Hold'em table

I'm on the button with 5c Kh, which is weak and unsuited. The blinds have already posted, and I'd rather preserve my stack than play a marginal hand out of position.

Q4o is too weak to complete or raise out of position against the big blind after the button folded, so I give up the small blind.

A6o is a standard button open in three-handed play; raising to 2.5bb takes the initiative rather than limping.

KJo is strong enough to 3-bet the button's open in a 3-handed spot, applying pressure on both the button and BB while building the pot with a decent hand.

My hand (5s 8h) is weak and disconnected, and I am facing a significant preflop raise to 800. Folding preserves my stack for better opportunities.

A6o is too weak to continue against a 3-bet: it is dominated by stronger aces and has poor equity and reverse implied odds, so folding is best.

6d-Th offsuit is weak from the button facing a raise-limp situation; not worth continuing given poor equity.

I have 9c Qd, a weak offsuit hand. The small blind already folded, so I'm heads-up against the big blind. I'll fold to avoid losing more chips with a hand that's unlikely to win at showdown.

6d7s is a weak speculative hand with no pair and limited playability. Facing a 100bb raise from the big blind with no other callers, folding preserves my stack for better spots.

Button folded, so this is heads-up versus the big blind. Ace-deuce offsuit is weak but has enough equity to raise small and take the dead money or play a controlled pot.

Q9 offsuit facing a 3x raise from SB with a fold behind already; not worth defending, better spots exist.

Q8o is a marginal button open in 3-handed, but position and a standard 2.5bb steal make raising better than limping or folding.

9-8 offsuit facing a button raise with BB still to act is not worth defending as SB out of position; folding is cheap here.

2d6c is a weak hand with poor equity against seat_2's preflop raise to 250; folding avoids losing chips with a speculative hand that is unlikely to improve enough to justify calling.

Button with K5 suited-ish (offsuit K5, actually suited diamonds K5d) - decent speculative hand, cheap call to see flop in position.

Th-6h is a weak hand with no playability; calling 50 more into a 250 pot with a disconnected hand is not profitable, and folding preserves my stack for better spots.

73s is too weak to isolate a button limp for value, and checking is free with position still to come postflop.

Middle pair with a weak kicker on an ace-high two-club board has some showdown value but is too thin to bet into the limper. Checking keeps the pot small and lets me react.

I have king-high with a backdoor flush draw and no pair; checking behind is fine since I can check for free and no bet is required.

I have aces and sevens on an ace-high board, and the button’s flop check makes a strong ace less likely. A small turn bet gets value from worse pairs and draws while keeping the pot manageable.

I have no pair, no draw, and only king-high on a paired ace board; not worth continuing against a bet.
