Hold'em table

Jacks are a strong hand in 3-handed play on the button, so I raise for value to 3x the big blind and build the pot against two blinds.

32 suited is too weak to call a button 3x from the small blind out of position with the big blind still to act.

9-3 offsuit is far too weak to defend from the big blind against a button open, even getting 2.25:1; it plays poorly postflop out of position.

8-4 offsuit is a very weak hand even on the button in 3-handed play; calling 100 chips has negative expected value against the blinds.

Button folded, so it's SB vs BB heads-up; T8o is a standard raise from the small blind in this blind-vs-blind spot to take initiative and pressure the BB.

K3 offsuit is a marginal hand, but the price is good: 200 to call into a 400 pot (2:1). The small blind's 3x raise is wide, and K-high has decent equity against that range, so I call and keep the pot small.

Second pair with a decent kicker on a dry K-high board heads-up; a small 1/3-pot c-bet gets value from draws and worse pairs while keeping the pot manageable out of position.

Top pair with a king on a K-T-7 board is strong enough to continue against a small continuation bet from the small blind. Calling 200 into a pot of 800 gets a good price and keeps weaker hands in, rather than raising and folding out worse.

Second pair with a weak kicker on a K-high board after getting called on the flop; betting again is thin and bloats the pot out of position, so check for pot control and evaluate versus a bet.

Top pair on a dry board, heads-up against a player who checked the turn after betting the flop. A bet of about half the pot gets value from weaker pairs and draws, and it denies equity to hands like a missed straight draw.

Second pair facing a half-pot stab after I checked; getting 3:1 I only need ~25% equity and opponent's range includes draws and floats, so calling to see the river is correct while raising or folding both seem worse.

Tens with a weak kicker is a marginal showdown hand; betting only gets called by Kx or better tens, while checking lets missed draws bluff or show down for free.

I have trip kings with a 3 kicker on a Ks Tc 7h 4c Kh board. Seat 3 checked the river after calling the turn, so their range is capped, and many worse Kx and Tx hands will call a bet of about half the pot. I'm betting for value.

I hold kings and tens; the river bet is small (about a third of pot) so I need under 25% equity, and opponent's range includes missed straight draws and weaker pairs along with the Kx/boats that beat me. Calling is clearly profitable; raising would only get called by better.

T8o on the button in a 3-handed game is a reasonable steal candidate against two blinds; a 2.5x open takes the initiative and often wins the blinds outright.

J9 offsuit out of position in the small blind facing a button open, with the big blind still to act behind, is a marginal hand that plays poorly. Folding avoids a costly spot.

7-4 suited is too weak out of position against a button raise; despite the small price, postflop equity realization is poor.

K3 offsuit is a weak hand out of position postflop against two opponents; folding on the button is the disciplined choice, though a call would be only marginally worse.

6-4 offsuit is well below a profitable small-blind open range when out of position against the big blind, so folding saves the additional chips.

86 offsuit is a weak gapped hand even on the button in 3-handed play; folding avoids a negative-EV open or limp against the blinds.

Button folded, so it's SB vs BB heads-up; J8o is a standard open-raise in this spot to take the pot or play in position-equivalent blind-vs-blind dynamics.

7-2 offsuit is the worst starting hand. Calling 200 more into a 400 pot would be out of position with little equity, so folding is best.

A4 suited on the button in a 3-handed game is a standard open-raise; raising to 2.5bb takes initiative and lets me play in position.

J3 offsuit is a weak hand out of position against a button raise with a big blind still to act, so folding is best rather than paying 200 more.

KTo has strong equity against a wide button 2.5x open and good pot odds closing the action heads-up, so calling to defend the big blind is preferable to folding or bloating the pot out of position.

Out of position with king-high and no direct draw on a queen-high two-club board, checking preserves pot control and lets the preflop raiser reveal strength.

Checked to me on a dry Q-high flop as the preflop raiser; A4s has backdoor flush/straight equity and an ace overcard, so a small c-bet takes down the pot often and builds a pot cheaply when we improve.

King-high with no pair and only backdoor straight potential has insufficient equity against a half-pot flop bet on Q-8-2 with a flush draw.
