Hold'em table

Button raise with Q8o in a 3-handed pot to apply pressure on the blinds; a standard sized open gives me position and fold equity.

96 suited is too weak to continue out of position against a button open, with the big blind still to act. Folding avoids paying 200 into a dominated spot.

7-2 suited is one of the weakest hands; facing a 2.5x button open from the big blind, folding is standard despite decent pot odds since the hand plays poorly out of position.

Button open with suited jack in a three-handed pot; a small raise steals initiative cheaply and can fold out weaker blinds.

7-2 suited is one of the worst starting hands; facing a 2.5x button open from the small blind with the big blind still to act, folding is clearly correct.

96 suited offsuit-like weak hand facing a raise from the button with a cold call needed; not worth continuing out of position.

K8o on the button in a 3-handed game is a standard open; raising to 2.5bb takes initiative and pressures the blinds.

J5 offsuit is a weak hand facing a raise and a call cost; not worth continuing out of position.

J6 offsuit is too weak to continue against a button open after the small blind folds.

Button open with a wide range in 3-handed play; K5o is a reasonable steal attempt against two players who have only posted blinds.

5-7 offsuit is too weak to call a button open with the big blind still to act.

Button opens to 2.5bb, SB folds; I'm in the BB with J8o getting 400:150 (~2.7:1) pot odds, which is a standard defend against a button open range despite being out of position.

I have J8 offsuit with no pair on a paired A-high board, out of position against the preflop raiser. Checking is standard; leading into the raiser with air on an ace-high board is poor, and I can fold to a bet or bluff later if checked through.

I have no pair but the ace-high board favors my preflop raising range; a continuation bet can take down the pot against a checking opponent.

J8o has no pair, no draw on a 9-9-A board facing a continuation bet; our equity is poor against a button opener's range and folding is clearly best.

A5s is a strong suited ace to open from the button first to act; a 3bb raise builds the pot and applies pressure before the blinds.

J7 offsuit in the small blind facing a 3x button open is a clear fold; it plays poorly out of position and is dominated by a typical button raising range.

5d7h offsuit is weak, facing a 3x raise with poor pot odds and no position; fold.

54 offsuit on the button in a 3-handed game is a marginal hand; it's below a standard button opening range and plays poorly out of position vs blinds who may 3-bet. Folding avoids a -EV spot.

K7o is weak but cheap to see a flop heads-up against the big blind; just completing the small blind.

94s is too weak to raise out of position against a small-blind limp, and there is nothing to call, so I check and see a flop.

I have no pair and only a backdoor draw; checking to control pot size against two opponents.

94 hearts has no pair or real draw on A-7-T, and the small blind already checked. Checking behind is free and avoids bloating a pot I am unlikely to win.

I only have a weak pair of sevens with a king kicker; checking keeps the pot small and controls risk against two opponents who've shown little strength.

I have 9-4 with no pair and no real draw on an ace-high board, so checking back is the highest-EV line.

I have two pair, kings and sevens, a strong hand on this runout; opponent has checked every street so I can bet for value.

I have nine-high with no pair or draw on a board that has an ace and a king, so calling a river bet is unprofitable.
