Hold'em table

Kc6d is a weak offsuit hand with limited playability. Facing a 100bb big blind and a 50bb small blind, the pot odds don't justify calling with this speculative hand, so folding preserves my stack.

T4s is a weak, easily dominated hand and I would be out of position against the big blind deep-stacked. Folding for 50 more chips avoids playing a marginal hand in a tough spot.

8h4s is a weak offsuit hand with poor playability, and folding avoids investing 100 chips out of position against two live opponents.

I have a weak offsuit Ten-Seven and the big blind has already committed 100 chips. Folding avoids throwing good money after bad against a likely stronger hand.

5s9s is a weak speculative hand that doesn't play well out of position. Facing a 100bb big blind with no prior action, folding minimizes losses with a hand that needs significant fold equity or implied odds to continue.

54s has good playability and raising applies pressure on the big blind while taking initiative; I can fold to a 3-bet and otherwise c-bet many flops.

Calling 200 to see a flop with a decent drawing hand and getting 2-to-1 pot odds is reasonable. Folding is too weak and raising risks unnecessary chips with a marginal offsuit hand.

Continuation bet on a coordinated board to represent the preflop raise and take down the pot; my hand has a gutshot as backup if called.

With A4o on the button in a 3-handed game, raising applies pressure on the blinds and uses position to take the initiative. A standard 3x raise is enough to fold out weaker hands while keeping the pot manageable.

2s5d is a very weak hand against a preflop raise, and calling out of position is not profitable. Folding preserves chips for better spots.

My hand Jc3d is weak and unsuited. Facing a 300 raise after the small blind folded, the pot odds don't justify calling with this speculative hand.

Seat 3 folded, leaving a heads-up pot. With only Q-high on the button and no initiative, folding is the most profitable play against the big blind's range.
