We have the brick for declining En Passant,( not sure why though cause it’s forced).

So, one of the Emus was playing a game recently. He had two pawns on an edge, let’s say a6 and a7. Kings on a8, and one of the opponents pieces is on b8.

So, I… The Emu has a flash of brilliance and decides promoting to a Queen isn’t what’s going to happen and instead chooses a War Tower.

Welp. King just moves into the empty space. Several moves later GG.

Should there be a penalty for incorrectly under promoting and it costs the game, and if so what should it be? Asking for a friend.
