The puzzles on chess.com are not anything like the problems and endgames in a professional composition environment. Look at them as positions in games where nobody tells you where to go and how fast. Just find the best moves. All you know for sure is that (a) only one move is the clear best at every turn (b) if there is a quick mate you must find it.
Do not worry about the themes. They are often wrong and you need not care. As in a chess game you never know which theme to look for. Solving many puzzles trains your intuition to recognize patterns in a position with promising ideas/themes. Seeing them is not enough as you still need to calculate for success anyway.
Professional compositions have precise instructions (like "mate in 4") and precise definitions of many advanced themes you will not see on chess.com. Your puzzle training on chess.com won't help a lot when you go there. This is only training for games which is a lot more boring than the domain of compositions.
Btw, On the highest rating levels (2500+) chess.com wil present you occasionally with some composition level challenges. Things brighten up near the top!
Hey all, I've recently joined chess.com having not played chess for a solid decade or so, I'm easing in slow, going through the lessons I already know to make sure there aren't any basics I've forgotten or never knew, one thing I'm doing is my daily allocation of puzzles. Some of them are quite good, though I find the lack of initial instruction disturbing, e.g. "find mate in 2, find a material advantage in 4 moves, etc." The theme you're looking for seems to only appear after the puzzle has been solved, and when the themes show up a lot of them are irrelevant to the puzzle. You might have a pinned piece in your game which is entirely irrelevant to the theme of the puzzle, which might be mate in 1 with another piece. I'm not sure whether the themes are supposed to be like this, just name every concept you see on the board, or whether they're supposed to be relevant to the puzzle itself. Rather than just giving thumbs up and thumbs down based on how I believe the themes should be handled I thought I'd make a thread here to ask for advice. Should I thumbs down irrelevant themes? Or are the themes just supposed to list as many concepts as can be seen on the board?
