Hold'em table

Button raise with a suited king in a 3-handed pot is a standard value/steal play.

7d4c is a weak hand facing a 2.5x raise from the button; folding is clearly best.

With only Ace-high and a weak kicker, I don't have enough equity to call a raise from the button. Folding preserves my stack for better spots.

72o is a trash hand out of position; folding is clearly best.

6d Jc is a weak offsuit hand, and I'm out of position facing a raise from the big blind. Folding preserves my stack for better opportunities.

I hold a weak offsuit hand (T5o) and face a 100 chip call with no position or initiative; folding preserves my stack for better spots.

4c9s offsuit is weak; with only heads-up pot odds against BB and no fold equity benefit, folding is cheaper than continuing with a trash hand.

Suited connector on the button in a 3-handed pot; raising to apply pressure and take initiative.

I hold J5o, a weak hand that cannot withstand a 150-chip call facing a raise from the button. Folding preserves my stack against a likely strong range.

5s6h is a weak suited-connector-less hand from the button facing a limped pot; folding is fine, though calling is close. Fold avoids marginal spots.

I hold 9c2c, a very weak hand. The big blind has already invested 100 and the small blind only 50, so there is no fold equity to chase. Folding saves my remaining 9950 chips for better spots.

4s7h is a weak offsuit hand with no clear play against a raise from the big blind. Folding preserves my stack given the poor equity and lack of position.

Heads-up vs BB with a pocket pair, raising for value and to take initiative since the button folded.

J8s is far too weak to call 200 more against a 3bb raise heads-up; folding preserves chips.
