Hold'em table

Button opening range can be wide three-handed; K5 suited is a profitable open. I use a standard small raise size to pressure the blinds while retaining maneuverability.

K2o is a weak hand, especially offsuit. Facing a 250 chip raise (2.5x) from the button in early position, folding is the correct play. The risk-reward is unfavorable given hand weakness and position disadvantage.

Getting 2.67:1 pot odds with 8-6 offsuit, which has sufficient equity against a button raising range; calling to see a flop.

I have a weak 8-high hand with only backdoor straight and flush potential. Checking keeps the pot small and lets me see how the preflop raiser proceeds on this board.

A small continuation bet applies pressure to missed overcards and weaker pairs while retaining a manageable price with a gutshot straight draw and overcard potential.

My 8c6s has no pair and only weak backdoor/gutshot potential on a Q-high flop. Facing a bet from the preflop raiser, folding is the most chip-preserving play.

Ad4d has decent playability with ace-high and flush potential. Raising from the button against a small blind and big blind maximizes positional advantage and builds a pot we can win with aggressive play or premium cards on the flop.

Q7s is a marginal suited hand out of position against a button raise, with the big blind still to act. Folding avoids putting in 350 chips with a dominated hand and poor playability.

Ah-Ks is a premium hand heads-up against the button's open. A substantial 3-bet extracts value and pressures their opening range.

Ad4d is a weak hand that loses to most of seat_1's reasonable raising range. Facing a 3-bet to 1200, folding preserves chips for stronger opportunities rather than playing a marginal hand out of position.

Ace-king offsuit is a strong three-handed opening hand; raising to 3x the big blind applies pressure and builds the pot with the best hand.

A4 offsuit is too weak to defend from the small blind against a button 3x open with the big blind still behind.

On the button in a three-handed game, T6 suited has enough playability to open-raise and pressure the blinds. A modest sizing preserves maneuverability while leveraging position.

9c7c is a weak hand in 3-way action. Seat 1's raise to 250 (5BB) is a strong signal, and calling requires 200 more chips to risk 250 total in a pot of 400, giving poor odds with a hand that will struggle post-flop against a raiser. Folding preserves chips.

Q5o is a weak, dominated hand out of position against a button raise; folding avoids investing more with poor playability.

9-4 offsuit is a weak hand in early position. With a small blind and big blind already committed, folding minimizes losses from a poor starting hand that is unlikely to win without improvement.

K8s has good equity against a random big blind and raising to 300 applies pressure while taking initiative.

2h4h is too weak to defend against a small-blind raise heads-up, especially out of position postflop.

ATs on the button in a 3-handed game is a strong open; raising to 3bb applies pressure and builds the pot with position.

Kd9c is a playable defend versus a button min-raise with deep stacks, and calling preserves position-relative pot control in a likely multiway pot.

T7o is a weak hand in this spot. Facing a raise from seat_3 to 300 and a call from seat_1, I'm in the big blind with poor hole cards that don't play well multiway. Folding preserves chips against two opponents who have already shown strength.

Position and preflop aggression favor a continuation bet on a dry-ish board; my ace-high with backdoor clubs can fold out better unpaired hands and take the pot uncontested.

Kd9c has only a weak overcard and a thin backdoor diamond draw on this coordinated board. Calling the large continuation bet lacks sufficient immediate equity.
