Any simple blunders that a beginner like me could miss?


When studying chess, you should at the very least know the basic traps on the opening that you play. For example if you have the white pieces and play 1.e4 e5 2.Nf3 then black replies ...f6?? (blunder) you should know the reply is 3.Nxe5 and you should study the continuation. There's so many opening blunders and knowing them is a good thing. Blunders in the opening and how to effectively study them is another topic.


When a piece is moved far away, it’s still dangerous.
When a knight moves off it’s square, don’t occupy that square, it’s still threatened.
Yes, I probably suffer from a lack of object permanence. But, I feel these are very very simple blunders that utter beginners make.

What time limits do you normally play?
you have to get used to identifying checks, threats, captures, strengths, and weaknesses for both sides. It’ll take a while to start but then it’ll feel more comfortable to make moves quicker after going through your check-list (get it??)
in all seriousness, make sure a square you’re trying to move to is safe, and playing longer times will allow your board awareness to improve. There’s 64 squares on a chess board, so if you’re only looking at 16, you’re doing something wrong

This is a game that you actually played
7. Ne5 is a horrible blunder, simply loses the knight for nothing.
10. b3 again loses material, because black can simply play Nxc4 and then Bxa1. The Nxc4 move is a discovered attack on the a1 rook.
12. Nc3 is bad, the same discovered attack still works.
13. Rd4 is the worst move ever, simply throwing away the rook for no reason.
Conclusion: you seem to play random moves without thinking. Don't do that. Use your time and think, try to play good moves.
