Always check your intended move is no blunder before you play it.
You intend a queen move.
Do not play it, but imagine it played on the board.
Now check it is no blunder: can some rook take it?
Only then play it.
This little mental discipline alone is enough to reach 1500.
I just can't stop being in poor form and it's been going on for over a week. Taking breaks isn't helping. I was 1083 and tilted all the way to below 1010.
I can do other things just fine such as playing stringed instruments but I am apparently too hopelessly mentally disabled to do basic things like not stick a queen where a rook can get it.
I'm thinking of quitting because chess pisses me off too much.
