Hold'em table

Q8o is a weak, disconnected hand from the button facing a bet; folding preserves chips for better spots.

96s is too weak to continue out of position for another half-blind after the button folds. Folding keeps the loss to the small blind.

J6s is playable as a button open in three-handed play; a 2.5bb raise takes the initiative and can fold out worse hands.

7-2 suited is a trash hand facing a button open with the big blind still to act behind; folding from the small blind is clearly correct.

9c6c offsuit is weak against a button raise; not worth defending out of position for 150 more.

K8o on the button in a 3-handed game is a standard open; raising to 2.5bb applies pressure on the blinds and takes initiative.

J5 offsuit is weak; facing a raise with poor odds, folding is best.

J6 offsuit is too weak to continue out of position against a button open; folding saves chips.

K5o is marginal but button position allows a standard steal-raise against two opponents with 100bb stacks.

75o is too weak to continue against a button raise for 200 more. Folding preserves chips.

J8o in the big blind facing a 2.5x button raise: getting 150 to win 400, good price to defend with a playable hand in position-disadvantaged but heads-up pot.

I have J8 offsuit with no pair on a 99A board, out of position against the preflop raiser. Checking to see what the raiser does; a lead bluff is marginal and I prefer to keep the pot small with air.

As preflop raiser I can represent the ace on this dry A99 board; opponent's check suggests weakness, so a half-pot continuation bet is profitable.

J8 offsuit has no pair, no draw on a paired ace-high board against a button raiser's continuation bet; calling 300 into 850 with only jack-high and weak backdoor equity is unprofitable, so folding is the clear choice.

Ace-five suited is a strong button open in three-handed play, so I raise to 2.5bb to take the initiative and fold out weaker hands.

J7 offsuit in the small blind facing a 2.5x button open is a clear fold; it plays poorly out of position and is dominated by much of the button's opening range.

5d7h offsuit is weak and not worth calling a raise out of position with only a gutshot/weak draws potential.

On the button in a 3-handed game, 54o is a marginal but playable open; raising to 2.5bb takes positional initiative and often wins the blinds, while folding is also acceptable. Keeping it small to control risk.

K7 offsuit from the small blind facing a raise isn't worth defending; folding preserves chips for better spots.

94s is too weak to defend out of position against a button open after the small blind folds; calling realizes poorly and a reraise is a bluff with little fold equity.
