Hold'em table

K5o is too weak to profitably open from the button in 3-handed play.

A6o on the button in a 3-handed game is a standard open-raise; the ace has blocker value and position lets me take the pot with pressure or postflop aggression.

KJo is ahead of a wide button open in three-handed play, so a small three-bet takes the initiative and folds out dominated hands.

Folding 85o facing an open and a 3-bet.

A6o is dominated by most 3-betting ranges and needs about 32% equity to call 550 into 1150, which it lacks against a value-heavy range. It's at the bottom of my continuing range, so folding is the disciplined play.

T6o is too weak to open from the button for a full raise, and calling leaves me dominated too often. Folding preserves the stack for better spots.

In a blind-vs-blind spot after the button folds, Q9o is strong enough to open-raise for value and pressure against the big blind.

9s6d offsuit is far too weak to defend against a 3x raise even getting a good price heads-up; folding avoids playing a dominated hand out of position.

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

Ace-high in the small blind heads-up is too strong to fold; raising to 300 pressures the BB and can win the pot immediately.

Q9o is too weak to continue against a 3bb small-blind raise; it is easily dominated and does not realize equity well enough to justify calling.

Queen-eight offsuit on the button is a decent stealing spot; a small raise builds pressure and folds out weak hands while retaining fold equity.

98o is too weak to call a button 3bb open with the big blind still to act, and a light 3-bet is not worth the risk.

Holding 62 offsuit in the big blind against a 3bb open is an easy fold with virtually zero playability or equity.

Three-handed on the button, K5 suited is a standard open: it has king-high equity, suited playability, and position. A 2.5bb raise builds the pot and can take it down preflop.

T6s is too weak to continue from the small blind against a button open with the big blind left to act.

Seven-three suited is far too weak to defend against a button open while out of position; folding avoids playing a dominated, hard-to-realize hand.
