Hold'em table

73o is too weak to open even from the button in a three-handed game, so folding avoids putting chips in with a dominated offsuit hand.

72o is the worst hand, and from the small blind against the big blind it plays poorly out of position. Folding loses only the 50-chip blind already posted.

In 3-handed play, K4o on the button is a standard open against two blinds, so I'm making a small 2.5bb raise to steal.

T8 offsuit is too weak to defend profitably from the small blind against a 2.5bb button raise with the big blind still to act. Folding avoids poor equity realization out of position and the risk of a squeeze.

Q8 offsuit is too weak to continue out of position against a button open; folding saves chips.

J3 offsuit is too weak to open profitably on the button without evidence that the blinds overfold. Folding avoids investing in a hand with poor playability and frequent domination.

Button folded, so this is heads-up versus the big blind. 79o is weak but the extra 50 chips is a cheap complete with decent playability.

A2 suited is well ahead of a small blind limping range, so raise for value and initiative while in position against the limper.

97 offsuit is too weak to continue out of position against a raise to 400 after completing the small blind. Folding avoids putting more chips in with a dominated, low-equity hand.

58 offsuit is too weak to open from the button for a full big blind, so folding preserves chips.

K4o is a standard SB open versus a lone BB in blind-vs-blind play; raising to 3bb applies pressure and takes the initiative.

Six-deuce suited is too weak to profitably defend against a 3bb raise without evidence the small blind is opening excessively wide. Its poor connectivity and low-card strength outweigh the benefit of position.

A3o on the button 3-handed is a clear open; raising to 2.5bb steals the blinds often and plays fine in position.

97 suited is a marginal small-blind defense against a 2.5bb button raise, with the big blind still able to squeeze. Folding avoids investing more with a weak hand that must play out of position.

Nine-three offsuit is too weak to continue against a button open after the small blind folds, so folding saves the extra 150.

Pocket jacks are a strong value open on the button three-handed. Raising to 2.5 big blinds builds the pot against weaker hands while retaining positional advantage.

KTo has enough playability and pot odds against a button open in three-handed play to continue rather than fold or inflate the pot.

J2o out of position in a three-way pot realizes its equity poorly. The 20% price isn't enough to justify continuing with such a weak, dominated hand.

Top pair with a ten kicker on a draw-heavy flop; a two-thirds pot bet builds value and charges flush and straight draws while I am out of position.

JJ is a weak bluff-catcher on this two-overcard flop, and holding two jacks blocks natural straight-draw bluffs. Against a two-thirds-pot lead, our limited improvement prospects and vulnerability to further betting favor folding.
