Hold'em table

J8 offsuit is a marginal hand out of position postflop against two players still to act behind me... actually on the button, but it plays poorly against blinds' ranges and calling 100 into 150 is roughly break-even at best; folding is a low-variance choice.

Q2o is too weak to play profitably out of position from the small blind against the big blind.

Opening with a premium hand (AKo) on the button to 2.5x for value and positional advantage.

Seven-five offsuit is too weak to call a button raise from the small blind with the big blind still to act.

QJo is a decent hand against a button open, and calling 150 more into a 400 pot gives about 2.7:1 odds. Closing the action from the big blind makes a call better than a bloated 3-bet with a hand that plays poorly when dominated.

Heads-up in position disadvantage on a K-8-6 two-spade flop, I hold a backdoor straight draw, a backdoor flush draw and two overcards to the 8 and 6 (Q-J with a K on board gives a gutshot-ish, actually an open backdoor). A modest bet of about 64% pot builds the pot with equity and denies equity from the button's wider range; the sizing keeps risk small. .

Holding top pair top kicker in position against a donk bet, calling keeps their bluffing and drawing range wide while keeping the pot manageable.

Queen-high with a gutshot and a backdoor flush draw on a paired board; I already bet the flop and was called, so I'll check to control the pot and see the river cheaply.

I have top pair top kicker on a paired board with straight and flush draws present. Betting for value and protection against draws and weaker Kings after the opponent checked.

Queen-high with a gutshot-type draw (needs a ten for the straight) and only two overcard outs is weak here. I have 700 to call into a pot of 1950, which requires about 26% equity. The opponent's button raise after my check likely represents a strong range, so I'd be a clear underdog.

Nine-five suited is playable from the button in a three-handed game. A 2.5 BB raise gives me a chance to take the blinds or play in position.

2c8c is a weak offsuit-ish hand out of position in the small blind facing a button raise with the big blind still to act, so folding is best.

Holding 83s out of position against a button raise is too weak to defend profitably, so folding is standard.

5-4 offsuit is a weak hand, and calling from the button out of position against two players has poor value, so I'll fold and wait for a better spot.

Folding 43o from the small blind as it is too weak to play out of position.

On the button in 3-handed play, K7o is well within a standard opening range, so I enter with a standard min-raise.

Nine-six offsuit is too weak to defend from the small blind against a button raise with the big blind still to act.

A3o in the big blind facing a button min-raise gets a good price: 100 to call into a 350 pot. The hand has an ace and position is against me, so calling is better than folding or bluffing a 3-bet.

Top pair with a good kicker and a wheel draw on a dry-ish but draw-possible flop. I'm first to act heads-up against the button's preflop raise, so I bet about 2/3 pot for value and to protect against overcards and flush draws.

I hold King-high with virtually no equity on an Ace-high board facing a donk bet, making this an easy fold.

A8 offsuit is strong enough to open on the button three-handed. A 2.5 big blind raise pressures the blinds while keeping the pot manageable.

K3 suited from the small blind facing a button open and a big blind still to act is weak and often dominated, so folding is the disciplined choice over calling 200 more out of position in a three-way pot.

K7o performs poorly out of position facing a 2.5x open from the button, making it a clear fold.
