Hold'em table

Nine-four offsuit is too weak to open from the button even three-handed.

Heads up against only the big blind, 79o has reasonable equity and I only need 50 more to see a flop into a 150 pot, so folding is too tight and raising risks bloating a marginal hand.

Jack-ten suited is strong heads-up in position against a completed small blind, so I raise to 4bb to build the pot and take the initiative.

Seven-nine offsuit is far too weak to continue against a preflop raise to 4x while out of position, especially having just limped. Folding minimizes losses with minimal equity.

J6o is too weak to play out of position against the big blind, so I fold rather than invest more.

J9o is playable as a button open in three-handed poker, so I raise to 2.5bb to steal the blinds rather than limp or fold.

Holding 4d 2h in the small blind facing an open raise is an easy standard fold.

A3 offsuit is dominated by better aces and has poor equity realization out of position against a button raise, so folding is the clean play.

K7s is well within standard opening range from the button in 3-handed play. Raising to 2.5bb to leverage position.

5-6 offsuit is far too weak to call a 2.5x button raise from the small blind, especially with the big blind still to act and poor postflop position. Folding preserves chips for better spots.

Jack-four offsuit is too weak to defend the big blind against a button open, so folding is the highest-EV option.

Nine-deuce offsuit is far too weak to call even at good pot odds, and the nine is often dominated while the deuce contributes little. Folding on the button preserves chips for a better spot.

Q7o is too weak to complete out of position against the big blind after the button folds, so I give up the small blind rather than invest more.

A7 suited is a standard button open in three-handed play, so I raise to 2.5bb to take the initiative and fold out weaker hands.

92s is too weak to defend out of position against a button open.

65 offsuit flops poorly and plays badly out of position against a button raise; calling 150 more for a weak, hard-to-play hand loses more than it makes. Folding preserves chips for better spots.
