Hold'em table

AT offsuit is a solid button raising hand heads-up-ish against two blinds; a standard 3x open builds the pot with a strong holding.

With 5-3 offsuit (one of the weakest hands in poker) against a button raise, folding is the mathematically sound play. Even though I'm only closing 250 chips to call, the hand has poor equity and no real prospects.

K6 offsuit has sufficient equity to defend the big blind against a button open, particularly heads-up after the small blind folds. Calling keeps the pot manageable while retaining playable king-high coverage.

With only king-high and a weak heart draw, checking keeps the pot controlled and retains some showdown value against missed overcards.

As preflop raiser I'll continuation bet on this dry board with A-high, aiming to pick up the pot from a checking big blind.

K-high with only a weak backdoor heart draw has insufficient equity versus the continuation bet.

With 3-2 offsuit in the small blind facing the big blind, completing is unprofitable.

On the button, Kd2h is a reasonable steal candidate against the blinds. Raising gives initiative and can win the blinds immediately.

Q2o is a weak hand in a 3-handed game facing a raise to 250 chips (150 to call). The raiser from the button is likely strong, and my hand is dominated in most matchups. Folding preserves chips for better opportunities.

Weak offsuit-ish low connector (3d5d suited actually) but on button facing raise not yet, still low value hand to call from button in 3-handed vs blinds; fold to preserve chips.

AK is a premium hand. With seat_1 folded and only the big blind to act, raising to 300 chips (3x BB) is a strong play to build the pot and take control of the hand.

A5 suited is a strong heads-up blind-versus-blind candidate to 3-bet, with an ace blocker and robust equity when called. Raising applies pressure to a wide small-blind opening range.

AK is a premium hand that wins significantly against most ranges. Seat_3's 3.3x raise suggests strength, but we have one of the strongest non-pair holdings. Going all-in maximizes our expectation and avoids difficult postflop situations where our hand loses equity. With 100bb effective stacks, this is a standard GTO move that builds our chip stack when successful.

Calling with A5 suited is justified by the pot odds: 9,000 to win 11,000, and an ace has substantial equity against a likely broad shoving range.

4d-Ks is a weak hand in a 3-player game where action is on me and I'd need to call 100 chips into a 150-chip pot with poor equity. Folding preserves chips and avoids a marginal situation.

A suited ace is well ahead of the big blind's likely checking range heads-up. Raising to 3bb builds value while retaining maneuverability.

KQo is strong heads-up against a single opener; 3-betting builds the pot and pressures a wide SB range.

Ah8h is a suited ace with good playability, and calling the 3-bet keeps the pot manageable while receiving favorable pot odds.

I have top pair with the best kicker in a heads-up 3-bet pot. A moderate continuation bet extracts value from worse pairs and denies equity to overcards.

9-high offsuit with a weak kicker is a poor button opening hand in this structure; folding avoids marginal reverse-implied-odds spots.

KJ suited is a strong hand heads-up against the big blind after the button folded, so I raise to isolate and build the pot.

K6o is a weak hand that doesn't warrant calling a raise from an early position raiser. With only 100bb stack depth and marginal holdings, folding here preserves chips for better spots.
