Hold'em table

K4o is too weak to open profitably from the button even in 3-handed play.

The button folded, leaving a blind-versus-blind pot. With 3:1 pot odds, completing with 9♦4♠ is preferable to folding, though raising is unattractive.

Button folded and the small blind limped, so I raise T8s from the big blind to take the initiative with position and a playable suited hand.

9♠4♦ is a weak offsuit hand, and calling 300 more out of position against a 4bb raise is not worthwhile.

4-5 offsuit is too weak to open profitably from the button, and calling would invite the blinds to realize equity against a dominated hand.

Q2 offsuit is too weak to call or raise out of position against the big blind after the button folds.

Q2 offsuit is too weak to open from the button even three-handed; folding avoids paying the big blind with a dominated, poorly connected hand.

Q4o is too weak to complete or raise from the small blind out of position against the big blind.

J7o is too weak and disconnected to profitably open from the button, making fold the standard play.

With the button folded, A4o is a reasonable small-blind raise heads-up against the big blind. Raising to 250 applies pressure while keeping the sizing modest.

King-four offsuit is too weak to continue out of position against a raise; raw equity is marginal and postflop realization is poor.

Calling cheaply from the button preserves position and gives this weak hand a chance to improve; raising would be too ambitious with 2♣3♦.

43o is too weak to complete from the small blind out of position after a button limp, with the big blind still to act. Folding avoids a poorly playable multiway pot.

I have 6h 5c in the big blind facing a button limp and SB fold. Checking gives a free look at the flop.

Flopped an open-ended straight draw out of position; checking to realize equity and see how the button reacts.

A small stab can fold out some unpaired hands, and I have a gutshot to a five if called.

We flopped an open-ended straight draw with 8 clean outs and are getting 3.5 to 1 direct pot odds on a min-bet.

I turned a seven-high straight on a board of A-7-4-3. I lead for value into the limper to build the pot and charge potential draws.

A bottom pair is unlikely to be ahead of a turn lead after the opponent called the flop, and I have very few clean improvement outs. The call price is not attractive against their likely Ax or other made hands.

J8o is a reasonable button open in three-handed play; a small raise takes the initiative and can win the blinds without committing much.

Q2s is too weak to defend out of position against a button open with the big blind still to act.

8♣5♥ is a weak offsuit hand with poor playability, and calling the 2.5x button raise out of position is not worthwhile.
