Hold'em table

Q8 offsuit is too weak to open from the button into two live blinds; folding avoids a dominated spot and a bloated pot out of position relative to hand strength.

I hold 3h Ad, a weak offsuit hand that is unlikely to win against the small blind's range. Folding preserves my stack and avoids losing chips on a poor starting hand.

I have a weak disconnected hand (Ts3c) and am out of position facing a raise. Folding preserves my stack for better opportunities.

AQ offsuit is a strong hand heads-up against the big blind; raise to isolate and build the pot.

57o is too weak to defend against a 3bb raise, even heads-up after the button folded. Folding saves chips for better spots.

Ace-high suited with a wheel card is a solid button raise against two limped/blind hands; a standard 3x open builds the pot with position advantage.

Q9 offsuit is too weak to call a button raise out of position for 2.5bb more, with the big blind still to act.

I hold 9c7d, a weak hand that is unlikely to stand up against a preflop raise from the button. With only 200 chips to call and no strong equity, folding preserves my stack for better spots.

K2o is too weak to open from the button; it is dominated by better kings and has poor playability, so folding is the highest-EV option.

I have a pocket pair of 8s, which has decent playability preflop. The small blind is only 50 chips to call, and the pot is 150, giving me 3:1 odds. I'll see a flop to improve my hand.

I'm the big blind with A2 offsuit and no raise to face; checking is free and keeps the pot small with a weak hand.

I have a set of 8s on a dry flop and can check to control the pot size and induce bluffs from the button while keeping my hand disguised.

I have A-high with no pair or draw on a J-Q-3 board; no value in betting, checking is free and keeps pot small.

I have a set of 8s on a J-high board with two overcards, but the pot is small and both players checked. Checking keeps the pot manageable and avoids building a big pot with a vulnerable hand.

I only have ace-high with no pair or draw, so checking is best given no bet to face.

I have a set of 8s on a board with a paired J and a Q, but the opponent checked twice on the turn and river, indicating weakness. Checking allows me to potentially induce a bluff or win the pot at showdown without risking more chips.

I have only ace-high with no pair; no value in betting into two players who both checked through, so I check to see a showdown for free.

I have Th9h in the big blind facing a 100bb pot with no equity advantage; folding avoids losing chips on a speculative hand out of position.

Weak offsuit low cards (5h2h low connectivity, not even suited high card) heads-up vs BB with only 50 to save; folding is cheap and correct.

JTs is a strong suited connector on the button; raising to isolate and build pot with position.

Q2 offsuit is too weak to continue from the small blind against a button open, with the big blind still to act.

With K2o, I have almost no chance to win against a button raise. Folding preserves my stack for better spots.
