Best way to improve your game?



It's good to analyze your own games and learn from them. You can also do engine analysis, but it is important to not trust the engine too much. You play a lot of blitz, which is fun, but you make bad habits. I would suggest you play more daily chess.
You can also look at top grandmaster games and see what type of moves they play and analyze them.
Anyway, let's take your latest loss. I won't point out all your tactical mistakes, and I will only annotate your moves.
I noticed you hang a lot of pieces. As I said, make sure to look at the whole board before making a move and be vigilant to your opponent's threats. This is the advantage of daily chess - you have lots of time to think and make sure you're not hanging any pieces.
Here is another game:
I notice that you let your opponent pin your knight to your Queen and that you didn't take any measures to get out of the pin. When one of your pieces is pinned, you want to break the pin as soon as possible.
Here is a video by ChessNetwork that further explains the power of the pin and what you can do to counter it.

"... If it’s instruction, you look for an author that addresses players at your level (buying something that’s too advanced won’t help you at all). This means that a classic book that is revered by many people might not be useful for you. ..." - IM Jeremy Silman (2015)

"... Sure, fast games are fine for practicing openings (not the most important part of the game for most players) and possibly developing decent board vision and tactical 'shots', but the kind of thinking it takes to plan, evaluate, play long endgames, and find deep combinations is just not possible in quick chess. … for serious improvement ... consistently play many slow games to practice good thinking habits. ... I know that a large percentage of my readers almost exclusively play on the internet - after all, you are reading this on the internet, right!? But there is a strong case for at least augmenting internet play with some OTB play, whether in a club or, better yet, a tournament. ... I would guess that players who have never played OTB usually gain 50-100 points of playing strength just from competing in their first long weekend tournament, assuming they play five or more rounds of very slow chess. ... Don't have two day? Try a one-day quad (a round-robin among four similarly rated players). … about 100 slow games a year is a reasonable foundation for ongoing improvement. ... Can't make 100? Then try for 60. If you only play three or fewer tournaments a year and do not play slow chess regularly at a club (or on-line, where G/90 and slower play is relatively rare), then do not be surprised that you are not really improving. ..." - NM Dan Heisman (2002)

You need to spend more time on analysis, better with no computer. That is the best, classical, most traditional way of improvement used by all serious players. Not just solving puzzles or reading books.

OTB is tough for me. I have to go across town to get it my chess club. I’m trying to make it a habit. I do indeed miss using real pieces. I have a few different chess computers. My latest is a dgt centaur which seems the most modern in terms of the engine. I also have my own MasterPiece chess pieces that can help me visualize my games better.
In the end, I think it’s about the post analysis and making good strategic thinking habits in game.
May the chess be with you.

If your opponent plays irregular openings, usually they are trying to throw you off. Don't forget the opening principles though.
(Courtesy of @IMBacon):
Opening Principles:
1. Control the center squares – d4-e4-d5-e5
2. Develop your minor pieces toward the center – piece activity is the key
3. Castle
4. Connect your rooks
Finally, here is a video from ChessNetwork on how to play the opening.

Here's a suggestion nobody has offered. Play yourself. That's how Bobby Fischer started as well as the greatest chess player in the world, AlphaZero.


Another suggestion which I have found quite useful is having someone to help you one on one. Obviously someone better than yourself who can teach you more than you already know.

You must leave the books behind, get out of your room and approach women. The more women you interact with, the more skill and confidence you will develop. This is how you improve your game.

If you've tried everything else, try watching GM tournament commentary on YouTube. I've learned some valuable lessons by watching guys like Yasser Seirawan and Danny Rensch analyze the games of the top GM's. You'll probably have to be around a 1700 or higher player to get a lot out of it though. Before I broke the 1600 barrier, I couldn't understand a lot of the GM moves. Now I do, so I watch every big tournament that has good commentary.

It's good to analyze your own games and learn from them. You can also do engine analysis, but it is important to not trust the engine too much. You play a lot of blitz, which is fun, but you make bad habits. I would suggest you play more daily chess.
You can also look at top grandmaster games and see what type of moves they play and analyze them.
I totally agree with Hammer. Playing blitz and bullet will not improve your game. Play daily games and analyze each one with Stockfish, after it's over. Also, try a regimen of 80-90% study and only 10-20% playing. There are tons of video lessons on YouTube that you haven't watched yet. I highly suggest watching Yasser Seirawan and Danny Rensch videos.
