Hold'em table

78o is playable enough from the button in three-handed poker to open for a small raise and take the initiative rather than limp or fold.

T5 offsuit is far too weak to defend the small blind against a 2.5x button raise with the big blind still behind and me out of position. Folding is clearly the highest-EV play.

Getting favorable pot odds (150 to call into a 400 pot) with a pocket pair closing preflop action against a button open.

I check my weak underpair out of position against the preflop raiser on an Ace-high board.

I have no pair and no draw on an ace-high flop, so checking has little value. A small c-bet uses my preflop initiative and can fold out missed hands cheaply.

Holding an underpair on an Ace-high board facing a continuation bet, we have minimal equity and should fold.

JTo is a solid button open three-handed; raising to 3x builds the pot with initiative and fold equity rather than limping into a multiway flop.

Folding 96o in the small blind facing an open raise from the button.

K5 offsuit is too weak to continue against a button open; it is dominated often and plays poorly postflop, so folding is the highest-EV option.

Folding 65 offsuit on the button as it is too weak to open profitably even 3-handed.

Button folded, so this is heads-up versus the big blind with ace-high. A small raise takes the initiative and builds the pot with a playable hand rather than just completing out of position.

K2o is dominated by the SB's raising range and plays poorly out of position with a weak kicker; calling 200 more into a small pot has bad implied odds, so folding is standard.

Q8s is a playable suited queen on the button in a three-handed game, so I open to 2.5bb rather than limp or fold.

J9s out of position against a button raise with the big blind still to act is too weak to call or three-bet profitably; folding preserves chips for better spots.

T2o is far too weak to defend out of position against a button raise.

I'm on the button in a 3-handed game with a playable but weak hand; a standard small open applies pressure on the blinds and lets me win cheaply or fold to serious resistance.

Q7o is too weak to call an open raise out of position against the button with the big blind left to act.

95 offsuit is too weak to defend out of position against a button open, so folding is the clear choice.

King-five suited is a standard opening raise on the button in 3-handed play to steal blinds and realize equity in position.

Q8 suited is too weak to continue out of position against a button open, where it is often dominated and has poor realization. Folding preserves chips in a marginal spot.
