Hold'em table

Weak offsuit low cards (2-4) with no connectivity, not worth entering the pot from the button facing a raise.

Button folded, so I only need 50 more to see a flop heads-up against the big blind. Q5o is weak, but the price is good enough to complete rather than fold or inflate the pot.

Seat 1 folded and seat 2 completed the big blind, so I can check behind with AsTd. I want to keep my stack intact and see a flop without committing more chips on a marginal hand.

I have bottom pair with a queen kicker out of position on a jack-high, two-heart flop. Checking keeps the pot small and avoids building a pot I may have to fold to pressure.

Checking back with Ace-high on a dry flop keeps the pot small and preserves initiative; I can reassess on later streets.

Bottom pair with a queen kicker is too thin to bet into the big blind on this turn, so I check to control the pot and realize equity for free.

The board is dry and I have a weak Ten-high with backdoor flush/straight potential; checking keeps the pot small and avoids building a big pot with a marginal hand.

Pair of fives is too thin to value bet on a three-heart, connected river, and a bluff into a player who checked every street is unlikely to fold better. Checking realizes showdown value in a small pot.

I have Ace-high with a Ten kicker and no made hand, so I want to see a showdown cheaply. Checking keeps the pot small and avoids bluffing into a likely better hand.

26o is too weak to open from the button for a full big blind; folding preserves the stack for better hands.

I have 5h 8c, a weak offsuit hand that doesn't play well from the small blind. The big blind has 100 invested and I only have 50 to call, but the pot odds don't justify chasing with this hand.

I have a strong preflop hand with Qd Qc and the pot odds are favorable at 150 in the pot with only 100 to call. Calling keeps my stack intact while seeing a flop with a premium pair.

AK is a strong hand; raising to isolate limpers and build the pot while I have position on future streets is +EV.

62 offsuit is far too weak to continue against a raise and a caller, so folding is the clear choice.

I have Queens on the button and the only remaining opponent is the small blind who raised to 450. Calling 350 is reasonable to see a flop with a strong hand, and I want to keep my range wide for future hands.

I hit top pair top kicker on a K-high board; betting for value against a likely queens hand that missed.

I have a pair of queens on a K-8-3 flop, which is a decent second pair. Seat 1's continuation bet of 600 into a 1600 pot is moderate, and calling keeps my hand's strength hidden while controlling the pot. Folding would be too weak, and raising risks building a big pot with a marginal hand.

I hold trip kings with an ace kicker on a paired king board, a very strong holding that beats likely two-pair or set hands like QQ; betting for value to build the pot while there's little realistic overcard risk.

I hold Qc Qd, giving me a set of queens on a K-8 board. Calling is correct because I have a strong made hand and a full stack behind to play for a large pot; raising risks getting re-raised into a tough decision, while calling keeps the pot controlled and lets me extract value on the river.

I hold trip kings with an ace kicker, well ahead of a claimed queens hand; opponent is already pot-committed after two big calls, so an all-in maximizes value.

Seat 1 has shoved all-in on the river with a board showing two kings and a possible set; my QQ is likely dominated by a stronger king or trips, and calling 7550 to win a 12550 pot is a negative EV decision.

7h4h offsuit is a weak hand not worth calling from the button; folding preserves chips for better spots.

52o is too weak to call or raise heads-up against the big blind after the button folds. Folding saves the remaining stack for better spots.

K2o is too weak to open from the button even with position; folding avoids a dominated, low-playability hand.

9d 5h is a weak hand with no synergy, and I'm out of position as the small blind facing a 50 chip call. Folding preserves my stack for better spots.

I hold Qd3h, a weak offsuit hand with poor equity against two opponents who have already posted blinds. Folding preserves my 100bb stack for better spots.

27o-type weak hand (2h8s offsuit) heads-up vs BB with button folded; not worth defending SB with such a weak holding, especially with only one opponent left to act.
