Hold'em table

J8 offsuit is a weak hand on the button facing a raise to 100 in a 3-handed pot; folding preserves chips for better spots.

Q2 offsuit is too weak to complete out of position against the big blind after the button folds. Folding saves the extra half-blind rather than playing a dominated hand.

AK offsuit is a premium button hand, so I open to 3x the big blind to build the pot and take the initiative.

5d 7c is a weak offsuit hand that cannot profitably call a 250 chip raise from the button with only 50 big blinds effective behind. Folding preserves my stack for better spots.

I have 5h 9h, a weak offsuit hand with no pair and backdoor flush potential only. Facing a 100bb big blind and a 50bb small blind raise, the pot odds and hand strength don't justify continuing preflop.

Cheap price to see a flop heads-up with a suited-ish weak hand; folding here loses value given the pot odds.

83s is too weak to raise against a completed small blind, and checking is free, so I take the flop.

No pair or draw with 2c8c on this Q-high board, checking to see a free card cheaply.

I have a spade flush draw and position after a check, so a half-pot semi-bluff can take the pot now or build it when I improve.

2c8c missed the flop completely with no pair, no draw, and facing a min-raise; not worth continuing.

54o offsuit is a weak hand not worth playing from the button facing a raise-sized pot; folding preserves chips for better spots.

43o is too weak to continue out of position for another 50 after the button folded; raw equity does not cover the postflop disadvantage.

K7o is playable as a button open in 3-handed; a small raise takes the initiative and can win the blinds.

6s 9h is a weak offsuit hand that plays poorly out of position. Facing a raise to 250 with only 50 invested, calling requires too much with poor equity, so folding is the correct play.

A3 offsuit is playable heads-up against a single min-ish raise from the button, and I'm getting good pot odds to see a flop from the big blind.

I flopped top two pair (aces and threes) which is very strong here, so I bet for value to build the pot against a preflop raiser.

King-high with no pair and no draw on an ace-high flop; calling a sizable lead is -EV and a bluff-raise has little fold equity.

I have 8h-As, a weak offsuit hand on the button. The small blind has already invested 50 and the big blind 100, so I'd need to call 100 to continue. With no information about their hands and a mediocre holding, folding minimizes losses in this spot.

Heads-up after button folds, K3 suited is strong enough to raise for value/steal against BB.

K7o is dominated and too weak to continue against a 3bb small-blind open, even with position. Folding avoids reverse implied odds and a marginal call.
