Never Tell Me the Odds

Win a hand of pazaak with all nine of your table slots filled. You'll need a decent side deck (+/- cards) to steer your total to exactly 20 across nine cards without busting - keep playing number cards and nudge with side cards to fill the board and still land on 20 (or beat your opponent) before you'd otherwise stand. Buy side-deck cards from pazaak dealers first to make it doable.
