Why i will never be good at chess and many people too

Yes hacker I see, mine has no big red circle. I've reported you to chess.com shame on you. If cheap buy stop hacking. Bad bad person

i honestly cant say i have looked at all puzzle alternatives, but chesstempo's are very high depth puzzles with multiple trees to calculate and solutions are rarely intuitive moves .

most of my improvement from 1800 to 2200 was from chesstempo puzzles. Yes, they were lots of game analysis too but the tactics improvement was mostly puzzles from there. They refine your capacity to calculate and also just as importantly to evaluate a position accurately at the end of calculation (plenty of incorrect solutions, involve finding lines which are still +1 advantage but realizing thats not good enough and search for an alternative)

So far I took you seriously, but that's obviously going nowhere. With this posting you made it very clear that you're only trolling.

I don't get it, why do people enter discussions only to destroy them? It doesn't make sense to me. But I still stick to my principle assuming the best or give them the benefit of the doubt until proven otherwise. 

That's how tactics are for everyone... at first they're basically impossible. When you don't know the pattern all you can do is calculate a lot and hope you discover the solution.

After you learn the pattern (seeing it a few more times in games or puzzles) then you get be a lot faster, maybe like that 3-4 minute person.

Then later after it's part of your subconscious (however you want to say it) you can solve it very quickly.

Note that people who solve long puzzles in under 10 seconds are just guessing moves that look like something a puzzle would have... it's still heavy use of pattern recognition, but it's not as if they knew these moves would work for sure.

Incidentally, because puzzles with patterns you don't know take so long, it's better if you set a time limit. Don't just calculate for 15 minutes. If you haven't solved it after 10 minutes or so, then give up, and spend that time studying the solution.

Of course you can spend a long time if you want... just be aware you're training calculation more than tactics at that point.

Maybe i am very bad at chess and cannot see patterns but sometimes i just don't see it.

Especially in endgame positions i need to calculate all variations to see the whole picture. An obvious first move can be deceptive and if you rely on your intuition you can easily make a mistake. Why do i need to study a solution if can find it by myself?

Hope to discover a solution? There is no such thing. You either found it or not.
But maybe i overthink. The puzzle i am talking about has 37% rate. Maybe the whole concept is wrong because maybe many took wild guess and tried to pass it without solving all variations. That is why it has only 24 seconds target time which is insane to me.

Yeah, some people guess for sure.

I've seen low rated puzzles with very complicated defenses that they puzzle doesn't force you to find. You play the first two moves and it says you're correct and it's over... there's no way some of the people who solve certain puzzles have seen all the relevant variations... not unless they spend at least a few minutes.
