Hold'em table

Ks5s is a weak hand on the button with two players already invested; folding avoids losing chips with poor equity against the blinds' range.

7-4 offsuit is a weak hand with button already folded; not worth completing against BB.

7-4 offsuit is a weak hand not worth playing from the button facing a raise-sized call; folding preserves chips for better spots.

J6s in the small blind is marginal but calling 50 to see a flop heads-up against the big blind is cheap and reasonable.

7h2c is a weak hand and I'm out of position; folding avoids losing chips with almost no equity.

T5o off the button is a weak hand; folding is standard with no reason to defend.

4c 9s is a weak offsuit hand, and I'm out of position as the small blind facing a big blind who has already invested more. Folding preserves my stack rather than throwing chips into a pot I'm unlikely to win.

8c7c is a speculative suited connector that benefits from implied odds and multiway pots, so I'm calling the 100 big blind to keep the pot in play and see a flop. Folding would waste potential equity, and a min-raise isn't clearly justified without reads.

Small pocket pair in a cheap multiway pot; completing for set value is better than building a big pot out of position.

J5 offsuit is weak; free flop from the BB is the best option.

Pocket sixes on an A-K-4 board have little equity; checking avoids building a pot I likely lose.

J5 offsuit missed the AK4 flop; checking is free and folding costs nothing later.

Board is dry and I have no made hand, so I'll check behind to realize equity cheaply and keep the pot small.

Pocket sixes with no set on a board showing A-K-4-2 is weak; checking is free and avoids building a pot I'm likely behind in.

J5o whiffed the AK42 board; with no fold equity worth betting and a free showdown possible, checking is clearly best.

The board is paired with an Ace and King, and my 8c7c is a weak hand that likely missed. With no money in the pot and a check to me, I will check to control the pot and avoid building a big bet with a marginal hand.

I have two pair (sixes and fours) which likely beats the checked-down range; a small value bet can get called by worse hands like top pair or lower pairs.

I hold jack-high with no pair on an A-K-4-4 board; seat_2's river bet is very likely an ace or four. Calling 150 to lose almost always is worse than folding.

I have a pair of fours on the river, which is a decent hand but likely behind a strong bet. Calling is better than folding since I can still win if the opponent is bluffing or has a weaker hand.

9c2c is a very weak hand out of position heads-up against the big blind; folding the extra 50 is cheapest.

7h4s offsuit is a weak hand out of position with two players left to act; folding is clearly best.

I hold a weak 2c2h and the big blind is already in with a strong range, so I fold to avoid losing chips with poor equity.
