Help/Suggestions needed

I just played this game and i was black. I need help on what is the area i need to work on the most(middle game, end game, openings, tactics etc)? All help is appreciated this is my first post.

You need help with opening principles, and with very obvious tactics, like not placing pieces where they can be lost immediately without any compensation (17...Nexd5?? 18. Nxb5).

Some examples of opening principles you need to know:

Don't move out a bishop to create a pin (4...Bb4) if you're just going to retreat it as soon as threatened (5. a3 Bd6), unless you know what you're doing.

Don't block your central pawns with pieces (5...Bd6), unless you know what you're doing.

Capture pawns with pawns when they challenge each other in the center (11. d4 exd4) to prevent your pieces from getting chased off (12. d5 Ne7), unless you know what you're doing.

TY man hey that was good help appreciate if you could give me feed back in the future ty.

You're welcome. I'm surprised others haven't volunteered more advice here yet.

I offer  a national master that offers chess lessons. Email me at erabin66@gmail.com or see www.premierchess.com to learn more.
