Hold'em table

75o is too weak to open or limp from the button even three-handed; folding avoids putting chips in with a dominated offsuit hand.

AKs is a premium hand and heads-up against only the big blind, so I raise for value and initiative rather than just completing. A standard 3x open keeps the pot manageable while building it with a hand that dominates their calling range.

Holding 73 offsuit facing a raise from the small blind, this is a clear fold.

Ten-eight suited on the button in a 3-handed game is a standard open-raise; I have position on both blinds and can take the pot down postflop or win it preflop.

A3o is too weak to call out of position against a 3x open with the big blind still to act, and it makes a poor candidate for a 3-bet bluff.

46o is too weak to continue out of position against a button open; folding saves the extra 200.

J7o is too weak to open profitably from the button even three-handed. Folding is standard.

Button folded, so this is SB vs BB. 78o is too weak to limp OOP, but a small raise has fold equity and can take the dead money.

3-5 offsuit is near the bottom of the range and is dominated by most 3x raise hands; calling 200 into a 400 pot with such poor equity and playability loses long-term, so folding is cheapest.

97o is too weak to open first-in from the button against two players still to act; folding avoids a dominated spot when called.

72 offsuit is the worst starting hand; calling 50 more from out of position against the big blind has negative expected value, so folding is clearly best.

KQ suited is a strong 3-handed hand and I have the button, so I open-raise for value and position rather than just calling.

Pocket threes play poorly out of position against a 3x button open with the big blind still to act, making a fold the cleanest play.

Q6 offsuit is too weak to defend out of position against a button open, so folding is the highest-EV option.

K8s is a strong candidate to open from the button in 3-handed play; raising to 2.5bb applies pressure and builds the pot in position.

75 offsuit is too weak to continue against a button open, especially out of position. Folding avoids paying 200 more with a dominated, low-equity hand.

Defending my blind with J6o at good pot odds (150 into 400) in a 3-handed game where the button's range is wide; I have enough equity to see a flop cheaply and can release easily to pressure.

J-6 missed the Q-T-5 flop with no real draw, so checking is free and keeps the pot small against the preflop raiser; I can fold cheaply if pressured.

I hold King-high with backdoor flush and straight draws in position; checking behind takes a free turn card to realize my equity.

I hold only J-high with no draws on a Q-T-9-5 board, so betting would be a pure bluff with no equity against a preflop raiser. Checking keeps the pot small and lets me fold cheaply if seat_3 shows strength.

The turn connects heavily with the big blind's defending range, so taking the free card with our gutshot straight draw in position is the highest expected value line.

King-high has virtually zero showdown value against BB's calling range, which contains many Ax and pairs. Furthermore, the opponent checked via fallback on the river, making a stab highly profitable.

My board pair of queens with a J kicker beats every busted A-high/K-high stab, and I only need ~28% equity (350 into 900). A preflop raiser who checks flop and turn then bets this pairing river has enough air in his line to make calling profitable.
