Probe, delay & runout plans

A flop check is not empty time; it changes the next node. A probe is an out-of-position turn bet after the preflop aggressor checks back. A delayed c-betis the preflop aggressor betting the turn after checking the flop. Both lines begin with the same question: which strong and weak hands survived the flop check?

  1. Audit the check.List strong hands likely to bet flop and strong hands intentionally retained.
  2. Classify the turn.Ask which range gains nuts, equity, or useful blockers from the new card.
  3. Pick a target.Thin value targets worse calls; bluffs target better folds; checks preserve realization.
  4. Write the river branch.Before betting, name barrel cards, give-up cards, and value runouts.

Worked example: the check-back is evidence

Button opens, big blind calls. Flop K♠7♦2♣ checks through; turn 6♥. The button often bets many strong kings on this dry flop, so the check-back may be lighter at the top—but it can retain traps and medium kings. The six improves some big-blind pairs and straight draws. A probe range can bet two pair and sets for value, add draws that can barrel useful rivers, and check medium showdown hands. With 8♦5♦, the turn bet has a clear river plan: barrel a nine or four for value, consider only preselected pressure cards after rebuilding the caller's turn range, and give up on many paired rivers. “They checked, so bet” is not a plan; range shift plus runout map is.
