Hold'em table

J8o on the button in a 3-handed game is a reasonable open; raising to 2.5bb takes initiative and pressures the blinds with position.

Qs3c offsuit is too weak to continue versus a button open, especially out of position with the big blind still to act.

Pocket fives in the big blind against a 2.5x raise: set-mining odds are fine, and calling keeps the pot small with a speculative hand.

I have 55 on an AK2 flop, only an underpair with no draws, so I'll check and fold to aggression rather than invest more.

I raised preflop from the button and BB checked to me on an Ace-high flop that favors my range; a small continuation bet with J8 offside folds out many hands that missed while risking little.

Pocket fives have almost no equity on an A-K-2 board against a preflop raiser's flop bet; folding now is cheapest.

K2o is too weak to open from the button; folding avoids a dominated, poorly connected hand out of position postflop.

5d3d is a weak trash hand on the button facing blinds; folding is the highest-EV play.

Button folded, so it's SB vs BB heads-up; KJo is a clear raise for value and to take initiative. Raising to 3bb is standard.

56o is too weak to continue against a 3bb small-blind raise; pot odds are close but the hand plays poorly postflop.

Q5 offsuit on the button in a 3-handed game is marginal; it's below a standard button opening range and plays poorly, so folding avoids a dominated spot.

Button folded, so I am heads-up versus the big blind and only need 50 more into a 200 pot. Ten-deuce suited has enough equity and playability to complete rather than fold.

J5s is a weak hand in the big blind; checking to see a free flop heads-up is better than raising out of position.

Bottom pair with a weak kicker on a monotone club flop has little value to bet; checking keeps the pot small and sees what the big blind does.

J5 high on a monotone board with no equity; checking is free and avoids building a pot out of position.

I have only a weak pair of deuces on a paired, queen-high board, so there is little value in betting. Checking keeps the pot small and preserves a cheap showdown.

J-high with no draw on a paired, monotone-ish board; checking is free and avoids building a pot I likely lose.

I have only a pair of twos on a paired, three-flush board, so there is no value in betting. Checking keeps the pot small and lets me reach showdown for free if seat 3 also checks.

J5s missed the board entirely; I have only a busted bluff-catcher. Checking behind keeps the pot cheap and avoids burning chips into seat_2's likely made hand.

Q8o is playable as a button open in three-handed poker; a small raise takes the initiative and can fold out weaker hands.

J7 offsuit is too weak to call 200 more against a 2.5x raise from the button; folding preserves chips.

6c2c is a weak suited hand out of position against a button raise; the pot odds (150 to win 400) are okay but the hand's playability and equity realization OOP are poor, so folding is fine.

A7s on the button is a standard opening raise; I'll take the initiative and build the pot in position.

JJ in the small blind facing a button open to 3bb is a clear 3-bet for value; raising to 10bb builds the pot in position-disadvantaged spot while denying the BB a cheap call.

A6o is too weak to continue against a button open and a small-blind three-bet to 1000. Folding avoids putting 900 more into a dominated ace.

A7s is too weak to continue against a 3-bet out of position; folding and preserving chips is the profitable play.
