How can I further improve? (expert opinion???)

There is no better or more efficient way to improve at anything lol

And why would that be?

I've seen some threads here from people who played hundreds of games and still think capturing a pawn en passant would be cheating or a glitch on the web site. I think that proves @B1ZMARK's point. 

Easy to say, but if you think about it, it's such a dumb phrase. If you took it seriously and literally, you weren't even able to  start a game! There are no tactics in the first moves, unless someone makes a  strategic or positional  blunder. 

You will need to work at it for 10,000 hours to master it!

@sir_mad_alot - lots of helpful stuff for you here.....check it out...

I want you to close your eyes and imagine the thing you desire most..ok keep them eyes shut.. keep imagining it... Next I want you to imagine your most desirable person hawking up a big loogir and spitting it into the ocean off a helicopter, that's what you are, that's why you can't get better. You're just a drop of spit in the ocean,. Just kidding buddy, If you want to improve, start mimicking what people about 300 points higher than you are doing. Learn to Void traps, keep losing it will make u win eventually if u r reflecting, it's your mind that God gave you, u can do it

Alright. I suggest learning what makes a good position, how to defend a bad one (this is quite complex, do this later down the road), and doing puzzles. I highly recommend The Woodpecker Method by GM Alex Smith, if I got his name correctly.

I totally agree with you, bro. Especially after what he said in his second comment.

Glad my topic could help you too. I sometimes post here to get some ideas and motivation. And rating drop is pretty normal. I myself recently reached at 799. But then it dropped back to around 600. Took me about a week to surpass 800 barrier. Don't worry it only gets better. You just have to learn from your mistakes and keep exploring. Keep it up!!! 

I agree with the 3 pointers from bluemu. Keep training puzzles puzzles puzzles imo. There's madness to the method in the end. Pay particular attention to forcing lead-up moves, pins, removing defender, and over-worked defenders. When you start seeing how to force your opponent do this or that you start to be able to formulate plans more readily, and when the opportunity to skewer/fork arises, you were aware that it likely would, and you don't overlook it. I've had a bit of an epiphany recently myself. Did you know there are puzzles where the correct answer is 'push a pawn?' :0 It feels quite zen to evaluate a board and try to run through attack sequences, move order switcheroos, check options, and finally go, 'The best move is just push that pawn.' And all it does is maintain equality. And then you do it. And it's RIGHT. :0 Eventually, you start to see...

There are thousands of books on chess.  I have a friend that has an entire wall of a long hallway filled with shelves of chess books from floor to ceiling.

One good chess book read and understood well is worth a hundred just owned and skimmed through.

At your level, you could probably use a good education on basic end games.    I like the Pandolfini book.

Oh, thanks a lottt!!! It really means a lot coming from an accomplished player like you. & yes I'm definitely going to try some chess books.

OP, you probably should have asked in the beginner's (class) forum. You'd have gotten more helpful replies and less trolling ones.

It's common to hear someone say that they've been studying tactics but can't find them in their own game. That's probably because you've just been doing tactic puzzles, but haven't studied any solving strategies that help you find tactics. Look online or search the forums for check, take, attack. You want to look for forcing moves: check, mate threats, attacking pieces with a higher value, attacking undefended or insufficiently defended pieces.

As for studying: keep it up with tactics: your own games are still decided by them. In addition try and learn what 'normal' moves look like, so that you can make a normal move when there is no tactic. Study a bit of the middlegame for that. I wouldn't touch any of the dynamic stuff at your level though (so no initiative, lead in development play etc).

Agree to disagree … Other than the rules, you don’t have to study ANYTHING to start a game, but you do have to study tactics to end a game. 

Okay, that was funny. :-)
