Hold'em table

Ace-ten offsuit is strong enough to open on the button. A 2.5 big-blind raise applies pressure while keeping the pot manageable.

5c 3h is an unplayable offsuit hand out of position facing a button open.

K6o in the big blind gets a good price: 150 to call into a 400 pot, about 27% equity needed. The button's 2.5x open is wide in 3-handed play, so calling is reasonable and a 3-bet bluff isn't needed.

King-high with a backdoor-free board is a weak hand out of position against the button's raise. Checking keeps the pot small and lets me see what the button does, and I may catch a bluff or pick up outs later.

A small continuation bet can win the pot against missed big-blind hands while keeping the risk modest with ace-high.

Ks 6h on a 7h Js 2h board has only king-high with a backdoor at best, and it faces a 180 bet into 550. Calling needs about 25% equity, which this hand is unlikely to have against a button c-bet range, and I have no clear plan on later streets, so I fold.

87 suited on the button 3-handed is a clear standard opening raise to build pot and take initiative in position.

2-3 offsuit is the worst kind of hand; calling 200 more out of position against a button raise with a big blind still to act is a losing play, so I fold.

A-Q offsuit is strong against a button opening range, and a sizeable three-bet puts pressure on the opener while compensating for being out of position.

Holding 87s in position against a standard BB 3-bet offers sufficient implied odds and playability to call 750 chips.

Top pair with a strong kicker is ahead of many hands that call a three-bet. A small flop bet gets value while charging club draws.

I only have a gutshot on a high, connected board against a preflop 3-bettor's c-bet, with insufficient pot odds to continue.

K2 offsuit is weak, and it plays poorly out of position against two opponents even from the button. Folding avoids a marginal spot at a cost of 0.

Pocket fours are strong enough to raise heads-up against the big blind. A modest raise can win the blinds or build a pot when called.

Q2o is too weak to profitably defend against a SB open, so folding is standard.

Five-three suited is a reasonable button open three-handed. A 2.5-big-blind raise uses position while keeping the pot manageable.

Holding premium AKo in the small blind facing a button open, standard play is a 3-bet for value and initiative out of position.

A5s is not strong enough to call 900 more facing a button open and a small blind 3-bet, with the button still to act behind me. Folding avoids a marginal, out-of-position spot.

Five-three suited is too weak to continue against a large three-bet, even with position.

K4o is too weak to open profitably from the button even in 3-handed play.

A8 suited is a strong hand heads-up from the small blind against a big blind, so raising for value and initiative is better than just calling.

KQo is strong against a small-blind opening range, and a three-bet builds the pot while I have position postflop.

A3-bet to 10bb from the big blind over my small blind open is strong. A8s is dominated by the hands that would continue, and calling 700 out of position with a 4-bet as the alternative is marginal. Folding is the safe choice.

3h9s offsuit is a weak hand and plays poorly out of position against two opponents, so I fold rather than pay 100 to call.

KJ suited is a strong heads-up hand against the big blind, so I raise for value rather than limp.

K6o is at the bottom of the defending range against a 3x open from the small blind, so folding is the standard, discipline play.
