Hold'em table

Opening from the button with 54s to apply pressure and play a playable suited connector in position.

K2 offsuit is too weak to continue from the small blind against a button open, with the big blind still to act. Folding avoids putting more chips in with a dominated, unconnected hand.

J8 suited in the BB with only 100 to call into a 350 pot is a cheap, playable spot with position-equity; folding is too tight for the price.

The board pair of nines gives me showdown value, but my J8 kicker is weak against a preflop raiser who could hold trips or an overpair. Checking keeps the pot small and lets me reassess cheaply on later streets.

C-betting 1/3 pot on a dry, paired board where the preflop raiser has a substantial range advantage, while holding backdoor equity and a gutshot.

J8o has almost no equity on a paired 993 board against a preflop raiser who continued betting; calling 150 with jack-high is unprofitable.

Ace-nine suited is a strong button open in three-handed play, so I raise to 3bb to build the pot and take the initiative.

Ten-deuce offsuit is one of the worst starting hands, and facing a 3x open with the big blind still to act behind me, calling 250 into a small pot has no profitable line. Folding preserves chips for better spots.

Facing a 3bb open from the button, J9o plays poorly out of position and does not have sufficient equity to justify calling 200 chips.

Q5o is too weak to complete or raise from the small blind out of position.

Open-raising K8o on the button in 3-handed play to steal blinds and realize positional advantage.

24 suited is too weak to continue from the small blind against a button open, especially out of position with the big blind still to act.

K7s is a playable suited king on the button in three-handed, so I open to 3bb rather than limp or fold.

A8s is too strong to fold against a wide button open, and calling out of position with the big blind still to act invites squeezes. A 3-bet to 900 applies pressure and can isolate the opener.

QJo is heavily dominated against an open and a 3-bet from the blinds, so folding is clearly optimal.

K7s is too weak to continue against a 9bb small-blind 3-bet: it is often dominated and has poor equity and reverse implied odds even in position. Folding avoids putting more chips in with a hand that does not meet the required pot odds against a typical 3-bet range.

A7o is a standard button open in 3-handed play; raising to 3bb applies pressure on both blinds and builds the pot with position when called.

Facing a 3bb open from the button, small pairs like 44 play poorly out of position from the small blind with the big blind yet to act.

A6s has enough equity and suited playability to defend the big blind against a button open, getting a reasonable price to see a flop.

Ace-high with no pair or draw on K-J-3; checking is free and preserves showdown value against the preflop raiser.

As the preflop raiser in position on a K-high flop, a continuation bet of roughly half pot leverages my range advantage and fold equity; my ace-high plus backdoor club draw gives some backup if called.

Ace-high with no pair or draw on a K-J-x board is too weak to continue against the preflop raiser's flop bet.
