Why
Final board K♦ 8♠ 4♥ 3♦ A♣: the river ace gives BB a second top card, so their value is A-x and K-x while missed gutshots and busted 6‑7/diamond combos are the air. Your 9♠ 9♦ is now an underpair to both the A and the K — it beats only busted bluffs and the odd small pair, and loses to every A-x and K-x that BB would call with. Checking is correct: 99 is too weak to value-bet (only worse air folds, better pairs call) and has no blocker reason to bluff, so you take the cheap showdown and win versus the missed draws.
Key idea
Bluff‑catch: an underpair with showdown value checks back to win versus air rather than bet itself into better.
Common mistake
Value-betting an underpair to the board's two top cards — it only beats hands that fold anyway.
