In the Alice Chess preset I'm testing, I have come to a position where a move I was thinking of is not being allowed by the preset. The Red King is in check, possibly checkmate, depending on the interpretation of the rules. It seems my code is in conflict about this. It is recognizing it as check rather than checkmate, but it is also not allowing any move that could end the check. I was thinking of moving the F6 Knight or the F8 Rook to G8, from whence it would move to g8, blocking the check. The problem with both of these moves is that they leave the King in check until the piece transfers to the other board. I have coded this to be illegal under the understanding that any move leaving the King in check before the transfer is not legal. This certainly makes sense when the piece and King are on the same board. But here they are on different boards. The rule "A move must be legal on the board where it is played" is ambiguous. A loose interpretation is that it refers to a piece's own powers of movement, and a strict interpretation is that it disallows any move that leaves the King in check before the transfer. How have people been interpreting the rule in situations like this?
