How do they have 2 queens?

I think it's not crazyhouse, then how did white be able to kill black's queen when there is ne queen on the starting position.

the queen is promoted
wait more likely:
white promotes a queen, takes one of blacks pawns and places it
case closed?

It wouldn’t be crazyhouse since you’d need to capture their queen first. It could be bughouse though.

Yes, that’s possible too.
I'm black they're white. I know if you get a Pawn across you can get another piece. That could be how they got a queen, but two queens?
