gambit I had printed out early this year. Authored by Richard James of chessKIDS academy, the 11-page booklet gives a basic introduction to the Queen's Gambit and recommends studying one or all of seven opening variations. My goal in this report is to learn the mainline Queen's Gambit Declined and the Cambridge Springs Variation, with the understanding that at a later time I might add the Slav Defense to my repertoire.

| 1. d4 d5 |
With 1. d4 White occupies the central d4 square with a pawn protected by the queen, controls the central e5 square, and opens a diagonal for his dark-squared bishop. Given the opportunity, White will play e4 in the future, controlling both e5 and d5 and enjoying a superior position.
With 1...d5 Black establishes a presence of his own in the center. He occupies the central d5 square with a pawn protected by the queen, impedes the forward movement of White's d-pawn, controls the central e4 square so White can't advance his e-pawn pawn there, and opens a diagonal for his light-squared bishop. Black's symmetrical response means neither side has an advantage on the board after move 1.

| 2. c4 e6 |
With 2. c4 White is simultaneously attacking Black's pawn on d5 and enticing Black to capture on c4. In addition, White is opening a diagonal for his queen and preparing the move Nc3, since Nc3 before c4 would block the c-pawn's advance. If Black ignores White's attack, White can potentially play cxd5, removing Black's valuable center pawn from the board and gaining a major positional advantage -- not least because the move e4 would become playable, whereby White's pawns would control both e5 and d5. If Black plays ...dxc4, he wins material but vacates the d-file and still allows White to dominate the center.
With 2...e6 Black declines White's invitation to capture on c4 and addresses White's threat of cxd5 by defending his d5 pawn with the e-pawn. Ostensibly, White could make good on his cxd5 threat, for after 3. cxd5 exd5 White would have two central pawns to Black's one; but in reality White would have achieved nothing, since Black would still occupy d5 with a pawn and retain control of e4. A drawback of 2...e6 is that Black's light-squared bishop on c8, whose diagonal Black opened with 1...d5, is demoted to a passive position. On the other hand, 2...e6 opens the diagonal of Black's dark-squared bishop; and the development of this bishop is arguably a higher priority since it facilitates castling short as early as move 5. Lastly, 2...e6 creates a pawn chain, which is a longterm positional asset.

| 3. Nc3 Nf6 |
[Alternative: 3. Nc3 Be7 (Charousek Variation)]
With 2. Nc3 White begins challenging Black's control of the e4 square. At the same time, he adds a second attacker to Black's pawn on d5. 2. Nc3 is also in keeping with the adage "Knights before bishops," since c3 is a natural square for White's queenside knight early in the game but it is still too early to ascertain the best square for White's queenside bishop.
With 2...Nf6 Black reinforces his control of e4, continuing to prevent White from occupying the square with his e-pawn. At the same time, he adds a third defender to the pawn on d5 and a second defender to the pawn on h2, the latter of which typically becomes a target of White's light-squared bishop and queen. An added benefit of 2...Nf6 is that, unlike White, who cannot castle kingside until move 6 at the earliest, Black, since his kingside bishop already has an open diagonal, is prepared to castle after move 4.
 |
| 4. Bg5 Be7 |
[Alternative: 4. cxd5 exd5 (Exchange Variation)]
[Alternative: 4. Bg5 Nd7 (Cambridge Springs Variation]
With 4. Bg5 White relocates his dark-squared bishop to a destination that fulfills the opening principle "Develop with threats." The bishop attacks the knight on f6 and compounds the pressure on Black's position by undermining Black's defense of the pawn on d5. To wit, if Black disregards the threat of 5. Bxf6, he faces one of two outcomes: critical damage to his kingside pawn structure after 5. Bxf6 gxf6, or the loss of a pawn after 5. Bxf6 Qxf6 6. cxd5 exd5 7. Nxd5. Therefore:
With 4...Be7 Black unpins the knight on f6 and clears his kingside of minor pieces in preparation for castling short. Now 5. Bxf6 can be answered with 5...Bxf6: Black's kingside pawn structure remains intact and the pawn on d5 remains double-defended. It may seem as though White has been dictating the flow of the game and that Black's development has been reactive in nature; in reality, however, Stockfish considers both sides to be in a relation of virtual equality. Moreover, once Black's king is safely castled, his solid position will free him to explore attacking possibilities.

| 5. e3 0-0 |
With 5. e3 White links up his pawns on c2 and d4, establishing a dark-squared pawn chain, and opens a diagonal for his light-squared bishop. Now White's pawn on d4 is defended by the queen and by the pawn on e3, and the pawn on c4 is defended by the bishop on f1. 5. e3 does seal off the dark-squared bishop's preferred escape route from g5, but it is the best White can do given that e4 is not playable.
With 5...0-0 Black moves his king to safety and prepares to centralize one of his rooks. Black does need to keep in mind that he has committed his king to a side of the board where White already has an active bishop, is about to have an active knight, and will likely soon have a bishop-and-queen battery trained on h7. Vital for Black is to use the time White will spend developing his kingside to start pressuring White's position.
 |
| 6. Nf3 h6 |
With 6...h6 Black inquires of White's bishop on g5 what its purpose in life is. Namely, does it intend to exchange itself for the knight on f6? If so, Black will recapture with the bishop and have sole possession of the bishop pair, which could prove advantageous in later stages of the game. If not, the bishop will have to choose another square as its home. 6...h6 also anticipates the bishop-and-queen battery mentioned on move 5 by advancing the pawn off the square that will be said battery's target.

| 7. Bh4 b6 |
With 7...b6 Black prepares ...Bb7 and ...c5. As mentioned on move 2, a drawback of the Queen's Gambit Declined is that Black's light-squared bishop is prevented by 2...e3 from realizing its potential as a long-range weapon. 7...b6 begins addressing this issue by arranging a fianchetto square for the bishop. 7...b6 also gives Black control of the c5 square, to which Black's pawn on c7 can subsequently advance and attack White's center pawn on d4.
Move 7 is as deep as Richard James goes on the Queen's Gambit Declined in his PDF guide. In my experience as a 1300-rated player on Chess.com Rapid, it is rare for a game to go seven moves and look exactly like the game theorized there. Rather, it is grasping the reasoning behind the moves that is key -- that and understanding the players' longer-term plans as they transtion from the opening to the middlegame.
What are the players' longer-term plans? Kostya Kavutskiy of Chess.com offers some ideas in a short video available on YouTube.
