Hold'em table

A5o is playable as a button open in three-handed; a 2.5bb raise takes the initiative and has fold equity versus the blinds.

QTo has enough equity against a 2.5x open in 3-handed play, and the pot odds justify completing from the small blind despite being out of position.

I whiffed the flop with Q-high and only a weak running straight possibility, out of position against the preflop raiser. Checking keeps the pot small and lets me fold cheaply to aggression or realize a little showdown equity if he checks back.

I have bottom pair with an ace kicker on a jack-high flop after the preflop caller checked. A small c-bet takes the initiative, denies equity, and can get value from worse hands.

I hold Q-high with only a runner-runner broadway draw on J-7-5, and the preflop raiser c-bet into me. Calling 200 with almost no equity is -EV, and bluff-raising with zero showdown value is too risky with no reads in hand 1.

Jack-five offsuit is too weak to play from the button against two blinds with no prior reads; folding preserves chips for better spots.

Heads up now that button folded; J8o is playable cheaply from SB against BB, so I complete rather than raise or fold.

K2o is too weak to raise against a completed small blind, and checking is free. I take the flop and reassess.

I have an open-ended straight draw with J8 on a T-4-Q board; a small continuation bet builds the pot while I retain good equity to improve to a straight.

King-high with no pair or draw is too weak to continue against a flop bet. Folding avoids paying to chase one overcard.

7-3 offsuit is a weak hand not worth playing from the button facing a raise; folding preserves chips.

Button folded, so this is heads-up versus the big blind. A2o has enough equity to complete for 50 into a 150 pot rather than fold or inflate the pot out of position.

K8o is a marginal heads-up hand; checking keeps the pot small and I retain postflop position against the small blind's likely weak limping range.

Ace-high with no pair or draw on T-9-Q has little showdown value and no strong bluff equity, so I check rather than bet into a board that connects with many hands.

I have king-high with a gutshot to the jack-high... actually king-high straight (K-Q-J-T-9) on the Q-T-9 board, and the limper checked the flop showing weakness. Checking realizes my free-card equity cheaply rather than bluffing into a pot with only ~4 clean outs.

I have only bottom pair on a connected turn, so there is little value in betting. Checking keeps the pot small and realizes my showdown equity for free.

I hold only king-high on Q-T-9-2, so taking a free river is best: the limper has checked twice showing weakness, and checking preserves showdown value while giving me outs to a king, eight, or jack. Bluffing this small pot out of position has thin fold equity if any pair calls.

I have only a pair of deuces on a king-queen-ten-nine board, so a bet mostly gets called by better hands and folds out worse ones I already beat. Checking to showdown is the highest-EV line.

I hold top pair king with a weak kicker on a board full of better kings (KQ/KJ/KT/K9) and Jx straights, so betting only gets value from hands beating me; checking to realize showdown value for free is best.

J9o is playable from the button in three-handed poker, so I open to 3bb to take the initiative with position rather than flat or fold.

Pocket sevens are too strong to fold to a 3x button open at 100bb; calling keeps the pot small, preserves set-mining implied odds, and avoids bloating a marginal spot out of position with the big blind still to act.

Weak offsuit 4-2 facing a raise and a call; not worth continuing from the big blind.

I flopped a set of sevens on a coordinated board with flush and straight draws, so I bet around 70% of pot for value and to charge draws rather than checking and giving a free card.

J9 missed the flop completely with no pair or draw, and calling 500 into 1200 is not justified against a flop bet.

A2s is a solid suited ace to open from the button 3-handed; raising builds the pot with position and fold equity.

2-5 offsuit is a weak hand facing a 3bb raise; folding is correct here.

J4 offsuit is too weak to continue against a button open, so folding is the highest-EV option.

On the button with a playable King-high hand in a 3-handed pot, raising to apply pressure on the blinds is standard.

Q2 offsuit is too weak to continue out of position against a button open, so folding is the best play.

Ace-four offsuit is too weak to defend out of position against a 2.5bb button raise; the ace is likely dominated and the hand plays poorly postflop.
