`C` is all cards.
`p` is the part of playing cards.
`C_1` is all cards after play `p`.
求：
`P_a(C) = P_”activeWin”`
`P_p(C) = P_”passiveWin”`
设：
`P_d(p) = P_”dominate”`
`P_”f”(p) = P_”follow”`
`P_a(C) = max(P_a(p in C))`
`P_p(C) = max(P_p(p in C))`
`P_a(p,C) = P_d(p) * P_a(C_1) + (1-P_d(p)) * P_p(C_1)`
`P_p(p,C) = P_”f”(p) * P_a(p, C)`
