Hold'em table

Button with A5o, raising to 2.5bb to steal blinds and apply pressure in a 3-handed game.

A3o is too weak to continue out of position against a button raise with the big blind still to act, so folding avoids dominated spots.

T2o is too weak to continue against a button open; calling 150 into 400 is -EV and a raise has no equity or playability.

5-2 suited is too weak to continue, even on the button; folding avoids playing a dominated hand out of position postflop despite the small call.

Button folded, so this is heads-up versus the big blind. Ace-eight offsuit is strong enough to raise for value and fold equity rather than just complete.

A8o is a playable hand heads-up in position against a small blind raise. Calling keeps the pot manageable and allows us to evaluate the flop.

I flopped two pair with an ace kicker and only one opponent. A two-thirds-pot bet builds the pot while charging draws and weaker pairs.

I have top pair with top kicker on a dry paired board and position. Calling keeps worse hands and bluffs in while avoiding inflating the pot against overpairs or trips.

I have two pair, eights and fours, with an ace kicker, and the opponent has called both streets. A half-pot bet gets value from worse pairs and draws while keeping the pot manageable if they have a nine.

A5o is playable as a button open in three-handed poker; a 2.5bb raise takes the initiative with position rather than calling or folding.

K7o is too weak to call or raise from the small blind against a button raise, especially out of position; better to conserve chips for a stronger spot.

J5o is a weak offsuit hand facing a 2.5x button raise; folding avoids playing a dominated hand out of position.

K2o is a very weak hand, and even with position it's unlikely to steal the blinds effectively against two opponents. Folding preserves my stack for more profitable opportunities.

With only the big blind left and a weak K6 offsuit, a raise applies pressure and can take the pot down preflop; if called, I have position and can evaluate the flop.

82 suited is too weak to continue against a preflop raise for 200 more.

T5o is a weak offsuit hand that plays poorly multiway and is dominated by many calling/raising ranges. Folding avoids investing chips out of position in a marginal spot.

A2o out of position against the big blind is too weak to complete or raise; folding avoids dominated reverse-implied-odds spots.

AQs on the button is a strong open; a 3x raise builds the pot and applies pressure before the blinds can see a free flop.

9d6h is too weak to call or raise out of position against a button open.

Q3o is too weak to defend against a button raise out of position, and calling 200 more would often leave me dominated. Folding preserves chips for better spots.
