Flop Analysis
Flop A94 rainbow with SPR ~0.6: we have a weak bluff candidate and some backdoor potential. Solver mixes between a small c-bet and check; checking is fine and keeps our range protected on a board that still favors BB’s range.
With ~9BB on the button, Q5s is a bit too loose as a raise; once we see A-high, turn Q gives us second pair and we should call the tiny turn bet and river bluff-catch.

Turn Qh gives us second pair on a board that still favors BB’s range. Facing a tiny 1BB stab into 9.5BB, we’re getting ~9.5:1 and need only ~10% equity, so calling is mandatory with a hand that has decent showdown value and some redraws.
River 2s doesn’t change much; BB’s 4BB bet into 14.5BB gives us ~3.6:1 and we need ~22% equity. Our hand is a bluff-catcher with a missed spade draw and we block some of BB’s missed spade draws, so calling is standard.
