Opponent’s options: AFF 4k, AFFINE 14a
Scoring options: QI 10g, IWI 4k
Setup potential: Yes

Although setup plays like prig/grip 14b can be blocked, the cost of blocking is too high, making them worthwhile. If they block, you can play IWI next turn with two Q spots. As such, your opponent has to cede you the QI spot, making this setup useful and effective.
