Queen's Gambit Declined: Tartakower Defense: what should Black play?

c5! — Excellent Choice!

✅ One of 4 top moves — you found the most precise way to challenge the center!

Why this move is excellent: By playing c5, you immediately strike at the white d4 and open lines for your pieces. Only 10% of players find this move, as most reflexively develop the bishop, but your choice forces White to address the central tension immediately.

Multiple Valid Strategies

This position is rich with options. While you chose the most active break, three other moves maintain the balance:

Different paths, same destination: Your move c5 is the engine's favorite because it prevents White from getting comfortable. While Bb7 is a "safety first" approach, your choice creates a more dynamic struggle where Black fights for the initiative.

Your Continuation

After c5, the game remains perfectly balanced: O-O Nbd7 Bg3 dxc4 Bxc4

What Made This Move Good

You correctly saw: That the d5 was under pressure and the best defense was a good offense. By attacking d4, you ensure that White cannot easily build a kingside attack without dealing with the collapsing center first.

📚 Takeaway: When you have multiple good options, choosing the most active one—like you did—often puts the most pressure on your opponent!
