Hold'em table

Q6o is too weak to open from the button; folding avoids a dominated, low-playability hand out of position against continuing ranges.

J8 offsuit is weak heads-up vs BB with a call already priced in; not worth continuing for 50 more.

7-3 offsuit is a weak hand not worth playing from the button facing a raise-sized call; folding preserves chips for better spots.

6d 8s is a weak hand with no pair and poor connectivity. Facing a raise from the button with only the small blind posted, folding is the most prudent play to preserve chips.

I have 8d Ac, a weak offsuit hand with no synergy. I'm on the button with no pressure to defend, so folding is the most chip-efficient play.

42 suited is too weak to complete out of position against the big blind after the button folds, so I take the free fold.

J9 suited is a standard button open in three-handed play. A 2.5bb raise builds the pot with a playable suited hand and applies pressure to the blinds.

43o is a weak hand facing a raise plus a call cold, not worth continuing from the small blind.

With only Ace-high and no pair, calling 150 more to see a flop is too expensive relative to my hand strength, so folding is the safest play here.

Button with J9o; raising for a steal/isolation with position advantage over both blinds.

I have 9d7d, a weak suited hand that is unlikely to hold up against a raise from the button. Folding preserves my stack instead of putting money in with poor equity.

AKs is a premium hand against a button open and a folded small blind, so I 3-bet to 900 for value and to take the initiative out of position.

J9o facing a 3-bet to 900 is a clear fold; not strong enough to continue against a re-raise.

I have 2d Jd, a weak offsuit hand with no pair and low equity. Facing a 100bb pot-sized raise effectively, folding is the correct play to preserve my stack.

32 offsuit is the worst hand and I am out of position against the big blind, so calling or raising is not worth the extra chips.
