Poker Wiki : 100 questions-reponses GTO sur le Texas Hold'em

GTO is a game-theoretic equilibrium strategy under fixed rules and information. Its goal is to keep opponents from exploiting you with one-sided adjustments over the long run.

No. Balance is a range-level statistical property, not doing the same action with every hand. Many nodes require mixed frequencies.

No. GTO provides a stable baseline and downside control. Profit still depends on opponent quality, variance, and execution quality.

GTO is the default baseline. Exploitative play is a deviation when evidence exists. A common approach is to use GTO for risk control, then apply small targeted adjustments.

A range is the full set of hand combos a player can hold at a node. GTO decisions optimize against ranges, not one isolated hand.

Combo counts define the weight of hand classes in a range. The value-to-bluff combo ratio directly impacts optimal responses.

Blockers remove opponent strong or continuing combos and change EV for bluffs or thin value bets. They are especially important on rivers.

Polarized ranges contain strong value and bluffs. Merged ranges contain more medium-strength value. Board texture and position shift the mix.

MDF is a quick lower-bound heuristic, not a full strategy. Real decisions also require range distribution, blockers, and future-street realization.

If you call C to win P+C total, the minimum required equity is about C/(P+C). This is the first feasibility filter for calls.

EV is long-run average return. Between actions, prioritize the higher-EV line rather than short-term outcomes in small samples.

Use randomization or simplified rules, such as suit-based splits, clock-based randomization, or preset thresholds, to approximate target frequencies over time.

Acting later gives more information, allowing better pot control and sizing choices. That usually improves strategic flexibility and realization.

Higher SPR creates more future-street branches. Sizing and range construction become finer, and mistakes are easier to amplify.

Lock a preflop baseline first, drill common flop nodes next, then expand to turn and river. Use weekly review loops to fix recurring leaks.

UTG faces the most players left to act and the highest 3-bet/call pressure. Theory therefore requires higher average hand strength.

BTN has positional advantage and blinds already contribute dead money. Many medium hands become profitable with position.

SB plays postflop mostly out of position, so strategy relies more on sizing and protection. Opening width is usually tighter than BTN.

Main factors are opener position, effective stack depth, and rake structure. Earlier opens and higher rake usually narrow BB defense.

It depends on opener range, positions, blocker quality, and postflop realization. It is not a fixed number.

Typical candidates block strong continuing ranges with A or K and have weaker flat-call performance versus 3-bets.

Reduce marginal flats, keep higher realization and stronger continue regions, and avoid being position-pressed in inflated pots.

Check effective stack depth and price first, then your range top and blockers. Many medium-strength hands realize poorly in 4-bet pots.

Suited A-x combines raw equity and blockers, allowing it to take part of semi-bluff and continue structures in 3-bet/4-bet trees.

They gain value with sufficient implied odds and enough opponent pay-off combos. High rake and shallow stacks reduce that value significantly.

They improve with position, deeper effective stacks, and opponent ranges that can be pressured. OOP and shallow stacks require tighter use.

Prefer blocker-relevant combos that can continue on high-card boards, and cut marginal offsuit combos with poor reverse-implied profiles.

At 50bb, all-in thresholds are lower and marginal flats/slowplays shrink. At 100bb, multi-street realization matters more.

No. ICM changes chip utility and risk tolerance. You need model-specific solutions for that environment.

Review when moving stakes, changing platforms, or finding persistent leaks. Stable players often review monthly or by training cycle.

In many single-raised heads-up spots, the aggressor often has range advantage. Small bets apply pressure at lower cost and capture high-fold regions.

Both ranges connect more similarly, reducing unilateral advantage. Bet frequency and sizing rely more on combo-level structure.

Start with nut density and high-flush blockers for both players, then choose between high-frequency small bets and higher check share.

The aggressor does not always retain stable nut advantage on paired textures. Protection and node context drive strategy, so check rates often rise.

Range advantage, nut advantage, and realization. If aligned, frequency can rise; if conflicting, strategy should be more mixed.

Yes, but usually as structured low-frequency actions concentrated on specific textures and combos, not as default behavior.

Mix strong value with semi-bluffs that retain future playability. Avoid one-type-only compositions that unbalance your range.

In multiway pots, equity is more compressed, bluff success drops, value thresholds rise, and overall aggression is usually lower.

Use turn cards that update range advantage to apply pressure, or use combos that gained new equity as semi-bluffs.

Yes, if blocker effects and fold equity are sufficient. If future-street continuation is weak, checking is usually safer.

Over-inflating pots in high-pressure lines. Theory usually prefers size control based on continue ranges and runout stability.

It depends on fold equity and overtake risk on future streets. Most spots require a mix rather than one forced line.

When it has key blockers, opponent ranges contain fold-heavy regions, and you can credibly continue pressure on later streets.

Your check range becomes too weak, turns become attackable, and opponents gain stable exploit windows.

By process metrics: frequencies, EV gaps, and range structure. Short-term outcomes do not validate decision quality.

Compared with flop, turn sizes often increase to magnify equity separation and apply more pressure to marginal continues.

When your combo gains extra equity or blocker quality on turn and opponent flop-calls include compressible regions.

You need sufficient realizable equity, reasonable blockers, and viable win paths when called.

It is set by how often worse hands can pay, not by absolute hand strength. Without a pay range, value frequency should drop.

Prefer combos that block strong continues while not blocking opponent folds.

They control the risk of facing large bets while extracting thin value from part of the worse range.

Combine price, blockers, and value/bluff ratio estimates. Start with minimum defense needs, then select at combo level.

Turn and river options are constrained by earlier range and sizing choices; late improvisation often creates imbalance.

Check blocker quality and opponent range cap first. If blockers are poor and bluff-catchers are plentiful, reduce bluff frequency.

Track long-run call frequency against your river bets and EV. If called too often with persistently negative EV, bluffing is likely excessive.

Compute pot-odds threshold first, then check blocker effects and line coherence before setting call boundaries.

When you hold clear range advantage and opponent continues are capped, overbets can scale both value and fold equity.

If check ranges are too weak, opponents can bet at high frequency exploitatively. Retaining strong hands raises their attack cost.

Whether worse hands pay often enough. If payment frequency is too low, thin value turns negative EV.

Flop EV is intermediate. Final EV comes from full-line performance; single-street edge does not guarantee line optimality.

Common in nodes with clear range advantage and high-frequency betting goals, capturing range value at lower risk.

It balances protection and value and fits many medium-dispersion textures.

It often reflects stronger polarization or higher protection demand, intended to compress marginal continues.

When your nut advantage and combo coverage clearly exceed opponent's and there is a force-fold middle region.

Different combos serve different jobs. Some target thin value, others maximize polarization pressure. Multi-size mixes can raise total EV.

Use preset combo rules within each size and avoid readable patterns such as only big with strong hands and small with weak ones.

Facing larger bets lowers the minimum defense ratio needed, so larger sizings typically increase fold pressure.

Larger sizes usually force continues to narrow toward high-equity regions, while smaller sizes allow wider continues.

They are commonly based on SPR, realization quality, and called-range strength. Too-low thresholds create unnecessary variance.

No. Too many sizes increase execution error. Most practical systems stabilize on 2-3 sizes first, then refine gradually.

Larger sizing can increase fold equity but also investment cost. Low-realization combos are not always suitable for large sizing.

At low SPR, one bet commits more stack and strategy is more direct. At high SPR, you can plan finer multi-street structures.

When you have stable evidence of significant opponent deviation and enough sample support for that conclusion.

Increase executable bluff frequency, especially against marginal defense regions, while preserving minimum structural balance.

Reduce low-quality bluffs, increase value density, and use more direct value lines.

Increase bluff-catching and induce lines, protect check ranges, and avoid blind counter-aggression without blocker support.

Expand steal and positional pressure, but restore stronger continue thresholds once they fight back.

Increase value-entry and isolation quality, and cut marginal bluff lines.

Live games are slower with smaller samples and higher read weight; online pools accumulate samples faster and allow finer strategic granularity.

Set minimum sample thresholds, make low-risk micro-adjustments, and re-check whether EV supports those deviations.

Use small-step iteration, typically 5%-15% frequency shifts first, then continue based on results and sample feedback.

When opponents adapt or evidence fades, return to baseline frequencies. Keep records to avoid running stale exploits.

Each cell gives raise/call/fold frequencies for that starting hand in the selected spot, and the sum is near 100%.

That usually means very low weight in this spot, not missing data. Verify by switching position, action, and stack depth.

They are different decision nodes: opening first in, responding to an open, and responding to a 3-bet. They are not interchangeable.

Fix one position and action first, extract high-frequency combos into drills, then validate postflop execution in Spot Trainer.

Not always. Many blanks are 100% folds or no-data under the current filter. Check filters and legend first.

Check scenario index integrity, full 169-hand coverage, and frequency-sum validation, then spot-audit sampled nodes manually.

Scores are based on EV loss between your selected action and the best action. Smaller EV loss gives higher grades.

Mainly EV-loss thresholds. A+ is usually near-optimal, while B is often acceptable but with clear room to improve.

Aggregate low scores by tags and scenarios, then prioritize recurring error types rather than one-off mistakes.

Short, high-quality, high-frequency sessions usually beat long low-focus sessions. A common pattern is 20-40 minutes daily with review.

No. Learn range advantage, blocker logic, and sizing logic first, then use frequencies for refinement.

Check opponent range at that node first, then your combo role in that range, then compare EV of alternative actions.

It supports hand vs hand, hand vs range, and range vs range. Output equity can be used for decision comparisons.

Opponent ranges, board cards, and card-removal effects change. Equity is conditional, not a fixed constant.

Hand vs Range suits single-hand decisions; Range vs Range suits range-level comparison and strategic direction checks.

First compare equity to pot-odds thresholds for continue feasibility, then apply realization and reverse-implied filters.

It is suitable for in-browser postflop tree setup and strategy viewing. It is not a replacement for offline large-scale cluster solving.

Weeks 1-2 lock preflop ranges, weeks 3-5 drill core flop and turn nodes, weeks 6-8 focus on river and targeted review, with weekly EV leak checks.
