Hold'em table

K3o is too weak to open from the button even in 3-handed play.

J2 suited is weak and would be out of position against the big blind for the rest of the hand. Folding is a small loss, since I've only put in the 50 small blind, and it avoids marginal spots.

6-3 offsuit is one of the weakest hands, and I'm out of position against two players who still have to act after the flop. Folding costs nothing on the button here.

AJs is strong heads-up against the big blind. Raising from the small blind builds value and puts pressure on weaker hands.

In a blind versus blind situation, A4o has solid equity and positional advantage to defend against the small blind's raise.

A small continuation bet can fold out weaker overcard hands while keeping the cost low on a board that also connects with the big blind's range. A♣J♣ has two overcards and a backdoor flush draw if called.

Holding just Ace-high and a weak gutshot straight draw with poor implied odds, calling a flop bet is unprofitable.

J8 offsuit is strong enough to open on the button in a three-handed game. A 2.5 big blind raise applies pressure while keeping the pot manageable.

A6s has strong blocker value and good playability, making it an excellent 3-bet candidate from the small blind against a button open.

Facing a button open and a small blind 3-bet to 800 with a button caller still to act, calling 700 more out of position with JTc is marginal, and a 4-bet bluff is poor. Folding is the disciplined choice.

J8 offsuit is too easily dominated by the small blind’s three-bet range, and calling leaves a weak hand in a large pot.

Ad Jc is a premium hand on the button in 3-handed play; raising to 2.5 big blinds is standard to build the pot and apply pressure.

J5 offsuit is a weak hand out of position against a button open, with the big blind still to act behind me. Folding costs only the 50 chip small blind.

8-3 offsuit is too weak to defend out of position against the button's raise.

2-5 offsuit is one of the weakest hands, and I'm out of position on later streets against two opponents. Folding on the button costs nothing extra.

A8 offsuit is strong enough to raise heads-up against the big blind, and 3× the big blind puts pressure on their wide range.

Getting 2:1 pot odds in position against a blind-versus-blind open, A4o has sufficient equity to justify a defend.

Ace-high has some showdown value on this dry flop, so I prefer to check rather than turn it into a bluff.

I have middle pair with an ace kicker and a gutshot straight draw, so checking behind in position controls the pot size and realizes equity.

Ace-high has some showdown value, and a five gives me a straight. Checking avoids building a pot out of position with a weak hand.

I have third pair with an Ace kicker and a gutshot straight draw; checking behind controls the pot and realizes equity in position.

The river gives me a wheel. A 400-chip value bet can get called by a king or two pair, while keeping the cost modest when an opponent holds a six.

I hold a five-high straight with Ah. While any six makes a higher straight, the opponent's range includes worse value bets like kings, chopped pots with other aces, and bluffs, making calling the 400 chip bet profitable getting 2.5:1.

K2 offsuit is too weak to open from the button against two unknown blinds at 100 big blinds.

Nine-four offsuit is too weak to complete or raise from the small blind out of position.
