Barreling & follow-through
A flop bet is rarely the whole plan. Barreling is betting again on the turn (and sometimes the river) when the reasons that justified the flop bet survive the next card. The name matters less than the discipline: each street is a fresh decision about the same two currencies.
Those currencies are the ones from Lesson 16 — equity you still hold when called, and fold equity the new card creates or destroys. A turn card that favors your range over the caller's (an overcard to their pairs, a card that completes little of what they chased) typically adds fold equity; a card that completes their draws typically removes it. Topic 8's texture lens applies street by street, not just on the flop.
The shrinking continue range
One pinned hand — button opens 2.5bb, big blind calls, then check-calls a half-pot bet on K♠7♦2♣ and another on the Q♥ turn. Each row shows how much of the preflop calling range is still standing, computed live by the same range-estimation walk the grader uses.
| Street | Action | Still continuing |
|---|---|---|
| Preflop | BB calls the 2.5bb open | 100% |
| Flop K♠7♦2♣ | BB check-calls a half-pot bet | 63% |
| Turn Q♥ | BB check-calls again | 38% |
Read the table from the bettor's seat: every call strips the weakest part of the range that faced the bet. The second barrel fires into a stronger range than the first — capped, because a check-call is not a raise, but tighter. That's why barrels typically need something new: improved equity, a genuinely scary card, or a read that the remaining range is still fold-heavy. "I bet the flop" is not, by itself, a reason.
Giving up is a play, not a failure. Checking back after a called flop bluff keeps the pot small, keeps your bluff-catchers cheap, and saves the barrel for turns that actually shift the ranges. The worst habit in the game is turning one optimistic flop bet into three mandatory ones.
When the aggressor doesn't follow through, the roles flip. A caller who checked a street and saw the aggressor check back typically leads many turns — a probe bet — because the check-back capped the aggressor's range (the grading page describes how a check caps a range). And the aggressor who checked back bets many turns unimproved — a delayed c-bet — for the same reason in reverse. Both plays live off the cap the missing bet created.
This app grades each bet or check on its own street against the live ranges — the walk in the table above is literally the model it grades you with. It does not reward or punish "momentum"; a barrel is judged by what the turn actually changed.
