Hold'em table

A small button open uses position and risks little to contest the blinds. T4 suited is marginal, but its suitedness gives it some postflop playability when called.

K3 offsuit is too weak to defend from the small blind against a button open with the big blind still to act.

Q6 offsuit is weak, but the small raise and folded small blind give me a good price to defend the big blind.

Bottom pair has some showdown value, but this connected flop favors the preflop raiser enough that checking is preferable to building the pot.

Top pair with a weak kicker has showdown value but is vulnerable on this connected, two-diamond board. Checking back controls the pot, avoids a difficult check-raise, and protects our checking range.

Bottom pair has some showdown value, and the queen of diamonds gives me a flush draw on a diamond river. With no bet to face, I prefer to check rather than build the pot.

Top pair with a weak kicker has showdown value, but this coordinated, three-diamond board makes betting for value unattractive. Checking keeps the pot small and avoids a check-raise while retaining position on the river.

Bottom pair has some showdown value, but betting is unlikely to get called by worse hands. I’ll check and take the free showdown if offered.

Our pair of tens has showdown value, but few worse hands are likely to call a bet on this coordinated board. Checking avoids paying better pairs, straights, or flushes.

On the button in a three-handed game, 8-7 offsuit is suitable for a small opening raise to leverage position and initiative.

KJo is strong enough to reraise a button min-raise in a three-handed game. Raising also avoids playing a multiway pot out of position.

42 offsuit is far too weak to continue against a raise and a three-bet, especially with the original raiser still to act. Folding avoids committing another 700 chips with poor equity and playability.

87 offsuit performs poorly against a small blind 3-bet, especially with a deep stack and no positional advantage postflop.

K-Q suited is a strong button opening hand in three-handed play. Raising to 2.5 big blinds builds the pot while retaining position.

Seven-five offsuit is too weak to defend against a 2.5bb button raise from the small blind. Poor equity realization out of position and the big blind still to act make calling unprofitable.

J6 offsuit is too weak to defend from the big blind against a button raise at this sizing.

64 offsuit is too weak for a standard button open against two players at 100bb depth. Without evidence that the blinds overfold, folding is preferable to raising or limping.

With AQs heads-up from the small blind after the button folds, I raise for value and initiative. A 3bb total raise is a standard sizing that can win the blind or build a pot with a strong hand.

Against a small-blind open, 9-4 offsuit has enough equity to defend the big blind at this price, especially with position after the flop.

I will make a small continuation bet with two strong overcards and useful backdoor potential, leveraging the preflop range advantage while risking little.

Nine-high has no pair or immediate draw on this flop. Even against a small bet, continuing is unlikely to be profitable.

Button with suited J8 has enough playability to open-raise three-handed. A 2.5bb raise pressures the blinds while keeping risk controlled.

A5 suited is a strong three-bet candidate against a button open, and raising avoids playing a multiway pot out of position.

42 offsuit is far too weak to continue against a raise and a three-bet, especially with the original raiser still to act. Folding avoids investing another 900 chips with poor equity and playability.

J8 suited is too weak to continue versus a large small-blind 3-bet after opening, especially at this depth.

On the button in a three-handed pot, 6♠3♠ is a marginal but playable suited opener. A small raise gives us a chance to win the blinds while keeping the pot manageable.

75 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act. Its poor equity realization out of position makes folding preferable to calling or bluff-raising.

8-high offsuit is too weak to defend against a button open from the big blind at this sizing.
