Hold'em table

A9 suited is a strong button open in three-handed play, so I raise to 2.5bb to take the initiative and build the pot.

J6 offsuit is far too weak to defend the small blind against a 2.5x raise, especially out of position with the big blind still to act. Folding is clearly best.

3-4 offsuit facing a raise with SB already out is a clear fold; not worth defending with a weak, unconnected hand.

A6s is a standard open-raise from the button in 3-handed play; taking the initiative with position and fold equity is profitable.

7c4c offsuit is weak, facing a 3bb raise from the button with a big blind still to act; not worth continuing.

A7o is a reasonable defend versus a button 3bb open heads-up; calling 200 into 450 is priced well enough to see a flop rather than fold or inflate the pot out of position.

Ace-high with no pair and no draw on 9-6-2; checking keeps the pot small and lets me realize a free card out of position.

I flopped second pair with an overcard after my preflop raise; betting ~half pot charges draws and gets value from weaker pairs while keeping the pot manageable out of position risk.

Ace-high with no pair and no draw on 9-6-2; calling a half-pot c-bet is -EV against a button raiser's range.

J2 offsuit is a weak hand not worth playing from the button facing a raise; folding preserves chips for better spots.

Q5 offsuit is too weak to complete or raise out of position against the big blind, so I fold and avoid putting more chips in.

42 suited is too weak to call or open from the button for a full big blind; folding preserves the stack.

A5s is a strong suited ace to open from the button 3-handed; a standard 3x raise builds the pot with position and fold equity.

Pocket queens are strong preflop; 3-betting the button's open builds the pot and denies a cheap look for seat_1.

A2s is too weak to continue out of position against a button open and a small-blind three-bet, with the button still left to act. Folding avoids a dominated ace and a bloated pot.

A5s has the right price to continue (need ~32%, have ~35%+ even vs strong ranges), and I'll be in position postflop with a hand that flops top pairs, flush draws, and wheel potential.

Overpair on a dry low board; bet for value and to charge draws/worse pairs.

I hold ace-high (A5) with no pair, no flush draw, and no straight draw on 7c-3h-2c, facing a ~63% pot bet from a preflop 3-bettor. Calling needs ~28% equity which I don't have against this range, and raising as a bluff here is too risky, so folding is clearly best.

Weak offsuit low connector (3c6c) on the button facing a raise-limp scenario isn't strong enough to invest chips; folding preserves stack for better spots.

Button folded, so this is heads-up versus the big blind. 75 suited has enough playability to raise small and take the initiative rather than limp out of position.

J8 offsuit is too weak to defend the big blind against a 2.5x raise out of position; the hand flops poorly and is often dominated, so folding is the profitable line.
