Best play: Call
Why
Pair of kings with the K♣ blocker (it removes some of villain's value combos and holds no diamond, so the missed diamond draws stay in villain's range) is a top bluffcatcher, and MDF requires the BB to call enough versus this overbet-polarized jam.
Key idea
Against a polarized river overbet you only need to defend a fraction of your range, so call with top-of-bluffcatcher hands that hold relevant blockers.
