Why
Turn, board Q-club 8-diamond 4-spade 2-spade. With J-diamond 9-diamond you have only jack-high — no pair on this Q‑8‑4‑2 board — plus a backdoor gutshot (a ten would complete Q‑J‑T‑9‑8). The capped BB still has live equity here. With no made hand and no strong blocker to the queens, checking is the right line: it controls the pot, keeps your range protected on a board where you have little to bet for value, and lets you realize equity with your gutshot rather than bloating the pot with air.
Key idea
On a turn where you hold only high card plus a gutshot, checking back to realize equity beats turning a weak holding into a bluff with no useful blockers.
Common mistake
Betting jack-high as a bluff without blockers and getting raised off your gutshot equity, or auto-firing every in-position turn.
