Ruffing Finesse

by Richard Pavlicek

A ruffing finesse is the lead of a significant side-suit card when the opposite hand is void, then ruffing or not depending on the whether LHO covers or plays low. When the ruffing finesse loses, it may still provide material gain with a loser-on-loser play, also covered here.
