Hold'em table

4s-Ks is a weak hand in early position (button), and calling 100 chips doesn't have sufficient equity against the likely stronger ranges of the small blind and big blind. Folding is the mathematically sound play here.

With the button folded, this is heads-up and T6 suitedness aside has enough equity to open from the small blind. Raising applies pressure and avoids conceding the blind.

I have a playable broadway hand getting good pot odds (150 to call into 350), and I close the preflop action against a likely wide small-blind raise. Folding is too tight, while 3-betting with TJo risks bloating the pot out of position.

A small continuation bet leverages our preflop range advantage on this ace-high paired board and can fold out many unpaired hands.

I have no pair and only weak overcards on an A-high paired board. Facing a flop bet from the preflop raiser, folding is best because my equity is poor and I have no credible draw.

8-5 offsuit is a weak button opening hand in this configuration, so folding avoids playing a dominated, low-equity pot.

With K2o in the small blind after the button folds, I only need to call 50 into a 150 pot, giving good pot odds to see a flop against the big blind. The hand is weak, so I avoid bloating the pot with a raise.

6-9 offsuit is a weak hand with poor connectivity and low showdown value against the small blind in 3-handed play. Folding is the optimal play to minimize losses.

2h6s is a very weak offsuit hand with poor equity and playability, even on the button in a 3-handed game. Folding avoids investing chips with a bottom-tier starting hand.

6-7 offsuit is a weak hand with poor winning potential from small blind. Against the big blind's raise, folding minimizes losses and preserves chips for stronger opportunities.

3-Q offsuit is a weak hand in 3-handed play, especially out of position. Folding minimizes losses when facing a big blind raise with poor equity against likely calling or re-raising ranges.

With the button folded, A2 offsuit is a strong heads-up small-blind holding and benefits from applying preflop pressure.

Getting 3:1 pot odds with a suited connector in position, closing the action preflop; call to see a flop.

With the weakest possible ace on this paired board, checking controls the pot against the many stronger Ax hands while retaining bluff-catching value.

My hand has no pair or strong draw on a paired ace-high board, and the opponent checked; checking controls the pot and avoids bluffing into a likely made hand.

Bet half pot for value and protection with trips against tens, sevens, diamond draws, and weaker aces. A modest size keeps weaker hands involved while limiting exposure to stronger ace kickers.

I have 5-high with no pair or draw on an A-high paired board, and calling 300 would require significant equity I do not have. Folding avoids further losses against a likely strong range.

Pocket fours is a playable button opening hand three-handed. Raising to 3bb applies pressure and builds a pot with a concealed set-mining hand.

Q8o is weak and out of position against a button raise, with poor playability and domination risk. Folding avoids investing more chips in a marginal spot.

3-2 offsuit is the worst possible hand in poker. Facing a raise to 300 from the button, folding is correct to preserve chips and avoid playing out of position with a hopeless hand.

Three-handed button open with a suited J6; raising applies pressure on the blinds and uses position if called.

King-eight offsuit is a marginal hand facing a 2.5x raise from the button after already committing the small blind. The risk-reward isn't favorable enough to justify calling 200 more chips when position and hand strength are both disadvantageous.

A8 suited is strong enough to defend against the button open, and a 3-bet applies pressure while retaining strong equity when called.

J6s is too weak to continue against a large big-blind 3-bet, especially with poor playability and domination risk. Folding preserves chips.
