You're the big stack in the big blind. A short stack open-jams about 5 BB and it folds to you with K♦9♦.

Big stack in the BB; a short stack jams ~5 BB to you with K♦9♦. Best?

WhyFive big blinds is pocket change next to your stack, and a short stack open-jamming does it with a wide, desperate range, so K-9 suited sits comfortably ahead of the equity you need to call. You also can't fold him out, so there's no bluff to fear - this is a pure price-and-equity decision. Covering a short stack cheaply is exactly why you call wider than usual.
What happensYou call and flip over a live hand against his range. Whether this particular one holds or not, calling wide against a short jam is the profitable habit for a big stack - so don't let a single bad beat talk you out of it.
Your big stack let you defend loose by design: against a short stack's wide jam the price was tiny and modest equity was all you needed, so K-9 suited was an easy call.

When a short stack jams and you cover him easily, your calling range widens - the price is a sliver of your stack and his shoving range is stuffed with hands you're doing fine against.
