Hold'em table

Button folded, so A9o is ahead of a random big-blind range and should take the initiative rather than limp. A raise to 300 builds the pot and can win it immediately.

65 offsuit is too weak to defend against a 3bb open raise from the small blind.

T3o is too weak to open even on the button in a three-handed pot, and folding costs nothing since I have no blind invested.

A7s is well ahead of a typical BB range in blind vs blind play, so raising to 300 for value and initiative is standard.

8s4s is far too weak to defend against a 3x raise even in position, and heads-up I still have no fold equity edge worth calling 200 more.

Holding pocket Queens on the button in 3-handed play is a premium hand; opening with a standard 2.5bb raise to build the pot and take initiative.

42s is one of the weakest hands in the deck, and calling 200 more out of position against a button raise has poor implied odds. Folding is clearly the best play.

84o is too weak to call a button open; folding avoids putting more chips in with a dominated, unplayable hand.

95 offsuit has only ~33% equity against two random hands, below the 40% needed to call 100 into a 150 pot, and it plays poorly postflop even in position. Folding is the highest-EV line.

Button folded, but T6o is too weak to complete or raise out of position against the big blind. Folding saves the rest of the stack for better spots.

96o is too weak to call or open from the button against two live blinds; folding avoids a negative-EV spot.

63o is far too weak to complete or raise from the small blind out of position.

Opening pocket sixes on the button is standard in 3-handed play to build the pot and take initiative.

Nine-two offsuit has almost no equity against a button raise, and the big blind still has to act behind me. Calling 200 more with such a weak hand is clearly -EV, so folding is correct.

J5o is too weak to defend the big blind against a button open; folding saves chips versus a hand with poor equity and little postflop playability.
