Hold'em table

Ace-ten offsuit is a strong button open in three-handed play, so I raise to 3x the big blind to build the pot and take the initiative.

Holding 72o out of position facing a raise to 3bb is an easy fold.

JTo is a reasonable big-blind defend against a button raise. Calling gets a favorable price while avoiding an unnecessary out-of-position 3-bet.

I have top pair with a reasonable kicker, but the preflop raiser can continuation-bet and I’m out of position. Checking keeps their bluffs and weaker hands in the pot while avoiding an unnecessary lead into a strong range.

Top pair with the ace kicker on a dryish flop; a small c-bet gets value from worse tens and draws while keeping the pot controlled.

Top pair with a reasonable kicker is strong enough to continue against this modest flop bet, though raising risks isolating myself against stronger hands on a two-heart board.

The ace is a poor turn card for my middle pair, and checking keeps the pot manageable while preserving showdown value.

I have top two pair on a dry board and the opponent checked again, so I bet about two-thirds pot for value.

The ace is a strong turn card for the preflop raiser’s range, and this sizable bet leaves my pair of tens with weak showdown equity and no meaningful draw. I fold rather than pay off likely Ax or better.

King-Ten offsuit is well within the standard button opening range in 3-handed play. Raising to 2.5bb applies pressure and captures positional advantage.

Q5 offsuit is weak and dominated often, especially out of position against a button raise. The 200-chip call is not worth it.

K2o is too weak to continue against a button open; calling or raising would be dominated and poorly playable out of position.

Q2 offsuit is a weak holding, and opening into both blinds risks building a pot with poor playability. Fold rather than call out of position postflop.

K3 offsuit is too weak to continue out of position for even a small blind complete after the button folds. Folding avoids playing a dominated king with poor playability.

T9o is playable on the button in three-handed play, so I open-raise rather than limp or fold. A 2.5bb raise builds the pot with position and can take it down preflop.

65 offsuit is too weak to defend out of position from the small blind against a button open.

K8 offsuit is a reasonable big-blind defend against a small button open, and the pot odds make calling preferable to folding. I avoid 3-betting this marginal hand out of position.

I have only king-high with no useful draw on an ace-high flop. Check and avoid building the pot with a weak hand.

Middle pair with a ten kicker on an ace-high flop has some showdown value, but betting into the big blind's calling range is thin and risks a raise. Checking keeps the pot small and realizes equity.

I have only king-high with no meaningful draw, and checking keeps the pot small while preserving the chance to improve on the river.

I have aces and nines on a checked-through turn, ahead of most of the BB's continuing range. A half-pot bet gets value from worse pairs and draws while keeping the pot manageable if they wake up with an ace.

K-high has little showdown value on this paired-ace board, and I have no meaningful draw. The turn bet is not worth calling with only a few uncertain improvement cards.

Opening from the button with KQo to 2.5bb is standard and profitable in 3-handed play.

7♦3♣ is a very weak offsuit hand, and calling 200 chips out of position against a button raise is not worthwhile.

K2o is too weak to continue out of position against a button open; folding avoids a dominated, low-playability spot.

8♣3♦ is a weak offsuit hand, and calling 100 chips from the button would be unprofitable against the blinds.

Q6o is too weak to continue out of position after the button folds; calling or raising leaves me dominated and poorly placed postflop.
