Why
Q♥9♣4♦ is a moderately dynamic, two-broadway-and-a-blank board where the CO preflop raiser keeps a range edge but the BB has plenty of pair and draw interaction. Your J♠8♠ has no pair but a gutshot to the ten (T completes Q‑J‑T‑9‑8) plus a backdoor spade draw. A small range bet leverages your overall range advantage cheaply, denies equity to the BB's overcards and gutshots, and lets your weak draw apply pressure at a low price.
Key idea
On dynamic boards you still favor, use a small range bet with weak gutshot-plus-backdoor hands to deny equity cheaply.
Common mistake
Betting big with a bare gutshot bloats the pot out of position-control and gets called by the many pairs this board gives the BB, wasting your low-equity hand.
