Hold'em table

5s3s on the button in a 3-handed game is a marginal hand; while suited connectors can be opened, 53s is weak enough that folding against unknown opponents at 100bb is a reasonable, low-variance choice.

Seat 1 folded, leaving a heads-up pot. My Q♠s is a playable hand but not strong enough to raise from the small blind, so I call the 50 to keep the pot small and see a flop.

Holding 64 suited in the big blind against an SB limp, checking to see a free flop in position is standard and realizes our equity well.

I have a backdoor flush draw and a queen high, but the board is dry and I'm in position. Checking allows me to control the pot and see a free card while keeping the opponent's bluff frequency in play.

I hold third pair with a weak kicker in position in a limped pot. Checking back controls the pot size and realizes showdown value safely.

I have middle pair with a backdoor flush draw but no made flush or straight. Checking keeps the pot small and avoids building a big pot with a marginal hand on a wet board.

I have bottom pair with weak kicker on a coordinated board; checking behind controls the pot and allows me to see the river safely.

The board is a scary, high-card-heavy river with no clear made hand for me; checking preserves my stack and lets me realize equity or induce a bluff without risking more chips.

I have showdown value with a pair of sixes beating all unpaired hands, and a bet would only get called by better hands.

I hold J-2 offsuit, a very weak hand, and I am in the big blind position facing a raise from the small blind. Folding avoids investing more chips with poor equity.

75o is too weak to complete or raise from the small blind out of position against the big blind.

Opening with a premium hand (AKs) on the button with a standard 2.5bb raise.

J5 offsuit in the small blind facing a 2.5x button open is a clear fold; it plays poorly out of position and is dominated by the opener's range.

I hold Qc4h, a weak offsuit hand. Seat 3 opened to 250 and seat 1 folded, leaving me to decide against a strong range. The pot odds do not justify calling 150 more with such a marginal holding, so folding is the correct play.

4-3 offsuit on the button in a 3-handed game is well below a reasonable opening range; folding avoids playing a dominated, weak hand out of position postflop against two live blinds.

Calling the 50 chip small blind with 9c Qc is a low-cost way to see a flop and play position, since seat_1 folded and the pot already has 150 chips.

Taking a free flop with 96o in the big blind after the small blind limped.

I have a backdoor flush draw and a gutshot with a queen kicker, but the pot is small and I'm out of position. Checking keeps the pot controlled and lets me see a free turn card without committing more chips.

I hold an open-ended straight draw in position after the small blind checked. A half-pot bet applies pressure to weak holdings while giving me strong equity if called.

Calling keeps me in a speculative hand with backdoor flush and straight possibilities on a board that isn't heavily threatening me yet. Folding would waste my small blind investment, and raising is too risky without a strong made hand.

The board is coordinated with a straight draw and flush possibilities, and my Q-high is vulnerable. Checking keeps the pot controlled and avoids building a big pot with a marginal hand.

Turn completed the nut straight with 6c 9h; betting 300 into 400 to extract value from pairs and flush draws.

Calling the 300 turn raise keeps me in a pot with a backdoor flush draw and a gutshot straight draw, giving me equity without risking my whole stack on a marginal hand. Folding would concede the pot, and raising is too aggressive given my weak holdings and the opponent's prior aggression.

I have a weak Queen-high hand with no pair, and the opponent just raised the turn and called. Checking allows me to see a cheap showdown and potentially induce a bluff or catch a lucky card, while avoiding further investment with a marginal holding.

We rivered a straight on a board of 7s-Ks-8c-5c-8s. Betting half pot targets value from trips (8x) and sticky top pairs while losing minimal if facing rare flushes or boats.

Seat 3's river raise to 500 into a 1500 pot is a large overbet that often represents a strong hand or a bluff; with 9c-Qc I have a backdoor flush draw and some showdown value, so calling is reasonable to see the showdown without risking more chips. Folding would be too weak given the pot odds and my remaining stack.

Calling 100 to see a flop with Td9d in position is reasonable; the pot is 150 and I can play postflop. Folding wastes the blind discount, and raising is unnecessary without a stronger hand.

76 offsuit plays poorly out of position postflop despite the pot odds, making folding the safest play.

Pocket deuces in the big blind facing a button limp; checking takes a free flop to set-mine with position disadvantage, while raising builds a pot out of position with a hand that plays poorly postflop without a set.

Pocket deuces on a paired 4-4-7 board is a weak showdown hand; checking keeps the pot small and lets me see how the button acts, with the option to call a small bet or fold to aggression.

The pot is 250 with a paired board on the flop. I have a middle suited connector and no made hand, so I want to see a cheap turn card and keep the opponent's range wide.

Pocket deuces on 4-7-4-5 is a weak showdown hand that mostly gets called by better; checking keeps the pot small and lets me evaluate a river bet from the button.

The board is paired with a 4 and a 5, giving me a weak 9-high draw with backdoor flush potential. Checking keeps the pot small and avoids building a big pot with a marginal hand against a likely stronger range.

Board 4h 7s 4d 5d Th with 22 gives me a weak two pair (4s and 2s) that loses to any pair above 2s; betting gets no value from worse and folds out nothing better, so I check and realize showdown value against a possible missed hand.

The board is paired with a Ten on the river, and my hand is a weak Ten-high with a Nine kicker. There is no clear value in betting, and checking allows me to potentially split the pot or induce a bluff from seat_1.

Opening with AJo on the button is a standard value raise in 3-handed play.

7-4 offsuit in the small blind facing a 2.5x open from the button is a clear fold; it's a weak, unsuited, unconnected hand that plays poorly out of position.

With 6c9s and a 150 chip call facing a 250 raise, the pot odds and hand strength don't justify continuing preflop.
