Hold'em table

Q8o is slightly too weak to open profitably from the button even in a 3-handed game.

Heads-up against only the big blind, A3o has solid equity and folding leaves my blind dead. A small raise to 250 builds the pot with ace-high and applies pressure while keeping risk low.

62 offsuit is too weak to continue against a preflop raise, so folding is the clear choice.

Ten-three offsuit is far too weak to invest a full big blind from the button against two players who have position on me postflop. Folding preserves chips for a better spot.

Button folded, so this is heads-up versus the big blind with AQo. Raising to 3bb builds the pot with a strong hand and denies a free flop.

75 offsuit is too weak to defend against a 3bb open from the small blind.

A3s is a playable button open in three-handed play; a standard raise builds the pot and takes initiative before the blinds.

Q9o is too weak to call or 3-bet from the small blind against a button open raise.

Facing a button min-raise, I need only ~31% equity and 97o has roughly 40-45% versus a wide button range, so the 200 call is defensible even out of position. Folding is too tight against a min-raise, and 3-betting this weak hand just builds a pot I'd rather not play OOP.

I hold second pair with a weak kicker on an ace-high flop against a preflop raiser, so I have little value and don't want to bloat the pot. Checking keeps the pot small and lets me evaluate their action before committing more chips.

Dry ace-high flop and I have top pair as the preflop raiser, so a small c-bet gets value and denies equity while keeping the pot controlled with a weak kicker.

Second pair with a weak seven kicker out of position against the preflop raiser's c-bet; I'm usually behind AK, overpairs, and sets with only ~5 outs, and turn decisions would only get harder.

K2o is too weak to open profitably from the button even in 3-handed play.

Pocket eights is a strong heads-up hand against only the big blind; raising builds the pot with a hand that often dominates BB's calling range and denies cheap equity realization.

A2o is too weak to continue out of position against a 3bb small-blind raise: the ace is often dominated and the deuce kicker plays poorly. Folding avoids reverse implied odds.

T9s is a strong suited connector and I'm on the button in a 3-handed game, so I have position and a wide opening range. Raising to 3bb applies pressure on the blinds and builds the pot with a hand that plays well postflop.

52s is too weak to continue from the small blind against a button open, especially out of position with the big blind still to act. Folding avoids a speculative call with poor equity and playability.

K9o is too weak to defend out of position against a 3x open from the button.

JTo is a strong button open in three-handed play, so I raise to 3x to take the initiative and fold out weaker hands.

Q2o is far too weak to defend out of position against a button open.

K2o is the worst king-high hand and is heavily dominated by any reasonable button raise range; calling 200 into 450 needs ~31% equity that K2o rarely realizes out of position. Folding is clearly best.
