Hold'em table

K5o is too weak to profitably open from the button in a standard 3-handed structure.

Q4o is too weak to complete from the small blind out of position against the big blind, so folding avoids a dominated, hard-to-play hand.

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

85o is too weak to defend out of position against a button open.

T6 offsuit is too weak to open even from the button three-handed with no reads on the blinds, so I'll fold and wait for a better spot.

In a blind-vs-blind situation after the button folded, raising to 300 with Q9o applies pressure and takes the initiative out of position.

96 offsuit is too weak to continue against a small-blind raise, even with position. Folding avoids putting more chips in with a dominated, low-equity hand.

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

Button folded, so I am heads-up with the big blind and only 50 more to call into 150. Ace-deuce offsuit has enough equity against a random hand to complete rather than fold or inflate the pot out of position.

Q9o out of position against one limper is a marginal hand; checking keeps the pot small with a free flop rather than building it with a weak holding.

I have only the nut kicker on a paired board and no real draw, so checking keeps the pot small and realizes showdown value instead of getting called mainly by better hands.

I hold Q-high with no pair on a paired board; checking keeps the pot small and free. I can reassess on later streets.

Ace-high has some showdown value on a paired board, and checking is free with no draw or made hand worth betting.

The turn queen gives me top two pair (queens and eights), and my opponent has shown a fully passive limp-check-check line, so I bet around three-quarters pot for value while charging any club draws.

Ace-high with no pair and no draw is well behind a turn bet, and the price does not justify continuing.

Q8o is playable from the button in three-handed poker with position, so a small open is better than limping or folding.

Facing only a 2.5x raise, I'm getting roughly 3:1 with a playable connector. I'll peel one flop in position-neutral spot and continue only with strong flops, folding to pressure otherwise.

Holding 62o out of position multiway is an easy fold despite decent pot odds.

I have 9-high with no real equity on this Q-high flop against the preflop raiser, so I'll check and fold to pressure rather than donk into the aggressor with air.

I have top pair on a dry board after the small blind checked, so a small value bet builds the pot and denies a free card.

I have 9-high with only backdoor draws on a Q-high board against a preflop raiser's bet; calling needs ~23% equity I don't have, and raising with no fold equity certainty is spew. Folding is clearly best.

K5s is a standard button open three-handed: position plus suited king-high playability makes raising more profitable than calling or folding. Raising to 3x applies pressure and builds the pot when I connect.

Folding T6s out of position in the small blind facing a 3bb open from the button.

73s is too weak to defend out of position against a button open to 3bb; folding avoids a dominated, speculative spot.
