Hold'em table

Q2 offsuit is too weak to complete or raise out of position against the big blind, so folding the extra 50 is the lower-variance choice.

AK offsuit is a premium hand on the button, so I open-raise to 3x the big blind to build the pot and take the initiative.

75 offsuit is too weak to defend out of position from the small blind against a 3bb open.

QJo is playable heads-up getting a price; flat the 200 and play in position versus a wide button open rather than bloat the pot out of position.

I have only Q-high with a weak spade backdoor on a K-high board against the preflop raiser, so checking to avoid building a pot with air is best; I can fold to pressure or reassess on later streets.

Top pair, ace kicker on a checked flop. A half-pot bet gets value from worse kings and draws while denying free cards.

95s is slightly too weak to open profitably even on the button in 3-handed play.

Heads-up vs one random hand in position-ish; 83o is too weak to call, but a light 3x raise can take it down or let me fold if 4-bet.

83s is too weak to continue against a 3bb small-blind raise; folding avoids putting more chips in with a dominated, low-equity hand.

On the button three-handed, a min-raise has strong fold equity and position makes even a weak suited-connector-less hand playable; I can release cheaply if either blind plays back.

43 offsuit is too weak to continue against a button open from the small blind, especially with the big blind still to act.

K2o has poor playability and realization out of position against a button open, making it a standard fold despite favorable pot odds.

K7o is a marginal button open in three-handed play, but position and fold equity make a small raise better than calling or folding.

Holding 96 offsuit out of position against a button open is an easy standard fold.

Ace-high with a suited-club possibility defends cheaply against a 2.5x open; folding A3o in position BB is too tight, and calling keeps the pot small with a playable hand.

I have top two pair and can check-raise or let the preflop aggressor bet; checking keeps the pot growing on my terms.

King-high with no pair or draw on an ace-high flop has little showdown value and poor fold equity against a big-blind calling range, so I check back rather than inflate the pot.

I hold trip aces with a 3 kicker on a paired board, near-nuts. I'll check to trap seat_2 and keep the pot growing cheaply.

King-high has no pair or draw on a paired-ace board, and seat_1 has checked twice after calling preflop. Checking is free and keeps a little showdown value against air.

King-high has no pair on a double-paired board, so there is no value in betting. Checking realizes the free showdown against a preflop caller who can easily have an ace or a pair.

A8o is a solid opening hand on the button in 3-handed play, so I open with a standard 2.5x raise.

K3s is far too weak to defend out of position against a 2.5x button raise; the dominated kicker and poor postflop realization beat the suited pot odds.

K7o is too weak to continue out of position against a button open; the price is not good enough once postflop realization is considered.
