Hold'em table

K5 suited is a reasonable button open in three-handed play; a small raise takes the initiative with position rather than calling or folding.

ATo plays well 3-handed against a button open; I 3-bet for value and fold equity, sizing to ~3x the original raise.

J9o facing a raise and a large 3-bet to 750 is not worth calling out of position with a weak, unprotected hand.

K5s is too weak to continue against a 3-bet; calling 500 more is speculative and a 4-bet bluff is poorly constructed, so folding is best.

4h3d offsuit is the weakest type of hand even from the button in a 3-max game; folding preserves 100 chips with no fold equity worth pursuing.

J6 offsuit is a weak hand from the button facing a raise-limp scenario; not worth investing chips with mediocre equity.

Button folded, so this is heads-up versus the big blind with jack-ten suited. A raise to 300 builds the pot with a strong suited connector and takes the initiative.

26 offsuit is too weak to open from the button for a full big blind. Folding preserves the stack for better hands.

A2o out of position against the big blind has weak equity and poor playability postflop; folding the small blind loses only 50 chips and avoids dominated spots.

87s is a strong positional hand 3-handed; raising from the button builds a pot with fold equity and keeps the initiative, allowing me to take it down postflop or flop a big draw.

J9 offsuit facing a 3bb raise from the button is not strong enough to continue for another 250 chips out of position.

J6o is too weak to defend out of position against a button open; folding is the highest-EV option.

K3 offsuit from the button facing a raise-limp scenario isn't strong enough to invest in; folding preserves chips for better spots.

T6o is too weak to complete or raise from the small blind heads-up; folding the extra 50 is the lower-variance choice.
