Hold'em table

Pocket eights on the button in 3-handed play is a clear open-raise; 2.5bb sizing builds the pot while keeping it efficient.

9h4d is a weak hand facing a 2.5x raise from the button; folding is cheapest.

T6s is too weak to defend out of position against a 2.5bb button raise.

32o is the worst hand in the deck; folding on the button facing a raise is trivially correct.

Q4o is too weak to play out of position from the small blind against the big blind.

6h 2c is well outside any reasonable opening range on the button in 3-handed play. Easy fold.

Blind vs blind with 64o; a raise-first-in strategy from the SB is reasonable and puts pressure on the BB, while limping is also viable. Raising to 3bb with a mixed range.

7d8s is a weak suited connector facing a 3x raise out of position; folding is cheapest and preserves chips.

Three-handed on the button, Q4o is a marginal but playable steal against two blinds, so I'm opening to 2.5bb to pick up the blinds and keep position postflop.

Q5o is too weak to 3-bet but cheap to call 200 more with position; fold is fine too, but calling keeps speculative value low-cost.

Getting 5:1 pot odds closing the action preflop with QTo, calling 150 more is profitable.

I have queen-high with a gutshot-ish backdoor at best; with three players and an ace on board, checking behind in position is the safe line.

I have a gutshot straight draw multiway with the preflop raiser yet to act behind me, making a check standard.

The ace-high board favors my button open range and both blinds checked. A small one-third-pot c-bet takes the pot often, and my backdoor flush draw plus queen overcard give some equity when called.

I only have a gutshot-ish Q-high with no pair on an A-high board; seat_1 bet into two players and I have no equity worth calling 250 more with.

I only have queen-high with backdoor possibilities on an ace-high board, offering insufficient equity to call a flop bet out of position.

Q4o is too weak to complete or raise from the small blind out of position against the big blind.

Q8o is at the bottom of the button opening range and can be folded cleanly to avoid marginal spots.

Blind vs blind with suited connectors, 87s is a solid raising hand from the SB. A 3x raise takes initiative and can win the pot preflop.

K3 offsuit is dominated by a 3x raise; folding is clearly best heads-up.
