96o is too weak to open from the button even in 3-handed play.

Ace-x suited-ish A4o is a decent hand heads-up against the big blind after the button folded; raising in the small blind builds the pot with initiative and fold equity. A 3x raise is a standard size.}

J♥T♥ plays well in position against a small-blind open, so calling keeps weaker hands in while limiting preflop risk.

Top pair with ace and a backdoor wheel draw on a flop with a flush draw possible; bet about 2/3 pot for value and protection against spade draws.

J-high has no pair or immediate draw on this ace-high flop. Calling the 400-chip bet is unlikely to be profitable.

Q2 offsuit is a weak hand, and as the button in a 3-handed game I would be out of position postflop against two opponents, so folding is better than calling 100 with it.

JTo is strong enough to raise heads-up against the big blind, seeking value and fold equity despite being out of position.

Holding AJs in position against a small blind open, a 3-bet to 10bb builds value against a wide range and takes initiative.

JTo is often dominated by a big-blind three-bet range, and calling 700 more out of position is unlikely to be profitable.

Q2 offsuit is too weak to open profitably from the button against two unknown opponents.

Folded to the small blind; raising JTo to 300 to attack the big blind with good connectivity and high card value.

K8 suited is a decent hand in the big blind facing a 3x small blind open in a 3-handed game, and the pot odds (200 to win 500) are good enough to defend by calling rather than bloating the pot out of position.

As the preflop aggressor on an Ace-high board that favors my opening range, a small one-third pot continuation bet applies pressure with good backdoor equity.

Kd8d on 9c4cAs has a backdoor diamond draw and some showdown value with king high. A 200 bet into 600 is a small continuation bet, so calling is cheap. Raising would mostly fold out worse hands and get called or raised by better ones.

Holding jack-high with minimal equity after being called on the flop, checking gives up the bluff lead without risking further chips.

Board is 9c 4c As 4d and I hold only king-high with a backdoor-less diamond. The opponent bet the flop and then checked the turn, so I have modest showdown value. Checking keeps the pot small and avoids getting raised off a hand that might be best.

I have Jack-high with zero showdown value, even losing to villain's missed high-card draws. Having uncapped range advantage with Aces in my line, a river bet can fold out weak pairs and superior missed draws.

Getting about 3.5-to-1 (need roughly 28% equity). King-high beats all of villain's missed draws and air, and a wide SB raising range that checked the turn has enough bluffs to make this a marginal bluff-catch.

75o is too weak to open profitably even on the button in 3-handed play, so folding is standard.

J6o in the small blind heads-up against the big blind, with the button already folded. Completing costs only 50 more into a 150 pot, which is a good price, so I call rather than fold or make a marginal raise.

Q5 offsuit is marginal against a small-blind limp. Checking takes a free flop and keeps the pot manageable while playing in position.

I have only jack-high with a backdoor draw on a K-Q-4 board, so I have no value to bet. Checking is safe and keeps the pot small against the big blind's range, which is uncapped after a limp.

Middle pair can get value from weaker pairs and draws. A modest bet also protects against the flush and straight draws on this board.

6c Js on a 4h Kd Qd board has only a gutshot draw (needs a 10 for the straight, with A also making a straight? A-K-Q-J needs 10). Calling 120 into a pot of 320 needs about 27% equity, and a gutshot plus a possible overcard-free bluff line is short of that, so folding is the disciplined choice.

4d7d is a weak offsuit-ish hand from the button facing the big blind in a 3-handed game; it is marginal, but folding avoids a costly out-of-position postflop spot against two opponents yet to act behind me is not an issue. Folding is the low-variance choice.

Ace-deuce offsuit is strong enough to raise heads-up against the big blind, even from out of position. A 2.5-big-blind raise pressures the blind without building an oversized pot.

Folding 64o facing a small blind open as it has low playability and equity.

Eight-three offsuit is too weak to profitably open on the button against two unknown blinds.

42o is far too weak to defend out of position even blind vs blind.
