Hold'em table

T5o is too weak to open from the button for a full big blind, so folding preserves chips.

Seat 1 folded, leaving a small blind of 50 and big blind of 100. My hand (4s Qh) is weak offsuit and unlikely to improve enough to justify calling 50 or raising. Folding preserves my 10000 chip stack for better opportunities.

With 6s9h on the button facing a 100 big blind raise, the hand lacks the strength to call or reraise preflop, so folding minimizes expected loss.

Getting 3:1 pot odds in the small blind against only the big blind, calling is cheap and keeps a weak but playable hand in a heads-up pot.

36o is too weak to raise, and checking is free with no bet to call.

With J-high and no pair or draw on a paired board, checking preserves chips and avoids building a pot out of position with a weak hand.

I have no pair, no draw, and no showdown value on a paired board, so checking back is the highest-EV line with a free option.

With J-high and no real equity on a paired board, checking keeps the pot small and avoids risking chips as a bluff into an opponent who has already shown willingness to continue.

Board trips with no kicker or full house for me; checking is free and bluffing this texture has little fold equity.

J-high has no showdown value, but the passive opponent has checked through and may also be weak; betting into a paired board risks chips when any pair or better likely calls.

Board trips with 9-7 kickers means my 3-6 never improves; I can only chop or lose, so a river bet is pure spew. Checking is free and preserves the rare chop.

With 43s on the button, I have good implied odds and position for a cheap 1 BB call; folding is too tight and raising risks too much with a weak suited connector.

K9o is marginal but the price to complete is only 50 into 250, so calling to see a flop is better than folding or bloating the pot out of position.

I am in the big blind with Qd5d and no one has raised, so checking keeps my optionality and lets me see a flop cheaply with this suited hand.

King-high with no pair or draw on A-3-2 has little equity multiway, so checking is the best option.

I have a weak hand with backdoor flush potential but no made hand, and the pot is small with no bets to call. Checking keeps the pot controlled and lets me see a free card while preserving my stack.

I have bottom pair plus backdoor straight and flush equity, and both opponents checked on a dry ace-high flop. A small bet in position can take down the pot or charge worse draws while keeping the risk controlled.

King-high with no pair or draw on an ace-high board is too weak to continue against a flop bet.

My Qd5d is weak on a 3d-Ah-2s flop with a 200 bet facing me; calling is a clear fold and raising is too risky without a made hand or strong draw.

Jack-four offsuit is too weak to open from the button for a full big blind, even three-handed. Folding avoids a dominated, poorly connected hand out of position postflop.

Calling the 50 ante with Kd7h keeps the pot small and avoids building a big pot with a mediocre hand out of position.

The small blind limped and the button folded, so I will raise with a strong ace to isolate and take the initiative. ATo plays well heads-up with position.

7h Kd is a weak offsuit hand facing a 300 chip raise from the big blind; folding preserves my stack against a strong range.

Kd7c is a weak offsuit hand with limited playability, and I'm facing a raise to 100 with only 50 invested by the small blind. Folding preserves my stack against two opponents who have already shown willingness to put chips in.

Button folded, so this is effectively heads-up. Q6o is marginal but getting 3:1 to call, and calling keeps the pot small out of position rather than bloating it with a weak offsuit hand.

J2s is too weak to isolate a limper; checking realizes the free flop with position and suited connectivity.

I have middle pair with a weak kicker on a coordinated board; checking controls the pot and avoids bloating it against a likely range that connects with K-Q-T.

I have an open-ended straight draw on a connected flop and position after a check, so a small semi-bluff builds the pot and can fold out weak hands while I still have strong equity if called.

I have middle pair with Qs on a KQT board; the pot odds are reasonable and raising would likely only get called by better hands, so calling keeps worse hands and draws in.

We have middle pair with a weak kicker on a wet board; checking controls the pot and lets us see opponent's action before committing more chips.

I have only a gutshot and no pair on a wet board after a flop call, so checking realizes my equity without bloating the pot.

I have a marginal pair of queens on a very coordinated board, and with no bet to call I prefer to check and realize showdown rather than risk a raise from straights or better pairs.

I only have a pair of jacks on a K-Q-J-T board where any ace or nine is a straight, so a river bet is unlikely to get called by worse. Checking realizes showdown value for free.

63o is too weak to call or raise from the button in a 3-handed pot, especially with no dead money and both blinds still active.

K2 offsuit is too weak to continue out of position against the big blind after the button folds; folding saves the extra half-blind.
