ThinkGTO Weekly · May 4 — May 10, 2026 | | Lead Story · The Field's Missing Move When BB won't check-raise high-card flops, you should bet biggerOn A-high, K-high, and Q-high flops in single raised pots, Solver+ data shows BB check-raising the in-position c-bet around 7–15% of the time depending on sizing. In live $2/$5 and rec-heavy mobile pools, the actual rate sits closer to 1–3%. That gap rewrites every postflop sizing decision IP. When villain almost never raises, the structural reason GTO caps your overbet at 5% disappears — and the line that prints is to use the larger sizing far more often, with wider value combos and fewer give-ups. | | Strategy Spotlight Three reasons the population leak compounds- Made-hand bias. Recreational BB callers reserve check-raises for two pair plus. The fringy combos with backdoor equity that the solver uses to balance? They check and fold or peel.
- The ace bias. Players assume any in-position bet on A-high is for value, so they fold their bluff-catchers too often and never imagine raising.
- No retaliation cost for you. The reason equilibrium caps the overbet at 5% is the threat of a check-raise putting your bluffs in a torture spot. Remove the threat and the cap relaxes — for value and for bluffs.

BB checks 98.3% of the time. At equilibrium, BTN's response splits across check back 32.7%, bet 1.4bb (25% pot) 62.2%, bet 4.4bb (80% pot) 5.1%. Against a population that check-raises <3% on A-high (vs the solver's 15.4% against the small bet, 7.8% against the big one), the right adjustment with A♣K♣ is to collapse those frequencies and use the 80%-pot sizing far more often. The threat that holds the small-sizing equilibrium together is gone — and top pair top kicker on a bone-dry texture wants the bigger pot when villain caps their range to calls and folds.

Drill It · Tool Tip Make the sizing decision automaticReading about the exploit is one thing. Repping it until the sizing fork resolves in under a second is what closes the gap between knowing and earning. Postflop+ serves you the BTN-vs-BB SRP scenarios in the exact configurations that matter — A-high, K-high, low-board — with the GTO answer revealed after each decision. Run a 20-rep block on A-high flops with the small/large sizing fork in mind and your live-table speed jumps without you noticing. Want the math underneath the sizing call? MDF Calculator gives you the threshold below which villain is over-folding to a given bet — useful when planning whether to push to overbets later in the hand. |

This Week in Poker What's moving in the strategy worldWSOP prep season is here. With six weeks until the 2026 series, the coaching world is shifting into prep mode — short-stack reshove charts, ICM and pay-jump theory, and live-specific exploits are dominating the published content. If you're heading to Vegas, lock in your study plan now while the spots you'll see most are still fresh. The bubble-folding controversy. A WSOP Europe stone-bubble hand where a big stack folded to a short-stack jam set off another round of soft-play accusations — and the ICM math, predictably, says the fold was mandatory. The chips a big stack risks are worth more than the chips it can win, and that asymmetry doesn't care about table optics. |
