Hold'em table

K9 suited is a strong enough button opening hand three-handed, with positional advantage postflop. I raise to a standard 2.5bb size.

KQo is well ahead of a 3-handed button opening range, so a 3-bet for value and initiative works well; calling is also fine. With 100bb stacks, an out-of-position sizing of 10bb is standard.

K9 suited is not strong enough to continue profitably against this very large preflop 3-bet, even with position.

Suited connector on the button, standard raise to isolate the blinds and build the pot in position.

72o is one of the weakest hands, and I'm out of position in the small blind facing a button open with the big blind still to act. Folding is clearly best.

7-3 offsuit is far too weak to defend against a button 3x open, especially out of position.

A5s-ish offsuit ace on the button in 3-handed is a clear open; raise to 2.5bb to steal the blinds.

8-2 offsuit is far too weak to defend from the small blind against a button raise with the big blind still behind.

Q3 offsuit is a weak button holding; folding avoids entering a marginal multiway pot.

Small pocket pair heads-up vs BB after button fold; raise for value/isolation with good implied odds.

Getting 2.5:1 in position against a wide small-blind steal range, 75o has enough equity and playability to defend by calling.

Pocket deuces missed the flop completely; checking to control pot size and see what opponents do.

In position against a check, a small one-third-pot semi-bluff with a gutshot to the ten and a backdoor diamond draw can take the pot now. If called, the hand still has outs.

Pocket deuces have no real equity on this connected JT8-type board facing a bet; folding is cheap and avoids bleeding chips with no pair/draw.

43o is weak and not worth playing out of position preflop even cheaply, with two players still to act behind me.

ATs is a strong hand blind-vs-blind, so I'm raising for value. Going to 3x keeps the pressure on the big blind.

Defend the big blind heads-up versus a small blind 3x raise with suited 86, which has adequate playability and pot odds.

As the preflop raiser I have the range advantage on a king-high board, so a small one-third-pot c-bet makes sense. Ace-high with a backdoor straight draw can fold out better hands and still has equity when called.

We have an open-ended straight draw and are getting excellent pot odds against the small flop continuation bet. Calling in position preserves flexibility while retaining strong implied odds.

Ace-high with no draw on a blank turn after BB called the flop c-bet out of position. BB's calling range has plenty of Kx and pairs that won't fold, so I'll check and keep a little showdown value rather than fire a low-equity second barrel.

Betting our open-ended straight draw applies pressure to missed overcards and weaker pairs while retaining strong river equity when called.

Ace-high with no draw on K-9-7-2 faces a turn bet from a player who called the flop, so they likely hold a pair or better. Calling needs about 27% equity, and with only a handful of live outs I don't have it, so I fold.

KQo on the button in a 3-handed game is a strong opening hand. A standard 2.5x open builds the pot and puts pressure on the blinds.

7-3 offsuit is far too weak to continue from the small blind against a button raise, especially with the big blind still behind.

7c6d offsuit is weak and out of position against a button raise; folding is best given poor equity and implied odds.
