The rules of sanctuary and re-takes make the pawns particu-

early vulnerable to attack. Here,​ the pawn on e7 is un-protected. Assuming it's black's move, it can respond by moving the e7 pawn for-ward one square--using a piece to block the Queen. Or, assuming the black Spy is in

Court, it can move him out of Court, thus triggering move-ment of the Queen or bishop onto c10 or h10, respec- tively.
