Hold'em table

Q4 offsuit is too weak to continue out of position for another half blind after the button folds.

A6o is a standard button open in three-handed play; a 2.5bb raise takes the initiative and can win the blinds or continue with the ace.

Facing a button open in a 3-handed game, KJo has strong equity and blocker value; 3-betting out of position allows us to seize the initiative and potentially take down the pot preflop.

8h5s offsuit is a weak hand facing a 3-bet to 9.5bb; folding minimizes losses.

A6o is too weak to continue against a 9.5bb three-bet; calling or four-betting leaves me dominated too often.

T6o is too weak of an offsuit hand to open from the button, making an easy fold.

Heads-up after the button folds, Q9o has solid equity against the BB's range, and raising in position builds the pot and denies a cheap flop rather than limping a hand that is often ahead.

69 offsuit is too weak to continue against a raise, even with position and a cheap price. Folding avoids dominated spots and difficult postflop decisions.

Button folded, so I only need 50 more into 150 with an ace. Completing is the right price out of position; I can fold if the big blind applies pressure.

Holding Q9o in the big blind after the small blind completed, checking to see a free flop with position is standard and solid.

Ace-high with no pair or real draw on a paired flop has some showdown value, so I check out of position rather than bloat a small pot.

I have Queen-high with some showdown equity in position in a limped blind-versus-blind pot, so taking a free turn card is standard.

Ace-high with no pair or draw is too weak to bet out of position into a paired board; checking keeps the pot small and preserves showdown value.

Turned top pair on a paired board after a checked flop; betting for value and protection against draws.

Ace-high with no pair or draw faces a turn bet on a paired queen-high board; not enough equity to continue.

Q8o is a playable button open in three-handed poker; a 2.5bb raise takes the initiative with position and fold equity against the blinds.

Folding 98 offsuit from the small blind against a button open is a clear standard play due to poor playability out of position.

2-6 offsuit has almost no equity or playability against a button raise, and calling 150 more into a 400 pot is unprofitable. Folding is clearly the best option.

K5s is a standard open-raise from the button in 3-handed play to steal blinds and realize equity in position.

T6s is too weak to defend against a 2.5x button raise while out of position; it's dominated by stronger tens and plays poorly postflop, so folding is the highest-EV line.

73s is too weak to continue out of position against a button open; folding avoids a dominated, poorly connected hand.
