I found this, it is a bughouse video the the chess.com YouTube channel made: https://www.youtube.com/watch?v=6FWRYRZmpDg
Is there any practical bughouse engine that exists at this point?

I found another video on chess.com based on a bughouse engine:
https://www.youtube.com/watch?v=dQw4w9WgXcQ
Is there any place that you can analyse your bughouse games? Any place you can see bughouse engines play against each other? I spent some time searching but couldn't find much meaningful results.
Also, there are no lessons regarding variants on chess.com lessons section and this club seems quite dead too. Can anyone recommend me some useful sites or youtube channels where you can see some analysis on decent gamed that has been played?
