Hold'em table

KTs suited is a strong button hand in a 3-handed game; raising for value and position with a playable suited connector-ish hand.

45 offsuit is too weak to continue out of position against a button open; folding avoids a dominated, low-equity spot.

AJ offsuit is strong heads-up against a single raiser; 3-betting builds the pot with a hand that plays well and can isolate the button.

KTs suited has good playability and I have position on the 3-bettor; calling 600 keeps the pot manageable while realizing equity postflop rather than committing 900+ with a hand that's often dominated.

I have the nut flush draw plus an overcard on a wet board; continuing as preflop aggressor with a strong semi-bluff bet builds the pot and can win it outright.

Top pair with position on a K-high flop; villain's 3-bet range often includes AK/KQ which dominates me, so I'll just call and keep the pot small rather than raise or fold.

I hold the nut flush draw (Ad plus three diamonds on board) with an ace-high overcard, giving strong equity; betting applies pressure and builds the pot for a likely river flush.

KJo is a strong button open in three-handed play, so I raise to 2.5bb to take the initiative and fold out weaker hands.

8s3c offsuit is dominated trash facing a 2.5x button raise; even with 150 to call into 400, poor equity realization out of position makes folding clearly best.

8-7 offsuit from the button facing a raise-limp isn't strong enough to continue profitably in a 3-handed pot; folding preserves chips for better spots.

On the button 3-handed, Q7o is within a standard wide opening range; a 3x raise builds the pot in position and applies fold equity against two blinds.

63s is too weak to continue out of position against a button open, especially with the big blind still to act. Folding avoids paying 250 into a dominated spot.

K8 offsuit facing a 3bb raise from the button with SB already folded is a weak spot to continue from the big blind; folding avoids being dominated.

A8o is a standard button open in three-handed play; a 2.5x raise takes the initiative rather than limping.

K2 offsuit facing a raise from the button is not worth defending my small blind investment against a likely stronger range.

QJo is a standard BB defend against a 2.5x button open in a 3-handed game, and I only need to call 150 into a 400 pot. Calling keeps the pot manageable out of position while retaining good equity and playability.

I whiffed the flop with J-Q high against the preflop raiser, so checking is best; I can fold cheaply to a bet or see a free turn.

I have top pair on a relatively dry flop and the big blind checked, so a small c-bet gets value from worse aces and draws while keeping the pot manageable with a weak kicker.

I hold bare jack-high with no real draws on an ace-high board against a preflop raiser who continued betting; calling would need too much equity. Folding now saves chips for better spots.

A8 suited is a decent button hand; raising to isolate and take initiative against limpers.

4s6h is a very weak hand facing a 3x raise from the button with two players behind; folding is clearly best.

Pocket tens is a strong hand heads-up against a button open, so I 3-bet to 1000 to build the pot and take the initiative out of position.
