Improving Your Chess - Resources for Beginners and Beyond...

Dear Joker,

I am a certified, full-time chess coach, so I hope I can help you. Everybody is different, so that's why there isn't only one general way to learn. First of all, you have to discover your biggest weaknesses in the game and start working on them. The most effective way for that is analysing your own games. Of course, if you are a beginner, you can't do it efficiently because you don't know too much about the game yet. There is a built-in engine on chess.com which can show you if a move is good or bad but the only problem that it can't explain you the plans, ideas behind the moves, so you won't know why is it so good or bad.

You can learn from books or Youtube channels as well, and maybe you can find a lot of useful information there but these sources are mostly general things and not personalized at all. That's why you need a good coach sooner or later if you really want to be better at chess. A good coach can help you with identifying your biggest weaknesses and explain everything, so you can leave your mistakes behind you. Of course, you won't apply everything immediately, this is a learning process (like learning languages), but if you are persistent and enthusiastic, you will achieve your goals.

In my opinion, chess has 4 main territories (openings, strategies, tactics/combinations and endgames). If you want to improve efficiently, you should improve all of these skills almost at the same time. That's what my training program is based on. My students really like it because the lessons are not boring (because we talk about more than one areas within one lesson) and they feel the improvement on the longer run. Of course, there are always ups and downs but this is completely normal in everyone's career.

I hope this is helpful for you. Good luck for your chess games!

I have checked just one game, your last.

Your opponent attacks your knight with 5. e5, and instead of moving it away, you let them take it.

Later an even more amusing story, on move 14-16. Your opponent attacks your queen on e7, so you move it away. Then your opponent attacks the queen again, so you move it back to e7, the square that is still attacked.

So, one advice: try not to hang your pieces like that. As long as you make such obvious blunders, nothing else matters.

Slow down and check for the basics, what pieces can be taken, etc. Hanging material is the #1 issue I see in lower rated games.

Check over your games for those mistakes afterwards. Are you hanging material? Did you take hanging material when offered?
