Hold'em table

Button opening with suited connected 54 has strong playability three-handed and can profitably apply pressure preflop.

2-K offsuit is a weak hand in early position, especially facing a raise to 250 chips. Folding preserves chips and avoids playing a marginal hand out of position against an aggressive opponent.

J8 suited is playable for a cheap call in the BB against a standard raise; not strong enough to 3-bet.

No pair or strong draw on this paired board; check to control pot size and see what the preflop raiser does.

With only a weak gutshot draw and little showdown value on this paired board, checking back realizes equity cheaply.

No pair or strong draw, checking back to control pot size on the turn.

Betting our pair of fives for value against ace-high and smaller pocket pairs while denying free equity to overcards.

I have no pair and no draw on this paired low board, so folding to the turn bet is correct.

Ac9c is a strong hand (ace-high with flush potential). From the button against a big blind and small blind, a 3x raise to 300 (min-raising would be 200, but 300 is better for value) is standard. This builds the pot with a premium hand and puts pressure on the blinds.

2h Ts is a weak offsuit hand facing a 3bb raise; folding is best to avoid marginal spots.

Defend the big blind heads-up versus the button min-raise with J9 suited; it has adequate equity and playability for the price.

Check the medium-strength pair from out of position in the raised pot, keeping the opponent's bluffs and weaker continuations in range while controlling the pot.

I have Ac9c with a flush draw on a JcQh7d flop. Checking keeps the pot small while I assess opponent intent and allows me to realize my equity on future streets. My opponent checked, indicating weakness, so there's no need to bet here.

Our marginal pair has useful showdown value on this paired board, while betting mostly folds worse hands and receives calls from stronger holdings. Checking keeps the opponent's bluffs in range.

I hold Ac9c with a paired board (JcQh7d7s). My hand has limited showdown value against seat_1, and checking allows me to reach showdown cheaply. Since we've both checked through flop and turn, checking again avoids unnecessary risk while keeping the pot manageable.

We have two pair on a passive river line and can value-bet against Qx, 7x, and weaker bluff-catchers. A moderate sizing targets calls while limiting losses against a slow-played strong hand.

Holding Ac9c on a river with Jc7dQh7s5d, I have only an ace-high hand with no flush draw possible. Opponent's river raise of 450 into 650 suggests strength, likely a pair or better. Folding is prudent with only 9 high against an aggressive line.

Button raise with J9o in a 3-handed pot to build initiative; hand has decent playability and folding equity.

Qc5h offsuit is too weak to defend from the small blind against a button open with the big blind still behind.

4-6o is a weak hand with poor equity against seat_3's raise. Folding avoids a marginally profitable confrontation and preserves stack for better opportunities.

K8 offsuit is a marginal button open in this structure; folding avoids playing a weak dominated hand when stack preservation has value.

2-4 offsuit is a weak hand with very poor equity against the big blind. Folding the small blind against a bet avoids throwing more chips at a losing position.

Ace-high suited hand heads-up after button folded; raise for value/isolation against the big blind.

QJs is a strong blind-versus-blind hand and benefits from applying pressure preflop. A 3-bet to 1000 builds initiative while retaining maneuverability.

A7 offsuit is a decent button hand in a 3-handed game; raise to build the pot and take initiative given fold equity against both blinds.

Calling with a pocket pair is profitable at this small button open size, especially with implied odds in a three-handed pot.

Ad6d is a weak hand facing two opponents with a raise to 250 and a call. Folding preserves chips in an unfavorable position where I'm out of position with poor equity.

Checking preserves pot control with a weak underpair on a high, coordinated board while retaining some showdown value.

I raised pre-flop and opponent checked; I have an ace-high with no pair, so a continuation bet here can pick up the pot given my range advantage.

Pocket fours have minimal equity against a continuation bet on this king-high, two-club flop and few profitable turn paths. Folding preserves the stack.
