Hold'em table

Q6 offsuit is weak from the button facing a raise-sized call in a 3-handed pot; folding avoids marginal spots.

Suited connector 54s is cheap to complete from the small blind 3-handed and can make straights or flushes; folding loses too much equity for only 50 more.

Jack-seven offsuit is too weak to raise for value after the small blind completes, and checking is free. I will see a flop and reassess.

I have 54o with no equity or draws on an AK9 board against two limpers, so bluffing is unprofitable; checking costs nothing and I can fold to any bet.

J7o has no pair, no draw, and no relevant blockers on AK9. With the option to check for free, there is no reason to bluff into a range that can easily continue.

I hold 5-high with no pair or draw on an A-A-K-9 board. Checking is free and preserves the option to fold if seat_3 bets; bluffing into aces-heavy board is not worth it for a 200-chip pot.

Jack-high with no draw on a paired ace board has no value to bet, and seat_2 already checked. Checking keeps the pot small and avoids turning a weak hand into a bluff.

I hold 5-high with zero showdown value, so checking guarantees losing the pot. Opponent checked every street, indicating weakness, so a pot-sized bluff of 200 into 200 needs folds only ~43% of the time to profit.

My J7 does not improve the board, so I only have ace-pair with K92 kickers. Any two hole cards beat that, so calling 200 is a guaranteed loss.

K9o on the button is a standard opening hand in 3-handed play; raising builds the pot with position and can win blinds immediately.

45o from the small blind is too weak to continue against a button open, especially out of position. Folding saves chips for better spots.

AK offsuit-strong hand; 3-bet button's open to build pot and isolate, since SB folded.

K9 offsuit is badly dominated against a 3-bet range and calling 650 into 1200 needs ~35% equity I don't have. Folding is clearly the profitable play.

Suited connector on the button in a three-handed pot is worth a standard open rather than a flat or fold. Raising to 300 builds the pot with position and fold equity.

Q3 offsuit is weak facing a 3x raise from the button; not worth continuing from the small blind.

K5 offsuit is too weak to defend out of position against a 3x button raise; even with decent pot odds, postflop realization with a dominated king and bottom-pair kicker is poor.

9-3 suited is too weak to invest chips with in a 3-handed pot; folding preserves stack for better spots.

K8o heads-up against only the BB is worth a small raise for fold equity and position; min-raise keeps risk low while applying pressure.

Q7o is too weak to continue against a raise: it is easily dominated and plays poorly even with position and a cheap price. Folding avoids reverse implied odds.

King-four suited on the button in 3-max has decent playability and position, so a standard open keeps pressure on the blinds and can win the pot or build with a suited hand.

K6 offsuit is too weak to continue out of position against a button open, so folding preserves chips.

J7 offsuit facing a 3bb raise from the button is weak; folding avoids a marginal spot out of position.

76s is a playable suited connector on the button in three-handed, so I open to 2.5bb rather than limp or fold.

AJ suited is strong enough to 3-bet from SB against a button open; raising builds the pot with a hand that plays well and can isolate against the button.

Q4o is far too weak to call 800 more against a 3-bet with two active opponents; folding preserves 9900 chips for better spots.

76s is too weak to continue against a large 9bb three-bet; the price and likely value-heavy range make folding the higher-EV play.
