Queen's Gambit Declined: Tartakower
Also known as: Tartakower–Makogonov–Bondarevsky System, TMB System
The Tartakower System, also known as the Tartakower-Makogonov-Bondarevsky or TMB System, is Black's most dynamic way of handling the Queen's Gambit Declined. Rather than tolerating the passive light-squared bishop that plagues classical QGD lines, Black plays ...h6, ...b6 and ...Bb7 to fianchetto it onto an active diagonal. The result is a flexible, hard-fought middlegame long trusted by world-class players seeking counterplay instead of mere solidity.

Strategic ideas
The Tartakower is built around solving the QGD's oldest headache: the bad bishop on c8, hemmed in by its own e6-pawn. By playing 7...b6 and ...Bb7, Black develops that bishop to a long, open diagonal where it bears down on White's centre and kingside, converting a chronic liability into Black's most active piece. This single idea transforms the whole defence: in place of the absorb-and-hold approach of the Orthodox, Black plays for piece activity, central tension and genuine winning chances with the black pieces.
The concrete structures that arise give the Tartakower its bite. If White exchanges with cxd5 and Black recaptures ...Nxd5, a wave of trades often leaves Black with the freeing ...c5 break and a fluid game; if Black recaptures ...exd5, play resembles a Carlsbad but with the bishop already outside the pawn chain. Most characteristically, a later ...c5 and the exchanges that follow can produce mobile hanging pawns for one side or an isolated queen's pawn for the other. Judging when those hanging pawns are strong and mobile rather than weak and overextended is the core skill of the entire system.
Main variations
From the tabiya 7.Bh4 b6, the main line runs 8.cxd5 Nxd5, when 9.Bxe7 Qxe7 10.Nxd5 exd5 reaches a clean structure in which the bishop on b7 supports the coming ...c5 break. An important older try is 8.Be2 Bb7 9.Bxf6 Bxf6 10.cxd5 exd5, when Black accepts a small structural concession in return for the bishop pair and easy, active development. White can also decline the exchanges and play classically with Rc1 and a later minority attack, but the fianchettoed bishop on b7 makes that plan far less comfortable than it is against the Orthodox.
Black's play then hinges on the ...c5 break: after ...c5 and the resulting captures, Black may saddle White with an isolated d-pawn or take on hanging pawns in exchange for open lines and active rooks. A key alternative keeps the tension, with Black manoeuvring ...Nbd7, ...Rc8 and ...c5 at the ideal moment to maximise the bishop on b7. Because these positions are so rich and double-edged, the Tartakower has served as a fighting equaliser at the very top - a way to unbalance the game without abandoning soundness. It contrasts sharply with the simplifying Lasker Defence, which trades pieces to bleed the position dry rather than to sharpen it.
History and background
The system is named for Savielly Tartakower, one of the most inventive masters of the hypermodern generation, together with Makogonov and Bondarevsky, who helped develop and popularise the ...b6 fianchetto plan. From the mid-twentieth century onward it earned a reputation as the most respected dynamic answer within the QGD, becoming a favourite of several world champions and elite grandmasters who used it to fight for the initiative with Black. Its blend of classical soundness and modern activity keeps it firmly in the repertoire of ambitious defenders to this day.
Key ideas
- Black plays ...b6 and ...Bb7 to develop the traditionally bad light-squared bishop actively.
- The fianchettoed bishop rakes the long diagonal against White's centre and kingside.
- The thematic ...c5 break challenges d4 and opens the position for Black's active pieces.
- Exchanges around c5 and d5 can yield mobile hanging pawns or an isolated queen's pawn.
- Black seeks real counterplay and winning chances rather than the passive solidity of the Orthodox.
- White must reckon with active defence, so a routine minority attack loses much of its sting.
Typical plans
White
- Exchange with cxd5 and answer ...Nxd5 by trading on d5 to reach a clear structure.
- Restrain the ...c5 break and pressure the resulting hanging or isolated pawns.
- Develop harmoniously with Bd3, O-O and Rc1 to contest the c-file.
- Aim for e3-e4 or piece pressure to blunt the black bishop on the long diagonal.
- Keep the tension when a minority attack is defused by Black's active setup.
Black
- Fianchetto with ...b6 and ...Bb7 to activate the light-squared bishop.
- Prepare and execute the ...c5 break at the ideal moment to free the game.
- Use ...Nbd7 and ...Rc8 to support ...c5 and pressure the c-file.
- Accept hanging pawns when their mobility and open lines outweigh their weakness.
- Recapture ...Nxd5 to invite exchanges that ease development and highlight the bishop.
