Holdem table

On the button three-handed, 56o is a standard wide open; raising to 300 builds fold equity and lets me play position postflop rather than limping into a multiway pot.

J4o is too weak to continue out of position against a button open; folding avoids a dominated, poorly connected hand.

K9o is a marginal hand but the price is cheap to see a flop from the big blind against a single raiser.

No pair or strong draw with King-high; checking to see next card cheaply.

I hold an open-ended straight draw (any 4 or 9 completes it) with position after the big blind checked. A modest continuation bet leverages fold equity and builds the pot while my draw remains disguised.

King-high with no pair or draw on a wet-ish board facing a bet; not worth continuing.

A2o is easily dominated and too weak to call or open from the button for 100 chips into a 150 pot. Folding preserves the full stack.

With the button folded, only the big blind remains; a standard steal raise with a suited king can pick up the pot or see a cheap flop in position-like heads-up spot.

5-7 offsuit is one of the worst hands to defend against a raise, especially out of position with little straight or flush potential. Calling 200 into a small pot with poor equity realization is -EV, so folding is clearly best.

Cheap price to see a flop in position with a speculative hand; not strong enough to raise.

Only 50 more to call into a 250 pot (5:1) in a 3-way limped pot, so seeing a flop with 6-8 is cheap and has some connector playability; folding saves little and raising OOP with this weak hand is unattractive.

25 offsuit is too weak to raise, and checking is free as the big blind with no bet to call.

I only hold middle pair (8s) on a monotone J-9-8 flop with two players behind in a limped pot; checking keeps the pot small and avoids bloating it against likely flush draws and made flushes.

I have no pair, draw, or overcards on a coordinated flop, so checking is the only sensible free option.

Both opponents checked, showing weakness; my mid pair can bet for value and protection against flush/straight draws.

2c5h has no pair and no diamond draw on a monotone 9-8-J flop, so calling 150 is pure waste. Folding preserves the stack for better spots.

K8o is well within a 3-handed button opening range, and a 3x open builds fold equity while keeping the pot manageable if a blind plays back.

Pocket sixes is a solid small pair to set-mine against a button open. Calling 250 into a 450 pot keeps the hand cheap and lets me see a flop before committing more.

J5 offsuit is a weak hand facing a raise and a call; not worth continuing.

I have a set of sixes on a connected, two-diamond flop, so I bet about 70% pot for value and to charge straight and flush draws.

I have top pair (eights) with a king kicker and position on the donk-bettor. On this draw-heavy board (diamonds and straight possibilities), calling keeps the pot manageable and lets me reassess on the turn rather than bloat it against a lead that often signals a made hand or strong draw.

I hold trip eights with the K kicker on the 4d-6d-8c-8h turn, so I bet ~70% pot for value against overpairs, two pairs, and flush/straight draws; the opponent's fallback check also suggests weakness I can attack.

I have sixes full of eights on a paired board, losing only to quads. Seat 1's turn bet is value or a draw, so I raise to 4000 to build the pot while keeping worse hands in.

J7o is playable from the button in three-handed poker, so I open to 2.5bb to take the initiative with position rather than flat-calling.

T7 suited is weak offsuit-ish out of position facing a raise; folding preserves chips.

Only 150 more into a 400 pot (~27% needed) against a wide 3-handed button range, so defending 87o from the big blind is cheap and has adequate equity even out of position.

I hold king-high with a gutshot (any 5 gives me the nut straight), so checking out of position takes a free card against the preflop raiser rather than betting a hand with little fold equity on a king-high board.

I have no pair or draw on K-6-4, but as the preflop raiser I have a range advantage and the big blind checked. A small c-bet can take the pot down cheaply.

Small stab into a 550 pot; my gutshot (any 5 makes a straight) plus strong implied odds against a preflop raiser's K-heavy range justifies peeling one street cheaply, folding to further aggression.

I have jack-high with no pair, draw, or meaningful blockers, and the opponent already called a flop bet. Checking is free and avoids turning a weak hand into a bluff.

Jack-high has no pair or straight on this connected board, so there is no value in betting. Checking back realizes the pot without turning a weak hand into a bluff.

K6 suited on the button is a decent steal/semi-speculative hand; raise to isolate and take initiative against blinds.

Nine-two offsuit has almost no equity or playability against a button raise, and calling 200 more out of position or bluff-raising with no fold-equity guarantee is -EV. Folding saves chips for a better spot.

K9 offsuit is too weak to defend out of position against a button open; folding avoids a dominated, poorly playable spot.
