Why
River: final board Q♣ 9♦ 6♣ 2♠ A♦. Hero K♣5♣ has only two clubs (Q♣ 6♣) on board, so just four clubs total — no flush — and no pair, leaving king-high with the river ace on top. King-high beats only worse air, so a 40% bet only gets called by better and folds out what it already beats. This should be a give-up check, not a thin value bet.
Key idea
Count the suit before claiming a flush: two of your suit on board plus two in hand is only four cards, not five. King-high with no showdown-improving holding belongs in the check/give-up bucket.
Common mistake
Miscounting Q♣ and 6♣ plus K♣5♣ as a flush — it is four clubs, not five. Betting king-high for thin value on the river only loses to everything that calls.
