Whites pawns all move 1 square simultaneously

A second queen on f1

dxc8

3g and 3f pawn promote to kings (hydra effect)

Black summons a whole row of pawns on the 6th rank

Kxd7 (i mean the 3g king)

Every single piece on the board shifts up (pawn, knight, bishop, rook, queen) in value. Queens "wrap around" to pawns, kings remain the same.

Every empty square is filled with a pawn.

ranks 1-4 white pawns and ranks 5/8 black pawns.

(After applying TNITLOL's suggestion.)

Someone else do all that. I give up

The white king that just moved explodes capturing all adjacent pieces

H8 pawn promotes to king

This took on a life of its own lol I'll just watch from the sidelines

Black strikes back by promoting his knights into queens

Ngl it's as fun as the original
