Hold'em table

6c4h off the button is a weak hand facing a call with two players to act behind; folding is standard and preserves chips.

QJo is strong enough to raise blind versus blind against the big blind's unrestricted range. A 3bb raise builds value and gives the opponent a meaningful price to continue while we are out of position.

Nine-seven suited plays well in position against a small-blind raise, and calling costs only 200 chips.

Top pair with a solid kicker merits a value bet against weaker queens, nines, and draws. Betting two-thirds pot charges the available draws and denies equity to weaker hands.

Middle pair is strong enough to continue against a single flop bet, especially with position. Calling controls the pot while keeping weaker hands and bluffs in.

Top pair with an open-ended straight draw has solid showdown value, but this turn also improves many of the caller's hands. Checking controls the pot and keeps weaker hands and bluffs in their range.

My middle pair has some showdown value, but a turn bet is unlikely to get called by many worse made hands. Checking keeps the pot manageable and lets me reassess on the river.

Top two pair has showdown value, but the river completes diamonds and gives any king or eight a straight. Checking avoids a thin value bet that would struggle to get called by worse.

My pair of nines has some showdown value, and I have no useful blockers to the straights or flushes that could call a river bluff.

A9 offsuit is a clear opening raise on the button three-handed. Raising to 2.5 big blinds pressures the blinds while leveraging position if called.

A4 offsuit has an ace blocker and is strong enough to occasionally three-bet against a button open. Raising also avoids playing a weak offsuit hand out of position in a multiway pot.

QTo is a marginal hand facing a 9.5bb 3-bet out of position with two opponents; folding is clearly better than calling a large pot-committed range.

A9 offsuit is a marginal defend against this sizable small-blind three-bet and is often dominated by stronger aces. Without evidence of excessive aggression, folding is preferable to calling or bluff four-betting.

T7 offsuit is a marginal but playable button open three-handed. Raising gives me a chance to win the blinds and lets me play in position if called.

King-five offsuit is too weak to continue against a 2.5x button raise with a player still behind. Folding is the profitable play.

65 offsuit is a marginal defense against a 2.5bb button raise and realizes equity poorly out of position. Without evidence that the opener is especially loose or exploitable, I fold.

With the button folded, 65 suited is a reasonable blind-versus-blind steal and retains good playability when called. Raising to 3bb pressures the big blind while keeping the investment modest.

Nine-three offsuit is too weak to defend against a three-big-blind raise, even with position after the flop.

K6 offsuit is a reasonable button open three-handed, with position and a king blocker. A small raise pressures the blinds while limiting investment with a marginal hand.

A-J suited is strong enough to three-bet a button open from the small blind. Raising to 950 applies pressure and avoids inviting the big blind in cheaply.

5s8d is a weak hand facing a 9.5bb 3-bet; folding is clearly best.

K6 offsuit is too weak to defend against this large small-blind three-bet, even in position. Its domination risk and poor playability favor folding over calling or bluff-raising.

Seven-three offsuit is too weak to open profitably from the button against two live blinds.

A4s heads-up after a fold is worth an ISO raise from the SB; folding is too tight and calling leaves a weak range OOP.

AQ offsuit is a strong value three-bet against a small-blind opening range. Raising to 1,000 builds the pot with a likely equity advantage while preserving our postflop positional advantage.

A4o is dominated against a 3-bet range; calling 700 more out of position with a weak ace is -EV.
