Hold'em table

2-4 offsuit is too weak to open from the button for a full big blind, so folding preserves the stack.

Cheap call to see a flop heads-up with a live but weak hand; folding costs equity for minimal price.

Seat 1 folded and Seat 2 called the big blind, so the pot is 200 with no additional call required from me as the big blind. I will check to see a cheap flop with AsTd, keeping my stack intact while observing how the opponent plays.

I have bottom pair with a weak kicker on a wet board; no need to bet, checking to control pot size and see next card cheaply.

Checked through on the flop with a backdoor straight draw and no immediate threat; pot is small and I want to keep the hand cheap while seeing if the board develops.

Q-high with no pair or draw; checking to see a free river is best rather than bluffing into two players.

Checking back the turn keeps the pot small and denies the opponent a free card if they're weak; with Ace-high and a backdoor draw, I want to see a cheap showdown.

I only have bottom pair with a weak kicker and no strong reason to bet into two players who have checked every street; checking avoids unnecessary risk against a possible flush.

Board is paired with a flush draw, and my Ace-high is unlikely to be best; checking lets me see a cheap showdown and potentially win if opponent also has nothing.

2-6 offsuit is a very weak hand not worth playing from the button facing a raise-sized pot; folding preserves chips for better spots.

I have 5h8c which is a weak hand, and I'm out of position in the small blind. The big blind has already put in 100 and I only have 50 to call, but with such poor equity I should fold to preserve my stack.

I have a strong pocket pair (Qd Qc) and the pot odds are favorable. Calling 100 to see a flop is the standard play here.

AKo is a premium hand in a three-handed pot with a limper; raising to 400 builds the pot and takes the initiative before the flop.

6-2 offsuit facing a raise and a call is a clear fold; no equity to justify continuing.

I have Qd Qc, a strong hand. Seat 1 raised to 400 and seat 2 folded. I'll 3-bet to 700 to build the pot and isolate the opener.

AKo is ahead of a wide limp-min-3bet range and I am out of position, so a 4-bet builds the pot and takes the initiative rather than calling a cheap price.

Seat 1's 2200 raise with 7800 remaining is a strong signal; my Qc Qd is good but not strong enough to call 1500 into a 3000 pot out of position.

74s is too weak to open first in from the button against two live blinds, so folding avoids a marginal spot.

5-2 offsuit is a weak hand heads-up against the big blind after the button folded; folding preserves chips rather than calling with a poor hand.

K2 offsuit is a weak hand out of position facing action; not worth continuing preflop as button open would be marginal and I face a limp already.

9d 5h is a weak offsuit hand that lacks playability. The small blind has already entered the pot, and I am out of position with no fold equity, so folding minimizes expected loss.

I have Qd3h, a weak offsuit hand with poor playability. The pot odds don't justify calling 100 to see a flop with this hand.

82o is too weak to complete or raise from the small blind heads-up against the big blind. Folding avoids putting more chips in with a hand that plays poorly postflop.
