I actually suck

there is a reason I haven't been on this site in a while.

I LOST TO MARTIN BOT BRO

Opening principles. If you castled then this would not have happened and blunder check every move. When I move this then what can my opponent do? If they move there does it open up a piece behind it or attacking/put pressure on anything?

You made alot of knight moves and one way to stop this is to see that many of your other pieces is just sitting there doing nothing so my instinct is to find the best way to develop my pieces to good squares where they all support/defend each other. You could have done f3 before the mate which would have stopped everything entirely and f3/c3 is when the bishop goes to b4 or g4 unless the knight is already there, I’m not saying to not put the knight on f3 or c3, but I am just giving you the idea of f3 and c3 and this is where analyzing comes in. Analyzing can help you see mistakes you didn’t know you did for example blundering the knight in this example and seeing your blunder again can help you stop making that mistake. I’ll put my blog down below because I don’t have much time here.

Go here in this blog called Chess Tips, Annotated Games, And Openings and check what you may be looking for and I’ll be updating this when I get the chance to. It may say unfinished, but that’s just a technical issue. Read this only for those people who know I am on ios I managed to make this because in a club I found a blog link and I clicked and I found the option to make a blog.
