The first pass should decide how many attacking options each side can use. Daejeon JKJ W has recently turned strong serving and a setter switch into points from several positions. Expressway Co W has also shown it can keep multiple scorers involved and finish close sets. The contest hinges on which team can carry its first-contact plan through the later sets.
JKJ's recent win over Hyundai showed the shape of its attack. Choi Seo-hyun took over at setter after the opening set, and strong serving unsettled Hyundai's reception. Zhong Hui remained productive while Shin Eun-ji and the middle attackers supplied points around her.
That serving meets a real test in Expressway's wing reception. Targeted serves troubled Mami in Expressway's loss to GS, but Expressway's later wins featured Moma as the closer, Mami as another wing option and Kim Se-bin through the middle and at the block. JKJ needs its central and right-side attacks to keep that block from settling on Zhong in tight rallies.
Bukilic missed JKJ's last verified match with a calf injury, and the Hyundai win was built without her. Yeum Hye-seon started that match before Choi took over; the coach described the switch as tactical. Expressway used Lee Yun-jung to feed its several scorers in its last match.
I expect JKJ to press Expressway's reception early, then use its setter options to keep the attack spread as sets tighten. Its recent service pressure and completed comeback give it a concrete path to sustain that pattern across the match. That's why I'm siding with Daejeon JKJ W to win.
