A90 Dutch Defence: Miscellaneous and Modern Stonewall (with ...Bd6) (1.d4 d5 2.c4 c6 3.Nc3 e6 4.Nf3 f5 5.g3 Nf6 6.Bg2 Bd6 7.O-O O-O 8.Bg5)

This game is just one of many where the move order in the beginning of the game does not follow the theoretical path. Theoretical move order for this opening is 1.d4 d5 2.c4 e6 3.Nc3 c6. The game below was played in a team match called La Belle France vs Grupo Países e Regiões Lusófonos at Chess.com. The match was played on 11 boards and I played on board 4 for La Belle France. I was able to win my other game against agosoxo. I could have also won this game if I had not made a huge blunder on move 44. I made the move Nf6 because I thought that I will win in all variations, but of course I missed the obvious check 44...Qa7+, which is actually probably the only move that makes the move Nf6 a mistake. When I saw the move Qa7+, I was really disappointed in me for not seeing this move. I mainly looked the lines where my opponent takes on e5 in reply to Nf6 because I may care too much on not giving any material unless there is a good reason. The match ended with a score of 14 - 8 in favor of La Belle France!
