How to not blunder

Hello, I am rated around 900 in rapid. I have gained around 200 points over the past couple months. My problem is one day I play really good games, and the next day, I make 5 blunders in one game. I'm not distracted or anything, I feel the same but my chess game is just off. Does anyone know anything that could help me with this?

There is an anna cramling video about that on youtube

check her channel and watch it

If you never play chess, you'll never blunder in chess ......

the checklist for you and opponents to (checks, captures, attacks)

middlegame plans help see the chesstalk video

positional chess can get you to 1300 easily 'cause it did with me

there are many videos like Gotham chess's old videos (the best opening ever x 2) and chesstalk, chessbase india, chesscape and more

i forgot to mention alessia santeramo, hikaru, and magnus,

yeah

all this will help get to 1550 and even beyond

Today i got 24 blunders on one of my games

Congrats

Thank you all for the advice.

My late father used an expression to describe this life phenomenon (good one day, bad another day). Some days, you get the bear, and some days, the bear gets you. It's just part of life. Good luck!

fischers golden rule helped me increase my rapid rating a bit.

You move too fast!!! You're playing 35, 45, and 55 move games at a 10 minute time control and at the end of the game you still have more than 5 minutes left?! Nobody moving that fast will benefit from any other advice than to slow down!

If you don't have any pieces, you cant blunder them .....

Chess requires using your brain. Every day life, for the most part, doesn't require much brain power unless you are in a field that requires logic or critical thinking, e.g., Math, Engineering, Law, etc. Since people are normally auto piloting around and not thinking very much I don't think they realize how much of an impact their emotions, sleep patterns, diet, etc. has on their ability to think. While this may seem counter intuitive, your issue with consistency, and the solution to this issue, may not have anything to do with chess.

I have found that my brain is the "freshest" shortly after waking up and slowly declines throughout the day. Perhaps before playing chess try and assess whether you are in the "right" mindset to be able to quell your emotions and focus on the game. If it isn't the right time, don't play. Turning off all devices and meditating for a few minutes before hand and getting your brain in a calm state may help too.

I know it sounds foo-fooy, but humans are complex systems. The manifestation of a symptom isn't always where the focus should be.

i have no idea how that is possible

Post the link.

I found GM Igor Smirnov's free master class very helpful. Search him on youtube and you should be able to find it.
