76s on A♣ 7♦ 3♠ facing a check-raise — fold, call or raise?
The answer
Call
pay $30, bluff-catch
Solvers also mix: Fold
The math: call $30 to win $70 → need 30% · the dry rainbow board supplies few natural semi-bluffs, so second pair is near the bottom of a continuing range.
Why
A♣7♦3♠ is dry: there is no flush draw and only a few straight backdoors, so the Big Blind has fewer natural semi-bluffs than on a wet ace-high flop. That means you should call less readily, but it does not make every raise value. At this price the audited wide-range solve still calls second pair, so call is the displayed line; folding is accepted against a value-heavy population. The board alone never justifies claiming that bluffs outnumber value.

Why not: Raising turns a bluff-catcher into a bluff. It folds out the air you already beat and gets called only by the ace-x top pairs and sets that have you crushed. Second pair is far too thin to raise for value.
The idea behind it
Bluff-catching frequency starts with range composition. Wet boards create obvious semi-bluffs; dry boards require more pure bluffs, so marginal pairs call less often. Price, positions and full ranges still matter, and can leave call as the main line with fold as an opponent-dependent alternative.
Concept: Texture before bluff-catching
