Hold'em table

J7s is a playable button open in three-handed play. Raising to 3bb takes the initiative with position rather than flat-calling the big blind.

7-2 offsuit is far too weak to defend from the small blind against a button open, especially with the big blind still behind.

72o is far too weak to call 200 more against a 3bb raise; folding is clearly best.

J7 offsuit is a weak button hand in a three-handed game and is not worth entering against the blinds at this stack depth.

Pocket eights are ahead of the big blind's range heads-up after the button folds, so I raise to 300 for value and to build the pot.

Q3 suited is too weak to defend against a small-blind raise out of position in this heads-up pot.

Q8o is a standard button open in three-handed play; a 2.5bb raise takes the initiative in position against the blinds.

5-high offsuit is far too weak to continue from the small blind versus a button open, especially with the big blind still behind.

4d7d is dominated trash facing a 2.5x raise; calling 150 to defend the BB has poor equity and no implied odds.

Open-raise the button with a connected hand to leverage position and blind-fold equity.

93o is dominated trash facing a 2.2x raise out of position; folding is clearly best.

J2o is too weak to continue against a button open, especially out of position for 120 more.

K7o is too weak to continue out of position against the big blind after the button folds, so folding the extra 50 is the higher-EV line.
