Hold'em table

Kd6s is a weak hand on the button with two opponents already invested; folding avoids a costly bluff with poor equity and position disadvantage.

8-2 offsuit is one of the weakest hands in poker. With only 50 more chips to call and a weak holding, folding is the mathematically sound decision to minimize losses.

K2s is a weak hand from the button facing a raise. Even though position is favorable, the hand lacks strength and will likely be dominated in a 3-way pot. Folding preserves chips for better opportunities.

T5o is too weak to complete or raise from the small blind, so folding is the standard play.

K5o is too weak to open profitably from the button even in 3-handed play.

With 2c-Ah in the small blind, I'm facing a 50 chip call to see a flop. This is a weak hand that plays poorly out of position, so folding is the correct play to preserve my stack.

I have Ace-high with backdoor flush and straight potential. Calling 100 chips keeps me in the hand without overcommitting preflop with a weak holding.

9-To is a weak hand in early position. Seat_1 called the big blind and I'm facing a decision from the big blind position. Folding preserves chips with a marginal holding against potential aggression.

We have K8s in the big blind facing a button limp and SB fold; checking to see a free flop is standard and avoids building an unnecessary pot out of position.

I flop an open-ended straight draw on a paired board out of position in a limped pot, making a standard check optimal.

The board is paired with 77 and I hold Ac3c, which is a weak hand with backdoor flush and gutshot possibilities. Checking keeps the pot small and avoids building a bigger pot with a marginal holding against a likely strong range.

I have an open-ended straight draw with K-high on a paired, three-flush board out of position; checking to realize equity is best.

Board is 7765d with Ac3c; checking keeps the hand cheap and avoids building a pot with a weak kicker. If opponent bets, I can decide to call or fold based on their sizing.

I have two pair with a King kicker on a double-paired board; checking to reach showdown with good showdown value in a checked-down pot.

The board is paired with 7s and 6d, and my Ace-high is unlikely to be best. With no money in the pot on the river and a weak hand, checking is the safest play to avoid building a bigger pot with a losing hand.

9-Jack offsuit is a marginal hand in early position that doesn't warrant calling the big blind. With two opponents already committed and limited implied odds, folding preserves chips for stronger starting hands.

J4o is too weak to complete out of position against the big blind.

86 offsuit is too weak to open from the button even in 3-handed play.

9c 6h is a weak hand and I'm out of position as the small blind; folding avoids losing more chips with almost no equity against the big blind's 100 chip bet.
