Exchange Slav
The Exchange Slav begins after the moves 1. d4 d5 2. c4 c6 3. cxd5 cxd5. It is one of White's safest answers to the Slav, and is a favourite of players who want a symmetrical position, few risks and the extra move.

Why play the Exchange Slav?
The Exchange Slav takes the tension out of the centre on move three.
After 1. d4 d5 2. c4 c6, White exchanges on d5 with 3. cxd5. Black recaptures with the c-pawn, the pawns become symmetrical, and the c-file opens.
Unlike the main Slav, there is no new pawn structure to learn. White keeps the extra move in a level, symmetrical position and is the first to use the open c-file.
Black chooses between copying White in the Symmetrical Line, the waiting move ...a6, and an early ...e6 that keeps the light-squared bishop at home.
Symmetry cuts both ways. Black develops just as easily, and if White plays without a plan, the pieces come off and the game ends in a draw.
What White keeps is the chance to press for a long time with little risk. Once Black's light-squared bishop leaves c8, the b7-pawn often needs care, and natural moves can already cost material.

Why the Exchange Slav is good with the:
Extra move - In a symmetrical position, White is a tempo ahead and decides first where the game is played.
Pressure on b7 - Once Black's light-squared bishop leaves c8, an early Qb3 attacks the b7-pawn and adds pressure to d5.
One set-up - White can meet most Black replies with the same plan: knight to c3, bishop to f4 and pawn to e3.
Suited for - Patient players who like a safe position and are happy to press in a level endgame.

Why the Exchange Slav is good with the black pieces
Free development - With the c-pawn gone, the b8-knight gets c6, and the light-squared bishop comes out before ...e6.
Sound pawns - The symmetrical pawns leave White nothing fixed to attack.
Equal rights - Black can copy most of White's moves, and the open c-file works for Black's rooks too.
Suited for - Solid players who like simple development and do not need a sharp game to play for a win.
Strategy
Typical plans, pawn breaks, and key squares.
Main line with ...a6
White heads for c5 with Na4, a3 and b4, prepares e4 with f3, and takes the c-file with a rook.
Qb3 against b7
Black answers Qb3 with ...Na5, hitting the queen and covering b7, and ...Bd7 meets a check on a4.
Trifunovic Variation
Black gives up the bishop on c3 and brings a rook to c8, with c4 the key square.
Traps and tactics
Three traps: a loose knight, a pin on c6 and a poisoned pawn.
Themes
Mind the b7-pawn
Once Black's light-squared bishop leaves c8, Qb3 hits b7, so Black needs an answer such as ...Na5 or ...Bb4 ready first.
Race for the c-file
The c-file is the only open file, so the side whose rooks reach it first presses, and the rooks are often traded down it.
The extra move
With the pawns mirrored, White's only edge is moving first, so the fight is about using that tempo before Black catches up.
Pieces before pawns
Early central breaks with e4 or ...e5 usually cost material here, so both sides improve their pieces and break only when prepared.

FAQ
The Exchange Slav begins after 1. d4 d5 2. c4 c6 3. cxd5 cxd5. White swaps pawns on d5, the c-file opens and both sides keep the same pawn structure, so White's edge is the extra move.
Yes, especially for players who like clear plans. Both sides develop by the basic principles and castle early. The main danger at club level is the Qb3 attack on b7 once Black's light-squared bishop has left c8.
Yes. Engines rate the main lines as equal, so White takes little risk, but the symmetry also makes the position hard to win. That is why the line has a reputation for draws.
White tries to use the extra move in a mirrored position. The usual plan is to develop with Nc3, Bf4 and e3, put a rook on the c-file and look for pressure on b7 with Qb3.
The Symmetrical Line arises after 4. Nc3 Nf6 5. Nf3 Nc6 6. Bf4 Bf5, when Black copies White's set-up exactly. After 7. e3 e6, White chooses between quiet development with 8. Bd3 and the more direct 8. Qb3.
The Trifunovic Variation is 8. Qb3 Bb4 in the Symmetrical Line. Black pins the c3-knight and blocks the queen's path to b7, so White cannot simply take the pawn.
In both, White exchanges on d5 early. In the Queen's Gambit Declined Black recaptures with the e-pawn and keeps the c7-pawn, so no file is fully open. In the Exchange Slav Black recaptures with the c-pawn, the c-file opens and the pawns stay mirrored.
There is no single best line. Players who like symmetry can copy White in the Symmetrical Line, while ...a6 suits those who want ...Na5 ready against Qb3. An early ...e6 suits players who prefer a compact set-up.
Frank Marshall, José Raúl Capablanca, Alexander Alekhine, Mikhail Botvinnik, Vladimir Kramnik, Levon Aronian, Vassily Ivanchuk, Wesley So and Fabiano Caruana have all used it.
Choose 3. Nf3 or 3. Nc3 if you want to meet the Open Slav head-on and fight for the centre after ...dxc4. Choose the Exchange Slav if you want a low-risk position with simple plans and the extra move.
Play the Exchange Slav if you want a safe position in which you set the problems. Black has to know how to defend b7, and one slip in the opening can already cost material.
