          Give one other card from your hand to another player with room, then
          discard Distrans. No spice is paid. The transfer happens immediately,

          Provisional bid timing: you may transfer before the first bid or pass
          on an ordinary auction lot. Once anyone bids or passes, that lot stays
          blocked while unresolved. Special auctions keep their existing
          restrictions.
