Hold'em table

Ace-five suited is a strong button open; a 2.5bb raise builds the pot and takes initiative before the blinds.

92 suited from the small blind facing a button open, with the big blind still to act behind, is a clear fold. Calling out of position with a weak hand is unprofitable.

73s is too disconnected and weak to profitably defend out of position against a 2.5x button open.

A3o on the button in 3-handed is a clear open; raising to 2.5bb puts pressure on the blinds.

T5o is far too weak to defend out of position against a button open.

ATo is strong enough to continue against a button open, and calling keeps the pot small while realizing equity in position disadvantage. Folding is too tight and a 3-bet risks domination without enough fold equity.

Ace-high with no pair or draw on a king-high flop is too weak to donk into the preflop raiser, so I check and realize equity.

On a dry K64 rainbow board I have the range advantage as the in-position preflop raiser, and A3 adds a gutshot plus an overcard. A small c-bet of about a third of the pot should take it down often.

Ace-ten missed this king-high flop with no pair or draw, and I am out of position against a preflop raiser. Calling the small c-bet is speculative without enough equity or a clear plan on later streets.

Opening from the button with an Ace in 3-handed play is standard to apply pressure on the blinds.

T6o is too weak to continue out of position against a button open, especially with the big blind still to act.

KTo in the big blind facing a 2x button open is getting 4.5:1 pot odds and is well ahead of a wide button range, so calling is clearly profitable. A 3-bet is possible, but calling keeps their dominated hands in.

K-high with a gutshot on a paired board out of position against the preflop raiser; checking keeps the pot small and lets me see the opponent's action.

Check behind with Ace-high and weak kicker to control pot size and realize showdown value.

The button checked back the flop, which caps their range with many unpaired overcards like Ax. A small probe bet can fold out hands that beat our king-high, and the deuce is a safe card to keep telling a 7 story.

Holding just Ace-high with a four kicker on a paired board facing a turn bet with no draw, folding is standard.

K6o is too weak to call or open from the button against two live blinds; folding avoids dominated spots and preserves the stack.

Pocket threes are well ahead of a random big blind hand heads-up, so raising to 3bb from the small blind takes the initiative and can win the pot right away.

Defending A3o in position against a small blind open, getting 2:1 pot odds.

Our 33 makes fours-full-of-threes, which is strong against BB's unpaired hands but vulnerable to overcards pairing on later streets. A small c-bet on this triple-paired board charges those hands and gets value.

We hold trip fours with an ace kicker on 4-4-4; calling a small c-bet in position is standard against a wide SB range.

On 444A, 33 only beats unpaired hands and 22. Any ace, pocket pair above threes, or four beats us, and those are hands that call. Checking controls the pot and lets the bluffs in the BB's flop-calling range keep betting.

We turned a full house (fours full of aces) with our Ah, chopping with any Ax. Checking back keeps the opponent's weaker holdings and bluffs in the hand for the river.

Our 33 makes fours full of threes, but any ace, king, or pocket pair above threes beats it. A bet would mostly get called by better hands, so check and treat the hand as a bluff-catcher.

We hold Fours full of Aces, but after the turn and river check-through, worse hands like missed broadways will fold and pocket pairs may not call, while we risk running into traps like KK. Checking behind realizes our showdown value safely.

In 3-handed play, 65 offsuit on the button is a reasonable steal hand against two blinds. A small open puts pressure on them and keeps position.

A4 offsuit plays poorly out of position against a button raise with the big blind left to act, making fold the standard play.

Ten-deuce offsuit is too weak to continue out of position against a preflop raise, so folding preserves chips.

9-3 offsuit is well outside any reasonable opening range on the button in 3-handed play, making fold the clearly superior option.

K3 offsuit is too weak to continue out of position for another half-blind; the posted small blind is a sunk cost.
