Tony has a threat on his king yes, but the threaterer has a threat on his angel so he cant threat the threatenee
Fast infinite sandbox game #1 (sign ups open)

It was probably a decision between losing his rook, or losing his dragon.
If that's the case Tony I promise not to take your dragon if you save you rook instead of capturing my rook.

I will just point out that I have been applying the rule that if you don't move out of trouble once every two moves you are capturable. Given that this has been the rule applied (well I've tried to) it will remain the rule. Not sure if it lines up with Nav's NEISG rules but I feel like it makes it's own sense.

Events:
until end of the game "Toroidal Universe" The board basically becomes a huge torus (or sphere), not infinite, but can expand infinitely to account for anyone's huge moves. If you make a huge move you can either decide for the torus to expand to fit your move, or you can choose for it to not and you just continue to slide and wrap around the board until you appear on the other side on the same rank/file/diagonal!
Turn 30-43 "Tanks" Pieces are not forced to stop moving upon capturing another piece, they can now continue to slide/keep moving along the same path after the capture. They cannot capture 2 pieces in 1 move.
Pieces that can be captured (with no risk of dodging) have the black triangles in the corners. Piece movements are now visible if off the board. Pieces that have just been dropped have a shape around them too.
Given the toroidal universe this cannot be 100% ensured. It's up to each player to think of the consequences of this event and if I don't put a capturable sign when there should be one do mention it when capturing it. I will not be trying to see what captures are possible.
Eh my king doesn't matter at this point in time
