When I set the Applet diagram to 8 files and 10 ranks and then added a row of Omega Pawns to each side on the rank in front of their K, and pressed Start Position (but without using the AI engine), the pawns could take initial triple steps (as indicated by the diagram prior to moving) when I played a few moves against myself. However, there was no indication by the diagram that a legal en passant capture was possible, even if an enemy pawn was now on the same rank (and on a file right beside) a triple-stepping pawn.
