Thanks, Peter. It finds and defends against these wins much better now. The macro I used, wtih comments: (define King-forward ( $1 (verify not-friend?) (if (in-zone? promotion-zone) (verify not-attacked?) ; to prevent moving into check (if (in-zone? promotion-zone a1) (capture White-throne) ; dummy position with a white King else (capture Black-throne) ; dummy position with a Black King ) add else (add-create) ; another macro to make the move and create a piece ; if appropriate. Your normal move goes here. ) ))
