STANDARD. From 3 small lead Middle-Up-Down against suit contracts
and the top card against Notrump. Against Notrump the lead of
"Fourth from Longest and Strongest" is not always adhered to,
the defense choosing a "nothing" suit to remain passive.

ability to ruff losers. Signaling is also STANDARD.
