After-play study. A face-up replay about runouts. Opponent cards are shown for explanation, not treated as information available during ordinary betting. All cards and action are fictional, not a personal hand or a solver recommendation.
The draw arrives. The hand is not over.
A completed draw is an obvious turning point in a poker video. It can also hide the next question: what can still change? Follow the hand one street at a time, then count every possible river from the turn snapshot.
The cast / Both hands shown
Player A
Player B
Start on the flop. Do not reveal the turn until you can describe both hands.
01 / Read the flop
B has three nines. A has four hearts across the hole cards and board, not a completed flush. B is ahead now. That is different from being guaranteed to win.
Before revealing: name a kind of turn card that could put A ahead. Keep a description of the current hand separate from a probability of eventually winning.
Reveal the turn
The turn is the four of hearts.
A now has an ace-high flush: ace, jack, nine, seven and four of hearts. B still has three nines. A has moved ahead, but one river remains.
For the next exercise, suppose all betting is complete and both hands are tabled. The remaining river is guaranteed without another payment. Do not use this face-up calculation to justify an earlier call against an unknown range.
02 / Count the ways back
Continue after opening the turn. Both hands are exposed and one river remains. Which exact ranks could let B beat the flush? Count physical cards, not just rank names.
Reveal the remaining-card count
There are 44 possible river cards: 52 minus four hole cards and four board cards. B wins on 10 of them, A wins on 34, and there are no ties.
| River rank | Cards left | B's best hand |
|---|---|---|
| Nine | 1 | Four nines |
| Seven | 3 | Nines full of sevens |
| Two | 3 | Nines full of twos |
| Four | 3 | Nines full of fours |
The ten physical cards are:
B's exact chance is 10 / 44 = 22.7%, rounded. A's is 34 / 44 = 77.3%. These are conditional showdown probabilities for the known hands, not measured opponent tendencies or a tournament-prize calculation.
Why not divide by 46? In a hero-only turn view, six cards are known. Here the opponent's two cards are also exposed, so eight cards are known. The information set determines the denominator. The calculation assumes a fair remaining deck and no other known dead cards.
03 / Deal the last card
Before opening the river, say what the best hand is now and what type of hand could overtake it. Neither statement needs the eventual result.
Reveal the river and showdown
The river is the two of diamonds.
A still has an ace-high flush. B now makes a full house: nine of clubs, nine of diamonds, nine of hearts, two of clubs and two of diamonds. B wins.
A did not lose because the flush became a weaker flush. A lost because B made a higher-ranked type of hand. An improvement on the turn is not a promise about the river.
Check a different river: what about another heart?
The two of hearts also makes B a full house. It is one of the ten losing rivers for A, even though it puts another heart on the board. Count what the card does to both hands, not merely which suit appears.
A rule such as “another heart is good for the flush” is not enough. On this exact turn, A already has a flush. Pairing the board can change the winner. The rank of a card and its suit can carry different consequences.
04 / Change one input
Return to the turn with the four of hearts on the board. Keep A's cards fixed, but change B's hand to the nine of clubs and seven of clubs. How many rivers now beat A's flush?
Reveal the changed-hand answer
With B holding nine of clubs and seven of clubs on the same turn, B has two pair rather than a set. The remaining two nines and two sevens make a full house. That is 4 / 44 = 9.1%, rounded. The other 40 rivers leave A ahead, with no ties.
A two or four now only creates a lower paired board for B; it does not supply a full house. The slogan “the board might pair” was too broad. Changing the opponent's hand changed which paired-board rivers actually matter.
05 / Explain the swing without rewriting it
A useful fictional voiceover is: “The heart moved A ahead. With both hands exposed, ten of the forty-four possible rivers would still beat the flush. This river was one of them.” It explains the changing situation without calling the result inevitable or impossible.
For your own review, save three items: cards known at the decision, cards that change the winner, and whether another bet must be paid before seeing them. A correct runout count does not by itself establish whether an earlier bet or call was good.
Draws and future payments explains that last distinction. The board-reading guide gives a broader vocabulary for what can change.
