On move 9, I missed the only move in a critical situation. I don't really understand why, can someone explain this to me please?

Also sorry if this is the wrong place to post for help, I wasn't sure. 

Hey there!

Honestly, I think that doing puzzles, understanding basic endgames by practicing against the engine, and just exploring more tactics are a good start. Along with that, I feel that coaching from ChessMood would be best for you as well: it worked for me too! If you didn't know, ChessMood is a great resource for players at all levels of chess learning. They have many free videos, articles, and challenges that break down chess concepts and overall strategies in an easy-to-understand way. Plus, their community is super supportive of learning players, so you can get tips and advice from others using this wonderful platform! I benefited extremely from this platform, so give it a try and you'll see the immense progress you'll make through this! Have fun!

In the diagram you will see a more in depth reason, but in short, Nd4 is much better than anything else, so everything else is inaccurate.

Thanks for the tip, I’ll try it out when I can
