Hold'em table

K3 suited is strong enough to open on the button in a three-handed game. Raising to 250 puts pressure on the blinds while preserving position postflop.

J5 offsuit is a weak hand out of position against a button raise, with the big blind still left to act, so folding is best.

J6s is too weak to defend out of position against a 2.5x button open.

J2 offsuit is a weak hand out of position in a three-way pot, and the button gets no reason to call 100 to see a flop with it, so folding is the disciplined choice.

Getting 3:1 direct odds preflop blind vs blind with suited connectors, completing the small blind is standard and profitable.

Checking keeps the pot small with a weak suited hand while allowing me to see the flop for free in position.

I hold a gutshot straight draw out of position in a limped pot, making a standard check the best play to see a turn card cheaply.

After the small blind checks, a half-pot bet can win the pot immediately. My hand has little showdown value but some backdoor potential if called.

I only hold a weak gutshot straight draw with 4d3d on a Th-6s-7c board, giving roughly 8.5% immediate equity against a half-pot bet where 25% direct pot odds are required.

76 offsuit is too weak to open profitably from the button even 3-handed.

Pocket nines are strong heads-up against the big blind, so I’m raising for value.

Q7 offsuit is weak, and calling 200 more out of position against a small blind raise to 3bb (pot 400) would lose money over time. Folding is the simplest choice.

KJo is a strong button opening hand three-handed, so I raise to build the pot while retaining position.

ATo is a strong hand in 3-handed play against a button open. A 3-bet from the small blind takes the initiative and avoids playing out of position in a multiway pot, with the big blind still to act behind.

Q5o is trash facing a button open and an SB 3-bet, trivial fold.

KJo has enough playability to defend against this three-bet in position. Calling keeps the pot manageable without committing to a large four-bet.

Top pair with an ace kicker on a wet T-9-Q board, heads-up and first to act as the 3-bettor. I'll bet about 68% of the pot for value and to charge flush and straight draws.

I have the current nut straight. Raising for value also charges flush draws and other hands that could improve on the turn.

Calling 2600 into a 9700 pot needs about 21% equity. Top-and-second pair with an ace kicker plus a club and straight outs should have that against a flop 3-bet range that includes draws and bluffs, and a shove would risk too much.

I have middle pair with an ace kicker on a wet board, and the opponent's flop raise shows a strong range. Checking keeps the pot manageable and lets me decide against their bet.

I have the king-high straight on a board with a club draw. Shoving for just over half the pot gets value from weaker hands and charges draws before the river.

Calling 5200 into a 14900 pot needs about 26% equity. Top-and-second-pair-ish tens with an ace kicker, plus the Tc blocking some club draws, should beat enough of a raise-heavy range that includes bluffs and draws, so calling is reasonable.

T2 offsuit is a weak hand, and I'm out of position against two players who still have to act after the flop. Folding on the button costs nothing extra.

T4o is too weak to complete or raise from the small blind, so folding is standard.

K2o is too weak to open profitably from the button even three-handed.

A6 offsuit is a strong enough heads-up small-blind hand to raise for value and initiative against the big blind.

K6o is a marginal hand, but the price is good: 200 to call into a 400 pot (2:1) against a small blind raiser's wide range, and I close the action with position on the button folded. Calling is better than a bluff 3-bet or folding.

A small bet gets value from weaker pairs and draws while protecting top pair with a weak kicker.

Ace-high with a king kicker and a backdoor draw is a reasonable bluff-catcher. The price is 200 into a 800 pot, and a small c-bet from the small blind is often weak, so calling is better than folding or bloating the pot.

Top pair with a weak kicker can get value from weaker pairs and draws. A moderate turn bet also makes drawing more expensive without building an oversized pot.

Ks with Ad on board gives me only king-high, but I have a gutshot to a 4 with the 6 (A-3-5-6 needs a 4 for the wheel... 2 also), so a call with pot odds of 1400+400 to 400 (about 4.5:1) is reasonable versus a wide small-blind betting range. Raising is unwarranted.

My weak top pair has showdown value, but the river completes the diamond flush and makes a value bet unlikely to get called often by worse. I’ll check rather than build the pot.

King high has a little showdown value against a checking range that includes missed draws. A bet would only fold out hands I beat and get called by better hands, so I check.
