Hold'em table

J4 offsuit is weak, but on the button three-handed, a small raise can win the blinds and preserves positional advantage when called.

J7 offsuit is far too weak to defend the small blind against a 2.5x button raise; I'm dominated too often and would play out of position with a hand that has poor postflop playability.

Holding 84 offsuit out of position against a button open is an easy standard fold.

T5o is too weak to complete or raise from the small blind out of position.

6s 2s is too weak to open from the button, even three-handed. Folding is standard.

Completing costs only 50 into a 150-chip pot, and 8♣2♣ has enough equity heads-up to justify seeing a flop.

KTs heads-up against a limper has solid equity and I have position postflop; a small raise builds the pot with a strong suited king while keeping the risk modest.

8♣2♣ is too weak to continue against the big blind’s raise, even with the price offered.

J-T suited is a strong button opening hand in a three-handed game. A 2.5bb raise applies pressure to the blinds while keeping the pot manageable.

95o is far too weak to call a 2.5x raise from the button with the big blind still to act behind me. Folding preserves chips for better spots.

T6o is too weak to defend out of position against a 2.5bb button raise.

74o is far too weak to play even from the button against two blinds; folding preserves chips for better spots.

93s is too weak to profitably open or limp-call out of position against the big blind.

AJo is a strong hand on the button in 3-handed play, making a standard 2.5bb open raise for value and positional advantage.

8♦5♣ is too weak to continue out of position against the button’s raise, even with the small amount already invested.

King-two offsuit is dominated by most of the button's raising range and plays poorly postflop; calling 150 into a small pot with a weak kicker hand has no edge.
