Hold'em table

87o is slightly too weak to open profitably from the button in a 3-handed game without an ante.

KJs is strong heads-up from the SB after the button folds; raising builds the pot with position and applies pressure to the BB.

The big blind gets a favorable price to defend against a likely wide small-blind opening range, and calling closes the action.

I missed the T-high flop with two clubs and KJ-high only; checking keeps the pot small and avoids building it out of position against the big blind's caller range.

I have a weak pair with a poor kicker, so betting is unlikely to get called by worse often enough. Checking keeps the pot small and preserves showdown value.

Villain called a raise then checked the flop twice, suggesting weakness; a half-pot turn stab with K-high can take down the 500 pot cheaply, and I can fold if raised.

I have two pair, which is strong enough to continue against this turn bet, but calling keeps weaker hands and bluffs in while avoiding an unnecessary raise into a stronger hand.

I hold only king-high on a coordinated board, so I have no value and little showdown hope; checking keeps the pot free rather than bluffing into an opponent who called a turn bet showing strength.

I have two pair, but the river completes a possible 2–6 straight. After the turn bet and river check, checking back preserves showdown value without risking a raise or value-owning myself.

3-7 offsuit is one of the worst hands in hold'em, and I'm out of position against two players for a full BB. Folding is clearly optimal.

Q8 offsuit is playable heads-up against the big blind, and completing cheaply keeps the pot manageable.

KJo has substantial equity and position advantage against an SB completing range, making an isolation raise to 3.5bb profitable.

Q8 offsuit is too weak to continue out of position against a sizable raise; the call price does not make up for its poor playability.

On the button in a three-handed game, Q6 offsuit is playable as an open-raise. A modest raise applies pressure to the blinds while keeping the pot manageable.

J9o is too weak to defend out of position against a button open with the big blind still to act.

Nine-four offsuit is far too weak to defend against a 2.5x button raise even at 150 to call; folding preserves chips for better spots.

Q5o is too weak to profitably open from the button, even in 3-handed play.

Pocket queens on the button is a premium hand; a standard 3x open builds the pot while retaining position and fold equity.

J♣3♣ is too weak to defend from the small blind against a button raise, especially out of position with the big blind still to act.

K8o is too weak to profitably defend out of position against a 3x open from the button.

6-4 offsuit is too weak to open profitably from the button here, and limping gives up the initiative with a poor hand.

T5s is too weak out of position in a blind versus blind battle to justify completing or raising.
