--- Found Rabbi's Rule (4!S) — curated hands where the safety play applies

These hands are extracted from Rabbis_Rule.pbn by [find_rabbis_rule_makers.py]:
contract = 4!S, declarer = South, result >= 10 tricks (declarer made the
contract). Each hand demonstrates Rabbi's Rule —

  "When the King is singleton, play the Ace."

West holds the singleton !D K. East holds the !H KQ threat. To make
4!S, declarer must drop West's bare K rather than finesse for it.

Things to think about:
• Count your tricks before touching the trump suit.
• If you have 10 top tricks on the safety play, take them — don't
  finesse for an 11th and risk going down.
• The safety play here is dropping the singleton King.
