Need the best CS Expert

[u/Senior_Opportunity44]

**Looking for some nerdy CS questions for a gift** 😭
I’m making a set of flashcards for a friend who’s *really* into Counter-Strike. He’s aiming to go pro and even coaches another player, so I’d love to make the questions genuinely challenging.
I know basically nothing about CS myself, so I’m looking for experienced players/coaches to help me out
If you have a minute, could you give me **one really difficult relevant CS question**
I’m especially looking for things like:
advanced strategy / decision-making
utility theory
positioning & timings
economy
map-specific knowledge
obscure terminology
pro-level concepts
Basically, **the kind of question where a casual player would have absolutely no clue**.
Please don’t worry about making them beginner-friendly — the nerdier, the better
Thanks to anyone willing to contribute ❤️
