how to get to 600 elo

Castle early, but please check if your backrank looks weak (mainly in short castling) back when I was like 400 this was probably the biggest mistake I made, if you give your king luft using the g pawn, be careful to not let the queen and bishop beside it for a checkmate attack) At your level if your opponents opposite side castle just keep bringing two or three pawns forward (make sure something is defending them, this is called pawn storming) at your level I doubt your opponents could sufficently defend, and their king will be weak, then just cut off squares. Playing bullet and blitz is fine for fun, but it doesn't tend to be efficent for improvement, so when you want to seriously practise do rapid (15/10 if you have time, 10 min if not)

I recommend you learn basic chess principles, and also commit to doing more puzzles. Since Chess.com doesn't let you do more than 3 puzzles per day without premium, you can either consider being a diamond member or you can check out an alternative site/app

Whenever I start working with a new student who is stuck at a plateau, 9 times out of 10 they are playing 20 blitz games a day and doing zero deep analysis of their losses. Swap to playing just 2 rapid games a day, but spend 15 minutes analyzing each game on your own before checking the engine. Your rating will thank you.

Salve, at your level, improvement comes from mastering two pillars: 1) tactics; 2) basic principles. Avoid diving deep into complex theory; your goal is to instantly recognize common tactical patterns. Master the basic motifs: forks (double attacks), pins, skewers, removing the defender, and discovered attacks. As for the opening phase, follow these 3 "golden rules": 1) control the center; 2) develop your pieces quickly; 3) keep your King safe. Don't move too many pawns, don't develop the Queen too early, don't forget to castle. Now the "phase 2": you must train your brain to apply it over the board. The plan: 1) go to "Analysis" board , right after the game; 2) turn on the engine evaluation; 3) step through the game move by move; 4) classify your mistakes. Actively check for these in your games: 1) hanging pieces; 2) missing opponent's threats; 3) neglecting King safety; 4) rushing and not thinking. Let's come to "phase 3": 1) play games with a purpose; 2) play longer time controls (15|10 or 30|0 are better for learning than 3-min bullet); 3) play to learn, not just to win; 4) limit "tilt" play (if your tired or frustrated after a loss, take a break instead of immediately playing another game in a bad mental state). And remember, progress is not linear, this is normal, your not alone, patience is the key. The goal is to become a better "thinker" and enjoy the game more deeply. Celebrate small victories, like "I did not hang a piece!" or "I used an opening principle correctly". Final recommendation: start your daily puzzle routine and review your very last game with methods above. It's all about building the habits. Ciao !

Lose a bunch of games and you'll go from 1000 to 600.

What is the Best opening for beginners?

Tactics are the foundation of chess. You need learn the most common themes and then drill them. Chesscom has a lot of lessons that will teach you everything you need to know. If you want free resources then predator on the chessboard is a site that will teach you tactics and more importantly how to spot them.

To learn general chess principles you should watch John Bartholomew climbing the rating ladder on youtube. Other good ones are Aman Hambleton and Daniel Naroditsky speedrun series. You'll learn how masters play in a way that's accessible no matter your rating.

For beginners I would recommend openings like the Italian game and the Queens gambit for white, and basic e5 and d5 or maybe the Caro-Kann for black. Stay away from complex openings like the Ruy Lopez and Sicilian as they involve a lot of deep theory and memorisation. It is more effective to learn basic openings and understand why you are making moves, not just memorising them. Hope this helped.

Salve, there is not a single "best" opening, but for most beginners the strongest choice is: 1) Italian game or Scotch game for White (these give you a solid structure, and lots of tactics practice) if 1.e4 (if you prefer 1.d4: London System or Queen's Gambit) ; 2) for Black, against 1.e4: Caro-Kann Defence (probably the single best beginner defence against 1.e4); against 1.d4 (for Black): Slav Defence (solid and straightforward development, good for learning plans) or "QGD style" (Queen's Gambit Declined, classic and very solid, you'll learn a lot about positional play). You don't need more than this as a beginner; the goal is to learn principles, not memorize 20 moves of theory. And remember, what really matters most (more than the opening name) are basic principles, these are far more important. Ciao !

I get what you're saying, the Ruy Lopez does have a lot of theory but so does the Italian. The Queen's gambit is one of the deepest openings in chess with endless amount of theory. But like many openings beginners can still play them. Same is true with Ruy or Sicilian.

For beginners the most important thing is learning tactics, chess principles and a few main ideas in their openings. Not learning a specific opening. As long as they're playing a classical/sound opening beginners are fine.
