* Tie-break winner (where known)
** In 1993 this event was advertised as the B.C. Open (and later lists refer to Piasetski as the B.C. Open Champion), but reports on the event in Counterplay and En Passant called it the Vancouver Open. In 1994 the event was only referred to as the Vancouver Open, but because of the previous year (and to maintain continuity) I have designated the 1994 event a B.C. Open.
