Hold'em table

K2 offsuit is too weak to complete out of position against the big blind, so folding the extra 50 is the lower-variance choice.

A9 suited is a solid button open in three-handed play, so I raise to 2.5bb to take the initiative and fold out weaker hands.

T2o is far too weak to defend out of position against a button raise.

J9s is a standard BB defend against a 2.5x button raise heads-up; calling 150 into a 400 pot needs only ~27% equity and the hand has solid playability with straights, flushes, and top-pair potential.

Top pair jacks with a weak kicker against a preflop raiser heads-up; checking keeps the pot small and lets me evaluate their flop action before committing.

Ace-high with no pair or draw on QJ7; opponent checked a flop they called safe, so a c-bet is likely to get called by better. Check back and reassess the turn.

I have top pair with a weak kicker on a paired board; a small turn bet gets thin value and defines my hand without risking much against seat_2's passive line.

Ace-high with no pair and no draw on a paired Q-J-7 board is too weak to continue against a turn bet. Folding avoids paying off any made hand.

J9o is well within standard 3-handed button opening range, so raising 2.5bb to take initiative with position.

Q5 offsuit is far too weak to defend out of position against a button raise with the big blind still to act; folding preserves chips for a better spot.

46o is too weak to continue against a button open after the small blind folds, so I fold rather than call or raise.

King-eight offsuit is a standard button open three-handed, and raising to 2.5x builds the pot while keeping positional advantage postflop.

2-4 suited is too weak to continue out of position against a button raise, with the big blind still to act. Folding avoids a dominated, low-equity spot.

Getting attractive pot odds of 150 to win 400 to defend the big blind with a pocket pair heads-up against a button open.

I hold an underpair out of position against the preflop raiser, making a check the standard line.

I raised preflop and the BB checked to me on a Q-9-4 board; with king-high and little showdown value, a ~2/3 pot continuation bet leverages my position and fold equity to often win the pot outright.

I hold an underpair on a Queen-high board and have minimal equity against the button's continuation bet.

K7s is playable from the button in three-handed, and opening to 3bb takes the initiative with position rather than flat-calling the blind.

A8s is a strong suited ace in 3-max play; three-betting from the small blind against a button open builds the pot and denies positional advantage.

QJo is dominated by the SB's large 3-bet range (AQ/AK/QQ+), and I'd be out of position with the button still to act; I need ~29% equity to call and likely don't have it. Folding loses nothing beyond the sunk blind.

K7s is too weak and dominated to continue against a sizable small-blind 3-bet; calling or 4-bet bluffing is not profitable enough here.

A7o is a profitable standard open from the button in 3-handed play. Opening to 2.5bb to build the pot in position.

Pocket fours is a standard set-mine call against a small 2.5x raise; with ~9750 behind and 3:1 immediate odds, the implied odds justify seeing a flop rather than folding or 3-betting a marginal pair out of position.

Ad6s is playable at this price: 150 more into 600 is 4:1, and a suited ace has enough equity and flop potential multiway to continue rather than fold or squeeze out of position.

My 44 is third pair on a K-J-3 board with two clubs and two opponents who called a raise, so I have little value or fold equity. Checking keeps the pot small and lets me fold cheaply to aggression or re-evaluate on the turn.

Ace-high with no pair or draw on a king-jack flop, and the preflop raiser still to act. Checking is free and avoids bloating the pot with air.

In a three-way pot on a coordinated king-jack board, checking back allows us to realize our Ace-high showdown equity and backdoor potential for free.

My pair of fours is nearly worthless on a K-J-9 board with a club draw possible, and betting has little fold equity against two players who called a preflop raise. Checking is free and lets me fold cheaply if either opponent shows strength.

Ace-high with no pair and no draw has little value, and I can see the river for free. Checking keeps the pot small rather than bluffing into two opponents.

Holding Ace-high in position in a three-way pot on a wet board, taking a free card gives us a chance to hit an Ace or evaluate on the river.

Pocket 4s are weak on a J-K-9-7 board with no improvement; everyone checked, so check it down rather than bluff a multiway pot.

Ace-high has no pair or draw on this board, and two opponents remain. Checking is free and avoids bluffing into a range that often has a pair.

I paired my seven on the river with top kicker, giving me decent showdown value after everyone checked three streets. Checking behind realizes my equity without risking a raise.
