Hold'em table

Q6 offsuit is too weak and dominated to open even from the button in three-handed play, so folding avoids a poor spot.

J8o is weak out of position against the big blind; folding avoids difficult postflop spots with reverse implied odds.

Holding 73 offsuit on the button is well outside any reasonable opening range, so folding is the clear optimal play.

6d8s is weak even for a cheap completion; heads-up against the BB with no dead money, folding the SB is the profitable line.

A8o on the button three-handed is a standard steal spot; raising to 300 builds fold equity and keeps initiative with position against the blinds.

42s is too weak to call a button open out of position for 2.5bb; folding preserves chips.

J4o is too weak to defend out of position against a 3bb open raise.

J9 suited is a strong button open in three-handed play; a 3bb raise builds the pot and applies pressure before the flop.

Folding 4h 3d from the small blind facing an open raise from the button.

Opening J9 offsuit from the button in 3-handed play is standard to apply pressure on the blinds with positional advantage.

97s is far too weak to call 175 more out of position against a button raise; folding is the standard profitable play here.

Ace-king suited is a premium hand against a button open, so I three-bet to build the pot and take control while heads-up.

J9o is too weak to continue against a 3-bet from the big blind.

J2s is too weak to call from the button; a standard 3x raise applies pressure on SB and BB and can take the pot preflop.

32 offsuit is too weak to continue out of position against a button open, so folding is the highest-EV option.

Q2o is far too weak to defend against a 3x button open out of position.
