What do you think about this?

  In this position, chess.com did not let me recapture the queen. The queen is defended by the rook through a jump spell, so it thinks that capturing the queen would put myself in check. However, the jump spell will expire at the start of my opponents next turn so the rook would not actually be able to take my king... I feel like this is a mistake by chess.com

Yeah...

That's weird

I have dealt with that before and it's definitely strange, but it's not something I'm too worried about needing to change. I think it makes for an interesting game mechanic. Of course, as it is he's handed you his queen on a silver platter. (Assuming you didn't time out. Flagging is rough.)

I've also ran into this but I like the mechanic. The game's logic is that the queen is *currently* protected by the rook and doesn't allow for the queen capture. Attackers have to remember that when they do a jump spell; one of the many little nuances of the game.

You could have probably frozen his rook and recaptured the queen

That would lose on the spot to freeze@e7 Nd5#. EDIT: Unless black played freeze@d2 to freeze both the rook and the knight.

I just reached 2300 / top 16 in spell chess and didn't know this was a thing.
I agree with the OP that not allowing the re-capture of the king is not in the spirit of how the spells work in other situations and probably should be changed. But good to know that this is how it works.

Rook looks like a pawn lol
