Hold'em table

ATo is a solid button open; a 3bb raise builds the pot and takes initiative before the blinds act.

5-3 offsuit in the small blind against a 3x button raise with the big blind still to act is a trivial fold; calling 250 more out of position with almost no equity or playability just burns chips.

K6o is too weak to defend out of position against a full 3bb open from the button.

Holding 32 offsuit out of position against the big blind is an easy fold despite getting 3:1 odds.

K2o is too weak to open from the button even in 3-handed play.

Button folded, so this is heads-up versus the big blind with a pocket pair. A small raise takes the initiative and builds the pot with a hand that plays well.

Q2o is dominated too often against a 3x raise and plays poorly out of position postflop; the marginal pot odds don't justify defending such a weak hand.

Button open with suited 35s: position and fold equity make a small raise better than folding a playable speculative hand in a three-handed pot.

AKo is a premium hand; I 3-bet for value against the button's open, sizing around 3x to apply pressure with the big blind still to act.

Facing a raise from the button and a three-bet from the small blind, A5s is out of position and best folded.

35s is too weak to continue against an 8bb three-bet; calling 550 more is not justified by equity or playability.

K4o is well within a 3-handed button opening range; raising 3x builds the pot with position and fold equity rather than limping into a contested flop.

A8s is well ahead of a wide 3-handed button opening range, so 3-betting to 10bb takes initiative and denies equity out of position.

KQo is too often dominated by a 10bb small-blind three-bet, and the button can still four-bet behind, so folding the remaining 9bb is the higher-EV line.

K4 offsuit is far too weak to continue against a 3-bet to 1000; I'm dominated by any king and crushed by a strong reraising range, so folding and saving 700 chips is clearly best.

Holding 93o on the button is too weak to open raise even in a 3-handed game.

KJo is ahead of a random big-blind range heads-up after the button folds, so a standard 3bb raise builds the pot and takes the initiative rather than flatting the extra 50.

K6 offsuit is dominated by the small blind's raising range and out of position; calling 200 more to chase a weak king isn't profitable. Folding preserves chips for better spots.
