Odd case of Elemental in Korea and US

In The Rise Of Skywalker (2019) the Sith Fleet apparently doesn't know which direction to move their ships in in the climactic end battle. This is a metaphor for how Rian Johnson and J.J. Abrams didn't have any idea on which direction they should take this entire trilogy in.

Small village in Poland

nifty mate in three I found, white to play

reminder: if you're stalled for a while or even in a rut, it's okay to take a break. mental resets can be a good thing.

I am very proud of this move

What about it?

I want to get out of check while also putting pressure on the knight. I know I can just move one over and do the same but I also wanted to start playing with my rook, for what reason am I not allowed to castle here?

What should I do to regain that much elo loss?
