Hold'em table

Q8o on the button in a 3-handed game is a standard open; raising builds fold equity and lets me play the hand in position with a decent holding.

A3o plays poorly out of position against a button open, making an easy fold from the small blind.

6-2 offsuit is too weak to continue against a button open; folding saves chips.

T3o is far too weak to open from the button even 3-handed. Folding is standard.

AQo is well ahead of the big blind's range after the button folds, so I raise rather than complete. A raise to 300 builds the pot while keeping the big blind's calling range wide.

75 offsuit is dominated frequently and plays poorly out of position against a 3x raise; the 33% pot odds needed don't compensate for bad postflop realization with this hand.

A3s is well within a 3-handed button open. Raising to 3bb takes the initiative and builds the pot with suited-ace equity rather than flat-calling.

Q9 offsuit is dominated by the button's 3x opening range and I'm out of position with two players left to act, so folding is clearly best.

97 offsuit is too weak to defend out of position against a 3x button open. Folding is standard.

On the button three-handed, K2o is near the bottom of a viable opening range but still worth a min-raise: I have position on both blinds and can win many pots cheaply or play postflop with an edge. Folding is too tight at this price.

Pocket eights are well ahead of the button's wide opening range in 3-handed play; 3-betting to 7.5bb builds the pot and denies equity from out of position.

A2o is too weak to continue against a button open and a small-blind three-bet; folding avoids a dominated, poorly playable spot.

K2o is a weak hand facing a 3-bet after I opened; calling out of position with kicker problems is unprofitable, so folding preserves chips.

Opening from the button with Ten-Nine suited is a standard profitable open raise.

5-2 suited is too weak to continue against a button open from the small blind, with the big blind still to act. Folding avoids paying 200 into a dominated spot.

K9 offsuit is a standard big-blind defend against a 2.5x button open in a 3-handed game; calling 150 into a 400 pot offers good odds while keeping the pot small with a marginal hand out of position.

King-high on a paired low board with no draw; checking keeps the pot small and avoids bloating against the preflop raiser.

Check back with two overcards, a gutshot straight draw, and backdoor flush potential to realize equity in position without risking a check-raise.

Turn ace misses my K-high, but a bet here would rarely fold a preflop raiser. Checking keeps the pot small and lets me re-evaluate on the river.

The Ace on the turn heavily favors my preflop raising range, and after the big blind checks twice, a delayed c-bet can fold out weak pairs and unpaired hands.

King-high with no pair on a paired, ace-high board facing a turn bet; my hand has almost no equity against a value range.

JTs is a strong suited connector on the button, so I open-raise to 2.5bb to build the pot with position rather than flat the big blind.

Q2 offsuit is badly dominated against a button raise; calling 200 more into a small pot with a weak kicker has no profitable line even with positional disadvantage postflop.

K2o is too weak to defend out of position against a 2.5bb button raise despite getting decent pot odds.
