On the river there are no more cards to come, so a bet has exactly two jobs: get called by worse, or make better fold. A value bet is one where, when villain calls, you win more than half the time. That is the whole test — not 'is my hand strong' but 'of the hands that call, do I beat most of them?'. Top pair with a good kicker on a dry runout usually passes: villain's calling range is weaker pairs and ace-high that refuses to fold. Middle pair usually fails: the hands that call have it beaten, and the hands it beats fold.
Example. On K♦9♠6♣3♥2♦ you hold K♥Q♣ and villain checks (pot 20). Nothing completed; his check-check-check line is full of 9x, 6x, pocket pairs below the king and stubborn ace-high. Those hands call a bet and lose to you far more than 50% of the time: bet for value. On A♥9♦6♣4♠2♥ with 9♠8♠ (middle pair), turn it around: any ace, two pair or better calls and beats you, while 8x and worse folds. Your hand has showdown value but no value bet — check and see what villain shows.
Common mistake: betting medium hands 'for protection' on the river. There is nothing left to protect against; a river bet with a hand that only better hands call is a bluff you cannot win with.
Bluff selection
A river bluff is a bet with a hand that cannot win at showdown, chosen so that it folds out hands that beat it. Pick bluffs from your missed draws: they have zero showdown value (so checking wins nothing), and they block the straights and flushes villain would call with. Bluff only where your line makes sense — you bet flop and turn, the river completes nothing for the caller — and never into a player who has shown he does not fold.
Example. On K♠Q♦7♥3♣2♠ you hold J♦T♦, a missed straight draw with jack-high (pot 20). Checking wins exactly nothing. Betting 20 into 20 needs villain to fold 20/(20+20) = 50% of the time to break even, and his range after calling two streets is heavy with one-pair hands that hate a third barrel — bluff. On 8♥5♥2♣ K♦ 3♠ with Q♥J♥ the math is the same, but the read is not: villain is a calling station who never folds. Against a fold frequency near 0% every bluff loses the whole bet — check.
Common mistake: bluffing with hands that have showdown value. A pair of nines that might win at showdown should check; turning it into a bluff throws away the times villain checks back a worse hand.
Over-bluffing loses
Bluffs only make money because villain sometimes folds; how often he should fold is set by your bet size. When you bet the pot, villain is laid 2:1 and needs to be right just 33% of the time, so an unexploitable betting range holds about two value hands for every bluff. Bluff more often than that, and calling every bluff-catcher becomes automatically profitable for him — you are handing chips to anyone who simply refuses to fold a pair.
Example. Flip the seats. On Q♦9♥5♣4♠2♦ villain bets 20 into 20 and you hold Q♥J♣, top pair, facing a polarized range of strong hands and missed draws (pot odds 20/(20+20+20) = 33%). MDF = 1 − 20/40 = 50%, and top pair is comfortably inside the top half of your range: call. If villain bluffs even a little more than one-third of the time, this call wins outright. Now the other side: on K♦Q♣8♥5♠2♦ with J♥T♥ (jack-high) facing 16 into 20, you need 31% and beat nothing that bets — fold. Being a bluff-catcher requires actually beating the bluffs.
Common mistake: counting fold equity that isn't there. Against a range that is mostly strong, or a player who calls too much, every extra bluff is a bet you lose at full price.
Key takeaways
• Top pair or better, dry runout, villain checks → value bet; size to what worse hands will call.
• Middle pair or ace-high with showdown value → check; it beats only hands that fold.
• Missed draw with no showdown value and a credible line → bluff, pot-sized; it needs 50% folds.
• Missed draw vs a calling station → check; with fold equity near 0% every bluff loses.
• Facing a pot bet with a bluff-catcher → call the top half of your range (MDF 50%, you need 33%); fold hands that beat no bluffs.

FAQ
How do you size a river value bet?
Size to the worse hands that will call. Thin value wants a smaller bet that gets called by more marginal hands; a strong, polarized range can bet big or overbet.
How many bluffs should you have on the river?
Balance bluffs to value by bet size: a pot-sized bet mixes roughly one bluff for every two value hands, and bigger bets need fewer bluffs. Pick bluffs that block the opponent’s calls.
