No blitz plz i suck at blitz lmao,

Here’s to give back to the community

d4 or e4?

E4 but its based on preference

how much do you practice chess in a day?

I suck at E4 idk how play with E4 I only know D4 now I DO KNOW Openings with E4 and played E4 for a year but I now only play D4 in almost everything

If I had a coach I would need them to teach me E4

Caro-kan or Scandinavian?

1-2 chess games, and i try to puzzle rush and do some hard puzzles and a daily puzzle, i also analyse my games and read up a chess concept a week. I then try to apply the concept throughout the week.

If you are comfortable in D4, you have no need to learn E4. Although many joke about D4, after all it is just a joke and D4 is not bad as an opening.

Both have pros and cons. You should play a few games with both openings and see which you prefer more. You can watch Caro kann speedruns or Scandinavian speedruns by top-level streamers. That's how i decided on Caro kann, I simply preferred playing from the caro position. But both are solid!

Please can you guys stop putting pawn moves in capitals? It hurts my eyes

can you tell me some concepts that you are currently studying?

I'm looking at trying to make small advantages in the future. 
An example game is https://www.chess.com/game/live/128513568513 
where i beat an FM! On move 6, I didnt make the best move but I played d6, so as to conserve my d pawn and create a future pass pawn. It may not be the best move against Stockfish, but that pawn won me the game, my best game I played. I can say with confidence this method will definitely work for players at all levels.

Meant to say d5!

Another concept that helped me win that game was to restrict my opponents' pieces with pawns

thanks, I get the feeling of what to.

'Neutralizing'

How to improve thinking skills? I as a almost 1600 rated player blundered winning positions in rapid games. My kryptonite is "Winning a winning position". How do I practice to overcome the weakness?
