You took on both tests and failed both.
Well, since you seem to enjoy a lot seeing me fail, here's a treat. From the
Start Your Engines Challenge, Week 3, Problem 4, the "anti-Ovyron" test:
[Event "Plaskett's Puzzle White to win"]
[Date "2018.02.20"]
[Round "4"]
[Result "1-0"]
[SetUp "1"]
[FEN "8/3P3k/n2K3p/2p3n1/1b4N1/2p1p1P1/8/3B4 w - -"]
1-0
[d]8/3P3k/n2K3p/2p3n1/1b4N1/2p1p1P1/8/3B4 w - -
Couldn't find the winning move to save my life (ironically, I'd have still played the winning move, by luck, but for the challenge it was required that I found the win, which I found impossible.) All my methodologies failed, hope you enjoy that
Frankly, I've never cared about failing or succeeding in these, I care about what's the truth, sometimes it can't be found alone. I'm more happy losing 1.g4 against Harvey than I'd be if I drew that but it turned out 1.g4 was lost (but Harvey failed to win it). It's more important to find the truth than to see who loses what.
I am surprised to read that you failed the Plaskett's puzzle that is an old puzzle because even a very old chess engine from 2004 can solve it

Even without engines you could solve it simply by searching with google for the fen and getting
https://en.wikipedia.org/wiki/Plaskett%27s_Puzzle
I could expect you to fail some new problem that somebody comosed when searching with google is not going to help you and not some old problem that many years ago people made engines to solve it.
