Holdem table

K2 suited is a profitable button open three-handed, and a 2.5 big blind raise applies pressure while keeping the pot manageable.

AJs suited is a strong 3-bet candidate from the small blind versus a button open, applying pressure while retaining strong equity when called.

A9s facing an open and a 3-bet, with the button still to act behind, plays poorly: it is often dominated and in a multiway pot. Folding is the disciplined choice.

K2 suited is too weak to defend against the small blind's three-bet at this price.

Open-raise the button with suited 6-5, which has solid playability and benefits from initiative in a three-handed game.

A2 suited plays well as a 3-bet bluff from the SB against a button open, since the ace blocker cuts down strong continuing ranges and the hand keeps some playability when called. Calling out of position with the BB still to act is worse.

Six-three suited is too weak to defend out of position against a large three-bet, especially with the original raiser still to act.

Suited 65 has adequate playability in position against the small blind's 3-bet, especially with deep stacks. Calling retains implied odds rather than inflating the pot preflop.

As the preflop 3-bettor I have the range advantage on a K-J-4 board, so a small c-bet of a third of the pot works well. Ace-high with a backdoor heart draw is a good candidate for that bet.

Six-high with only a backdoor club draw has insufficient equity against this substantial flop continuation bet in a 3-bet pot.

On the button in 3-handed play, 65o is a reasonable steal candidate against two blinds; a small raise to 2.5bb pressures them and keeps our losses small when we fold to a 3-bet.

T4 suited is too weak to defend from the small blind against a button raise with the big blind still to act.

Ace-king suited is a premium hand and a clear value 3-bet from the big blind versus a button open. Raising builds the pot while applying pressure to weaker opening hands.

65o is too weak to continue against a large 3-bet from the big blind, even in position; offsuit connectors realize their equity poorly here.

A6 offsuit is strong enough to open on the button three-handed. A 2.5-big-blind raise applies pressure while keeping the pot manageable.

KQo is a strong enough offsuit broadway to 3-bet from the small blind against a button open, gaining initiative and denying equity to the big blind.

K4o facing an open and a 3-bet from the small blind is too weak to continue, and the original raiser can still act behind me.

A6 offsuit is often dominated by a small-blind three-bet range and plays poorly in a large pot, even in position.

6-2 offsuit is too weak to open from the button in this structure, so folding avoids investing chips with poor equity.

J8o is a fine blind-vs-blind open from the small blind; raising to 3bb takes the initiative and folds out weaker hands.

A4 offsuit is worth defending against a small-blind raise, and I’ll have position after the flop.

Middle pair with a weak kicker, out of position against the big blind's calling range on a Q-high board. Checking controls the pot size and keeps my range protected.

Ace-high has some showdown value, but this flop gives me little reason to build the pot. I'll check in position and see the turn.

Second pair (jacks) is likely ahead after the flop checked through. A half-pot bet gets value from weaker pairs and draws and protects against overcards.

Ace-high has no meaningful draw on this turn, and calling 300 is unlikely to be profitable against a turn bet.

ATo on the button in 3-handed is a clear open-raise; 2.5bb standard sizing.

K9 offsuit is strong enough to defend the small blind against a button raise, but not strong enough to build a large pot out of position.

A9 offsuit has ample equity and favorable pot odds to defend the big blind against the raise and caller. Calling keeps the pot manageable while retaining a strong ace.

With king-high on a coordinated flop against two opponents, I prefer to check rather than build the pot.

I have the nut-heart draw plus a gutshot, giving strong equity when called. A two-thirds-pot semi-bluff can also fold out unpaired overcards and weak pairs.

Ace-high with only a weak backdoor straight draw facing a multiway donk lead, and the SB can still act behind. There's too little equity to continue.

K9 offsuit has no pair or immediate draw on this wet flop. Calling 500 out of position against a bet into two players is unlikely to be profitable.
