Why
Q♣9♦5♠ is a two-broadway-ish dynamic flop where the in-position BTN c‑bets a wide range; the CO is out of position. Your A♣5♣ has flopped bottom pair (a pair of fives) plus a backdoor club flush draw (A♣ with the Q♣) and an ace-overcard. The given raise is a check‑raise semi-bluff: from OOP you check, and against the BTN's c‑bet you raise, using your pair-plus-backdoor equity and the A blocker to fold out the BTN's overcards and floats while retaining outs (trips, two pair, runner clubs) when called.
Key idea
Bottom pair plus a backdoor draw and an overcard makes a fine OOP check‑raise semi-bluff: it folds out equity now and still has outs when called.
Common mistake
Justifying the raise with preflop '3‑bet bluff' logic instead of the real reason: a flopped pair plus backdoor equity check‑raised from OOP.
