I don't cheat on your website.
I have been trying your problems and I get these 25 ply or more chess problems on the 60,000 tactical problem numbers (on 3 different problems).
I am not a master, but they are way too hard for me.
Let's aim for 10 to 16 ply for the intermediate amateur player.
PS On a different "side" note, without the tiny solution arrows on the previous post, I would never have used this website in the first place.
