Hold'em table

K5 offsuit is strong enough to open on the button three-handed. A modest raise pressures the blinds while keeping the pot manageable.

Q4o from the small blind facing a button open to 2.25bb with the big blind still to act is a weak hand that plays poorly out of position, so folding is the disciplined choice.

A2o has poor playability and reverse implied odds out of position, making it a standard fold facing a button open.

A6 suited-ish offsuit ace on the button in a 3-handed game is playable; calling 100 to win 250 pot is a good price, and raising risks bloating the pot with a marginal hand. Chat is off so no message.

Isolating the button limper from the small blind with a strong broadway holding.

8-5 offsuit plays poorly out of position against a large raise, especially with the button still in the hand.

A6s on the button is a reasonable call getting about 2:1 (300 to win 600) against a small blind raise, with position and an ace-high blocker. A 3-bet with this hand is unnecessary and folding gives up too much equity.

As the preflop aggressor on a dry Ace-high flop, our range has a significant advantage over a limp-caller, making a one-third pot continuation bet effective.

Top pair with the nut-ace kicker... actually two pair (aces and sixes) on A-6-4 is very strong; raising for value against a c-bet range that includes draws and weaker aces.Two pair is well ahead of most of the opponent's range.}

I whiffed the flop with King-high and no real draws; facing a raise on an Ace-high board, folding is standard.

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

Q9 offsuit is strong enough to raise heads-up against the big blind. A modest raise pressures weaker hands without committing too many chips out of position.

Getting 350 into 150 (about 2.3:1) against a small blind raise to 2.5bb, which is a wide range; 9-6 offsuit has some equity and I close the action, so calling is reasonable. Folding is close, but the price is good enough and 3-betting would be too loose.

The ace-high, dry flop favors my preflop raising range. A small continuation bet can pressure the big blind's unpaired hands while risking relatively little.

6-9 offsuit on a T-4-A board has only backdoor draws and no pair. Calling 150 to win 800 needs about 19% equity, but this hand has roughly 10-15% against a small-blind continuation range, so folding is best.

On the button in a three-handed game, 7-6 offsuit is playable as a small opening raise, using position and fold equity.

A2s is a decent hand against a button open to 2.5bb, but playing it out of position against a BB still to act makes a 3-bet marginal. Calling 200 more is cheap, and the suited ace gives good playability.

Q9o realizes poor equity out of position multiway despite getting 4:1 immediate pot odds, making folding the standard play.

Ace-high on a paired 8-8-4 flop heads-up, first to act out of position. A small bet of about half the pot can get folds from hands like unpaired overcards and take the pot, and it also builds a pot when ahead against worse Ax or small pairs. Checking would give up the initiative.

I have a gutshot straight draw and position. Calling 300 into a 900-chip pot lets me continue without committing a large raise.

I have ace-high with a backdoor-free board of 8-8-4-Q, so I only have a weak showdown hand. Checking keeps the pot small and lets me realize my equity against a button caller, and I don't want to bloat the pot with a hand that beats few of the hands that continue.

I have a gutshot straight draw and can take a free river card. Betting risks building a pot against hands that called the flop, so I’ll check behind.

Board is 8h 8c 4c Qd 2d and I have two pair, 8s and 2s, with an ace kicker that plays as the board's high card. That beats most of the button's hands that check back the turn, such as ace-high or small pairs. A small value bet of about 40% of the pot should get called by worse pairs and ace-high while risking little against a queen or a better pair.

Seven-high is unlikely to win at showdown, and this hand has no useful blockers to support a river bluff-raise.

Q8 offsuit on the button in a 3-handed pot is marginal. Folding is safe, but calling or a small raise would also be defensible. I'll fold to avoid playing a weak, dominated hand out of position against two players.

Completing the small blind with a playable connector getting 3 to 1 pot odds against the big blind.

With 6-2 offsuit out of position, I’ll take the free flop rather than build a pot.

I completely missed the flop out of position and have no significant equity, so checking is standard.

The small blind checked a dry flop, and my gutshot gives a small bet some backup equity when called.

I have nine-high with no draw on a Queen-high flop, making an easy fold to the half-pot bet.

Opening K5s on the button in 3-handed play is a standard, profitable steal attempt.

T6 suited is too weak to defend the small blind against a button raise, especially with the big blind still to act.

7s3s is weak, but I'm getting 400 to 150 (about 2.7:1) closing the action against a button min-raise, so calling is reasonable. A 3-bet bluff with this hand isn't needed.}

I have second pair (sevens) with a backdoor flush draw on a dry A-7-2 board, so betting about half the pot for value and protection is reasonable against a button raiser's wide range, and it denies equity to overcards and draws.

I have complete air with king-high and no draw on an Ace-high flop facing a donk bet, making this a clear fold.
