Hold'em table

On the button, J7 suited has reasonable playability and benefits from applying pressure to the blinds. A small open keeps the risk controlled.

2-7 offsuit is the worst starting hand; facing a 2.5x raise, folding is clearly correct.

73 offsuit is too weak to continue out of position against a button open, so folding is the highest-EV line.

J7o is a weak offsuit hand out of position postflop; folding to the BB is standard.

Button folded, so this is heads-up versus the big blind. Suited 69 has enough playability to raise for initiative rather than flat and play out of position.

T5 suited is too weak to defend profitably against a small-blind raise when heads-up out of position.

75 offsuit is too weak to call or raise from the button for 1bb, so folding preserves chips.

With a middle pair heads-up against the big blind after the button folds, I raise for value and to deny overcard equity.

Q3o is far too weak to call a 3x raise out of position; folding is clearly best.

Q8 offsuit is strong enough to open from the button three-handed. A 2.5bb raise applies pressure while retaining maneuverability.

5-3 offsuit is a weak hand facing a 2.5x raise with a player still to act; folding is clearly best.

74 suited is too weak to defend out of position against a button raise; calling would realize poorly and folding preserves chips.

5-6 offsuit from the button is too weak to play multiway; folding is the standard profitable line.

9-3 offsuit is too weak to complete the small blind heads-up against the big blind, so folding saves the extra half-blind.

Q6 suited is playable as a button open in three-handed poker; a small raise takes the initiative and can fold out worse hands.

K7 offsuit is too weak to defend from the small blind against a button open with the big blind still behind.

T4o is a weak hand facing a 2.5x raise out of position; folding is clearly best.
