Hold'em table

QJo is strong enough to open from the button in a three-handed game, and a 2.5bb raise builds the pot while keeping the hand playable postflop.

King-three offsuit is far too weak to defend the small blind against a 2.5x button open, especially with the big blind still behind. Folding avoids bleeding chips with a dominated hand.

52o is a weak hand facing a raise; not worth calling out of position.

Queen-six offsuit is too weak to play even from the button in a 3-handed game; folding preserves chips for better spots.

7-6 offsuit heads-up against BB with button folded is weak enough to just fold rather than complete for a marginal spot.

Q3 offsuit on the button facing a raise-less pot is not worth continuing; folding preserves chips for better spots.

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

J9 offsuit is too weak to defend against a 3x raise from the small blind, especially out of position with a dominated, poorly-realizing hand. Folding is the clear profitable play.

Button in three-handed with suited jack; a small open has fold equity and position if called, which is better than folding a playable steal.

K8s out of position against a button raise with the big blind still to act is too weak to defend profitably; folding avoids a dominated-king spot with poor postflop playability.

T7 offsuit facing a raise with a player still to act after me isn't worth defending; folding is cheap here.

A9s is a strong suited ace on the button in 3-handed play; raising for value and position with a standard 3x open.

KQo is strong enough to 3-bet for value/initiative against a single raise, especially with a player still to act behind me who I want to isolate against.

T2o is far too weak to continue against a button open and a small-blind three-bet. Folding saves the remaining stack for better spots.

J4 offsuit is weak, not worth entering the pot from the button facing a raise-sized call in a 3-handed game where I have no positional edge post-flop against blinds acting first next hand.

73o is too weak to continue even for a half-blind after the button folds. Folding avoids putting more chips in with a dominated offsuit hand.
