puzzles have made me realize that I can’t improve in chess

Have you played chess (and especially puzzles) before chess.com? I ask this sincerely, since you've only joined chess.com about a month ago and this is not even close to enough tactics to plateau your life-time chess potential. It is more likely, you are either going about tactics/puzzles incorrectly, or over-emphasizing their importance in chess. Here are a few possibilities/thoughts to consider:

- Quality over quantity is key here; the best way to really learn from each puzzle is to take your time and understand it more than rushing through a bunch quickly. I always want to analyze my incorrect puzzles right away to see not only the correct solution, but why I chose the wrong one and how I should have approached the puzzle.

- Check your stats to see how many you are solving correctly. @GothamChess recently recommended in a video, that 60% correct is approximately what you should strive for at least; if you do this, then your puzzles rating will likely go up. I'm guilty of not getting this many correct myself. I get about 50% of my puzzles correct (slightly more as of now, but not quite 60%+), so that means I should take my time on a few more puzzles than I am and go more for accuracy. 

- Puzzles should be fun! This is an important one. Some people do them habitually out of training but dread them all. Training doesn't have to be boring or grueling. Try mixing things up perhaps. Play puzzles (tactics), solve the daily puzzle, do puzzle rush on chess.com: 3 min, 5 min, and survival. All of these are different and so maybe you'll just do better at one over some other formats. For example: maybe someone is really good at survival mode of puzzle rush, but bad at the 3 min puzzle rush because they feel rushed. 

- Try to calculate the entire problem (or as much as you can decently) before moving any piece(s). This improves your calculation ability and also makes it more likely you'll understand the entire problem/ideas if you solve them this way. 

- Finally, even if you are bad a puzzles in general - this doesn't always mean you are bad at chess. The saying that chess is 99% tactics is laughable. It is an insult to endgame, opening theory, middlegame motifs, strategic planning, piece coordination, imbalances, weak squares...

okay you get the idea...all of that stuff I named and more clearly make up way more than 1% of chess. Tactics can be a useful way to improve big results in a short amount of time, but tactics alone isn't going to make you become a chess master. Chess masters reach those levels by a ton of other things and use puzzles like a training routine or warm up, but puzzles are not equal to the game of chess itself

this does not help as I have found some of the puzzle solutions in chess.com include an illegal move. ie. a pawn moving diagonally to a clear square!

Bro that's en passant. Learn the rules before you complain. There are no bugs in the chess.com puzzles.

very occasionally there are mistakes. but yeah, en passant isn't one

the number of puzzles doesn't matter a lot, it matters if you're actually trying to do them and reviewing the concepts. it also helps if you try to review your games and identify tactics you or your opponent missed, then train the tactics in puzzles (you can choose puzzle themes in the unrarted puzzles). It takes time and patience, but it is one of the keys to improvement

Don't play puzzles here - there are better sites.

note that this post is 2 years old and idk if OP still has the same concern...

weird attempt at spamming....it's very clear from the url what is going on
....but yeah, now I understand why chess.com blocks links at times

Play slower chess - playing blitz to see who leaves pieces hanging is not the way to get better. Blitz applies the experience gained by a lot of slower chess.

Can we look at the date before posting plz?

ikr LOL

Hyperlinks in the forums are okay, but advertising is not allowed when it crosses over into spamming. Generally, advertising things like chess.com clubs or YouTube channels are allowed as long as it is tastefully done and even better than a forum thread is to advertise in a blog post.

Anything more than this is spamming and not allowed. Advertising competing chess sites is also not allowed etc.

I might have missed some things, but that summarizes it; just use common sense and better judgement.

Also, to "prove" that hyperlinks are okay, here you go...

Single word advice for you "practice"

Don't do puzzles at bullet speed.
Try to solve them with whatever time you need. Ensure that what you play is the absolute best move.
