Hold'em table

A4 offsuit is a reasonable button open in a three-handed game. Raising puts pressure on the blinds while keeping the sizing modest.

J8o is too weak to defend out of position against a button open with the big blind still to act.

97o is too weak to defend out of position against a button open, so folding is the highest-EV option.

Q4o is too weak to open profitably from the button even three-handed, so folding is the standard play.

Button folded, so this is heads-up versus the big blind with T7 suited. A small raise takes the initiative and builds the pot with a playable suited hand rather than just completing.

K9 offsuit is strong enough to defend the big blind heads-up, but calling avoids inflating the pot with a hand that plays better in position-neutral postflop.

I have ten-high with no pair or draw on an ace-high flop, so there is no value in betting. Checking keeps the pot small and lets me see the turn for free.

I have trips and can get value from an ace or club draw while charging draws. A 400-chip bet is a solid size into the 600-chip pot.

I have ten-high with no pair and no draw on an ace-high flop, so calling 400 is burning chips. Seat 1's bet after my check is likely value, and I have no bluff equity worth continuing.

KJo is strong enough to open from the button in a three-handed game. A 3x raise builds the pot and takes the initiative before the flop.

K♠2♥ is too weak to defend the small blind against a button raise, especially with the big blind still to act.

53o is far too weak to defend preflop against a 3x open from the button.

As the button in a three-handed game, 9-8 offsuit is a reasonable open-raise. A raise to 250 puts pressure on the blinds while keeping the sizing modest.

J8o is too weak to defend out of position from the small blind against a button open.

Pocket tens is ahead of a button open and plays best as a value 3-bet to isolate and build the pot before the flop.

9♣8♦ is too weak to continue against the big blind’s substantial 3-bet; the call price doesn’t make up for its poor equity and playability.

72o is the worst starting hand in hold'em and is an easy fold even from the button.

36 suited is too weak to complete out of position against the big blind after the button folds, so I give up the small blind.

On the button in three-handed play, 65o is a marginal but playable open with position; a small raise steals the blinds often enough and keeps the price low when called.

8-5 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act.

3-betting for value from the big blind with pocket kings against a button open.

65o is too weak to continue against a 3-bet to 1000; calling 750 more is not justified.
