I'm not familiar with the tactics trainer here, but if it doesn't allow you to specify a difficulty range, that would be pretty stupid.
Is there a way to change the difficulty level of the tactics problems I'm given?

In the Tactics Trainer settings, it says that premium members can turn off ratings and specify a rating range. So, I guess you can do that.

Correction - In the *V2* Tactics Trainer settings, it says that premium members can turn off ratings and specify a rating range. I couldn't see how to do that in V3. Maybe staff made a deprovement in this case?

Seems like you guys don´t have the natural intuition a successful software developer like me has.
You are very much welcome "Товарищ"

Problems are selected via your tactics rating. 1400 tactics are easy. 2200 does not seem to crazy when we take in consideration you are rated 1823 on tactics. There is only one way to the top and that is by solving harder puzzles.

ideachess.com tactics are way more friendly. Tactics should be enjoyable, not punishing.
2 points if you get it right and minus 14 if you get it half wrong. Bah.
I set it to 1500-1900. Anything under 1500 was stupid easy (first tried 1200), like a piece en prise and I just have to verify it is safe to take it, which it is. 1500-1700 looks like what I encounter in my games but that I might miss for not knowing it is there and being under time pressure. 1700-1900 is a bit challenging, but I still solve 80% in enough time to work in a game for a key move, since I'm told it is there. The 1900-2200 problems where taking 5+ minutes and with a 50% pass rate. They were educational, but I'll come back to them later.
These don't affect my rating, but whatever. Practice is practice.
As for finding the adjustment, I would have clicked the icon had I noticed it before. I really wonder why I did not notice it. This is worrisome, since I want to go into software. I wonder what I need to do to build the natural intuition.
I'm rated around 1400 but am frequently given problems rated around 2200. It takes a lot of time to solve them, and I only solve half. If I solve move, it just gives me harder ones.
I know I can go to a list of all the tactics problems and sort high to low and low to high, but there are hundreds of thousands, from 400 to 3400, which would take forever to get to 1400.
Maybe I just need to ask it for the answer after 20 seconds on 20 of them, and only put in full effort on 5. That would likely bring the difficulty level down.
