BvB 3-Bet Pot Deep Dive: 9♥ 5♦ 3♣ Rainbow at 100bb Cash

The blind-vs-blind 3-bet pot is one of the most complex and frequently misplayed spots in 100bb cash games. When the board comes 9♥ 5♦ 3♣ rainbow — one of the driest possible textures — both players face a deceptively nuanced decision tree that most regulars get wrong.

This deep dive breaks down every decision point from preflop through the river using solver-verified data. Whether you're the 3-bettor in position or the caller out of position, you'll walk away with a complete strategy for this board texture — and every board like it.

💡 WHAT YOU'LL LEARN

  • Why BB uses two c-bet sizes (80% and 25% pot) — and which hands go in each
  • Why sets never raise the big c-bet but raise the small one 64% of the time
  • The optimal delayed c-bet strategy when BB checks back the flop
  • A complete river framework using the 5-class hand classification system

Want to run this analysis on your own spots? Solver+ gives you access to precomputed GTO solutions for thousands of common spots, and Postflop+ lets you train these decisions against a GTO bot until they're automatic.

1 The Setup: Preflop Ranges

SB opens to 3bb. BB 3-bets to 9.6bb. SB calls. The pot is 19.2bb with 90.4bb behind for each player — an SPR of 4.71.

BB's 3-bet range is polar — premiums at the top, suited connectors and bluffs at the bottom. SB's calling range is condensed — hands too strong to fold but not strong enough to 4-bet (JJ+ and AK 4-bet).

SB (OOP Caller) — Condensed Range

SB's range is built for boards like this. With no JJ+ or AK (those 4-bet), the range is heavy on pocket pairs (22–TT), suited broadways (KQs–AQs), offsuit broadways (KQo–ATo), suited connectors (54s–T9s), and suited aces (A2s–A9s). It's a middle-heavy range that connects well with low-to-mid boards.

BB (IP 3-Bettor) — Polar Range

BB's range is wider (229 weight vs 196) and much more polar. It contains AA, KK, QQ, JJ at the top — hands SB cannot have — and a wide assortment of offsuit bluffs (A2o–A7o, K5o–K9o, T7o, J8o) at the bottom. Mid pairs like 77–TT are at 0.5 weight (mixing 3-bet vs call).

Range Asymmetry → Strategy Asymmetry: BB's polar range creates the two-sizing dynamic on the flop. The overpairs need a big bet for protection. The bluffs and thin value need a small bet. SB's condensed range means check-call is the dominant response — SB has equity with most hands but none are strong enough to lead.

What's NOT in each range

SB does NOT have:

  • JJ, QQ, KK, AA — these 4-bet
  • AKs, AKo — 4-bet at high frequency
  • Low offsuit trash — folds to 3-bet

BB does NOT have:

  • Very low hands (32o, 42o) — even BB has a floor
  • 77–TT at full weight — mixing 3-bet/call
  • QJo, KJo at full weight — some stay flat

2 Board Analysis: 9♥ 5♦ 3♣ Rainbow

9
5
3

This is one of the driest possible flop textures. No flush draws. Almost no straight draws (only 46 has an open-ender). The board is low, disconnected, and rainbow — a Type B board where the default strategy is "small bet or check."

Range–Board Interaction

SB smashes this board:

Sets (33, 55, 99), top pairs (A9s, K9s, Q9s), suited connectors with equity (76s, 87s, 65s, 54s), all pocket pairs 22–TT

BB partially connects:

Overpairs (AA–JJ that SB can't have), some 9x combos (K9o, Q9o, T9s), but also tons of complete air (A2o–A7o, K5o–K7o)

The Twist: On a Type B board, the default is small-or-check. But the solver reveals BB uses two sizes: 80% pot and 25% pot. Why? Vulnerable overpairs (QQ, JJ, TT) need the big sizing to deny equity from SB's 6-out overcard hands. This is the Type B exception — equity protection overrides the dry-board default.

3 Pot Geometry: Planning Across Streets

At SPR 4.71, how many streets of value can each hand type extract? The answer depends on which flop sizing BB chooses — and this choice shapes the entire hand tree.

Hand StrengthStreets for StacksSizing Plan
Sets, two pair3 streets comfortablyAny sizing — want all money in
AA, KK3 streets at ~60%/street25% flop → preserves 3-street plan
TT, JJ, QQ2 streets — must deny NOW80% flop → compress to turn + jam
Top pair (9x)1–2 streets maxBet/call flop, reassess turn
Draws (76s, A4s)Depends on oddsCheck-raise or call, re-evaluate

Pot Progression by Line

LinePot After FlopSPR → TurnPot After TurnSPR → River
BB bets 80%, SB calls4,9921.50~11,600~0.36 → jam
BB bets 25%, SB calls2,8802.97~5,760~1.24
BB checks back1,9204.71~2,880~2.97

4 BB's Flop Strategy: The Two-Sizing Dynamic

After SB checks (which happens 98.3% of the time — treat it as always), BB faces the most important decision of the hand: bet size selection.

Bet 80% pot — 33.2%
Bet 25% pot — 25.4%
Check — 41.4%

BB c-bets 58.6% of the time using two distinct sizes, and checks back 41.4%. This is not a range-bet spot. Each sizing serves a fundamentally different purpose.

Reserved for vulnerable overpairs and strong top pairs that need equity denial.

The big bet forces folds from SB's 6-out overcard hands and charges gutshots. After bet + call: pot = 4,992, SPR = 1.50 — a single turn barrel effectively commits both players.

HandBet 80%Bet 25%CheckWhy
TT98.8%0.9%0.2%Most vulnerable overpair. Bets huge to fold out SB's overcards.
JJ88.9%10.7%0.4%Same logic, slightly less vulnerable.
QQ71.6%26.9%1.4%Mixes — fewer overcards beat it, so small size captures value too.
K9o69.9%20.4%9.7%Top pair good kicker. Protection + value.
AKs44.2%38.4%17.5%Two overcards. Denying SB's second/third pair is very profitable.
JTo47.4%20.6%32.0%Gutshot + overcards. Semi-bluff.

Thin value, equity denial with non-vulnerable hands, and balanced bluffs.

Extracts value from SB's weak pairs and underpairs while risking less. After bet + call: pot = 2,880, SPR = 2.97 — room for full turn + river extraction.

HandBet 80%Bet 25%CheckWhy
AA27.8%43.6%28.6%Not vulnerable to overcards. Small bet keeps SB's range wide.
KK38.7%47.2%14.2%Same logic, slightly more vulnerable than AA.
990.2%69.0%30.8%Flopped set. No protection needed — keep villain in.
95s4.5%82.2%13.2%Two pair. Extract from SB's continuing range.
T9s6.5%53.0%40.5%Top pair decent kicker. Thin value.
AQs16.1%43.8%40.1%Overcards. Small bet denies equity at low cost.

Hands with showdown value that don't benefit from betting, or pure air that can't profitably bluff.

SPR stays at 4.71. These hands either realize equity for free or start a delayed c-bet plan on the turn.

HandBet 80%Bet 25%CheckWhy
ATs0.8%0.8%98.4%Overcards with showdown value. Nearly pure check.
KQs2.3%4.7%93.0%Strong overcards, no pair. Preserve equity realization.
AJs1.2%9.3%89.6%Too much SDV to waste as a bluff.
76s0.5%23.8%75.8%Gutshot (needs a 4) + two overcards to the 3. No pair — pure draw.
K8o5.9%18.0%76.1%Underpair to board. Check for showdown.
T3s0.5%12.8%86.7%Weak top pair. Pot control.

🔑 KEY INSIGHT: Overpair Vulnerability Drives the Big Size

TT bets big 98.8%. JJ bets big 88.9%. QQ bets big 71.6%. These hands have 2–4 overcards that can arrive on the turn and kill their equity. Meanwhile, the strongest hands (AA, KK, 99) prefer the small size or check — they are not vulnerable and want to keep SB's range wide. The big bet exists almost exclusively for vulnerable overpairs.

5 SB's Defensive Strategy

How SB responds depends entirely on which sizing BB chose. The check-raise frequency is 2.6× higher against the small bet — a critical structural feature that punishes indiscriminate range-betting.

SB Response Distribution:

Fold
44.8%
Call
46.9%
Raise
8.2%

Fold (44.8%): All offsuit overcards (KJo, QJo, KTo, ATo), weak suited hands (K8s, T8s, Q8s, A6s–A8s), bottom pairs (44, 22)

Call (46.9%): Sets (33, 55, 99 — slow-playing!), underpairs (66–88), top pair (T9s, J9s, 97s), suited connectors (76s, 65s, 54s), premium overcards (AQo, AJs, KQs)

Raise (8.2%): TT (89.7% raise!), A9s (96.8% raise), K9s (40.2% raise), semi-bluffs (AJs, JTs at ~15–23%)

Why sets DON'T raise the big bet: After BB bets 80%, the pot is already 4,992 chips. A check-raise would create a pot of ~8,064 with only ~4,432 remaining — effectively committing both players. Sets prefer to keep the pot smaller and extract on later streets. The big c-bet already built the pot; raising just folds out bluffs.

SB Response Distribution:

Fold
16.8%
Call
62.1%
Raise
21.1%

Fold (16.8%): Only the absolute worst — KJo (83%), QJo (82%), KQo (51%)

Call (62.1%): Almost everything — 88 (97%), 44 (96%), 22 (100%), 77 (83%), AQo (97%), all decent hands

Raise (21.1%): TT (84%), A9s (83%), 33 (64%), 76s (75%!), K9s (60%), A4s (50%), 99 (40%)

The small bet unlocks set-raising. Against the 25% bet, 33 raises 64% and 99 raises 40%. Against the big bet, both were pure calls. And 76s raises 75% as a semi-bluff — gutshot (needs a 4) with excellent equity and fold equity. Every time BB bets small, they face a 21% check-raise frequency.

When SB check-raises, the hand enters a high-variance path. The XR range and BB's response differ dramatically by which sizing SB raised against.

SB raises to ~2× (~3,072). Pot becomes ~8,064 with only ~4,432 behind — SPR 0.55. Both players are functionally committed.

7 Turn Strategy by Path

Pot ~49.92bb · Stacks ~75.04bb · SPR ~1.50

BB's range is polarized (overpairs + bluffs). SB's range is condensed and strong (sets, pairs, connectors). SB almost never donks — CHECK ≥78% on every card.

Turn Card Impact on BB's Strategy:

7, 6MinimalTwo pairs/straights for 76s/87sSize down slightly. SB improved more.

The Nut-Donation Principle: Every bet is a donation into villain's nuts. When the turn gifts SB new nut combos (A, K, Q, J), your big bet donates into a range that just got stronger. On overcards: size down or check. On bricks: maintain the plan.

Solver+ turn strategy after BB bet 80% flop on 9-5-3-2 brick: All In (18.2%), Bet 12.48bb (48.5%), Check (33.3%)

BB's turn range split on 9♥5♦3♣ 2♥ brick after 80% flop c-bet in Solver+

Pot ~28.80bb · Stacks ~85.60bb · SPR ~2.97

Both ranges are wider. BB's value range is thinner and SB's calling range is more diverse. SB is even more passive than Path A — CHECK ≥99% on overcards and bricks.

BB HandTurn ActionSizingNotes

54sCheck ~60%One-and-done equity denial on flop

When BB doesn't have the nut advantage but wants to deny equity, a micro-denial bet (20–30% pot) is the right play on brick turns. It's a micro-commitment that advances equity without building an unnavigable pot.

BB's Turn Barrel Frequencies (after SB checks, which is ≥98%):

BB continues barreling 47-64% with a clear preference for 80% pot sizing.

SB's XR ranges and BB's responses are covered in Section 5. Here we focus on turn continuation after the raise.

Turn After XR vs Big Bet — Effectively Committed

Pot ~8,064 with ~4,432 behind. SPR 0.55. Nearly every hand either jams or check-folds.

HandTurn ActionLogic
TTJam any turnMust deny before overcards arrive. Only loses to sets.
A9sJam bricks, check overcardsStrong TPTK. Check A/K/Q turns that scare.
K9sJam bricksTop pair. Fold to 3-bet if BB came over the top on flop.
JTsJam on gin cards (Q, 8)Check-fold blanks. Semi-bluff budget spent.
AJsJam if A or J landsCheck-fold blanks. Bluffing budget exhausted.
A5s / A2sJam if A or wheel card hitsGive up on blanks.

Turn is simplified at SPR 0.55: No thin value, no block betting — the pot is too committed for nuance. Jam value, check-fold missed semi-bluffs.

Turn After XR vs Small Bet — Room to Maneuver

Pot ~3,600 with ~7,360 behind. SPR ~2.04. Genuine decisions about barrel sizing and card impact.

SB's Turn Continuation by Hand:

TTBarrel 60-75% pot on bricksCheck overcards. Still the must-protect overpair.
A9sBarrel bricks for valueOn A turn → bet big (two pair). Check bad overcards.
33, 99Barrel 50-66% on any turnThree streets of value. Can slow-play bricks to let BB catch up.
76sBarrel on 4 (straight completes)Check-evaluate blanks — 7-high has minimal SDV. Give up on overcards.
K9sBarrel bricks 50-60% potOn K turn → bet big (two pair). Cautious on A turn.
A4sBarrel if A hits or straight completesCheck-fold blanks. Ace blocker helps as bluff.
Q9sBarrel bricks cautiously 33-50%Check overcards.
66Barrel selectivelyCheck most turns for SDV.

Turn Card Impact After XR vs Small:

Turn CardSB StrategyLogic
Brick (2,4,8)Barrel 60-70% with TT/A9s/sets/K9s. Semi-bluff 76s on 4/8.Nothing changed. SB's range advantage holds. Apply pressure.
AceBarrel A9s (now two pair). Check TT/K9s. A4s improves.Ace helps SB's A9s and A4s but hurts TT badly. Polarize: bet improved hands, check the rest.
KingBarrel K9s (now two pair). Check most others. TT cautious.K benefits K9s dramatically. SB can overbet with K9s for value.
Queen / JackBarrel TT for protection. Sets continue. Semi-bluffs check.Overcards threaten TT — must continue denying. 76s loses value as a barrel.
6 or 776s barrels big (two pair/straight). All value continues.Best card for SB's semi-bluff region. 76s becomes nutted.
9, 5, 3 (pairs board)Sets → quads/full house (bet big). TT/A9s check cautiously.Board pairing favors SB's set-heavy XR range enormously.

The key difference between the two XR paths: vs the big bet, SB's range is narrow (TT + A9s dominated) and the pot is committed — turn play is automatic. Vs the small bet, SB's range is wider and includes sets + semi-bluffs with SPR ~2.0 remaining — turn play involves genuine decisions about barrel sizing, card impact, and whether semi-bluffs continue or give up.

8 River Strategy: Solver Data & Heuristics

At the river, every hand falls into exactly one of five classes. The classification determines your mandatory play — there's no judgment call, just execution.

ClassDescriptionEquityMandatory Play
A — NutsCannot lose~100%Distribute across all bet sizes
B — Thick ValueBeats villain's thinnest value bet~80%Can trap (check-raise) or bet for value
C — Thin ValueLoses to villain's thinnest value bet~55-66%Mandatory block bet (OOP) or standard bet (IP)
D — ShowdownToo weak to bet, wins at showdown~30-50%Mandatory check
E — AirCan only win by bluffing~0%Fill bluff "suitcase" from bottom of range up

🔑 THE TWO CRITICAL BOUNDARIES

B vs C: Ask "What is villain's thinnest value bet if I check?" If your hand beats it → Class B (can trap). If your hand loses to it → Class C (must bet). On this board, villain's thinnest value bet is typically Q9s or J9s. If you beat Q9s (e.g., K9s), you're Class B. If you lose to it (e.g., 88), you're Class D.

D vs E: Ask "What is my strongest bluff?" Below this hand → Class E (bluff candidate). Above → Class D (mandatory check). On this board, 22 or 44 are often the boundary — below them is pure air.

River Principles for This Spot

OOP Block Bet Theory (SB):

  • Thin value → mandatory block bet (10-33% pot)
  • Sizing follows equity: 55% = 10% pot, 60% = 25%, 66% = 33%
  • Include traps (sets) in checking AND betting ranges
  • Trap ratio shifts to ~1:2 at 25% pot block bet
  • Never jam thin value — small bets maximize profit

IP Rules (BB):

  • Never bet below 50% pot — break-even threshold for reopening
  • Default sizing: 66-75% pot for both value and bluffs
  • Overbet only with surplus nuts on dramatic rivers
  • Check back all SDV — IP can end the hand for free

River by Path — Solver Data

Path A River: After BB Bet 80% Flop, SB Called

Two sub-scenarios depending on what happened on the turn. When BB checks the turn, their range is capped — no overpairs or strong value stayed passive. SB's range is uncapped.

SB's River Action After Both Check Turn (Pot ~49.92bb, Stacks ~75.04bb):

Board: 9♥ 5♦ 3♣ 2♥ (brick turn)

8♦ completes38%48%15%
A♥ overcard79%2%19%
2♦ brick62%38%1%

Key Pattern: Sizing Is Polarized

SB uses either ~40% pot or all-in with almost nothing in between. This is the hallmark of a range-vs-capped-range river: SB has the nuts or nothing. Straight-completing rivers (6♠, 8♦ after 7♥ turn) see 62-64% continuation — SB holds 76s, 87s, 98s and barrels credibly.

When BB Triple-Barrels (Flop 80% → Turn Barrel → River Bet):

SB's calling range has been filtered to sets, strong pairs, and the best bluff-catchers. This is the most polarized river spot in the entire hand tree.

BB Acts on River After Triple-Barrel Line (SPR ~0.83):

Board: 9♥ 5♦ 3♣ 2♥. BB bet 80% flop → barreled turn → acts on river. Only sizing is all-in.

K♦ overcard25%75%
T♣ overcard22%78%
7♠ straight39%61%
4♦ connects44%56%
2♦ double brick32%68%

Key Pattern: Shove Frequency by River Card

T♣ and K♦ trigger the highest shove frequencies (75-78%) — these overcards don't improve SB's calling range. A♥ is the lowest shove at 52% because the Ace improves some of SB's remaining hands (A9s, A5s).

BB Responds to SB's River Bet (After Both Check Turn):

Board: 9♥ 5♦ 3♣ 2♥. Both checked turn → SB bets ~40% pot on river → BB responds.

K♦ overcard~40%p39%36%24%
7♠ straight~40%p54%29%17%
2♦ double brick~40%p62%17%21%

Key Pattern: BB's Delayed Aggression

BB folds 39-62% overall. The 2♦ brick triggers the highest fold frequency (62%) — BB's capped range has nothing to call with on a blank runout. BB raises 17-24% with sets and two-pair that checked back the turn for deception.

Path B River: After BB Bet 25% Flop, SB Called

SB checks the turn ≥98% of the time. The river plays out very differently depending on whether BB barreled or checked behind on the turn.

Both Check Turn (2♥ brick) → SB Acts on River

Pot 28.80bb, stacks 85.60bb. BB's turn check capped their range — SB can probe with value.

The most commonly missed play at NL100-500: Block-betting thin value on low boards. Pairs of 3s and pairs of 5s on 9-high boards should block-bet but are almost always checked.

Bluff Selection — The Inversion Rule:

Prefer hands with one overcard + busted backdoor over two overcards. Two-overcard hands (KQo) have too much SDV to waste as bluffs AND they block the opponent's folding range.

BLUFF SUITCASE ORDER (fill from the bottom up):

1st Busted gutshots with no pair — A4s that missed, pure air
2nd Overcard hands with zero SDV — QJo that bricked everything
3rd Only if suitcase isn't full: weak pairs with marginal SDV (44, 22)

BB Barrels 80% Turn → SB Calls → SB Acts on River

Deep-Street Pot Geometry Confirmed

At SPR ~0.84, SB's range is already defined — hands that called the turn barrel are sets and strong pairs that want to check-call BB's potential third barrel, not lead into it. Only the Ace triggers a shove (49%) because it dramatically improves SB's calling range.

BB Acts on River After x/x Turn (SB Checks to BB):

Board: 9♥ 5♦ 3♣ 2♥. BB bet 25% flop → SB call → x/x turn → SB checks river → BB acts. Pot 28.80bb, stacks 85.60bb.

Key Pattern: Sizing Selection by River Card

K♦ is BB's best bet card (43% total, 40% at 90% pot) — the King doesn't improve SB's range. 4♦ is uniquely a small-bet card (45% at 35% pot) because it connects draws and BB wants thin value. All other river cards default to 90% pot as the primary sizing.

Path C River: After BB Check-Back — Three Solver Scenarios

Path C produces the widest ranges and most varied river spots. The solver was queried on three distinct scenarios.

Both check flop AND turn (x/x/x/x). SB acts on river.

Board: 9♥ 5♦ 3♣ 2♥. Pot 19.20bb, stacks 90.40bb. Ranges are very wide — this is thin-value paradise.

K♦ and J♣ are the best probes (43-44% bet, mostly small). A♥ and 4♦ are check-heavy.

SB probed 40% pot on 2♥ brick, BB called. SB acts on river.

Pot 34.56bb, stacks 82.72bb. This is the critical line — SB continues far more often than "one-and-done."

4♦ connects81%1%18%

"One-and-Done" Probe is NOT GTO

SB continues on 5 of 6 river cards tested, often above 50%. The solver strongly disagrees with giving up after probing. Key patterns:
7♠ = strongest continuation — 85% bet across all sizes (7% all-in). Straight completers are the best barrel cards.
T♣ and 2♦ = strong continuations — 62-67% bet. Run-outs that don't change the board favor the aggressor.
K♦ = small-only continuation — 36% bet, all at 40% pot.
A♥ = polar — 32% bet, but skips small sizing (25% at 95%, 6% all-in).
4♦ = check-heavy — 81% check. The 4 connects too many draws.

Solver+ SB river strategy after probe and call on brick runout: All In (0%), Bet 32.83bb (8.2%), Bet 13.82bb (52.6%), Check (38.2%)

SB's river range split after probe→call on brick runout in Solver+ — continuation far from "one-and-done"

Both check turn, 9♠ pairs the board. SB acts on river.

Path D River: After SB Check-Raised the Flop

The river after a check-raise depends entirely on which flop sizing SB raised against. The two paths diverge dramatically.

SPR was 0.55 entering the turn — most hands resolved before the river.

After SB's flop XR and a turn jam or call, remaining stacks are minimal. The river is almost always an all-in or a trivial decision. If somehow both players check the turn (rare at this SPR), the river plays out simply:

SB HandClassRiver ActionNotes
TTA/B — NutsJam remaining stackSB's overpair — always gets it in. Only loses to sets that slow-played.
A9sB — ThickJam remaining stackTPTK. Ahead of BB's entire continuing range except overpairs.
K9sB/CJam if improved, check if notOn K river → jam (two pair). On blanks → thin jam at this SPR.
JTs (bricked)E — AirJam as bluff if missedBusted straight draw. Last chance to represent the overpair line. Only bluff if straight bricked.
AJs (bricked)D/ECheck-foldA-high has marginal SDV at this pot size. Not enough to bluff with.

In practice, this river rarely happens. At SPR 0.55, the turn action (jam or fold) resolves 90%+ of hands. The remaining river spots are trivial: if you have value, put it in. If you have air, your last bluff chance is a small remaining stack shove.

SPR ~2.0 entering the turn → ~0.8-1.2 entering the river after a turn barrel.

This path produces meaningful river decisions. After SB's flop XR (to ~1,200) and a turn barrel (~50-66% pot), the pot is ~7,200-8,400 with ~3,600-5,200 behind. SB's range is polarized between value that barrelled and semi-bluffs that continued.

T9s (top pair)Fold to jam, call smallFacing a polarized range. T9s is a bluff-catcher at best. Fold to large sizing.

River After XR vs Small: The Polarization Payoff

SB's check-raise on the flop set up a three-street value plan for sets and TT, with semi-bluffs (76s, A4s) as the natural bluff candidates. By the river, the range is cleanly polarized: nuts or air. Sets and TT jam for value. Missed draws either bluff (if they have good blockers) or give up. There's very little thin value — the XR path compresses the hand into a binary decision.

Solver-Based River Calling Framework

Before calling any river bet, evaluate using pot odds and blocker logic — not just hand strength:

  1. What pot odds are you getting? (This determines the equity threshold for a profitable call.)
  2. Does your hand block villain's value range? (Blocking value → their bet is more likely a bluff → call.)
  3. Does your hand block villain's bluff candidates? (Blocking bluffs → their bet is more likely value → fold.)
  4. Is villain's value range plausibly present on this runout? (If the board didn't change, the flop/turn ranges persist.)
  5. Does your hand have enough equity against villain's full betting range? (Use the 5-class framework above.)

Blocker logic > raw hand strength at the river.

A hand that blocks villain's value (holding a 9 on this board) is a better call than a hand that blocks villain's bluffs (holding a J), even if the J-hand is "stronger" in absolute terms.

Position-Dependent River Play: OOP vs IP

OOP (SB) River Play

  • Use multiple block-bet sizes (10%, 25%, 33% pot)
  • Include traps in checking range to prevent overbets
  • Bluff from the absolute bottom of range upward
  • When facing a bet: sort by blocker profile, not hand strength
  • Never jam thin value — small bets maximize profit

IP (BB) River Play

  • Never bet below 50% pot — break-even for reopening
  • Default sizing: 66-75% pot for value and bluffs
  • Overbet only with surplus nuts on dramatic rivers
  • When checked to: bet if you can fold better OR get called by worse
  • Check back all SDV — IP ends the hand for free

The asymmetry is fundamental: OOP uses many sizes (block-betting is mandatory, different equities demand different sizes). IP uses one or two sizes (the 50% pot floor eliminates small bets, and the polar structure demands uniformity).

Common Misconceptions

MisconceptionReality
"BB should range-bet small on dry boards"Wrong. BB uses TWO sizes on 953r. Range-betting 25% leaves QQ/JJ/TT fatally vulnerable to overcards.
"Always check-raise sets on the flop"Wrong vs the big sizing. Sets slow-play 100% vs 80% pot. But they DO raise vs 25% (33 raises 64%).
"TT should just call — it's not strong enough to raise"Wrong. TT raises 90% vs big and 84% vs small. It's SB's ONLY overpair — uniquely valuable for protection.
"AA/KK should always bet big as 3-bettor"Wrong on this board. AA bets 25% pot (43.6%) more than it bets big (27.8%). Not vulnerable to overcards.
"MDF says I should call here"MDF is a GTO constraint, not a recommendation. Use pot odds and blocker analysis for river calling decisions.
