Why
Turn Q-diamond 9-club 4-spade 2-diamond and hero is the BB out of position versus the BTN. 9s8s is exactly second pair of Nines with an eight kicker and no flush, with only one backdoor spade left dead. Check-raising as part of a mix turns this medium-strength pair into protection plus fold equity against villain probes, denying overcards and the diamond runouts a cheap look while still having showdown value when called.
Key idea
A check‑raise mix with a medium pair adds protection and fold equity on dynamic turns out of position.
Common mistake
Treating second pair as a pure passive bluff‑catcher misses the protection a turn check‑raise provides on a wet board.
