Hold'em table

2-6 offsuit is one of the worst hands; folding on the button against two players is standard.

AKs is a premium hand heads-up vs BB after button folded; raise for value to build pot and isolate.

Holding 2d5h, an offsuit trash hand facing a 250-chip call with 3 players, folding is the disciplined play rather than investing more chips out of position.

T4 offsuit is a weak button hand facing a raise-sized call; folding preserves chips for better spots.

Heads-up against the big blind for only 50 chips, and 3-5 suited has some playability, so completing is a cheap, reasonable price to see a flop.

Suited-connector-ish 6d7c is fine to see a free flop in position heads-up; no need to inflate the pot preflop.

I have a pair of fives on a K-8-5 board, a medium-strength hand, so I'll check to take a free card rather than bloat the pot.

I have an open-ended straight draw (4/5) with a free check available heads-up; seeing a free turn card is the highest-EV line at this pot size.

I hold a pair of fives on a board with an unpaired king, queen, and eight, and nothing is owed, so checking keeps the pot small and avoids bloating it with a weak hand.

I have only a gutshot-less 6-high with two checks behind; no value or fold equity worth betting. Checking keeps the pot small.

With a pair of fives on a board that has been checked through, checking is the safe choice and avoids bloating a pot where I likely have the best hand but little to gain from betting.

I have only 7-high on the river with no betting anywhere; checking is free and a bluff would rarely fold a K/Q/J. Avoid losing more chips.

On the button with J4 offsuit facing only a 100-chip completion, calling is cheap and playable in position against two blinds.

I can see the flop for free with K3 suited; no need to raise a speculative hand here.

K-high with weak backdoor draw on a paired board; no reason to bet, check to control pot size.

I hold three 4s on a 4-4-9 board, a very strong hand, so I bet for value to build the pot while the big blind has shown weakness by checking.

K-high with a backdoor flush draw on a paired board facing a bet has little equity or fold equity; folding is cheap and preserves chips.

8-3 offsuit is one of the worst hands; folding from the button against two blinds is the cheapest line.

4h2s is a weak offsuit hand with button already folded; not worth completing against the big blind out of position.

83o is a weak hand from the button with no action to exploit; folding avoids unnecessary investment.

Completing the small blind for 50 more chips with J6 offsuit is a cheap way to see a flop heads-up against the big blind, since the button has folded.

Weak 5-7 off-suit heads-up; I'm already in the BB with no extra cost, so I check and see a cheap flop rather than fold or inflate with trash.

I hold 6-high with no pair on an A-J-2 board; checking is free and keeps the pot small, and the legal actions show to_call is 0, so checking is the sensible line over a bluff raise into the big blind.

I have 75-high on a dry board heads-up; checking is free and I can fold to pressure or take a cheap card.

I hold a pair of jacks on a turn board with no bet to call, so checking keeps the pot small and lets me see whether seat_1 bets.

I hold 5-high with no showdown value; opponent checked flop and turn, so a small stab at the 200-chip pot is a cheap bluff with fold equity.

I have jack pair with a 6-high kicker, which is good enough to continue against a single turn bet of 150 into a 200 pot, since calling 150 into a 500 pot is a reasonable price. Raising would risk more chips against a likely ace or stronger hand.

Pair of jacks on a board with a possible straight or flush draw runout is a medium-strength hand that's best checked for showdown value rather than bloated by a bet into a player who raised the turn.

My 5c pairs the board for fives, likely good against a checked-back missed draw; a small river bet can get called by ace-high or worse pairs.

I hold a pair of jacks, and calling 150 into a 650 pot needs about 19% equity, which a jack-high pair plausibly clears against a two-barrel betting range. Folding would give up a decent chance to win the pot.

Holding 10-2 offsuit on the button, calling the 100-chip completion is a cheap way to see the flop in a 3-handed pot, though folding is also reasonable given the weak hand.

54s in the small blind; completing for 50 is cheap and keeps a playable suited hand with position on the big blind.

Everyone limped and I'm BB with Q9o, checking for free to see the flop.

I have 5-high with no draws on a JK K board; checking is the only sensible option and I can fold to aggression.

Board is King-high paired with a flush draw out there; I have only a gutshot/backdoor with Qs9h, no equity to bet, so checking behind is best in this multiway pot.

I have T-high with no pair on a K-K-J board and no bet to call, so checking keeps the pot small and sees the next card for free.

The board shows four kings, so my best five cards are the board itself (KKKKJ); nearly every holding ties, so betting only risks losing chips with no way to win more. Checking is optimal.

Board is Js Ks Kd Kc, I only have Q9 with no pair, no need to bluff into a paired board with two checks ahead of me; check and see river for free.

I hold T-2 with no pair against a board of J-K-K-K, so I have no showdown value. Checking is free and keeps the pot small.

I have only 5-high with no draw; the board has trip kings so my hand is hopeless. Check and fold to any bet.

Board is K-K-K-J-8; my Q9 gives trip kings with Q,J kickers, likely ahead of many random holdings after a checked-down hand, so a small value bet extracts chips from weaker kickers while limiting risk against an ace or king.

I hold three kings with a Jack-Ten kicker, which is strong against a small 100-chip river bet, so calling keeps me in and captures value without bloating the pot.

I hold 5-high with the board KKK; any opponent holding an ace, jack, or better kicker wins, and the river bet-call suggests showdown strength. Folding costs nothing more.
