Hold'em table

K2o is too weak to open profitably even from the button in a 3-handed game.

Heads-up after the button folds, I only need 50 more to call into a 3:1 pot, and the big blind's range is wide, so completing with 53o is better than surrendering my blind.

T5s is too weak to raise for value against a limp, and I can see the flop for free in the big blind. Checking keeps the pot small and realizes the hand's suited equity.

I hold 5-high with no real draw on a Q-8-4 board, so betting is a pure bluff with poor fold equity against a wide big-blind checking range. Checking costs nothing and I can easily fold to any aggression.

Ten-five has no pair and no real draw on Q-8-4, so a flop stab has little equity if called. Checking keeps the pot small and realizes whatever free equity the turn gives.

Ten-high has no pair or draw on Q848, so there is no value in betting. Checking keeps the pot small and sees a free river.

The river ace gives me ace-high, which beats every no-pair hand except AK. Betting would only fold out worse high-card hands while getting called by any pair, so checking to realize showdown value is clearly best.

Ten-high has no showdown value and no credible bluff on this paired ace-high board, so checking back is the lowest-variance line.

T6s is a standard button open three-handed; raising 2.5x builds the pot with position and fold equity rather than limping into a multiway pot.

Js8s is suited and playable versus a wide button open in three-handed poker, and calling 200 into this pot is priced reasonably enough to see a flop out of position.

Getting 4:1 immediate pot odds closing the action with a pocket pair, calling to set-mine is clearly +EV.

Js8s is two overcards with no pair or draw on a dry 752 flop, and I am first to act into the preflop raiser. Checking is the disciplined play rather than leading with air.

Flopped top set on a dry board; checking to the preflop aggressor in position to let them continuation-bet.

I whiffed the flop with T6s; both opponents checked, so taking a free turn card is the best value-neutral line.

Js8s is air on a paired, dry turn multiway and out of position. Checking keeps the pot small rather than bluffing into two opponents who can easily have a pair or the five.

Turned a full house with sevens full of fives. Betting for value after the flop checked through.

Ten-six offsuit has no pair, no real draw, and missed the paired board entirely; calling 450 into a small pot against a late-position stab would burn chips.

Js8s is just two overcards on a paired board with no flush or straight draw, and calling 450 into 1200 needs more equity than this hand has against a turn bet.

J4s is playable from the button in three-handed poker with position and fold equity, so a small open is better than calling or folding.

Holding 8c 4s out of position against a button raise is an easy fold.

Opening on the button with T9o to steal the blinds and realize positional advantage.

AKo is a premium holding; I 3-bet for value and to isolate the button opener rather than flatting out of position with the BB still to act.

85o is far too weak to continue against a button open and a small-blind 3-bet. Folding avoids putting more chips in with a dominated offsuit hand.

T9 offsuit is too weak to continue against a 3-bet to 7bb out of position or in position without suited equity.

Q7o is a marginal but playable button open in 3-handed play; a standard 2.5x raise leverages position and fold equity without risking much.

J5s is too weak to continue out of position from the small blind against a button open, especially with the big blind still to act. Folding avoids a dominated, low-equity spot.

AQ suited is a premier 3-handed holding; 3-betting from the big blind for value against the button open.

Q7 offsuit is far too weak to call a 3-bet from the big blind; I'm dominated by most of his value range and 4-bet bluffing here would just burn chips. Folding preserves my stack for better spots.

Q6 offsuit is too weak and poorly playable to open even from the button, so folding preserves chips.

In a blind-vs-blind spot after the button folds, raising with suited connectors/gappers like J5s puts pressure on the big blind and takes initiative.

Q3s is near the bottom of a defend range but the SB min-raise is wide, and calling 200 into a 400 pot needs only ~33% equity, which this suited hand has against that range. Three-betting is too thin and folding is too tight at this price.

As the preflop aggressor on an Ace-high dry board, a one-third pot continuation bet exerts strong range pressure against the big blind's wide defense range.

I only have queen-high with no pair and just backdoor draws on an ace-high board against the preflop raiser's c-bet. Calling or bluff-raising here loses money long-term, so folding is the cheapest and best line.
