[Event "Meltwater CCTF 2021"] [White "Carlsen,Magnus"] [Black "Aronian,Levon"] [Site "Chess24"] [Round "8.4"] [Annotator ""] [Result "0-1"] [Date "2021.09.21"] [WhiteElo "2855"] [BlackElo "2782"] [PlyCount "52"] 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 {The Nimzo-Indian Defense. If you want to avoid this line and if you know that your opponent plays the Nimzo or Queen's Indian. Play this sequence: 1. Nf3, 2. c4 then 3. Nc3. This is to not commit pushing the d pawn at early stage which transposes now to reversed Sicilian. While black plays reversed Rossolimo.} 4. a3 Bxc3+ 5. bxc3 {This is part of opening but sooner the c4 pawn will be targeted. If only the d4 pawn has not moved yet. Then it's different case.} b6 6. f3 Nc6 7. e4 d6 {The pawn structure of NImzo-Indian is solid rock, that is the main idea to exchange the f8 bishop as well as create queenside imbalance for white.} 8. Nh3 Na5 {The pressure at c4 starts. Learn from black's strategy.} 9. Bd3 Ba6 10. Rb1 Qd7 {Avoiding check.} (10... Bxc4 {If} 11. Bxc4 Nxc4 12. Qa4+ )11. Qe2 c5 12. 0-0 Qa4 {Thats it!!} 13. Bf4 Rd8 14. Bxd6 {Black is looking for ways to complicate the position since black king still at the center.} Rxd6 15. e5 Rd8 16. exf6 gxf6 17. d5 Bxc4 18. Qe4 Rxd5 {There is still danger for black here due to exposed king.} 19. Nf4 f5 {This is timely...pushing back the queen.} 20. Qe3 Rd7 21. Qe5 Rf8 22. Bxf5 {Now, GM Carlsen exchanged the rook at f1, sensing Bxe6.} Bxf1 23. Bxe6 fxe6 24. Nxe6 Nc6 {This is the winning move...this assist in protecting the king.} 25. Qh5+ Rff7 26. Re1 Rde7 {Black Resigned. The Nimzo-Indian defense is not easy to tackle if you are not prepared. GM Levon Aronian shared us how to play dynamic Nimzo-Indian even the World Champ GM Carlsen cannot escape losing.} 0-1
