Hold'em table

Holding 73 offsuit on the button is well outside any reasonable opening range, so folding is the standard play.

KQs is a premium heads-up hand with strong equity against the big blind's range; raising builds the pot and takes initiative rather than just limping.

JTo is a reasonable defend versus a small-blind 3x open, and calling 200 into 400 gives decent pot odds with position postflop.

The board pairs itself (5-5), so virtually every hand that called my preflop raise (any pocket pair, J-x, 5-x) already has two pair or better, while my K-high only beats rare unpaired no-ace hands. Checking keeps the pot small with a hand that has little showdown value and folds cheaply to aggression.

I have jacks and fives on a paired flop after the small blind checked. A two-thirds pot bet gets value from worse jacks and draws while keeping the pot manageable.

My Kc-Qc missed the Js-5c-5d flop completely (king-high), and seat_3's flop lead after flatting my preflop raise strongly suggests a jack, five, or decent pair. Calling 400 into that range with almost no equity isn't profitable.

J7s is a playable button open in a 3-handed game with fold equity against the blinds; a standard 3x raise builds the pot with a suited hand and initiative.

A5o is too weak to continue out of position against a button raise with the big blind still to act, so folding avoids a dominated, poorly playable spot.

54 offsuit is too weak to defend out of position against a 3bb open.

Pocket eights is a strong hand three-handed on the button, so I open-raise to 3x rather than flat the big blind and give the blinds a cheap flop.

T6o is too weak to defend out of position against a button raise.

32o is the worst hand and faces a 3x button raise with another player still to act; calling 200 into a weak spot loses long-term.

Fold 43s on the button as it is slightly too weak to reliably open even in 3-handed play.

On the button with 76o in a 3-handed game, a standard raise pressures the blinds to fold and gives me position if called; calling is marginal and folding gives up steal equity.

34o is too weak to continue from the small blind against a button open to 3bb. Folding avoids putting more chips in with a dominated offsuit hand.

Holding 9h5d in the big blind against a 3x open from the button is too weak to defend out of position, making an easy fold.

T2o is too weak to open even on the button, so I fold rather than invest chips with a dominated offsuit hand.

Q4o is too weak to play out of position blind versus blind, so folding is the standard play.
