Hold'em table

K5 offsuit is weak but on the button 3-handed I can open cheaply for position and fold to resistance. A min-raise keeps risk low while applying pressure on the blinds.

9-5 offsuit is too weak to defend from the small blind against a button open, so folding is the highest-EV option.

63 offsuit is weak facing a raise; folding to save chips rather than defending with a poor hand.

Q5 offsuit is too weak and disconnected to open or flat from the button, so folding preserves chips rather than playing a dominated hand.

Pocket nines is a strong hand heads-up against just the big blind; raising to build the pot and isolate.

Suited one-gapper on the button; raising to build a pot with position and take initiative against two limpers-equivalent blinds.

A2 offsuit is far too weak to defend from the small blind against a 2.5x button raise, with a player still to act behind. Folding loses the minimum.

56o is too weak to continue out of position against a button raise after the small blind folds. Folding avoids a dominated, low-playability spot.

Ace-high from the button in 3-max is a standard opening raise; I'll take the initiative and apply pressure on the blinds.

ATo is strong enough to continue against a button open, and calling keeps the pot small while the big blind is still to act.

AKs is a premium hand; 3-betting for value against an open and a call builds the pot while narrowing the field.

Facing a 3-bet to 1000 with A2o out of position is a clear fold; dominated too often and no suited value.

ATo is dominated too often and plays poorly out of position against a 3-bet, so the pot odds are not enough to continue.

K8o is playable as a button open in three-handed poker, so I raise to 2.5bb rather than limp or fold.

J4o offsuit is a weak hand facing a raise from the button; folding from the small blind is correct here.

T7o is weak, but I only need 150 more to see a flop with a pot already at 400, giving me good odds against a button raise. Calling keeps the pot small with a marginal hand rather than folding away equity.

I flopped top pair with a decent T kicker on a connected 6-5-7 board, so I bet for value and protection against the preflop raiser's range rather than letting free cards improve him.

I have an open-ended straight draw with position and enough pot and implied odds to continue. Calling keeps the pot manageable while I realize equity.

I only hold a pair of sevens with a T kicker, and the turn king likely favors seat_2's preflop-raising range. Checking keeps the pot small and avoids building it with a marginal hand out of position.

I have a straight with the eight on a 5-6-7 board, so I bet the turn for value after seat_1 checks. A roughly two-thirds pot bet can get called by pairs and worse made hands while keeping the pot manageable if a nine has me beat.

I only hold a weak pair of sevens with no real draw, and villain's line (preflop raise, flop call, turn raise into my check) strongly represents a king, overpair, or two pair that dominates me. Calling 800 into a 2050 pot with essentially two outs is unprofitable.

T7 offsuit on the button facing a raise-limp scenario isn't strong enough to invest in; folding preserves chips for better spots.
