I have been playing atomic chess on lichess for some time but I still can't definitively state what pawns captures will look like. I think they have a kill radius of 1 but it doesn't effect other pawns? If anyone has a clear and decisive answer, I would love to hear it!
The captures in atomic chess work as follows:
- The captured and capturing piece always die.
- Then, anything around the capture square that's not a pawn dies.
For en passant, the capture square is the "bypassed" square of the double pawn move.
