NEW UPDATED OPENING LINE
[August 31, 2017] Updated Opening Line by Vadim Zvjaginsev:
Queen’s Gambit Declined, Ragozin Variation with 5. cxd5 exd5 6. Bg5 Nbd7 7. e3
[Line 252 : 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Bb4 5. cxd5 exd5 6. Bg5 Nbd7 7. e3]
From the initial position of this opening line, move 7… c5 is considered to be the best option for Black. White now has three good alternatives to the most common 8. Bd3, and they are: 8. Be2, 8. dxc5 and 8. Bb5.
In case of 8. Be2, Black should proceed with 8… Qa5 9. O-O c4, with the idea of Bxc3 and Ne4, exerting pressure on the c3-pawn.
Against the second of the three recommendations (8. dxc5), Black gets a decent counterplay with 8… Qa5 9. Rc1 Bxc3+ 10. bxc3 O-O 11. Nd4 Qxa2.
The same Queen move is a also good reaction against 8. Bb5, as the position arising after 8… Qa5 9. Bxd7+ Nxd7 10. O-O Bxc3 11. bxc3 O-O should be considered roughly equal.
The main line goes 8. Bd3 Qa5 9. Qc2 c4 10. Bf5 O-O 11. O-O Re8 12. Nd2 g6, where against both 13. Bh3 and 13. Bxd7 Black has sufficient resources to reach the equality.
[Diagram: White to Move] White gets a slight edge after 13. Be5, but there is a better option that should promise him a considerable advantage. Can you find the superior plan?
