Best play: Bet 40% pot
Why
Turn (Q♣ 8♦ 4♠ | 2♠). Hero holds J♦ 9♦ with no pair — just Jack-high with a gutshot to the Ten (T completes Q‑J‑T‑9‑8) plus a backdoor diamond. Against the capped, check-first BB a small 40% bet works as a merged semi-bluff: it folds out the BB's weakest air, denies equity, and sets up a cheap stab while keeping the overbet reserved for the polar nut/air pairs. With no made hand and only a gutshot, a small size is the right pressure, not a 120% overbet.
Key idea
Jack-high with a gutshot on the turn prefers a small merged stab to deny equity, not a polar overbet reserved for nutted or pure-bluff holdings.
Common mistake
Overbetting a pure gutshot Jack-high as a polar bluff when a small bet denies the same equity far cheaper and keeps the overbet range credible.
