Need ≥ 33.3% equity
Pot odds 2.0 : 1
02

MDF & Bet-Sizing Helper

how: MDF = pot ÷ (pot+bet); bluff α = bet ÷ (pot+bet); their equity-to-call = bet ÷ (pot+2·bet).
bet = 50% of pot
Defend ≥ 66.7%
Bluff must work (α): 33.3%
Their equity to call: 25.0%
03

Outs → Equity

Exact 34.9%
Quick rule: ~35%

Preflop Sizing (bb)

how: 3-bet IP 3×, OOP 4–4.5×; squeeze 4.5–5× +1bb/extra caller; 4-bet IP 2.2× the 3-bet, OOP 2.5–3×; iso 5bb +1/limper.
3-bet 7.5bb
Squeeze: —
4-bet: 16.5bb
Iso vs limpers: 5bb
Static open guide: RFI 2.2–2.5bb · BTN 2–2.2bb · SB 3bb.

Geometric Sizing — set up the river jam

how: SPR = stack ÷ pot; per-street fraction f = ((1+2·SPR)^(1/N) − 1) ÷ 2. Bet f% of pot each street.
Bet 82.3% pot / street
SPR 3.0 · first bet 8.2
06

Bluff Break-Even / Fold Equity

how: pure-bluff FE = bet ÷ (pot+bet). With equity when called E, required fold % = (B − E(P+2B)) ÷ (P+B − E(P+2B)).
They must fold ≥ 39.8%
07

Implied Odds

how: extra you must win later = call ÷ equity − (pot + call). Pot already includes their bet.
Win ≥ 0 more
0.0× the call, on later streets

Range vs Range Equity · study tool

how: Monte-Carlo. Expands ranges into combos, deals the remaining board many times, evaluates 7-card hands. Not instant — run it while studying, not in-game. Syntax: pairs AA, suited AKs, offsuit AKo, both AK, or exact AhKd; comma-separated.

Tap “Run”. Defaults to 40,000 trials; results vary ±~0.5% run-to-run (Monte-Carlo variance).

Blockers / Combos · study tool

how: enumerates every villain 2-card combo (deck − your 2 − board), classifies each on the board (value / draw / marginal / air), and measures how YOUR exact cards remove (block) each category. Bluff: block their value + unblock folds · Thin value: don't block worse calls. Cards: Ah Qs style, space/comma-sep.
Value blocked —
Folds you block (low = good bluff): —
Worse-calls blocked (low = good thin value): —
passivity is the leak · default to aggression
