Queen's Gambit Declined: Lasker
Also known as: Lasker Defence
The Lasker Defence, named after world champion Emanuel Lasker, is the classical simplifying answer to the Queen's Gambit Declined. By interpolating ...h6 to question the g5-bishop and then playing ...Ne4, Black offers a series of exchanges that trade away the very pieces most cramped by White's spatial edge. The reward is a sturdy, low-risk game in which Black accepts a shade of passivity for easy development and clear equalising plans.

Strategic ideas
The Lasker's guiding idea is that exchanges are the road to equality. After 6...h6 7.Bh4 Ne4, Black strikes at the h4-bishop and the c3-knight at once, and the typical sequence 8.Bxe7 Qxe7 9.cxd5 Nxc3 10.bxc3 exd5 liquidates two pairs of minor pieces and clarifies the structure. Each trade relieves the chronic space disadvantage that makes the Queen's Gambit Declined uncomfortable, so Black gladly concedes a little time in return for a lighter, freer game that is far easier to handle.
Once the smoke clears, Black completes development with ...c6 or the more ambitious ...c5, aiming to free the queen's bishop and reach full equality. With so many minor pieces gone, White's attacking chances recede and the fight revolves around the pawn structure: White may still probe with a minority attack or occupy the open c-file, while Black neutralises with accurate rook play and timely central breaks. The trade-off is that Black's remaining pieces can feel slightly passive, and if Black drifts, the c8-bishop can remain the tell-tale bad piece of the QGD. Unlike the Tartakower, which cures that bishop by fianchetto, the Lasker frees it through exchanges and a later ...dxc4 or ...c5.
Main variations
The principal tabiya arises after 6...h6 7.Bh4 Ne4 8.Bxe7 Qxe7, when White must decide how to meet the knight on e4. The most testing try is 9.cxd5, and after 9...Nxc3 10.bxc3 exd5 11.Qb3 Black defends the d5-pawn and untangles with ...Rd8, ...c6 or the freeing ...c5. An older approach is 9.Rc1 c6 10.Bd3 Nxc3 11.Rxc3, when White keeps the pawn structure intact, swings the rook along the third rank, and retains a nagging spatial pull while Black steadily equalises.
Move order matters here: the immediate ...Ne4 is standard, but Black can first insert ...c6 or ...dxc4 to blunt White's setup. A recurring theme is the ...c5 break, which challenges d4 and, after mass exchanges, can leave White with an isolated queen's pawn or Black facing manageable hanging pawns. If Black keeps things quiet with ...c6 and ...Nd7 instead, the game resembles a calmer Orthodox in which the pieces short of squares have already been swapped off. Well-prepared players treat the Lasker as a dependable drawing weapon at the highest level precisely because its simplified positions are so hard to lose.
History and background
The defence carries the name of Emanuel Lasker, the long-reigning world champion whose pragmatic style favoured sound simplification over speculative complications. It became one of the classic recipes for neutralising the Queen's Gambit, admired for converting the QGD's spatial handicap into a manageable, low-maintenance structure. Over the following decades it earned a reputation as an ultra-solid equaliser, and modern grandmasters have periodically revived it when they need a reliable, hard-to-crack reply to 1.d4 in must-not-lose situations.
Key ideas
- Black plays ...h6 and ...Ne4 to force exchanges that relieve the QGD's chronic lack of space.
- The trades ...Nxc3 and Bxe7 remove the pieces most hampered by White's spatial advantage.
- After liquidation Black frees the game with ...c6, ...c5 or a well-timed ...dxc4.
- The ...c5 break can hand White an isolated queen's pawn or produce symmetrical simplification.
- Black concedes a little time and slight passivity for a simplified, hard-to-lose position.
- White fights for an edge with the c-file, a minority attack or pressure on the d5-pawn.
Typical plans
White
- Meet ...Ne4 with 8.Bxe7 Qxe7 and choose between 9.cxd5 and 9.Rc1 to keep an edge.
- Play cxd5 to open the c-file and target Black's d5-pawn after the exchanges.
- Develop the bishop to d3 and centralise the rooks to exploit the extra space.
- Probe with a minority attack of b4-b5 to try to create a queenside weakness.
- Keep enough pieces on the board so that Black's slight passivity tells in a long game.
Black
- Interpolate ...h6 and jump ...Ne4 to initiate the simplifying exchanges.
- Recapture with ...Nxc3 and clarify the centre with ...exd5 to ease the cramp.
- Free the position with ...c5, challenging d4 and activating the pieces.
- Alternatively play the solid ...c6 and ...Nd7 to reach a calm, durable structure.
- Use accurate rook play to neutralise the c-file and hold the simplified position.
