Hold'em table

Getting 3:1 pot odds with zero rake heads-up blind vs blind, completing with a connected hand like 76o is standard.

J7 offsuit is a weak hand; checking the big blind option sees a free flop in a three-handed pot instead of building the pot out of position against a limper.

Flopped the nut straight on a rainbow board; betting for value to start building the pot against pairs and straight draws.

Jack-high with 7 on a low connected 4-5-3 board has almost no showdown value and only a backdoor straight draw. Folding to a 150 bet into a 350 pot is reasonable, though calling would also be defensible against a possibly wide range.

Opening AJo from the button with a standard 2.5bb raise to take initiative in position.

J3 offsuit is a weak hand; it plays poorly out of position against a button raise with a big blind still to act behind, so folding the small blind is best.

2c Jc is a weak offsuit-ish hand with a poor kicker, and I'm out of position against two live blinds with no strong reason to call 100 from the button. Folding is the cautious choice.

Heads-up with AJo against only the big blind; raising builds pot with a strong hand and can win preflop.

Q5o is too weak to defend against a 3x open from the small blind.

K6o on the button is worth a cheap steal attempt in 3-handed; a min-raise pressure often folds the blinds, and I retain fold equity if called.

42o is essentially unplayable out of position facing a 3x open raise from the button.

8s7o suited-ish connectors in the big blind getting 2.25:1 pot odds against a button open (3x) is a reasonable call; 87 offsuit has decent playability, and a 3-bet bluff is unnecessary.

I flopped top pair-plus: 8-7 on a 7-8-4 board gives two pair. I'm first to act out of position in a 650 pot, so I bet about 70% of the pot for value and to charge flush and straight draws.

K6-high missed the 7-4-8 flop and seat_3 bet into the preflop raiser; no equity worth 450 more.

Holding pocket Aces on the button 3-handed, making a standard 2.5bb opening raise for value.

Pocket kings in the small blind facing a button open to 250 with the big blind still to act. A 3-bet to 900 builds the pot and charges both opponents for playing against a premium hand.

32o is dominated and facing a 3-bet; folding is clearly best.

Holding pocket Aces in position against a 3-bet, 4-betting to 2300 builds the pot for maximum value.

Kings are a premium hand facing a 4-bet from the button. A 4-bet to 6000 builds the pot and leaves room for the opponent to shove with worse hands, and I'm happy to get all the chips in.

Holding pocket aces preflop against a 5-bet, pushing all-in to commit our opponent who is already pot-committed.

Pocket kings facing a 5-bet shove heads-up; calling the remaining 4000 to win a 16100 pot is clearly profitable against any plausible range.

3c8c is a weak offsuit-ish hand (suited but low connectivity) out of position against two players still to act behind in a 3-way pot, so folding on the button is a cheap, safe choice.

72o heads-up out of position is a trivial fold even for only 50 more; folding avoids playing a dominated hand.
