Why
On Q♣9♦5♠ the BTN's in-position range connects well, but as the CO out of position you hold J♣T♣: an open-ended straight draw (any 8 or K makes the straight) plus a backdoor club flush draw. With eight clean straight outs and extra backdoor equity, check-raising the BTN's c‑bet is a strong semi-bluff — you generate fold equity now and can barrel hard on the many turns that complete or improve you, which is exactly what an OOP player needs to avoid passively check-calling and missing.
Key idea
Out of position with a strong draw (open-ender plus backdoor), check-raising builds the pot and adds fold equity instead of letting the in-position player realize cheaply.
Common mistake
Just check-calling the open-ender, which surrenders fold equity and lets the in-position BTN control the price on later streets.
