What an incredible thread with a wealth of information!!! Thank you all so much!!
I did an experiment: puzzles for 4 hours a day for 4 weeks.
George goodnight. Yes you will be doing twice as many tactics on the next cycle while having half the time. You actually spend less time each cycle because you have less time to solve.
why even try? you will never be good at this game. hard to face the truth sometimes
Please identify to whom you are speaking. If it is me, you can bite me. If it is someone else, you can bite me anyway. Just kidding/not kidding.
I started trying to go over a certain tactics book repeatedly, just as a test, but I got sick of it to be honest. Especially when it started getting to like 100+ problems in a day. Way too much. It may have helped some, but I couldn't notice a rating difference.
In contrast I had a year where I gained ~200 points and I was doing 10 tactics every morning. That seemed to help a lot.
1001 endgame exercises for beginners has some great trapable pieces exercises. There are quite a few that i just didn't see initially.
Just seen that lichess has trappable pieces section in their puzzles: https://lichess.org/training/trappedPiece
