Definition
The river is the final street where all the cards are out. River betting is purely polarized—you're either betting for value or as a bluff. No more drawing.
River = No more cards, only value or bluff
River is Different
| Earlier Streets | River |
|---|---|
| Draws have equity | Draws are dead |
| Protection matters | No protection needed |
| Merged ranges work | Polarized only |
| Medium hands bet sometimes | Medium hands check |
River Value Betting
When to Value Bet
| Condition | Example |
|---|---|
| You beat villain's calling range | Top pair vs middle pairs |
| Worse hands will call | Villain is a calling station |
| You're ahead more than 50% | Math says bet |
Sizing for Value
| Size | Goal |
|---|---|
| 50-66% pot | Standard thin value |
| 66-100% pot | Thick value |
| Overbet | Nutted hands vs calling stations |
Thin Value Example
You: A♠ J♥ Board: A♦ T♣ 5♠ 8♥ 2♣
You have top pair, medium kicker.
Villain's calling range: A-9, A-8, T-T, weaker aces
You beat most of this. ✅ Value bet 50-60% pot.
River Bluffing
When to Bluff
| Condition | Example |
|---|---|
| Better hands can fold | Villain has capped range |
| You have blockers | Block their value hands |
| Story makes sense | Your line is credible |
| Villain is capable of folding | Not a calling station |
Sizing for Bluffs
| Size | Fold Equity Needed |
|---|---|
| 50% pot | 33% folds |
| 75% pot | 43% folds |
| 100% pot | 50% folds |
River Bluff Example
You: 7♥ 6♥ (missed flush draw) Board: A♥ K♣ 9♥ 3♠ 2♦
You have nothing. But you can rep:
- Flush that bricked (if villain doesn't have it)
- A-x that improved
If villain has marginal pairs, bet 75% pot.
River Checking
When to Check
| Your Hand | Why Check |
|---|---|
| Medium pairs | Showdown value |
| Weak made hands | Beat some bluffs |
| Hands that lose to calls | Don't bet into strength |
| Induce spots | Let villain bluff |
Value-to-Bluff Ratios on River
| Bet Size | Optimal V:B Ratio |
|---|---|
| 50% pot | 2:1 (67% value) |
| 75% pot | 1.5:1 (60% value) |
| 100% pot | 1:1 (50% value) |
River Mistakes
| Mistake | Problem |
|---|---|
| Betting medium hands | Turn value into bluff |
| Missing thin value | Checking back winners |
| Over-bluffing | Caught too often |
| Bluffing calling stations | They don't fold |
Key Takeaway
River betting is binary: value or bluff. Bet for value when worse hands call. Bluff when better hands fold. Check medium hands with showdown value. Size based on what you're trying to accomplish.
