Why
A♦8♣2♥ is a dry, ace-high board where the BTN preflop raiser holds a large range and nut advantage over the BB. K♦Q♦ is only king-high here (no pair), but it carries a backdoor diamond flush draw (one diamond on board) plus backdoor broadway equity. On such a static board you range-bet small (33%): the tiny size lets your whole range fire cheaply, denies the BB's two-overcard and weak-pair equity, and your backdoors give your air just enough to keep betting.
Key idea
On dry ace-high boards the IP preflop raiser range-bets small with almost the entire range, including air with backdoors.
Common mistake
Checking back king-high because it 'has no pair' surrenders the cheap range-bet and the fold equity this static ace board generates.
