Hold'em table

Q4o is too weak to open from the button in a 3-handed no-ante game; folding avoids putting chips in with a marginal hand.

Q-5o is a weak hand in 3-way play, especially out of position as the small blind. Folding avoids committing more chips with a marginal holding against two opponents.

3-8 offsuit is a weak hand in early position. With 100 chips to call and a small blind already in the pot, folding preserves my stack for stronger holdings. This hand is unlikely to win against competent opponents.

Heads-up versus the big blind, Q7s is strong enough to raise for initiative and seize the pot preflop; min-raising gives us a chance to win immediately and position postflop if called.

Holding 72o, one of the worst starting hands, facing a raise from SB, it's best to fold and wait for a better spot.

Three-handed on the button, K3o is weak but has enough steal equity against two blinds to open for 3bb and take initiative in position. Folding is too tight here, while calling invites the blinds in cheaply with a dominated hand.

8h4h is too weak to call or raise from the small blind out of position.

Holding pocket jacks (JJ) is a strong premium hand. Seat 3 raised to 300 from the button after seat 1 folded. A substantial 3-bet to 1000 applies pressure, builds the pot when ahead, and defines hand strength while remaining in control of the hand.

K3o is too weak to continue against a large 3-bet from the big blind, especially with the small blind already folded and poor playability postflop.

Q8o is a weak hand and I'm first to act preflop. With no reads, it's better to fold and preserve my stack for stronger opportunities.

T4o is a weak hand in the small blind facing a big blind bet. With no favorable odds or position advantage, folding is the mathematically sound decision to preserve chips.

K4o is a weak hand in early position (button with blinds to act). Folding minimizes losses against two opponents who have already committed chips, as this hand has poor win equity and no strong implied odds.

Getting 3:1 pot odds with 53o, calling is marginally profitable despite poor position.

With 9s8h, a reasonable three-bet size in a heads-up pot after a small blind limp can steal the pot preflop or build value on favorable flops.

With 5d3c out of position facing a raise, folding is best; the hand has poor equity and calling 200 more would be speculative.

T2o on the button is a weak offsuit hand with poor playability; folding to the big blind's raise avoids investing 100 chips out of position with a dominated hand.

Ah8s is a strong hand heads-up against the big blind; raising to 300 puts pressure and builds a pot with a decent equity hand while potentially taking down the dead money.

6-2o is one of the weakest hands in poker. Against a raise to 300 from the small blind, folding is correct even though I only need to call 200 more. The hand has minimal equity and poor playability postflop.
