Hold'em table

9c7c offsuit is weak from the button facing a raise-equivalent situation in a 3-handed game; not worth investing chips preflop with a marginal hand.

K7o on the button 3-handed has solid equity and position; a standard 2.5x open pressures the blinds and lets me win the pot preflop or play in position postflop.

KQo is strong enough to 3-bet the button open from the small blind, taking the initiative out of position and denying a cheap multiway flop.

4h Td offsuit is weak, facing a 3-bet to 900 with another player already in; folding preserves chips for better spots.

A9o is ahead of a random button open range in three-handed play, and raising builds the pot with position rather than flat-calling.

Nine-deuce offsuit out of position against a 2.5x button raise lacks the equity and playability to call 150 more profitably; folding is the cheapest line.

Q2 offsuit is a weak hand out of position facing action; not worth continuing in a 3-way pot.

Completing the small blind heads-up with 8-9 offsuit; I only need 50 more into a 150 pot (3:1 odds) and this hand has solid equity against a big blind's wide range.

J4 offsuit is too weak to raise after the small blind completes, and checking is free with position still to come postflop.

I hold an open-ended straight draw (any 5 or T) with no showdown value, so betting ~75% pot as a semi-bluff takes initiative out of position, folds out unpaired hands, and builds a bigger pot when I improve.

Top pair with a weak kicker is ahead of enough of a limp-bet range to continue, and the price is only 150 into 350. Raising folds out worse hands and gets called by better, so I call and use position.

I have jacks and sevens on a paired board and the turn was checked to me, so a half-pot value bet gets called by worse pairs and draws.

A8o on the button in a 3-handed game is a standard open-raise; raising to 3x applies pressure on the blinds and builds the pot with a decent ace.

J3 offsuit is too weak to continue from the small blind against a button open, especially with the big blind still to act. Folding avoids putting more chips in with a dominated, unconnected hand.

J2 offsuit is weak; facing a raise heads-up with a bad hand, folding is correct.

Ten-deuce offsuit is too weak to open even on the button in three-handed play, so folding avoids putting chips in with a hand that plays poorly postflop.

Heads-up pot vs BB with weak but playable King-high; completing cheaply is fine.

A9o is a strong heads-up hand against a small blind limper; raising builds the pot and folds out weak holdings while I still have fold equity.

K3 offsuit facing a raise from BB is weak; not worth calling out of position.
