What are your predictions for the Game 4 starting pitchers?

For Game 3, it looks like Choi Won-tae and Shirakawa are pretty much confirmed.
I'm not sure about Game 4, though.
First, for Samsung.
It feels like Won Tae-in needs to pitch, but if he's staying in a relief role, he might be excluded. FedEx (Fedec) hasn't had much rest. For reference, he threw 94 pitches in Game 1. If he has the will, FedEx is possible. Since it's only a 3-day rest, given the unique nature of the postseason, it doesn't seem impossible.
There's also the possibility of a bullpen day, starting with Won Tae-in pitching a short outing followed by Yang Chang-seop and Jang Chan-hee. Anything seems possible.
Next, Kia.
They have more breathing room regarding their starting pitchers.
First, there's Yang Hyeon-jong. Then there's Nail, who came out after throwing 57 pitches in Game 1. If Kia manages to win Game 3 with Shirakawa, I could see them going for a shutout in Game 4 with a Yang + Nail combination.
Or, in true postseason fashion, they might boldly start Nail.
