Some puzzles I played on this or any other puzzle website are unpractical. But most puzzles have been extremely useful. Rarely plays a HUMAN player plays the exact same COMPUTER GENERATED sequence that only puzzle suggests. This is true, especially under time pressure when you can't think of a 5 move sequence in 10 seconds (unless it's a forced mate or something like that).
A lot of times, there is a lot of options. Limiting the whole thing to ONE sequence is obivously only for the sake of the puzzle being a puzzle.
How I learn from puzzles I completly don't understand how something could be the best move is to analyze (with the magnifier symbol) the puzzle and try to logically understand the puzzle because I know it comes from a computer calculated logic and not a human logic.
We are obivously humans and can't calculate hundreds of thousand variables. I would suggest to always take puzzles with a grain of salt.
The puzzles on this site are garbage. End of story. Stick to other websites that actually have good puzzles pulled from real games and dont punish you for taking more than 15 seconds to solve, nor give you trick 400 rated puzzles when you think it must be more difficult because youre 1300.
The person who came up with this puzzle system should be fired immediately
Most of the puzzles come from real games, and most of them from games played on site.
I have run across very few problematic puzzles in 10 years and have probably completed 30,000+ puzzles in that time (I've reset at least 5 times).
