Hold'em table

I have King-high with a backdoor flush draw, which is marginal but playable. Calling 50 more chips keeps me in the pot without overcommitting with a weak hand.

I am in the big blind with a weak offsuit hand and no need to put more chips in preflop; checking takes a free flop against the limper.

I have no pair or strong draw on a king-high flop and am first to act against one limper, so checking keeps the pot small and avoids bluffing into an unknown hand.

I have a strong King-high with a 9 kicker on a dry flop, but the opponent checked behind so I'll control the pot and see a turn card without committing more chips.

I have second pair on a dry-ish board and the button limped/checked flop, so a small turn bet can take the pot or get value from worse pairs and draws. If raised, I can fold comfortably.

I have top pair with a decent kicker on a dry board, and calling 150 into a 400 pot keeps the pot manageable while preserving stack for river decisions. Seat 2 folded, so it's heads-up and I can control the action.

Board is coordinated with a flush draw and straight possibilities; my Kd gives top pair but I want to control pot size and induce bluffs on the river. Checking keeps me in the hand without committing more chips when I'm likely behind.

Button folded, so it's heads-up and I have K4s in the small blind. Raising to 300 applies pressure, takes initiative, and can fold out many big blind hands while keeping decent equity when called.

I have pocket Kings, a strong preflop hand. Seat 3 opened to 300, so I'm raising to 600 to build the pot and apply pressure while getting good odds.

K4s is too weak to continue out of position against the big blind's preflop reraise, especially with only 3:1 pot odds and poor implied odds.

Q4o is a weak offsuit hand with poor playability, and calling 100 chips out of position against two live players is not profitable. Folding preserves chips for better spots.

8d2s is a weak hand and I'm out of position as the small blind facing a raise. Folding preserves my stack for better spots.

I have Tc7c on the button with no action yet, but the blinds are already in. This is a weak suited hand that plays poorly out of position, so I fold to avoid losing chips with a speculative hand that has no immediate value.

62 offsuit is too weak to continue out of position against the big blind, and the extra 50 chips is not worth the poor equity and postflop disadvantage.

7s2c is the weakest starting hand and I am out of position against the big blind; calling 50 more is not worth it despite the small pot odds.

I have Qd 5h, a weak offsuit hand. The small blind already folded, and I only need to call 50 more to match the big blind. With such a marginal hand, folding is the safest play to preserve my stack.
