Hold'em table

2h3s is too weak to call or raise from the button in a 3-handed preflop spot, especially with no reads.

King-Ten suited is a reasonable hand in position on the button. Raising preflop applies pressure, allows us to take down the pot immediately or play the rest of the hand in position with initiative. A 3bb raise is standard.

9c4c is a weak, dominated small-blind holding facing a button open, and calling would play poorly out of position.

5-7 offsuit is too weak to defend out of position against a button raise, so folding preserves chips.

Button A4 suited with an ace blocker is a reasonable opening hand three-handed. I raise to apply pressure and retain initiative.

K2o is too weak to continue out of position against a button raise, especially with the big blind still to act. Folding avoids playing a dominated hand.

5-Jack offsuit is a weak hand in early position against a raise. With seat_3 having raised to 250 and needing to call 150 more, folding preserves chips for better opportunities.

A8o is strong enough to open-raise on the button in a 3-handed game, applying pressure on the blinds and taking initiative.

7-3 offsuit is the worst hand in poker. Facing a raise to 300 from button with big blind still behind, folding is the clear play. Preserving chips for better spots is optimal strategy.

9-5 offsuit is too weak to defend against a button 3x open from the big blind without stronger evidence of excessive opening.

T5o is a weak hand in early position against two opponents. With a to_call of 100 chips, folding preserves chips for stronger opportunities and avoids playing a marginal hand out of position.

Complete the small blind with a playable connected hand and realize equity heads-up at a minimal price.

The button folded and the small blind limped, so A3o has enough equity and fold equity to raise for value and initiative. A raise to 300 pressures the limper without committing too much with a marginal offsuit ace.

9-high offsuit is too weak to continue out of position against the big blind's isolation raise.

Q6 offsuit is a weak button holding and not worth entering with at this stack depth.

Button folded, so this is a heads-up battle where 45s has decent equity and fold equity. Raising to 300 applies pressure and builds the pot when called.

8c7c is a weak holding facing a 3x raise from the small blind, and I'm out of position as the big blind. With only two players remaining and strong preflop pressure, folding preserves chips in an unfavorable spot.
