Why
On T♠7♠2♣ the 4♦ turn is a blank, leaving you with just king-high (K♦9♦, no pair, no real draw — the 9 is your only relevant overcard outs source). With the action checked to you in this heads-up single-raised pot, checking back is correct: you have no value to bet and turning king-high into a bluff is unnecessary when you can realize its modest showdown equity for free and still pick off the BB's busted bluffs on the river. Betting only folds out the worse hands you beat and gets called or raised by everything that beats you.
Key idea
With king-high and no draw on a checked turn, check back to keep your bluff‑catchers alive and realize free showdown equity.
Common mistake
Stabbing with king-high air, which only folds out worse and gets check‑raised, burning a hand that has free showdown value.
