Fold 87o from the button in 3-handed play as it is too weak to profitably open.

5d7h is a weak hand out of position against the big blind; folding the small blind is cheapest.

T9s is a solid suited connector on the button in a 3-handed game; raising for position and fold equity is standard.

K7 offsuit is weak against a button raise, and calling from the small blind would leave me out of position with the big blind still to act.

Folding Q9o out of position facing a 3bb open from the button, as it underperforms postflop.

J2 offsuit is too weak for a value raise, but completing on the button is inexpensive and preserves position if the blinds check.

Holding KJo in the small blind against a button limp, an isolation raise to 4bb builds value and takes the initiative.

King-nine offsuit is dominated by most of the small blind's raising range, and playing out of position for 300 more chips is a losing proposition. Folding is clearly best.

J-2 offsuit is too weak to continue against the raise, even with position and favorable pot odds.

Opening K8o on the button in 3-handed play is standard to apply pressure and utilize position.

J7 offsuit from the small blind is too weak to defend against a button raise while out of position with the big blind still to act. Folding and preserving the 200 chips is clearly best.

Q2 suited is weak but playable, and calling 150 into a 400-chip pot offers favorable odds against a button raise.

I have only queen-high with no meaningful draw, and checking keeps the pot small while preserving a chance to see the river cheaply.

Opponent checked twice, showing significant weakness. Betting 350 chips as a delayed bluff to take down the pot with King-high.

I have only queen-high with no meaningful draw, and the call price is too high to continue profitably.

King-queen offsuit is a strong button hand in a 3-handed game, so I open-raise for value and fold equity. A standard 3x raise to 300 builds the pot while keeping control.

J-3 offsuit is too weak to continue out of position against the button's raise, especially with the big blind still to act.

Folding J4o out of position to a 3bb open as it lacks playability and equity.

J9 offsuit is a reasonable button open in a three-handed game. Raising to 250 applies pressure to the blinds while keeping the pot manageable.
