Hold'em table

Suited ace on the button is a clear open; a 3x raise builds the pot and applies pressure before the blinds.

Ace-king suited is a premium hand from the small blind; a sizeable 3-bet builds the pot and puts pressure on the button while discouraging the big blind from coming along.

Folding Q6o facing an open and a 3-bet.

A5s is too often dominated by a large small-blind 3-bet, and the price does not justify continuing out of position equity-wise.

7-2 offsuit is an especially weak starting hand, so I fold rather than invest chips from the button.

Holding 85s out of position against the big blind is marginal; folding avoids difficult postflop spots with a weak suited connector.

J3s is too weak to profitably open even from the button in 3-handed play.

28o is too weak to complete or raise out of position against the big blind after the button folds, so folding the extra 50 is the lower-variance choice.

Jack-ten offsuit is a solid button open in three-handed play, so I raise to 2.5 big blinds to take the initiative and fold out weak hands.

9♠6♣ is too weak and poorly suited to defend the small blind against a button raise, especially with the big blind still to act.

J8o is too weak to defend out of position against a 2.5bb button open.

A3 offsuit is a profitable button open in a three-handed game. Raising applies pressure to the blinds while keeping the sizing modest.

Q6s is too weak to defend out of position against a button raise with the big blind still to act.

54s has enough equity and playability versus a button open to call 1.5bb from the big blind rather than fold or inflate the pot out of position.

5-4 missed this A-Q-8 flop completely with no pair or draw, so checking is the only sensible option against the preflop raiser.

I have top pair and can get value from weaker pairs while charging draws. A small bet keeps worse hands in and limits risk with my weak kicker.

54s completely missed Ah-8c-Qs with no pair, draw, or meaningful equity against a flop c-bet, so calling 180 is unprofitable.

Q8o is slightly too weak to open profitably from the button even in 3-handed play, so folding is the disciplined choice.

64o is too weak to continue out of position for a raise or a call against the big blind.
