Hold'em table

On the button three-handed, a cheap min-raise with king-high pressures the blinds and lets me play in position; I can release cheaply if I face resistance or miss the flop.

ATs is a premium hand 3-handed. 3-betting to 900 out of position puts maximum pressure on the button min-raise and isolates effectively.

5♦4♥ is a weak offsuit hand, and facing a 9bb 3-bet the call is too costly without enough equity or playability.

K4o is dominated by virtually any hand that 3-bets to 900 after my open, and calling 700 more to chase a weak king with no draws is unprofitable even in position. Folding preserves chips for better spots.

T7o is too weak to open profitably from the button even in 3-handed play.

T9 offsuit is a playable blind-versus-blind hand, and a modest raise can take the pot down while building initiative. I choose a smaller sizing to limit risk out of position.

32 offsuit is the worst hand in hold'em and I'm facing a raise out of position; calling 150 more to chase a weak hand has no profitable expectation. Folding preserves chips.

7♠2♣ offsuit is too weak to continue profitably, even on the button facing only the blinds.

Ace-high offsuit on the button in a 3-handed game is a standard open; raising builds the pot with position and folds out weaker hands.

Folding 84s from the small blind against a button open, as it lacks sufficient playability and value out of position.

KTo is strong enough to defend the big blind against a button open, and calling keeps weaker hands in while avoiding an unnecessary large pot out of position.

I have a strong king-high flush draw, but checking out of position lets the preflop raiser act and keeps the pot manageable if they have a made hand.

I have the king-high flush, currently ahead of any opponent flush, and should value-bet while charging hands with a heart. A moderate bet can get calls without bloating the pot excessively on a four-heart board.

Opening from the button with J9o in 3-handed play to apply pressure and leverage position.

8-6 offsuit is too weak to defend out of position against a button raise, especially with the big blind still to act.

Seven-four offsuit is far too weak to defend the big blind against a button raise while out of position, even at the cheap price of 100 more chips.

As the button in a three-handed game, 9-8 offsuit is a reasonable opening hand. I raise to apply pressure and take initiative.

2d9s is a very weak hand out of position facing a 2.5x raise; folding avoids losing more chips with minimal equity.

K7o is too weak to defend out of position against a 2.5bb button open.
