Hold'em table

Getting 3:1 pot odds, calling 50 to win 150 is profitable with any two cards against a single opponent, even out of position.

57o is a weak hand; checking as big blind keeps the pot small and we can evaluate the flop.

We have bottom pair with a weak kicker and are out of position. Checking avoids building the pot and lets us see the big blind's action.

Seat 2 checked on a dry flop; a small bet can fold out overcards and take the pot. My hand has little showdown value, so I'll apply pressure now.

I have bottom pair with a weak kicker on a ten-high board, and the pot odds don't justify calling with limited improvement potential. Folding preserves my stack for better spots.

AJs is a strong hand on the button in a 3-handed game; raising to 3bb builds the pot and isolates weaker hands.

A5o is a weak, dominated offsuit ace out of position against a button raise with the big blind still to act. Folding avoids playing a marginal hand in the worst position.

Nine-three offsuit is far too weak to call 200 more against a 3bb raise heads-up; folding is clearly best.

K9o on the button in a 3-handed game is strong enough to raise for value and to take initiative. A 3x raise puts pressure on the blinds and can win the pot preflop or set up favorable postflop situations.

Q7s out of position against a button 3x raise is too weak to continue profitably.

Q2 offsuit is a weak hand that plays poorly out of position; calling the button raise would be -EV, so folding preserves my stack.

Holding 63o from SB vs BB, calling would be -EV due to poor equity and positional disadvantage; folding preserves stack for better spots.

On the button with 64s, I open raise to 3bb to pressure the blinds and use my postflop position.

J7o is too weak from the small blind against a button raise with the big blind still to act; folding avoids playing a dominated hand out of position.

KTo out of position against a 3x raise is a marginal spot; calling keeps the pot small with position disadvantage, folding is too tight given odds.

Heads-up with king-high on a dry flop; checking keeps the pot small and avoids building it out of position with a marginal hand.

I have bottom pair with a weak kicker on a paired board, and the pot is small. Checking behind keeps the pot manageable and avoids a potential check-raise that could force me off my marginal hand.

I hold top pair tens with the K-high flush draw on this board; betting the turn builds the pot and charges draws while extracting value from weaker tens, nines, or hearts.

Our two pair, nines and fours, is vulnerable on this paired board with flush and straight draws. We lack the outs to call profitably and have little showdown value, so folding preserves our stack for better spots.

QJo on the button is strong enough to raise for initiative and pressure the blinds; a 3x open can take the pot down preflop or isolate with position.

J9 offsuit is too weak to call a 3x button raise out of position with two players behind. Folding is the profitable play.

96s has decent playability as a suited connector and getting 2.25:1 pot odds from the big blind against a wide button range. Calling and seeing a flop out of position is acceptable given the 3-handed dynamic.

I have bottom pair with a weak kicker and am out of position, so checking is the prudent play to control the pot and see what the preflop raiser does.

I have an open-ended straight draw with QJ on KT and position; betting applies pressure and can take the pot down while building value if I improve.

I have bottom pair with no kicker on a broadway board. The opponent's flop bet after raising preflop signals strength. With poor equity, no draw, and out of position, folding is the best play.
