Hold'em table

On the button with an ace-high hand in a 3-handed pot, a standard open raise applies pressure to both blinds.

Nines are strong in a 3-way pot and I have position on the raiser; 3-betting builds the pot with a hand that flops well and applies pressure to the button's wide opening range.

T7o is too weak to continue facing a button open and a small-blind three-bet to 800. Folding avoids putting more chips in with a dominated offsuit hand out of position.

A2 offsuit facing a big 3bet from a seat claiming a strong pocket pair; my equity is marginal and not worth the risk this early.

Suited connector 45s plays well in position; a standard 3x open applies pressure and can win blinds or build a pot with a hand that flops well.

J6 offsuit is too weak to continue against a button open for 250 more, so I fold and wait for a better spot.

3d4d is weak offsuit-connector-like but low value against a raise; facing a 3x raise heads-up with a marginal suited connector-ish hand isn't worth continuing, folding to preserve chips.

A7o is playable on the button in three-handed poker, and opening to 3bb is better than limping or folding with position.

5-3 offsuit is weak, facing a 3bb raise from the button with a call behind; not worth continuing.

King-three offsuit is dominated by any better king and plays poorly out of position against a button raise. The small pot odds don't justify chasing a weak kicker for two more streets of tough decisions.

4-2 offsuit is a weak hand from the button facing a raise; not worth continuing.

King-Jack offsuit on the button in 3-handed play is a standard opening raise; I'll apply pressure and try to win the blinds or play in position.

34 offsuit is too weak to continue against a button open, especially with the big blind still to act. Folding saves chips.

87o is weak, facing a raise with only heads-up equity left; not worth defending.

AJs is a strong button hand and both blinds are still live, so a standard 3x open builds the pot and takes the initiative.

A6o is too weak to continue against a button raise with BB still to act; folding preserves chips for better spots.

QTo has decent equity against a wide button open in 3-max, and I only need to call 200 into a 450 pot. I'll see a flop before committing more from out of position.

I hold a queen-high flush draw out of position against the preflop raiser; checking keeps the pot small, wins a free card if he checks back, and preserves the option to call or check-raise if he c-bets.

I have top pair with a strong kicker on a relatively dry board, and the big blind checked. A half-pot bet gets value from worse aces and draws while keeping the pot controlled.

Q-high with only a weak diamond draw against a preflop raiser betting an ace-high board; I lack the equity to call 350 profitably and no fold equity story is worth pursuing here.
