Blocked in game

I’m stuck in game 2567645 with a pawn that cannot play - whereas it should be able to move forward.

That pawn move is not currently legal. According to the rules of Grand Chess, a pawn can only be promoted to a piece that the player has already lost. But you still have all your pieces. Therefore, your pawn cannot advance any further because it cannot be promoted.

I wasn't aware of that rule… RTFM I guess… sorry! (weird rule by the way)
