Hold'em table

Button with J8o in three-handed; a small open uses position and fold equity rather than calling a dominated offsuit hand.

Q3o is far too weak to call 200 more against a 2.5x raise out of position; folding is clearly best.

Pocket fives in the big blind facing a 2.5x button open with 100bb effective; calling is standard for set-mining and playing a pot in position-disadvantaged but with good implied odds, while 3-betting a small pair is marginal.

Pocket fives on an Ace-King flop out of position against the preflop raiser; betting has little value and I'd be folding to pressure. Check and see what the raiser does, folding to a bet most of the time.

Jack-high with no pair and no draw on an ace-king board has almost no equity, so checking back avoids bloating the pot with pure air.

Button checked back a dry AK2 flop showing weakness; I have a gutshot to the wheel plus a small pair, so a probe bet can take the pot now and keeps outs if called.

Jack-high with no pair or draw on an ace-king board has no reason to continue against a turn bet.

K2 offsuit is a weak hand facing a raise-free limped pot but still not worth playing out of position advantage; folding preserves chips for better spots.

Button folded, so it's SB vs BB heads-up; QTo is well within a standard SB open-raising range against the big blind. Raising to 3bb takes initiative and denies the BB a free flop.

95o is too weak to continue out of position against a 3bb raise; folding avoids a dominated, low-equity spot.

53s on the button in a 3-handed game is a reasonable open-raise; suited connectors play well in position with 100bb stacks and the blinds will fold often enough.

KJo is ahead of a typical button open and plays better with initiative, so I 3-bet to 850 rather than call out of position.

5h6s is a weak suited-connector out of position facing a raise and re-raise; folding avoids playing a marginal hand deep in a bloated pot.

5d3d suited is too weak to continue against a 3-bet to 850 out of position; calling 600 more with a hand that flops poorly and plays badly vs a 3-bet range is -EV.

Q5 offsuit is too weak to call or open from the button against two live blinds; folding avoids dominated spots and negative EV.

T2s suited in the small blind heads-up is worth completing for 50 more; cheap flop potential against the big blind.

J5o in the big blind facing a limp from the small blind; checking takes a free flop in position with a weak hand rather than bloating the pot.

Bottom pair with a weak kicker on a scary three-flush board; checking to control the pot and avoid building a big pot out of position.

Jd5s with no club on a monotone board has little equity and no backdoor flush; checking back the limped pot keeps it cheap and avoids bloating a pot where I'm often behind.

I hold two pair (nines and twos) but the board is monotone in clubs, so I have no club draw and my hand is vulnerable. Checking keeps the pot small and avoids bloating it against a flush or better nine.

I have jack-high with no draw on a paired, three-flush board; opponent has shown weakness but betting with nothing into a 200 pot risks a check-raise and my hand has little showdown value. Taking the free card is fine.

I hold T-high with a pair of nines on board (9s9cQ2 4), so my best line is a free showdown; betting T-high into the BB risks a raise with no fold equity worth chasing.

Jack high with no pair on a paired, flush-possible board; opponent has checked every street so a bluff might work but checking down is fine with low pot and showdown value is nil—actually a small bet could fold out hands like 5x/6x but risk is unnecessary; check.

Button folded (fallback), so it's SB vs BB heads-up with J7o, a reasonable hand to open-raise against a single opponent; raising takes the pot down often and builds a pot in position-neutral blind battle.

62 suited is too weak to continue against a 3bb open, even heads-up with the button already folded. Folding saves chips for better spots.

A7o on the button in a 3-handed game is a standard open; raising to 2.5bb to take initiative against the blinds.

Pocket jacks are well ahead of a button open, so I 3-bet to 900 to build the pot and deny equity rather than flat from the small blind.

A6 offsuit is dominated against a 9x 3-bet from seat_1 after seat_3's open; folding is clearly best.

A7o facing a 3-bet from the small blind out of position is a standard fold; it's dominated by much of a tight 3-bet range and plays poorly postflop.
