Why
Final board K‑8‑4‑3‑A: villain's range is full of K-x and A-x value plus missed straight draws and busted broadways, and the river A pairs nobody for hero. Hero's 9♠9♦ is an underpair below BOTH the king and the ace — a weak showdown hand that beats only busted draws and holds no blocker to villain's value. In position with the river checked through, an overbet would be turning a hand WITH showdown value into a bluff that folds out worse air and gets called only by better; hero should simply check back and win against the missed draws.
Key idea
Don't bluff with a hand that already wins at showdown — turning made showdown value into a bluff only loses you the pot.
Common mistake
Overbetting a no-blocker underpair as a bluff when checking back wins against all the busted draws.
