In this position, you have several board closing options. While SEV/JOGS j8 (26) looks appealing, ELOS is not that strong of a leave, and the board is still somewhat open for your opponent to play. VOE keeps a stronger leave, makes it difficult for your opponent to open the board or score, and making your 2 S even more valuable. On closed boards, the hook-ability of the S can prove to be very valuable.
