Hold'em table

Pocket pair on button, raise for value and position; small pair plays well heads-up/multiway with a raise to build pot and take initiative.

8c4d is a weak offsuit hand. Calling 250 out of position against a button raise, with the big blind still left to act, is a losing play, so I fold.

A5s is a premier 3-bet candidate from the big blind against a button open, offering strong blocker value and postflop playability.

9-6 offsuit is a weak hand out of position postflop against two opponents, so calling 100 to enter the pot isn't worth it. Folding costs nothing on the button.

J8s is a strong suited connector well ahead of random holdings in a blind-versus-blind spot, making an open-raise to 3bb standard.

3-2 offsuit facing a 3x raise heads-up from BB is a clear fold; not enough equity to continue.

J8o is on the bottom edge of playable opening hands on the button 3-handed, making fold the cleaner, standard play.

With the button folded, I'm effectively heads-up against the big blind with a suited-ish Ace; raising to isolate and build the pot with a decent hand.

4d9d is a weak offsuit-ish hand facing a 3x raise from the small blind; calling 200 more out of position with a marginal hand is roughly break-even at best, so I fold.

Weak offsuit 9-6 from the button facing a raise-free pot isn't worth entering; folding preserves chips for better spots.

Heads-up against the big blind after the button folded, A6o is a strong enough hand to raise for value and to take the initiative from the small blind.

Facing a 3bb open from the small blind, J4s is slightly too weak to profitably defend despite having position postflop.

A6 suited on the button in a 3-handed game is a solid raising hand, and a 3x open takes advantage of position against the blinds.

Facing a 3bb button open from the small blind with QJo, calling out of position is -EV and 3-betting is too loose, so folding is standard.

Weak offsuit low cards facing a 3x raise from the button; not worth continuing out of position.

54 offsuit is too weak to open even from the button in 3-handed play.

9-4 offsuit is too weak to continue even heads-up against the big blind; folding preserves chips.
