Best play: Raise
Why
On Q‑9‑5 rainbow the BB c‑bets and you (CO) are OUT OF POSITION, since the BTN acts after you. Your 9 spades 8 spades is middle pair (the 9), with a backdoor spade draw and a backdoor gutshot to the straight. Check-raising here turns your middle pair into a semi-bluff that pressures the BTN's overcards and weak Q-x while you still hold real equity and a card that can improve to two pair or trips.
Key idea
OOP, a middle pair with backdoor equity is a fine check‑raise candidate against a c‑bet, not a passive call only.
Common mistake
Treating this as a preflop suited-connector spot and raising 'for implied odds' instead of reading the flop: it is a middle-pair semi-bluff check‑raise.
