Hold'em table

7-5 offsuit from the button facing a full BB price is a clear fold; it has little equity and poor playability 3-handed. No reason to invest 100 chips with trash.

AKs is a premium hand heads-up versus the big blind after the button folded, so I raise to 3bb to build the pot and take the initiative.

Holding 73 offsuit facing an open raise from the small blind is an easy fold despite getting pot odds.

T8 suited is a playable button open in a three-handed game, so I raise to 2.5bb to steal the blinds and build a pot with a suited connector.

A3 offsuit plays poorly out of position against a button raise with the big blind yet to act, making fold the standard play.

4-6 offsuit is nearly the worst hand in the deck, and I'd be out of position against a button raise. Calling 150 into a small pot with no postflop playability is -EV, and a 3-bet bluff with no blockers is too thin, so folding is clearly best.

J7 offsuit is too weak to open profitably from the button even in 3-handed play.

Button folded, leaving a heads-up pot where 78o has solid equity plus fold equity; a standard 3x open takes initiative, and I can still fold cheaply if the big blind plays back aggressively.

3-5 offsuit is too weak to continue against a raise, even from the small blind after the button folded. Folding avoids putting more chips in with a hand that rarely flops well.

On the button in a 3-handed game, 79o is a standard wide open; a min-raise builds the pot with position and applies pressure to both blinds.

72 offsuit is too weak to continue against a button open, especially out of position for 150 more.

T7o is too weak and disconnected to defend profitably out of position, even against a min-raise.

KQs is a premium suited hand on the button, so I open to 3bb to build the pot and take the initiative rather than just calling.

Pocket threes out of position facing a 3x open with the big blind still to act is unprofitable to set-mine, making fold the standard play.

Q6 offsuit is far too weak to defend the big blind against a 3x button raise; the dominated, poor-playability hand doesn't justify calling 200 into 450 despite the loose pot odds.

Opening King-Eight suited on the button is standard in 3-handed play to steal blinds and realize positional advantage.

5h7d is a weak hand facing a 2.25x raise from the button with a player still behind; folding avoids investing more with poor equity.

J6o is too weak and easily dominated to defend out of position against a button raise, so folding is the disciplined play.
