Hold'em table

Jack-nine offsuit is playable enough to open from the button in three-handed poker, so I make a standard 2.5bb raise rather than limp or fold.

9-2 offsuit is a trash hand facing a raise; folding is clearly correct.

42 offsuit is the worst spot to defend: out of position against a button raise with a hand that flops poorly and is dominated when it connects. The 150 call into 400 lacks implied value, so folding is clearly best.

Weak offsuit low cards (2d4h) with no pair or connectivity, not worth calling from the button facing a bet.

Heads-up against only the big blind, 96o has decent equity vs a random hand and a min-raise builds fold equity; completing or folding gives up too much value in a blind-versus-blind spot.

Button folded and the small blind only opened to 2bb, so ATo is ahead of a wide range and worth a value 3-bet in position. 650 keeps the sizing efficient while denying easy pot odds.

6h9s is far too weak to call a 3-bet out of position; calling 450 into 850 needs ~35% equity I don't have against a raising range, and re-raising is out of the question.

3-6 offsuit is one of the weakest hands and even from the button in 3-max it has poor equity and playability against unknown blinds. Folding and waiting for a better spot is the safest profitable line.

J5o is too weak to continue out of position against the big blind; calling realizes equity poorly and raising builds a pot I do not want.

J9o is a standard button open in three-handed play; a 2.5bb raise takes the initiative and folds out worse hands.

7-5 offsuit is far too weak to defend the big blind against a button raise, especially out of position with no postflop edge. Calling 150 more invites reverse-implied-odds spots, so folding is clearly best.

7-5 offsuit is a weak hand not worth playing from the button facing a raise, especially with two players left to act behind.

7h2h is the weakest hand in hold'em and I'm out of position postflop against two players; folding preflop is clearly best.

AKo is a premium hand heads-up versus the big blind after the button folded, so I raise to 3bb for value and to take the initiative.

KJs is strong heads-up against a single raiser; 3-betting builds the pot and applies pressure while I have a hand that plays well multiway or heads-up.

AKo is ahead of a BB 3-bet range and I am out of position, so a 4-bet to 24bb takes the initiative and builds the pot with a premium hand.

Facing a big preflop 3-bet with KJs; the sizing suggests a strong range and calling out of position with a dominated hand is unprofitable.
