ATTENTION EDITORS: the applet wants to play the illegal move 17... e7-e5 in the game below, ignoring the White Rook on e6. I wonder if two-step initial pawn moves were coded as leaps here.
At first glance, the final position here (with a blockade stalemate) may appear impossible, but I managed find a legal sequence of moves leading up to it. Shatranj blockade stalemates are actually easier to construct. H. G. Muller has posted an applet in the Shatranj Comments (May 3, 2021). Click "Play it!" and copypaste the second game to see an example. Clicking "Move" at the end makes the applet appropriately respond with *** I resign! ***
