Hold'em table

75o is too weak to open raise or call from the button, even 3-handed.

AK suited is a premium hand and seat_1 folded, so I raise for value and initiative from the SB rather than calling and playing out of position.

73 offsuit is far too weak to continue against a raise, even heads-up from the big blind. Folding saves the remaining stack for better spots.

T8s is a solid positional open on the button three-handed; raising to 3x builds the pot with position and applies pressure on the blinds.

A3o is too weak to continue out of position against a button raise, especially with the big blind still to act. Folding avoids a dominated ace and a poor postflop spot.

Holding 6-4 offsuit in the big blind against a button open, folding is standard due to low playability out of position.

J7o is too weak and poorly connected to open or limp from the button, so folding preserves chips.

Completing from the small blind with a connected offsuit holding getting 3-to-1 pot odds.

32o is junk, but heads-up with position I can apply pressure cheaply; a min-raise build folds out weak hands and lets me take the pot with a c-bet. A small iso-raise risks little against a limper.

Folding 87 offsuit out of position facing a 4x raise from the big blind.

97 offsuit is too weak to profitably open-raise from the button in 3-handed play.

7c2h is the worst starting hand in hold'em, and I'm out of position against the big blind with only a half-bet invested. Folding minimizes losses rather than chasing a flop with almost no equity or playability.

KQ suited is a premium hand in 3-max, and I have position on both blinds. A standard 3x open builds the pot with a hand that plays well postflop and puts pressure on the blinds.

Pocket threes are too strong to fold to a 3x button open at 100bb, and calling keeps the hand multiway for set-mining implied odds rather than bloating the pot out of position.

Q6o is too weak to defend out of position against a button raise and a small blind call.

Pocket threes are an underpair on a connected three-diamond flop, so I have little fold equity and poor equity if called. Checking keeps the pot small and preserves the option to fold to aggression.

KQ with no diamond on a three-diamond flop leaves me with little but a gutshot and overcards; checking back in position keeps the pot small and avoids getting blown off my equity by a check-raise.

Pocket threes have no diamond on a four-flush board, so a bet is unlikely to be called by worse and often gets raised by a flush. Checking is free and keeps the pot small.

I have king-high with no draw on a four-diamond board; betting would be a pure bluff with little fold equity after passiveness all around. Checking keeps the pot small and cheap.

Pocket threes with no diamond is only a weak pair on a four-flush river. Betting for value is hopeless and a bluff gets called by any diamond, so I check and try to win at showdown.

I hold no diamond on a four-diamond board, so my king-high likely loses to any bet; checking realizes no further loss and a bluff has little fold equity.

K8 suited is a playable button open in three-handed poker, so I raise to 3bb to take the initiative and fold out weaker hands.

75 offsuit is too weak to continue from the small blind against a button open raise.

J6o is weak against a 3x open from the button with the small blind already folded; calling 200 more to play a dominated hand out of position has poor EV.
