Hold'em table

Button raise with a suited king in a 3-handed spot to build the pot and take advantage of position.

Ace-ten offsuit is strong enough to 3-bet from the SB against a 2.5x button open, applying pressure and building a pot with position on the button postflop.

Jack-nine offsuit is too weak to continue against a button open and a small-blind three-bet to 800. Folding avoids putting more chips in with a dominated, unsuited hand out of position.

K5s is too weak to continue against a 3-bet reraise; folding preserves chips for better spots.

43o is one of the weakest hands and I'm out of position postflop even from the button in 3-handed play. Folding preserves chips for better spots.

T8o is too weak to continue out of position for a raise, and calling leaves a dominated hand against the big blind.

J6s is playable from the button in three-handed play with position, so I open to 2.5bb rather than limp or fold.

King-six offsuit is dominated by the button's 2.5x raising range and I'd be out of position postflop with a weak kicker; folding the 150 more is the cleanest play.

2-6 offsuit is a weak hand not worth playing from the button facing a raise.

Heads-up in the SB with an ace, I have decent equity and fold equity against only the BB; raising to 3x applies pressure and can win the pot immediately or build a pot with position.

Pocket queens is a clear value 3-bet heads-up against a small-blind open. Raising to 1000 builds the pot out of position while keeping their calling range wide enough to continue.

A2o is far too weak to continue against a 3-bet to 1000 out of position; calling 700 more with only ace-high and a dominated kicker has poor equity and reverse implied odds.

87s is a solid suited connector to attack from the button in 3-handed play; a standard 3x open puts pressure on the blinds and can win the pot or build a stack when I connect.

J9 offsuit is too weak to continue out of position against a button open, so I fold rather than call 250 more.

J6o offsuit is weak against a raise; folding is standard here.

K3o is too weak and dominated to open from the button even three-handed, so folding is the highest-EV option.

Cheap price to see a flop heads-up with reasonable pot odds, even though T6o is weak.

T9 offsuit in the big blind against a limper is a free flop; checking keeps the pot small with a speculative hand.

Weak gutshot draw with no pair; checking behind is cheap and keeps pot small while retaining outs to a 9.

I have an open-ended straight draw (any J or 6) on a coordinated board against a limper who checked; a small bet builds the pot with fold equity while keeping risk low.
