SECOND NATURE POKER

Big ideas

• ▸Equity is not money: position, hand shape, stack depth and range edge decide how much of it you actually keep.
• ▸On the river, B/(P+2B) is both the share of bluffs a balanced bet can hold and the price the caller gets.
• ▸MDF is a floor against raises, not a duty against every bet; the player with the range and nut edge makes you fold more.
• ▸Range edge decides how often you bet; nut edge decides how big you bet.

Big ideas

• ▸Stack depth changes what a hand is worth: short stacks reward high cards and blockers, deeper stacks reward playability and nut potential.
• ▸Every raise has a break-even fold rate, risk divided by risk plus reward; antes cut it, so a button min-raise needs only about 43% total folds.
• ▸Below about 25bb, label every raise in advance as raise-fold, raise-call or jam, and stick to the plan.
• ▸Small pairs flip roles with depth: jam 22-33 at 15-20bb, fold them first-in at about 25bb, open them again near 40bb.

Big ideas

• ▸The raiser in position realizes far more of its equity than the big blind, so bet often and mostly small as a baseline.
• ▸Choose size by the job: small bets fold hands with no backdoors, big bets protect vulnerable pairs and fold better hands.
• ▸Opener position changes frequency most on high-card boards: early position bets nearly every king-high flop, the button checks far more.
• ▸Depth reassigns roles: deep on wet boards draws bet and naked top pair checks; at 15bb top pair bets and unpaired draws check.

Big ideas

• ▸Out of position against a positional flat, check is the default, and the later the opener's seat, the less it bets.
• ▸Count the dust: the more unplayable hands in your opening range, the less you can bet high boards.
• ▸Monotone boards are a flush-count problem: if many of his suited hands are blocked, bet small; if few, check and slowplay.
• ▸Blind defense is not MDF: against a bet from the stronger range with position, the blind folds far more than the formula says.

Big ideas

• ▸Range edge decides how often you bet and nut edge decides how big; an equity edge without nuts earns only a tiny bet.
• ▸Equity is not EV: the side holding hands the other cannot have collects far more than its equity share.
• ▸Every turn card asks whose calling range it hit, so count the actual combos before calling a card a blank.
• ▸Turn overbets need three things at once: nuts they cannot have, a visibly capped range, and bluffs that profit from folds.

Big ideas

• ▸SPR runs the chapter: at 40bb a 3-bet pot flop is commit-or-fold, at 100bb there are still three streets of play.
• ▸60bb plays like 100bb in frequencies, not like 40bb, with a few selective flop shoves on wet boards.
• ▸The 3-bettor does not always have the edge: high boards favor it, low connected boards favor the caller's suited connectors and pairs.
• ▸Use few sizes: a small bet and a shove at 40bb, a small bet and a half-pot-to-pot bet at 100bb.

Big ideas

• ▸Chips are not dollars: the more you hold, the less each chip is worth, so the chips you risk cost more than the ones you can win.
• ▸Risk premium is the extra equity you need beyond pot odds for an all-in, and it is biggest when you are covered.
• ▸Always ask who covers whom: the same all-in costs the covered stack far more than the covering one.
• ▸ICM pressure only works on opponents who respect ICM; against chip-EV callers, value-bet and drop the bluffs.

Big ideas

• ▸Exploit by moving one hand class, starting with hands that already mix; a few extra folds can flip a mixed node to pure.
• ▸Size opposite to what he puts in: if he raises a lot, bet small with strong hands; if he never raises, bet bigger and thinner.
• ▸Pools fold unpaired trash to small bets, leads and overbets, do not fold pairs and gutshots on wet boards, and under-bluff rivers.
• ▸Maximal exploits cost the most when wrong, so default to small adjustments a good opponent cannot punish, and revert when he reacts.
