Practice makes Pathetic
play unrated if the number bothers you.
hit the puzzles harder: when you get one wrong, review the solution until you understand it: building your pattern recognition up is the key.
until you stop dropping pieces & pawns for free, you're going to lose to everybody who doesn't. the idea is to stop & really try to look for the best move, EVERY move... maybe try slower time controls to give you more time to think. 5/5 or 10/5 are way better than 1/0 or 3/0 with that goal in mind. 🙂
Ask here in the forum! Show us some examples. You will maybe learn to look a bit more behind the analysis and we will learn, because wie have also to figure out why the analysis gives some moves bad notes so that we can explain it. Win win! Think it would be funny if you collect three or four examples and explain why you think different like the analysis.
That's why you have to analyse your games using just your brains first (although some people here with no brains will kindly disagree), and only after doing that to consult an engine to see what has gone wrong with your play AND your analysis.
