Four Bet Strategy by Stack Depth

Four Bets Are a Stack Depth Problem

Your 4-bet strategy is not a hand chart. It is a commitment model.

At 100bb, SPR collapses fast. Your 4-bet range can be tighter and more value dense.

Deep, your opponent can call more, trap more, and punish bad sizing. Your Equity Realization (R) becomes the whole game.

• 100bb, default leans Linear vs. Polarized ranges depending on position and rake.
• 150bb to 300bb, default moves more Polarized, because calls expand and postflop edges matter.
• Your goal is to keep your range Uncapped while forcing villain into Capped vs. Uncapped mistakes.

TPP Exploit Framework

• The Exploit, attack players who mechanically 3-bet then overfold to 4-bets.
• The Risk, if you push volume bluffs into sticky pools, you torch EV.
• The Counter, when they start calling more 4-bets, tighten bluffs and shift to postflop value.

Range Architecture, Linear vs. Polarized

You pick Linear vs. Polarized ranges based on how villain responds.

If villain 5-bets rarely and calls too much, you go Linear. If villain 5-bets aggressively and folds to 4-bets, you go Polarized.

• Linear 4-bet, QQ+, AK, add JJ, AQs, AQo versus wide 3-bets.
• Polarized 4-bet, value block plus bluffs with strong Blockers/Unblockers.
• Best bluff candidates block value, unblock folds. Think A5s-A2s, sometimes KQs.

Your bluff density is bounded by villain’s continuing range. You do not get to bluff because you feel like it.

If your pool calls too wide, your bluff frequency must drop. Online pools do not obey your ego.

TPP Exploit Framework

• The Exploit, versus call heavy 3-bettors, build Linear and value print.
• The Risk, if you go too linear in a 5-bet heavy environment, you get forced into negative EV stacks.
• The Counter, if they start 5-bet jamming wider, reintroduce Polarized with blocker bluffs.

100bb, The Clean 4-bet Game

At 100bb, the tree is compressed. A 4-bet threatens stacks immediately.

Your opponent’s call range is narrower. This reduces their positional advantage and improves your Equity Realization (R).

• Default size IP, 4-bet to 2.2x to 2.5x of the 3-bet.
• Default size OOP, 4-bet to 2.4x to 2.8x of the 3-bet.
• When rake is high, widen value slightly, reduce thin bluffs. Respect the Rake-drag.

At 100bb, a lot of players make a consistent mistake. They call 4-bets with hands that cannot realize.

Punish that by keeping your range uncapped and your sizing coherent.

Scenario Box

Hero Hand: 8♠7♠

Flop: K♣7♥3♠

Action: CO opens. BTN 3-bets. Hero in BB considers 4-bet vs call at 100bb.

• With 87s OOP, a cold 4-bet is usually a leak at 100bb.
• You block nothing. You unblock folds. You create a low Equity Realization (R) pot OOP.
• Calling is allowed only if price and postflop plan exist. No hope calls.

TPP Exploit Framework

• The Exploit, isolate 3-bet happy regs with 4-bets that skew to value.
• The Risk, if you under bluff, good regs overfold less and outplay you in position.
• The Counter, add A5s-A2s bluffs when they overfold to 4-bets.

Deep Stacks, Calls Expand and R Collapses

Deep, a 4-bet does not force stack off. It creates a high SPR pot with a condensed range.

That means your opponent can call more suited hands and play perfectly in position. Your Equity Realization (R) goes down OOP.

• Deep IP, you can keep some 4-bet sizes smaller to preserve bluffs and deny cheap calls.
• Deep OOP, you often size bigger or become more Polarized.
• You must protect your range from being Capped vs. Uncapped postflop.

Deep is where people punt with dominated offsuit broadways.

Hands like KJo look playable. They are reverse implied odds grenades when you inflate with a 4-bet.

Scenario Box

Hero Hand: K♠J♣

Flop: J♥9♣4♥

Action: Hero opens UTG. BTN 3-bets. Hero considers 4-bet at 200bb.

• Deep UTG OOP, KJo is not a stable 4-bet.
• You get called by better. You fold out worse. That is negative EV polarization.
• If you continue, prefer call with a tight plan, or fold versus strong 3-bet ranges.

TPP Exploit Framework

• The Exploit, versus deep callers, 4-bet less thin. Increase value density.
• The Risk, if you only 4-bet premiums, you become face up and get overfolded against postflop.
• The Counter, protect with a few blocker bluffs, but only the best Blockers/Unblockers profiles.

4-bet Sizing, MDF, and Commitment

Your sizing sets the price of resistance. That directly changes villain’s Minimum Defense Frequency (MDF).

Bigger 4-bets increase fold pressure but worsen your risk. Smaller 4-bets invite calls and increase postflop complexity.

• If villain is overfolding, smaller sizing can print by allowing more bluffs while keeping risk controlled.
• If villain is sticky and in position, bigger sizing reduces their ability to realize with suited junk.
• Deep OOP, bigger sizing protects your range from being run over postflop.

Commitment is math. At 100bb, many 4-bets create a pot that makes a future jam natural.

Do not 4-bet hands you are not prepared to play for stacks when the configuration forces it.

TPP Exploit Framework

• The Exploit, use sizing to punish population leaks, small versus nits, big versus callers.
• The Risk, mis-sizing creates capped ranges and forces you into low Equity Realization (R) lines.
• The Counter, if they adjust by 5-bet jamming wider, tighten bluffs and trap with strong value.

Out of Position 4-bets, Survive the Hard Spots

OOP 4-betting is where most online players light money on fire while multi-tabling.

You cannot autopilot. Your OOP range must be coherent, or tracking software will show a redline collapse.

• OOP, prioritize hands that can continue versus pressure, QQ+, AK, some AQs.
• Bluffs must have elite Blockers/Unblockers. Think A5s-A4s more than random suited connectors.
• Hands like 44 are not automatic continues. Set mining without odds is hope poker.

Scenario Box

Hero Hand: 4♠4♥

Flop: A♣K♥6♠

Action: Hero in SB 3-bets. BTN 4-bets. Hero considers call at 150bb.

• Deep, calling with 44 OOP is usually dominated by Rake-drag and low Equity Realization (R).
• Your implied odds are fake if villain’s range is strong and boards run high.
• Default is fold, unless sizing is small and villain’s 4-bet range is provably wide.

TPP Exploit Framework

• The Exploit, fold more OOP versus tight 4-bets. Stop donating.
• The Risk, if you overfold, aggressive regs print with any blocker combo.
• The Counter, defend with a calibrated mix and add 5-bet jams with the top of range.

Online Pool Adjustments, Rake and Frequencies

Online ranges live under rake and volume. Your 4-bet strategy must match the pool, not a solver screenshot.

In many pools, 3-bets are too linear and 4-bets get too much respect. That is free money if you stay disciplined.

• Versus high fold to 4-bet, increase bluffs using A5s-A2s and selective KQs.
• Versus low fold to 4-bet, reduce bluffs, add value with JJ, AQs in the right nodes.
• Use tracking software to tag who 5-bets, who flats, and who overfolds.

Your frequencies must be robust enough to survive counter play. That means protecting value, controlling bluff density, and preventing your range becoming Capped vs. Uncapped.

TPP Exploit Framework

• The Exploit, data mine with tracking software, then target the pool’s most common response node.
• The Risk, overfitting tiny samples leads to spew, especially while multi-tabling.
• The Counter, when opponents adapt, revert toward balanced Linear vs. Polarized ranges baselines.
