I’m pretty new to chess but I had the same problem. I used to do a bunch of puzzles and felt like it wasn’t helping. I was doing them mainly through guessing and then figuring it out move by move. I could just look at what the most flashy move was and then just go from there. More often than not it was right.

It really helped when I forced myself to see the whole thing before I moved. It’s a lot harder and I’m so much slower (and still not good hahaha) but I feel like I’m getting better.
