Hold'em table

J9s is a solid suited connector to open from the button 3-handed; a standard 3x raise builds the pot with position and can win blinds immediately.

K4 offsuit is weak against a 3x raise; folding is correct given poor equity and position.

K3 offsuit is too weak to continue out of position against a button open, so folding is the highest-EV option.

K7 offsuit is a weak hand to open from first-to-act position in a 3-handed pot; folding is standard here.

53 offsuit is too weak to complete from the small blind after the button folds, so I take the free fold rather than play a dominated hand out of position.

Pocket deuces are a standard button open in three-handed play; a raise to 300 takes the initiative with position and can win the blinds or set up a cheap set mine.

Pocket tens is a strong hand heads-up after SB folded; 3-betting builds the pot and isolates the button while charging a premium if called.

Pocket deuces have poor 4-bet value but enough implied odds to call a 9bb 3-bet at 100bb and set-mine.

I flopped a set of tens on a Q-T-6 board; betting sizably to build the pot and charge any flush-draw or top-pair hands.

Pocket deuces are an underpair with no draw on Q-T-6, and a 1200 flop bet is too large to continue with so little equity.

Button folded, effectively heads-up vs BB; Q7 suited is playable and I'll raise to apply pressure and build the pot.

2-5 offsuit is too weak to continue against a small-blind raise to 3bb, even heads-up. Folding avoids putting more chips in with a dominated, unconnected hand.

Weak offsuit hand (4-9) with no fold equity leverage; not worth investing chips preflop.

Q5o is too weak to complete out of position against the big blind after the button folds, so I give up the small blind rather than invest more.

On the button with K2s I open to 2.5bb to steal the blinds; the suited king has enough playability in three-handed to raise rather than fold.

T4o is a very weak hand out of position facing a 2.5x raise from the button; folding avoids losing more chips with minimal equity.

9-5 offsuit facing a raise is a clear fold; not worth defending with such a weak hand.
