Hold'em table

6c7d is a playable suited-connector-style hand on the button 3-handed; a min-raise to 250 builds a pot with position while keeping risk low.

T6 offsuit is too weak to continue from the small blind against a button raise, especially with the big blind still to act. Folding avoids putting more chips in with a dominated, low-equity hand.

49 offsuit with a small raise to face; not worth calling from BB out of position against a button raise.

Pocket deuces are playable from the button in three-handed, so I open to 2.5bb to take the initiative and fold out weaker hands.

7-5 offsuit is weak facing a raise from the button; folding is cheap and preserves chips.

Queen-four suited has decent playability and I'm getting roughly 2.7:1 to defend my blind against a 2.5x button open. Calling keeps the pot small and preserves positional flexibility postflop.

I have bottom pair with a weak kicker on a K-high board; checking keeps the pot small and avoids building a big pot out of position against the preflop raiser.

Pocket deuces are an underpair on a king-high flop and fare poorly when called, so checking back keeps the pot small and realizes a cheap showdown.

I only hold bottom pair with a gutshot to the jack out of position against the preflop raiser; with zero to call, checking keeps the pot small and gives my draw a free card.

Pocket deuces is a weak pair on a king-high board, and seat_1 has shown no aggression. Checking keeps the pot small and realizes showdown value without turning my hand into a bluff.

Pair of deuces is too weak to value bet on this king-high, three-heart board, and a bluff is unlikely to fold out better hands after a passive line. Checking realizes the small showdown value.

As button in a 3-handed pot, T8o is a reasonable steal-raising hand; a standard 2.5x open applies pressure on both blinds.

95s is far too weak to call a 2.5x raise from the button while out of position; folding preserves chips for better spots.

K6 offsuit is too weak to continue out of position against a button open, so folding is the highest-EV option.

Q3o is marginal, but on the button in a 3-handed game a min-raise is cheap and has solid fold equity against two blinds; position makes it playable if called.

J8 offsuit is too weak to continue out of position against a button open; folding avoids a dominated spot with poor playability.

J4o offsuit is weak; facing a raise with a poor hand, folding is best.

ATo is a clear open from the button in three-handed play. A 3x raise builds the pot and applies pressure before the blinds act.

K8 offsuit facing a 3bb raise from the button is not worth defending from the small blind; folding is cheap here.

65o out of position against a button raise is too weak; even with 2.25:1 pot odds, equity realization is thin, so folding is the profitable line.

Q5 offsuit on the button facing a raise is a weak hand with poor equity; folding preserves chips.

Heads-up after the button folds, QTo has strong equity against the BB's range, so a standard 3x open builds the pot and applies pressure rather than limping into a dominated spot.

93 suited is too weak to continue against a 3bb open; it is dominated often and does not realize equity well enough to call 200.
