Hold'em table

Q8o on the button in a 3-handed game is a reasonable open-raise; stealing the blinds with position is profitable and a 2.5x open keeps it standard.

96 suited is too weak to continue out of position against a button open with the big blind still to act.

2c7c is a weak offsuit hand with a raise and call already in; not worth continuing from the big blind facing additional investment.

Button first-in with suited J6 in three-handed; a small open takes the initiative with position rather than flatting a weak offsuit-dominated hand.

2d7d is a weak offsuit hand facing a raise; folding from the small blind is standard here to avoid investing more with a poor holding.

9c6c suited one-gapper in the big blind facing a 2.5x button open with 150 to call into 400; getting ~2.7:1 closing the action, this is a standard defend with a playable suited hand.

Monotone diamond board with 9c6c gives me no flush draw, just a gutshot (7) and overcard-ish backdoor; checking to the preflop raiser is standard out of position and keeps the pot small.

I have the jack-high diamond flush on a monotone flop and the big blind checked, so I bet about three-quarters pot for value while leaving room for worse made hands and draws to continue.

Monotone diamond board with no diamond and only a weak gutshot to a 7 (one of which completes the flush); calling 400 into 950 is far too expensive for ~8% equity against a button c-bet.

K8 offsuit on the button is a reasonable raise-first-in hand against two players; raising to 300 applies pressure and builds a pot when I have position.

J5 offsuit in the small blind facing a 3x button open is a clear fold; out of position with a weak, dominated hand.

J6o is too weak to continue out of position against a button open; folding avoids a dominated, low-equity spot.

K5o on the button in a 3-handed game is a standard open; raising 2.5x applies pressure on the blinds and takes initiative with position.

57o is too weak to continue out of position against a button open, with the big blind still to act. Folding avoids putting more chips in with a dominated, poorly connected hand.

J8 offsuit is weak out of position against a raise; folding is standard here.

A5 suited is a strong button open in three-handed play, so I raise to 3x the big blind to take the initiative and fold out weaker hands.

J7 offsuit is weak against a 3x raise from the button; folding is the correct standard play from the small blind facing this action.

7-5 offsuit out of position against a button 3x open is a clear fold; poor playability and weak equity don't justify calling 200 into 450.

Weak offsuit low cards out of position relative to two players; not worth calling from the button with 54o facing a raise-limp scenario.

Button folded; K7o from the small blind heads-up vs the big blind is a standard raise (3x) to take initiative and often win the blinds outright.

94 suited is too weak to continue against a small-blind raise after the button folded; folding avoids a dominated, poorly connected hand.
