I was watching a twitch stream earlier and I'm just trying to learn a bit from some of the stuff that people do (I'm still fairly new), so I asked the streamer why he played a certain move and his response was "Well it's just so obviously the best move".
Idk, it just seemed a little arrogant, I'd already sort of mentioned that I was relatively new to chess, my ELO is around 850 even on the site where you start at 800.
