Paradox Solution - Sublevel 1

Checking the source, you'll find 'e4 e5'. If you know chess notation, these are terms for moves in chess.
Alternatively, you could had just googled e4 e5.
Doing so will get you the Open Game opening. opengame.html

Part 2

When you open the page, you'll be greeted with a white page. Check the source (obviously)
'Let's look into the glitch' refers to the image in the sublevel.
'Exit true = false' means T -> F, and you get EXIF. Description will say 'Nf3 Nf6'
This is known as the Petrov's Defense. petrov.html

Part 3

Same thing as open game page, check source.
UNIversity, only the first 3 capital letters are important. UNI refers to Unicode (probably didn't make that too clear rip lol)
Convert to unicode and you get two delta symbols.
'This character can be a letter and a number' Delta can be the letter D and the number 4.
You'll need to know chess notation to be able to use this information (everyone knows it tbh)
Delta symbols -> d4
d4 initates the Steinitz variation. steinitz.html

Extra Notes

In testing, I accidentally thought this was the Scotch variation of the Petrov's defense. This got fixed
Part 3 was just considered 'the stopping point for 90% of people' so bad that I had to give some nudges
Someone pointed out part 2 hint came from FTB. I forgot FTB existed tbh lol

You should know how to access the other pages.
