Hold'em table

On the button in 3-handed play, 9-7 offsuit is within a wide opening range and plays well in position, so raising is better than limping or folding.

K5o is a weak offsuit hand out of position against a button raise, and calling 200 more would leave me dominated too often. Folding preserves chips with minimal loss.

63o is a weak offsuit hand with poor equity and no position advantage worth defending; folding to the 100 call avoids playing a dominated, low-potential hand out of position.

Q-3 offsuit is a weak hand from the small blind. After seat_2 folds, I need to call 50 more chips to face the big blind. With a mediocre holding against one opponent, folding minimizes expected losses.

Ace-high with position on the button is a solid hand. Raising 3.5x the big blind applies pressure, controls the pot, and leverages positional advantage. This isolates weaker hands and builds a lead in the hand.

4-2 offsuit is one of the weakest hands and facing a 3.5bb button raise from the small blind, calling out of position is unprofitable.

Kd8d is a reasonable hand to defend the big blind against a button open; calling 250 more closes the action with good pot odds and keeps the pot manageable out of position.

I have middle pair with a king kicker on an ace-high flop and am first to act; checking controls the pot and avoids bloating it against the preflop raiser's stronger ace holdings.

I have Ah6s on a flop of 2d-As-8c, giving me top pair with a weak kicker. Seat 2 checked, indicating weakness or a drawing hand. Checking allows me to see the turn safely while controlling pot size against a likely weaker holding, as my raise preflop likely eliminated most of seat 2's premium hands.

I have middle pair plus a flush draw, so betting the turn builds value and protects my equity. If raised, I can reevaluate given the strong draw.

I have A6 which is a weak holding on a coordinated board (2-A-8-J). Seat 2's aggressive turn raise suggests strength, and calling puts me in a difficult river spot. Folding preserves chips against a likely stronger hand.

K5o on the button in 3-handed play is strong enough to open; raising pressures the blinds and takes initiative rather than limping or folding.

A9o is strong enough against a wide button open, and a 3-bet puts pressure on the big blind while taking initiative. I can fold to further aggression and avoid playing a marginal hand passively out of position.

With T-Q of clubs (a weak holding), facing a reraise to 800 and a minimum raise requirement of 1350, the risk-reward is poor. The aggression from seat_2 suggests a strong hand, and my stack is best preserved by folding here.

K5o is weak and dominated against a small-blind 3-bet to 800; calling 550 needs more equity than this hand has versus that strong range.

With 4d8c on the button facing a full big-blind call, this is a weak offsuit hand with poor playability and no pot odds incentive to continue in a 3-handed preflop spot.

4-8o is a weak hand in a 3-way pot with only 50 chips to call but significant equity disadvantage. Folding the small blind is optimal against a big blind raise when holding this weak unprofitable holding.

8-4 offsuit is a weak hand in poker. From the button, folding marginal hands is standard strategy, especially when facing a big blind raise. Preserving chips for better opportunities is more valuable than playing a dominated hand.

A8o is well ahead of a big blind's random range heads-up after the button folded, so raise for value and to take initiative.

AQo is a strong heads-up hand against a small-blind open, and raising for value takes initiative while I retain postflop position as the big blind.

A8o is dominated by a big blind 3-bet range and will play poorly out of position, so calling 600 does not realize enough equity despite the pot odds.
